Women on top<br />

THIRTY-FIVE YEARS after the Russian cosmonaut<br />

Svetlana Savitskaya was the first<br />

woman to take a spacewalk, a new historical<br />

event took place above our heads on 18 October<br />

<strong>2019</strong>. Two Nasa astronauts took the<br />

first all-female spacewalk. It was not just for<br />

fun, Christina Koch and Jessica Meir were<br />

responsible for replacing defective equipment<br />

from the International Space Station<br />

(ISS), and in that way also formed the first<br />

female maintenance team in the space.<br />

Construction of the International Space<br />

Station began in November 1998 and was<br />

put into service two years later by the first<br />

crew. Keeping this gigantic facility operational<br />

is not easy (*). There were major<br />

problems with an air leak in 2004, smoke development by the oxygen generator in<br />

2006 and life-threatening computer problems in 2007 caused by condensation in<br />

some electrical connectors. Some repairs require extra-vehicular activities (EVAs).<br />

For example, in 2010 and 2013 there was a problem in an ammonia cooling circuit,<br />

which required several space walks to replace a defective pump unit. So far, there<br />

have been more than 1,000 hours and almost 200 space walks to perform modifications<br />

and repairs on the outside of the station.<br />

Congratulations from the Big Chief<br />

Koch and Meir had to replace a defective battery charging and discharging unit<br />

(BCDU) mounted on a truss on the outside of the ISS. BCDUs control the amount of<br />

energy stored from the solar panels in the batteries. The defect was caused by a previous<br />

replacement of a set of lithium-ion batteries. Because of the weightlessness<br />

and absence of friction, working in space is not easy. The entire mission was meticulously<br />

prepared and the general public could follow a lifestream of the astronauts,<br />

dangling at 420 km above the earth’s surface, carrying out the repairs.<br />

During the works, the NASA astronauts received a phone call from President<br />

Donald Trump, who congratulated them on the historic spacewalk: “What you do is<br />

incredible”. As far as I’m concerned, a lot of CEOs could take Trump as an example<br />

and give their maintenance workers more often a pat on the back for their valuable<br />

work.<br />

Feminize the technical world<br />

After the mission there was a lot of praise for the historical spacewalk. However,<br />

there was also criticism because it took more than 44 years after the first space walk<br />

before two women could go on a spacewalk together. This apparently had to do with<br />

the fact that the space suits were made to measure for a man’s body. During an interview<br />

before the space walk, Christina Koch put her finger on the wound: “In the<br />

past, women have not always sat at the table...”.<br />

We urgently need to get rid of the stereotypical image that only men are suitable<br />

for technical work. Let’s all work on this consciously. For example, by actively looking<br />

for female technical talent. However, this will not be enough to get more female<br />

maintenance technicians and engineers on the shop floor. After all, the image of<br />

typical female or male professions starts at a young age. Specialists point out that it<br />

is important to consciously avoid stereotypes from childhood onwards. And you can<br />

do something about that too. Maybe YOU can start in the upcoming holiday season<br />

by asking Santa Claus to bring your (grand)daughter a cool set of tools and matching<br />

tool belt? A valuable present that could launch her future career to the top...<br />

Approach to Online<br />

Monitoring of<br />

Roller Bearings in<br />

Wind Turbines<br />

Text: Dr. Edwin Becker and Dipl. Ing. Michael Dietl,<br />

PRÜFTECHNIK Condition Monitoring GmbH<br />

PARTNER ARTICLE<br />

As highly stressed components, roller bearings in the drive train of wind turbines<br />

are subject to countless influences from ‘manufacture, assembly, and operation.’<br />

BEARING-SPECIFIC CHANGES in state can<br />

be detected at a relatively early stage<br />

through traditional structure-borne<br />

noise-based methods of roller bearing<br />

monitoring and diagnosis. In the context<br />

of large-scale monitoring, various<br />

data-driven procedures help to prioritize<br />

irregularities by extracting characteristics<br />

from measured overall readings and<br />

diagnostics, assigning them to defined<br />

roller bearing conditions based on standards<br />

and guidelines. However, there are<br />

powerful continuous measuring CMS<br />

systems, which work as edge devices<br />

while support IIoT relevant protocols,<br />

such as MQTT. The costs associated<br />

with repairs on planetary stage bearings<br />

in the main gear and with rotor blade<br />

bearings are elevated. Please refer to<br />

Figure 1 to see the correlation between<br />

the frequency of bearing damage and its<br />

financial implications.<br />

How does this happen?<br />

Sporadic patterns in wind speed force<br />

the components within wind turbines<br />

to be highly dynamic, allowing them to<br />

adapt to variating load ratios and running<br />

speeds. These substantial fluctuations<br />

result in elevated vibration, effectively<br />

causing high levels of stress to the<br />

roller bearings and making them susceptible<br />

to being the most common cause of<br />

damage to the drive train. Historical evidence<br />

would suggest that roller bearing<br />

on the gear outlet of the fast drive train<br />

side is the component in wind turbines<br />

that experiences the most frequent premature<br />

damage.<br />

3 Factors of mechanical service life:<br />

All mechanical components are heavily<br />

impacted by three factors: Manufacturing,<br />

Assembly and Operations.<br />

Manufacturing encompasses all factors<br />

determined in the bearing’s production<br />

phase from dimensional accuracy to the<br />

radial clearance. Assembly relates to the<br />

installation of the bearing, errors made<br />

in the fit and inclination of the bearing<br />

can lead to severe distortion. Lastly, operation<br />

pertains to the overall usage of<br />

bearing, Figure 2 summarizes the factors<br />

at play and their corresponding criticality<br />

levels. Please note that as apparent<br />

in many instances of mechanical failure,<br />

the causal factors of the damage all prove<br />

to be interconnected.<br />

Traditional vibration methods<br />

for roller bearing condition<br />

diagnostics<br />

Rotating roller bearing components<br />

generate measurable, high frequency,<br />

and structure-borne sound vibrations as<br />

a result of rolling, friction, and impact on<br />

the roller bearing. During roller bearing<br />

diagnostics, structure-borne noise measurement<br />

methods can be used to detect<br />

roller bearing damage at early stages.<br />

The critical metrics to monitor include:<br />

envelope spectra, and time signals with<br />

their respective derived amplitudes and<br />

pattern.<br />

In the early phases, the excitation<br />

areas in the high-frequency acceleration<br />

spectrum (greater than 10 kHz) are rather<br />

broad. This is because structure-borne<br />

sound signals only become more apparent<br />

with declines in raceway quality.<br />

In stages where roller bearings are still<br />

discreet, the generated pulsed shock excitations<br />

with bearing-specific ball pass<br />

frequencies stem from the: external race,<br />

inner race, rolling element, and the cage.<br />

However, because the envelope method<br />

is particularly sensitive to damage it<br />

proves effective in early-stage detection<br />

by sensing amplitude changes. In the later<br />

stage, these mechanical damages can<br />

be understood through frequency deviations.<br />

Once a bearing’s defect frequencies<br />

are discovered, the defect’s location<br />

can be pinpointed. In addition, highly<br />

dynamic time signal of the acceleration<br />

offers added security in the diagnostics<br />

process. This occurs because the characteristics<br />

of rolling kinematics often are<br />

reflected within the roller bearing.<br />

Table 1 provides an overview of additional<br />

criteria for the damage diagnosis<br />

of roller bearings according to VDI 3832.<br />

Note that though diagnostic experts<br />

trust the VDI 3832, it proves to be one<br />

of the most time-consuming diagnosis<br />

models. When employing continuous<br />

roller bearing monitoring, it is more<br />

efficient to process measured time signals<br />

into scalar overall readings and to<br />

engage in deeper diagnostics only when<br />

experiencing substantial changes in the<br />

overall trends.<br />

Data-driven methods for roller<br />

bearing condition diagnosis<br />

As a result of growing trends towards<br />

predictive maintenance models, more<br />

and more data-driven analysis methods<br />

are being brought to light. (see Figure 3).<br />

It is crucial to these “big data” methods<br />

to collect the most comprehensive data<br />

volumes, enabling the extraction of characteristics<br />

using data mining methods.<br />

Ultimately, this model leverages event<br />

probability to predict future mechanical<br />

failure. The challenges of this application<br />

are (1) mastering large volumes of<br />

data, (2) understanding complex analysis<br />

processes, and (3) generating transparent<br />

forecasts. Therefore, this model has<br />

not yet become prevalent in roller bearing<br />

condition diagnostics in the wind<br />

industry.<br />

With that being said, “Smart data”<br />

applications aim to extract useful characteristics<br />

from large data volumes<br />

using often similar analysis methods,<br />

which users can understand and use as<br />

a starting point for additional analyses.<br />

There are statistical methods for extracting<br />

characteristics, which transfer<br />

overall reading trends from the time<br />

domain into the frequency domain. Ultimately,<br />

determining the representative<br />

parameters from this information.<br />

This statistical processing model offers<br />

a high level of added value for wind turbines<br />

with highly transient operating<br />

behaviour.<br />

However, in order to implement<br />

a large-scale cost-effecting system<br />

to monitor roller bearings, it makes<br />

sense to prioritize the characteristics<br />

extracted as an irregularity. This can<br />

be done by prioritizing limited values<br />

of the DIN ISO 13373-3 (broadband<br />

overall values) or characteristics of the<br />

VDI 3832.<br />

Figure 4 depicts the sequences of<br />

data-driven condition monitoring. The<br />

CMS act as an additional data supplier<br />

for overall readings and diagnostic<br />

characteristic values. If large scales or<br />

varieties of bearings are to be monitored,<br />

the classification is followed by<br />

a weighted process that assigns predefined<br />

meanings to extracted features<br />

depending on their characteristics.<br />

These predefined weighted parameters<br />

are put in place by knowledgeable experts<br />

and experience.<br />

For this procedure to function, the<br />

CMS must quickly and synchronically<br />

collect measurements across various<br />

channels. Allowing it to issue frequencyselective<br />

and order-selective overall<br />

readings and diagnostic characteristics.<br />

An incredibly powerful online CMS is<br />

the VIBGUARD IIoT from PRUFT-<br />

ECHNIK. The VIBGUARD IIoT gains<br />

its edge in its ability to offer its users<br />

data reduction options while supporting<br />

IoT-relevant protocols, such as MQTT.<br />

vibration and diagnostic priorities in the<br />

FIRST GEN’S wholly owned First NatGas<br />

Power Corp. (FNPC) owns the 414-megawatt-rated<br />

San Gabriel natural gas power<br />

Siemens APM for Power<br />

Plants is solving the<br />

data problem, pulling<br />

information together<br />

to analyze it and make<br />

it understandable<br />

so operators and<br />

maintenance can make<br />

timely and accurate<br />

decisions.<br />

other critical equipment and plant assets.<br />

Prior to the development of APM,<br />

Siemens used human interpretation<br />

of maintenance and condition data as<br />

the main mechanism to determine the<br />

health of most components in the plant.<br />

APM for Power Plants fundamentally<br />

changed that dynamic by automating<br />

the process, interpreting condition<br />

data, trending patterns and finding<br />

abnormalities, and then comparing<br />

results against the predictive models<br />

in real-time. The system analyzes asset<br />

performance history and uses advanced<br />

analytical models to detect patterns or<br />

behaviors to predict equipment failure,<br />

visualizing real-time operating and<br />

condition data to make faster and more<br />

informed decisions.<br />

The joint Bentley-Siemens solution<br />

automates the process of proactive daily<br />

inspections and maintenance, prioritizing<br />

work based on the current condition<br />

and risk profile of the asset. The<br />

predetermined, reliability-centered<br />

maintenance recommendations focus<br />

on the minimum work that is required<br />

to meet performance requirements.<br />

Real-time view of asset health, based<br />

on accurate condition data, facilitates<br />

timely and informed decisions and immediate<br />

action.<br />

The experience and lessons learned<br />

from this first installation are slated<br />

to be incorporated into the worldwide<br />

deployment of APM into many of the<br />

thousands of power plants powered by<br />

Siemens gas or steam turbines. The solution<br />

will be available for other OEMbased<br />

facilities as well. Since the software<br />

runs in an open, connected data<br />

environment it can be adjusted quickly<br />

and easily for the operating context of<br />

the unit. Combining the reliability program<br />

framework of Bentley’s AssetWise<br />

with the Siemens’ asset models, the<br />

team can optimally schedule planned<br />

outages and reduce the duration of unplanned<br />

outage events.<br />

– We take seriously that we want<br />

reliable plants, and implementing APM<br />

is our strategy for the future, said Jan<br />

Janssen, head of asset management in<br />

operations and maintenance, with Siemens<br />

ASSET MANAGEMENT<br />

Machine learning is not<br />

the gold-plated silver-bullet solution to<br />

operational woes you may think<br />

There is a lot of hope and hype associated with<br />

machine learning, data analytics, and the IIoT. To<br />

understand why your business is not achieving<br />

peak potential we need to consider all the sources<br />

of waste, including the reliability of the<br />

equipment, and the reason why that<br />

waste exists.<br />

JASON TRANTER,<br />

ARP-III, CMRP,<br />

Mobius Institute<br />

EVERY DAY, decisions are taken (and<br />

opportunities missed) that ultimately<br />

result in waste, poor equipment availability,<br />

sub-par utilization, poor quality<br />

and production throughput, and<br />

ultimately, safety/environmental<br />

incidences. If you think of your plant as<br />

a person, we shoot ourselves in the left<br />

foot during the design and acquisition<br />

phase, and in the right foot during the<br />

maintenance phase. We operate in silos,<br />

so the left hand does know what the<br />

right hand is doing, and we thus make<br />

poor decisions. The brain does not know<br />

where the<br />

opportunities exist, and the heart does<br />

not really care. The result; we limp<br />

along in frustration.<br />

We could replace the brain with the<br />

latest intelligent software, thus making<br />

better operational decisions. But<br />

ultimately all we can do is optimize our<br />

limping, uncoordinated, largely uncaring<br />

body that continues to make many of the<br />

same mistakes.<br />

So, what is the answer?<br />

We need an approach that resolves the<br />

root cause of all these issues. At the heart<br />

is the leadership and culture of everyone<br />

from the senior executive to the operator<br />

and maintainer. With a focus on business<br />

performance, and a culture of mutual<br />

benefit and contribution, everything is<br />

possible.<br />

Crystal clear understanding<br />

of our goals<br />

We must start with a clear focus on<br />

what the business is trying to achieve.<br />

Every future action must be aligned<br />

with those goals.<br />

Assess the business case<br />

Next, we must assess the current and<br />

desired state whilst recognizing<br />

where we have existing strengths, and<br />

converse ly, opportunities for improvement.<br />

It is that gap that forms the<br />

business case for this initiative.<br />

Fix the heart<br />

After developing a strategy that is aligned<br />

with those goals, we must begin the<br />

process of changing the culture. People<br />

make decisions every day that affect the<br />

costs, efficiency, and performance of the<br />

organization. They need the desire, skills,<br />

and mandate to change their behaviours.<br />

mance; we must prioritize reliability,<br />

operability, maintainability, and safety<br />

over the up-front cost. And we need a<br />

gatekeeper to keep problems out of the<br />

plant.<br />

Stop shooting ourselves<br />

in the right foot<br />

We must develop a disciplined approach<br />

to everything we do. All maintenance tasks<br />

must be performed as if lives depend on it.<br />

Just one way to do everything.<br />

Care for the equipment<br />

Our precious assets must be started,<br />

operated, maintained, and shut-down<br />

so as cause minimal stress, whilst also<br />

achieving peak output.<br />

Data driven decisions<br />

Now we apply data-driven intelligence to<br />

our process. By monitoring asset health,<br />

process performance, and key operational<br />

metrics, we can optimize our maintenance<br />

and operational decisions and eliminate<br />

waste. Continual operational improvement<br />

enables continual performance<br />

improvement.<br />

AT THE HEART IS<br />

THE LEADERSHIP<br />

AND CULTURE OF<br />

EVERYONE FROM THE<br />

SENIOR EXECUTIVE TO<br />

THE OPERATOR AND<br />

MAINTAINER.<br />

Leadership, value, and culture<br />

And now we circle back around to the<br />

core element that makes or breaks our<br />

process. With a constant focus on mutual<br />

benefit, peak performance will be<br />

sustained. If not, you will be back to the<br />

limping, uncoordinated, uncaring plant<br />

you have right now…<br />

Much more can be said about the<br />

proposed approach, but the key is to<br />

broaden your scope. Data intelligence<br />

will enable optimal performance, but<br />

only if the other elements are also<br />

addressed.

Using Ultrasound to Enhance<br />

Energy Efficiency<br />

Text: Christopher Hallum,<br />

Regional Manager, UK & Ireland,<br />

uesystems.com<br />

One of today’s greatest challenges for maintenance & reliability teams is to improve<br />

energy efficiency - high energy prices and global competition dictate a need to<br />

reduce energy waste and improve system efficiencies whenever possible. A major<br />

contributor to energy waste is leaks --both in compressed air systems and steam<br />

traps. Ultrasound inspection instruments can easily detect these leaks, leading to<br />

potential energy savings.<br />

18 maintworld 4/<strong>2019</strong>


PARTNER ARTICLE<br />

CONTRARY to what some might think,<br />

compressed air is not free. In fact, it is<br />

estimated that more than 50 percent of<br />

all compressed air systems have energy<br />

efficiency problems that should be corrected.<br />

These losses can be quite costly.<br />

Around 30 percent of all industrial compressed<br />

air is usually lost to leaks, resulting<br />

in huge losses. A leak that is just 1mm<br />

can cost a plant upwards of €1500 per<br />

year if it goes undetected.<br />

Ultrasound instruments detect<br />

the turbulent flow produced as the<br />

compressed air moves from the highpressure<br />

side to the low-pressure side<br />

of a leak. Using the characteristics of<br />

Ultrasound, locating leaks is fast and<br />

easy because of:<br />

• Directionality of sound waves<br />

makes locating the source easy<br />

• Intensity of signal: the closer<br />

you get, the more sound you<br />

detect<br />

• Fixed frequency, making it effective<br />

to locate even in a loud<br />

factory environment<br />

Using an ultrasound inspection<br />

instrument, one can implement an air<br />

leak detection survey. Compressed<br />

air leaks are bound to crop up at some<br />

point, but by having a system in place<br />

that is designed to identify them before<br />

they become a large problem, you can<br />

save time, money and energy.<br />

traps can increase operating expenses by<br />

as much as 33%. For this reason, energy<br />

conservation programs should start with<br />

a steam trap survey. Even the smallest<br />

steam trap leak can cost up to €7000 per<br />

year.<br />

Testing steam traps with ultrasound<br />

is a structure-borne or contact application.<br />

Physical contact between<br />

the steam trap and the ultrasound<br />

instrument is necessary, to “hear”<br />

how the steam trap is performing. If<br />

made, adjust the sensitivity/volume on<br />

the instrument until the sound of the<br />

trap can be heard.<br />

Reporting Steam Trap<br />

Inspections<br />

Findings from a steam trap survey<br />

can also be documented with UE Systems<br />

Ultratrend DMS software, or the<br />

SteamTrap Survey app for mobile devices.<br />

The report will outline the potential<br />

economic loses due to the faulty steam<br />

ONE OF TODAY’S GREATEST CHALLENGES FOR MAINTENANCE<br />

& RELIABILITY TEAMS IS TO IMPROVE ENERGY EFFICIENCY.<br />

Reporting & Documenting<br />

Compressed Air Leak Surveys<br />

Besides repairing the leaks, the success<br />

of the survey largely relies on proper<br />

reporting and documentation. Reports<br />

can be created easily using software like<br />

Ultratrend DMS from UE Systems, or a<br />

mobile app as the LeakSurvey app. The<br />

cost of the compressed air leaks is based<br />

on the decibel level once the leak has been<br />

located; the cost per kilowatt hour of electricity;<br />

and the pressure at the leak site.<br />

Several independent studies compared an<br />

ultrasound leak survey report with the actual<br />

energy savings, and it has been found<br />

that an ultrasound leak survey is within<br />

20% of the actual savings - when done correctly,<br />

an ultrasound compressed air leak<br />

survey can have tremendous payback in a<br />

short period of time.<br />

Inspecting Steam Traps with<br />

Ultrasound<br />

Steam leaks are also among the most<br />

wasteful, and therefore, expensive issues<br />

found in a plant. In fact, leaking steam<br />

using an ultrasound instrument that<br />

has frequency tuning, adjust the frequency<br />

to the recommending setting of<br />

25kHz. Regardless of the type of trap,<br />

the placement of the contact probe or<br />

stethoscope module attachment on the<br />

ultrasound instrument will always be at<br />

the discharge orifice of the trap. Turbulence<br />

is created on the outlet side of the<br />

steam trap when it releases condensate.<br />

Therefore, placement of the contact<br />

probe will always be at the discharge<br />

orifice side. Once contact has been<br />

traps. In order to generate a Steam Loss<br />

Report, the inspector will need to know<br />

the following information for each steam<br />

trap: Type of Trap, Orifice Size, Inlet<br />

Temperature, Outlet Temperature, Operating<br />

Condition (OK, Leaking, Blowing,<br />

Plugged, Not In Service), and how<br />

much it is costing to generate 1000 lbs.<br />

of steam. If you are using UE Systems’<br />

Ultraprobe 10000 or Ultraprobe 15000<br />

instruments, you can enter this information<br />

onboard the instrument as the<br />

steam trap survey is taking place.<br />

INDUSTRY EVENT<br />

Asset Performance 4.0:<br />

New Technologies<br />

Bring New Solutions<br />

Maintenance is teamwork - always and everywhere – and because of this, Bemas<br />

no longer considered it opportune to honour a single maintenance manager. That is<br />

why the emphasis this year was on ‘projects’.<br />

THE BRAND NEW ‘Asset Performance Awards’ were awarded to<br />

interesting maintenance initiatives in three categories. It is no<br />

surprise that ‘4.0’ was an important topic. After all, the global<br />

evolution towards digitisation, Industry 4.0 and new technologies<br />

open the doors to solutions that the maintenance world<br />

has never thought possible. –<br />

ArcelorMittal took home the Asset Performance 4.0 Award.<br />

We embraced technological evolution from the outset, says<br />

Andy Roegis, manager of industrial digitalization. The potential<br />

for production as well as quality, maintenance and logistics<br />

became clear fairly quickly.<br />

Certainly, for our division, numerous new possibilities are<br />

opening that allow us to carry out maintenance in a more focused<br />

and efficient way, maintenance engineer Pieter Van den<br />

Branden continues.<br />

The achilles heel of production<br />

At ArcelorMittal, the digital transformation revolves around,<br />

among other things, increasing production reliability. The top<br />

priority was the hot strip mill in the Ghent plant, a machine<br />

that fulfils a crucial role.<br />

It rolls slabs of steel of 23 cm to slabs of 1.5 mm thickness,<br />

which are then transported to the rewinding zone via a conveyor<br />

belt. There they are wound up into steel coils, says Pieter<br />

Van den Branden.<br />

Unfortunately, the hot strip mill is the Achilles heel of the<br />

production. This sub-installation has 340 AC motors, each of<br />

which controls a transport roller. And that’s where things often<br />

go wrong: failures in the motor or the universal joint regularly<br />

cause an unforeseen machine standstill. This causes the entire<br />

production to come to a standstill. In addition, the plates are<br />

often scratched and have passed over a defective transport<br />

roller. In short, there is both a downtime and a quality cost!<br />

Bringing together data sources<br />

A logical answer to this problem was predictive maintenance. Yet<br />

for years it proved impossible to put this idea into practice.<br />

Ordinary periodic vibration measurements did not provide<br />

enough data to define specific maintenance actions. In the<br />

end, we resorted to current and voltage measurements. In addition,<br />

we opened up the digitisation register further with the<br />

intelligent (self-learning) SAM4 software from SemioticLabs.<br />

This solution detects anomalies and generates warnings, even<br />

weeks before the breakdown will occur. And our efforts are<br />

paying off, because in the meantime the availability of the<br />

roller has increased considerably, said Andy Roegis.<br />

It is important to note that all monitoring systems are integrated,<br />

Pieter Van den Branden continues.<br />

The data from the ERP system are used to optimise the<br />

planning of the maintenance teams. Conversely, the SAM4<br />

software returns all data from monitoring and maintenance to<br />

the ERP system. This is not so much about big data, but rather<br />

about bringing together different data sources. In order to gain<br />

additional knowledge to plan maintenance even better, he adds<br />

Unseen opportunities<br />

For Infrabel, the manager of the Belgian railway infrastructure<br />

who also competed for the Award, Industry 4.0 is a strategic<br />

necessity.<br />

Although we are very active on the labour market, we have<br />

been faced with a shrinking workforce for several years now,<br />

project manager Sandrine Rauwoens states.<br />

The influx of technically trained people is too small to cope<br />

JOIN THE ASSET PERFORMANCE 4.0<br />

CONFERENCE & EXHIBITION<br />

The Asset Performance 4.0 Conference & Exhibition<br />

offers a unique opportunity to learn how new 4.0<br />

technologies and fundamentals in operations, maintenance<br />

and asset management reinforce each other<br />

to achieve higher equipment reliability and cost performance.<br />

Do you have a project that will inspire your colleagues?<br />

Or do you want to share first-hand experiences<br />

with disruptive technologies? Let us know<br />

your presentation idea on www.assetperformance.eu.<br />

with the outflow of pensionable employees. The message is<br />

therefore to work more efficiently. And digitisation is one<br />

of the ways to achieve this. In addition, we naturally want to<br />

keep up with the changes in society. New technologies, such<br />

as artificial intelligence and IOT, will determine the future.<br />

This also applies to the railways, and therefore also to Infrabel,<br />

which is responsible for the maintenance, renewal and<br />

expansion of the infrastructure. However, we are happy to<br />

go down this road. In the field of maintenance in particular,<br />

unprecedented opportunities are opening up. Measuring is<br />

knowing. Digitisation and new technologies allow for better<br />

planning and more efficient execution.<br />

Faster and safer<br />

A good example of this can be found in the ‘Prodigis’ project.<br />

In short, it concerns an optimisation process to secure<br />

the tracks for maintenance work.<br />

This is a complex and highly regulated process, Sandrine<br />

Rauwoens explains.<br />

Several procedures must be followed, each with different<br />

parties. The procedures vary according to the location<br />

and the work to be carried out. Until ‘Prodigis’, everything<br />

was done with paper forms and telephone communication,<br />

so that securing the tracks could take up to several hours.<br />

Prodigis’ is a textbook example of digitisation. We replaced<br />

a 100 percent paper-driven process with a 100 percent<br />

digital process in which process optimisation and userfriendliness<br />

are the main idea. Because the administrative<br />

part has been completely removed, we save a lot of time and


INDUSTRY EVENT<br />

the error rate is zero. This also benefits the safety of railway<br />

employees. Although ‘Prodigis’ is only a pilot, the end users are<br />

already very enthusiastic. They were also closely involved in<br />

the realisation of this digitisation project. Now a few extra procedures<br />

need to be added, after which we will roll out ‘Prodigis’<br />

geographically throughout Belgium from next year.<br />

Added value for clients<br />

SPG Dry Cooling was also one of the competitors for the<br />

award. This engineering company is known for its Air-Cooled<br />

Condensers (ACCs), which are used worldwide in power stations<br />

with a power cycle.<br />

As an innovative leader, it is our job to help customers optimize<br />

their systems, aftermarket manager Frederic Anthone<br />

says.<br />

In doing so, we aim for maximum performance of the ACCs<br />

in particular. After all, optimal capacity utilisation has a tremendously<br />

positive impact on the electrical output and the<br />

overall performance of the assets. However, ACCs do not always<br />

perform in the same way because they react quite strongly<br />

to the specific circumstances of the moment. Wind direction<br />

and speed, ambient temperature, cleanliness of the heat<br />

exchange surface, ... influence the operation. Throughout the<br />

total lifecycle many fluctuations occur, so many power plant<br />

users and operators have no idea what the maximum performance<br />

of the ACC’s actually is. In order to solve this problem,<br />

we needed a technique that could process gigantic amounts of<br />

information using advanced analytics tools. This made it possible<br />

to determine patterns and relationships in data, both in<br />

steady axis and in transient operation.<br />

Increased operational reliability and efficiency<br />

With the surge of IoT and machine learning, SPG Dry Cooling<br />

realised what seemed impossible before.<br />

We built a dedicated IoT ecosystem that provides actionable<br />

insights to the power plant operators about the performance<br />

of the steam cycle, innovation and technology manager Christophe<br />

Deleplanque explains.<br />

The ACC360 combines the thermo-physical modelling with<br />

advanced analytics. With the processed information, clients<br />

can now optimize the net electrical output and net plant heat<br />

rate. Above that they can forecast accurately the electrical output<br />

based on the actual asset condition. With this project we<br />

bridge the gap between operational performance and reliability,<br />

which allows us to provide the customer with a total asset<br />

management tool.<br />

Thanks to the use of advanced analytics and machine learning,<br />

we can develop a specific digital twin for each installed<br />

asset. This is a virtual representation of a physical product or<br />

process, used to understand and predict the physical counterpart’s<br />

performance characteristics. With this solution, we<br />

offer our customers real added value: we guarantee a better<br />

operational reliability and an optimisation of the return on<br />

investment. This gives us an excellent example of how rapidly<br />

evolving technology formulates answers to challenges that<br />

previously seemed unsolvable, Frederic Anthone concludes.<br />

Why Lubricate?<br />

It seems a simple question, yet when<br />

asked, the answers are not always similar,<br />

or simple.<br />

Some say, “to fight friction” and that<br />

is true. We do add grease to an asset’s<br />

moving parts to reduce friction. But<br />

there’s more to it than that.<br />

Some say, “to reduce heat” and that is<br />

also true. The right amount of lubricant<br />

does help keep moving parts from getting<br />

too hot. But some lube techs, thinking<br />

more is better, take it to the extreme.<br />

They add more grease -- thinking they<br />

are doing good -- and instead choke the<br />

machine’s ability to disperse heat.<br />

The real reason to lubricate assets is to<br />

form separation between surfaces. This<br />

logic applies to not only motor bearings.<br />

The pistons in an engine, chains on a chain<br />

drive, gears in a reducer, even linear bearings<br />

that do not rotate, but slide back and<br />

forth. The primary purpose to lubricate<br />

physical assets is to keep moving surfaces<br />

from coming into contact with each other.<br />

Because when they do, failure modes are<br />

initiated, and lifecycle is shortened.<br />

Friction is a force which opposes<br />

movement between surfaces. Friction<br />

increases wear between surfaces, increases<br />

system temperature, and dramatically<br />

increases power consumption.<br />

The right amount, and type of lubricant<br />

creates a thin film between two surfaces.<br />

For as long as that film is maintained, it<br />

protects the asset from wear and heat<br />

while allowing it to produce in an energy<br />

efficient way.<br />

Some lubricants offer the additional<br />

benefit of controlling corrosion. They<br />

contain additives which prevent rust<br />

from acid and water attacks.<br />

Grease must be kept free of contaminants,<br />

but the very nature of the thickener<br />

allows it to pick up dust and grit.<br />

Proper storage is therefore crucial, and<br />

clean grease applied properly can actually<br />

shield machines from the ingress of<br />

contaminants.<br />

The science of lubrication continues<br />

to evolve for over 4000 years. But the<br />

principles remain the same; to maintain<br />

separation of two or more surfaces, thus<br />

prolonging the reliability of the entire<br />

asset.<br />

What is Grease?<br />

Tremendous science goes into engineering<br />

the many grease formulations that<br />

keep physical assets working their best.<br />

The sheer number of grease types<br />

available is as varied as the applications<br />

where they are used. Yet their composition<br />

remains a simple mixture of base<br />

oil, thickener, and in most cases some<br />

additives.<br />

The Base Oil is the key ingredient of<br />

grease. Its job is to form the thin, hydrodynamic<br />

film that separates metal<br />

components from one another. When<br />

functional separation between elements<br />

is maintained, the bearing has what we<br />

term a functional grease mechanism.<br />

Base oil is the key ingredient when<br />

matching grease types to specific applications.<br />

Thickeners are the matrix of the<br />

grease. Base oil cannot resist gravity<br />

on its own. It relies on the thickener to<br />

hold it in place. The thickener makes<br />

grease effective regardless of a machine’s<br />

orientation. For instance, in a vertically<br />

oriented shaft, the base oil would seep<br />

away from the bearing making a sustainable,<br />

functional grease mechanism<br />

improbably. In addition to keeping base<br />

oil where it’s needed, thickener has the<br />

added benefit of shielding the base oil<br />

from particle contaminants.<br />

Additives are a double-edged sword.<br />

On the positive side, they enhance the<br />

lubricating properties of the base oil. Additives<br />

increase the lubricity of the base<br />

They help fight oxidation, corrosion, and<br />

extreme pressure conditions.<br />

On the negative side, they are a consumable.<br />

They deteriorate over time, so<br />

their effectiveness is not linear for the<br />

life of the grease. Additives can also have<br />

adverse effects on the thickener.<br />

Additives add an unknown function<br />

to the mad science of calculating timebased<br />

grease replenishment intervals.<br />

Most departments working on calendarbased<br />

lubrication don’t factor additives<br />

into the equation, further compounding<br />

their errors.<br />

While considerable science goes into<br />

formulating grease types, what the lube<br />

technician needs to know is that the<br />

actually reaches its intended destination<br />

and works to form an effective greasing<br />

mechanism.<br />

Greasing Myths<br />

Once you understand how grease actually<br />

works to lubricate a bearing, it becomes<br />

obvious why over-greasing causes<br />

so much trauma to both bearings and the<br />

grease itself.<br />

Remember, all we want from our lubricant<br />

is to provide a little separation<br />

in the war zone. Nothing more… nothing<br />

less.<br />

If you’re reading the term “war zone”<br />

for the first time, we use that term to describe<br />

the region of the bearing where all<br />

the wear and tear occurs.<br />

Now let’s dispel three myths about<br />

greasing bearings.<br />

Myth #1: if some grease is good, then<br />

a lot more must be great.<br />

WRONG! Most bearing manufacturers<br />

like SKF, FAG, NTN, KOYO, all recommend<br />

that the bearing housing cavity<br />

only be filled to 30% capacity. Lube<br />

departments using a time-based approach<br />

to grease replenishment almost<br />

always leave their assets in an overgreased<br />

state.<br />

ONCE YOU UNDERSTAND HOW GREASE ACTUALLY WORKS<br />

TO LUBRICATE A BEARING, IT BECOMES OBVIOUS WHY<br />

OVER-GREASING CAUSES SO MUCH TRAUMA.<br />

Myth #2: More grease will provide<br />

better cooling for the bearing.<br />

WRONG! Grease doesn’t provide cooling,<br />

air space does. Filling every void with<br />

grease chokes the bearing’s ability to dissipate<br />

heat generated by even normal friction<br />

levels.<br />

Myth #3: If there is a grease nipple<br />

on the bearing housing it must be<br />

greased.<br />

WRONG! Some motors come with<br />

“sealed-for-life” bearings installed. These<br />

are meant to be never greased… EVER.<br />

Yet someone thought it would be clever<br />

to install a grease nipple anyways. You<br />

have to know what’s inside your motor<br />

because grease is like tooth paste. Once<br />

you squeeze the trigger you can’t stuff the<br />

grease back inside the tube.<br />

Enough bad practices please. We need<br />

a greasing strategy, but more than this, we<br />

need a greasing culture. Bad greasing culture<br />

eats good greasing strategy for lunch.<br />

It only takes one bad actor, often wellintentioned<br />

– to destroy an asset.<br />

Grease guns don’t kill bearings… people do.<br />

How Grease Works<br />

We know bearings need grease; both to<br />

perform well and to last a lifetime. But do<br />

we really understand where that grease<br />

goes and how it performs its function?<br />

There are two states that grease lives<br />

in when a bearing is lubricated. We refer<br />

to them as the Bleeding Phase, and the<br />

Churning Phase. Let’s review so we can<br />

better visualize what’s happening in each<br />

phase.<br />

Remember that grease is made up of<br />

oil, thickener and additives. The thickener<br />

is the vehicle which delivers base oil to the<br />

war zone, where the rolling elements meet<br />

the races. These contacts points are kept<br />

4/<strong>2019</strong> maintworld 27


PARTNER ARTICLE<br />

separated by the oil film that lubricates<br />

the contact point interface. There are<br />

two distinct phases or conditions that<br />

can exist.<br />

The Churning Phase describes the<br />

phase or condition when thickener is<br />

present within the war zone.<br />

The Bleeding Phase describes the<br />

phase when only the base oil is present<br />

in the war zone.<br />

Let’s concentrate first on the churning<br />

phase. When there is thickener in<br />

the raceway, higher friction levels are<br />

present. The rolling elements must<br />

“plough” their way through this media.<br />

The result is higher temperatures from<br />

the bearing, and ultimately the motor.<br />

The motor consumes more electricity<br />

and the excess heat accelerates lubricant<br />

deterioration and consumption of additives.<br />

When we over grease a bearing we<br />

cram thickener into the war zone; and<br />

we force that thickener to stay in the war<br />

zone. And that is a huge problem. It’s<br />

stuck there. That means the thickener<br />

sits there and get run over by the rolling<br />

elements millions of times a day.<br />

Two significant problems come from<br />

this:<br />

1. The fibers of the thickener get<br />

crushed to the point where it can no<br />

longer hold the base oil where it’s<br />

needed. The grease ages prematurely,<br />

adding more inaccuracy to your timebased<br />

re-greasing regimen.<br />

2. The fibers of the thickener, now<br />

crushed to smaller sizes, become suspended<br />

in the base oil. This changes<br />

the lubricant’s viscosity to the extent<br />

that it no longer matches the required<br />

lubricity of the application.<br />

By crushing the thickener in the churning<br />

phase we’ve completely altered the<br />

properties of the lubricant and dramatically<br />

reduced its lifespan.<br />

It is quite normal for the bearing and<br />

grease to be in the churning phase for a<br />

few seconds. This happens during grease<br />

replenishment, with each injection of<br />

new grease. The time for new grease to<br />

enter the bearing and settle to the grease<br />

cavity is called a stabilization period. Depending<br />

on the RPM of the bearing, this<br />

can be a few seconds or several minutes.<br />

What lube techs must know is that<br />

their job is to transition the bearing from<br />

the churning phase to the bleeding phase<br />

as quickly as possible. This happens when<br />

a planned strategy for re-lubrication is in<br />

place, and they don’t exceed the calculated<br />

grease replenishment quantity.<br />

The bleeding phase describes the<br />

optimum condition where the right<br />

amount of grease resides outside the war<br />

zone, and the movement of the bearing<br />

allows only the base oil, infused with<br />

additives, to sufficiently bleed from the<br />

thickener to the space between the rolling<br />

elements.<br />

The only way to confidently know the<br />

bearing has reached an optimal churning<br />

phase is to measure its friction levels<br />

with an ultrasound instrument accurate<br />

enough to deliver repeatable, reliable<br />

data.<br />

Time-based vs Conditionbased<br />

lubrication<br />

Until now industry was content to satisfy<br />

their asset’s lubrication needs based on a<br />

calendar and a calculator.<br />

“Add this many shots after this many<br />

hours in service” instructs the motor<br />

plate. And away went the lube tech,<br />

blindfolded, grease gun in hand, oblivious<br />

to the destructive potential of his<br />

actions. Don’t blame him. He’s doing his<br />

job the best way he can.<br />

The problem is not the lube tech, it’s<br />

the philosophy that gave birth to his bad<br />

practices and the less than excellent culture<br />

that allows them to continue.<br />

Why complicate lubrication with<br />

calculators designed to estimate<br />

grease replenishment quantities, and<br />

calendars designed to estimate grease<br />

replenishment intervals? Especially<br />

when these calculations return invalid<br />

answers that destroy assets and profits.<br />

Let’s review what Goldilocks discovered.<br />

• Add too much grease, and bearings<br />

enter a churning phase that produces<br />

high friction.<br />

• Add too little grease, and there’s no<br />

separation of components, also producing<br />

high friction.<br />

• Add just the right amount, and bearings<br />

enter the bleeding phase where<br />

friction levels are low.<br />

The common denominator in these<br />

three scenarios is FRICTION.<br />

And we now know that the best technology<br />

to monitor, measure, and trend<br />

friction is ultrasound.<br />

Training cannot overcome poor, or<br />

lack of tools. Good procedures are not<br />

enough. Lube technicians need the right<br />

tools, and they need to be trained on how<br />

those tools interact with their organization’s<br />

goal to achieve precision lubrication.<br />

Yesterday, the best they might have<br />

had is a calendar and a calculator. Are<br />

these the best tools to achieve precision<br />

lubrication? They might have been at<br />

one time. This might even have passed<br />

for leading edge thinking. But it wasn’t<br />

right then, and its surely wrong today.<br />

When a trained lube tech measures<br />

the effect every shot of grease has<br />

on the friction levels in a bearing, he<br />

knows when to start, when to stop,<br />

and exactly what quantity of grease is<br />

required to restore optimum friction.<br />

When a trained lube tech achieves<br />

lubrication excellence, he becomes a<br />

LUBExpert.<br />

IN NOVEMBER 2015, we described not<br />

only the DREAM: “It would be ideal,<br />

however, if all devices and services were<br />

able to communicate independently<br />

with one another, irrespective of the<br />

manufacturer, the operating system, the<br />

hierarchy and the topology. The offered<br />

functionality of devices should be readable<br />

– but not for everyone. That requires<br />

security functions with authentication<br />

and encryption directly in the device. In<br />

case of failure of the data link the data<br />

should not be lost, but automatically<br />

buffered for a while.“<br />

We also gave you insides of the<br />

reality. As long as hard real-time requirements<br />

are not concerned today, this demanded<br />

interoperability can already be<br />

achieved today with the assistance of the<br />

OPC Unified Architecture (OPC UA).<br />

In 2015, we also predicted the Future<br />

with the initiative started by KUKA<br />

about evaluating and implementing<br />

the usage of IEEE 802.1 Time Sensitive<br />

Network (TSN) technologies as an additional<br />

underlaying IT infrastructure<br />

enabling OPC UA for deterministic data<br />

transfer.<br />

In 2017, we predicted the “Trend:<br />

Information models” to save money<br />

when we asked the question “OPC UA<br />

provides secure transport of data via diverse<br />

and expandable protocols. But who<br />

defines the data’s meaning? We reported<br />

about the start of the robotics standardization<br />

group and their efforts to<br />

standardize semantic now, agreeing on<br />

the same interfaces for data and services<br />

based on OPC UA!<br />

Let’s see the results from the<br />

<strong>2019</strong> perspective:<br />

Status: Information models<br />

• The robotics group under the roof of<br />

VDMA has published the “OPC UA<br />

for Robotics Companion Spec” agreeing<br />

on data and interfaces including<br />

their meaning and behaviour. For the<br />

Microsoft Azure dashboard, it was<br />

easy to integrate live data from robot<br />

companies like ABB, Beckhoff, KUKA,<br />

Siemens, Engel, KEBA, Mitsubishi<br />

Electric Kraus Maffei and Yaskawa as<br />

all of them provided semantic identical<br />

data and interfaces.<br />

• AutoID devises from Balluff, Harting,<br />

Leuze, Sick, Siemens and Turck have<br />

been available already for a while –<br />

their vendor association “AIM” standardized<br />

again data and interfaces for<br />

AutoID devices: Even the devices<br />

offer different signal types like 1D, 2D,<br />

HF- or UHF-RFID, OCR or RTLS they<br />

offer one set of interfaces and data to<br />

communicate with all of them! A huge<br />

reduction in costs!<br />

• Multiple more groups have finalized<br />

their work: “MDIS” in the world of<br />

Oil&Gas but also “MachineVision” for<br />

intelligent cameras or “EuroMAP” for<br />

Plastics and Rubber machinery.<br />

ASSET MANAGEMENT<br />

Part I<br />

Leaders in<br />

Maintenance<br />

TORBJÖRN<br />

IDHAMMAR ,<br />

President of IDCON<br />

Mahatma Gandhi was<br />

once asked what he<br />

thought of Western civilization.<br />

He replied that<br />

he thought it would be<br />

a good idea. The same<br />

thought comes to mind<br />

when considering management<br />

skills in maintenance<br />

departments.<br />

MAINTENANCE PERSONNEL often become<br />

leaders by a touch of “the magic<br />

wand.” The wand works in a mysterious<br />

way. The wand magically transforms<br />

a person who has never held<br />

a leadership position into a leader.<br />

It converts the person into a leader<br />

seamlessly without any training,<br />

coaching, job description or direction<br />

from peers. Its use usually takes place<br />

around 5:30 p.m. on Fridays and magically<br />

(hence the name) transforms the<br />

person into a maintenance leader by<br />

6 a.m. on Monday. The wand just may<br />

be the best maintenance tool on the<br />

market!<br />

Examples of magically born leaders<br />

are young engineers taking supervisory<br />

positions, senior engineers becoming<br />

maintenance managers, craftspeople<br />

becoming maintenance planners<br />

and purchasing people becoming<br />

maintenance spare parts managers.<br />

In this article, I will share some<br />

thoughts on maintenance leadership,<br />

especially for all the people out there<br />

who have crossed paths with “the<br />

wand.”<br />

32 maintworld 4/<strong>2019</strong>


ASSET MANAGEMENT<br />

If you are a maintenance or plant<br />

manager, consider if you have set up a<br />

clearly defined “place to go” for your<br />

maintenance and reliability efforts<br />

and define best practices. IDCON does<br />

this work for many organizations and<br />

usually divides the checklist into these<br />

categories:<br />

• Maintenance leadership and organization<br />

• Preventive maintenance<br />

• Planning and scheduling<br />

• Spare parts management<br />

• Root cause problem elimination<br />

• Engineering’s interface with maintenance<br />

• Technical database<br />

• Skills improvement for hourly and<br />

management<br />

• Facilities, tools and workshops<br />

You may want to consider using this<br />

categorization as a start for your list. The<br />

idea is to make a checklist within each<br />

category that is very clear to the organization.<br />

In the PM section, you may state<br />

“we will store lubricants properly”; or, in<br />

spare parts management, “we’ll have an<br />

inventory record accuracy of 95 percent<br />

or higher.”<br />

Regardless if you are a corporate<br />

manager, plant manager, maintenance<br />

manager, planner or a supervisor, ask<br />

yourself if you have a set of beliefs to<br />

lead toward. If not, I suggest you make a<br />

list together with your organization.<br />

Suggestion No. 2: Understand<br />

the role of a maintenance<br />

leader<br />

Many people believe that the role of<br />

a maintenance leader is to tell other<br />

people what to do. I think this is wrong.<br />

Other people feel that the role of a<br />

maintenance leader is to motivate and<br />

encourage other people. I think this is<br />

somewhat misguided as well. Let me<br />

explain.<br />

The role of a maintenance leader is<br />

simply to get other people to do what<br />

you want them to do. Encouragement,<br />

motivation, group decisions and much<br />

more are tools that steer people in the<br />

right direction. But at the end of the day,<br />

a leader is trying to make other people do<br />

what he or she wants them to do. Again,<br />

if a leader is successful, we hope the<br />

company they work for has defined in<br />

simple terms, where to lead.<br />

How can maintenance leaders make<br />

people do what they want them to do? I<br />

think this is an art that few can master<br />

but that many can improve on. Let’s expand<br />

on that.<br />

To get people to do what you want<br />

them to do, you must continuously build<br />

business processes that enable them to<br />

perform at their best. As a maintenance<br />

leader, you must realize that people can<br />

never be more effective than the system<br />

they work in.<br />

In a survey of 442 maintenance lead-<br />

Graph: Survey respondents were asked, “How much time do your maintenance planners<br />

spend on actual planning of maintenance work?”<br />

Suggestion No. 1: A leader<br />

must first know what to lead<br />

toward<br />

The whole idea of being a leader falls<br />

apart if the leader does not know what<br />

beliefs to lead toward. What is the longterm<br />

purpose of reliability and maintenance<br />

management in your company,<br />

plant, area or department? Hopefully,<br />

your company has documented and<br />

disseminated beliefs for reliability and<br />

maintenance management. If not, the<br />

company, plant, area and/or department<br />

have set up its leaders to fail.<br />

ASSET MANAGEMENT<br />

ers, IDCON asked: “How much time<br />

do your maintenance planners spend<br />

actually planning maintenance work?”<br />

60 percent of the respondents stated<br />

that less than 30 percent of their planners’<br />

time is spent on planning work. 26<br />

percent said planners plan less than 10<br />

percent of the time.<br />

In a follow-up survey, we asked, “Why<br />

do planners not plan?” Given eleven<br />

THE WHOLE IDEA OF BEING<br />

A LEADER FALLS APART<br />

IF THE LEADER DOES NOT<br />

KNOW WHAT BELIEFS TO<br />

LEAD TOWARD.<br />

choices, the respondents said the top<br />

three reasons are:<br />

Too many emotional priorities (work<br />

that could wait breaks schedule).<br />

Too many “do-it-now” jobs due to<br />

equipment breakdowns.<br />

Operations do not support the planning<br />

process.<br />

In this example, leaders must help set<br />

up roles and responsibilities for planners<br />

and people involved in the planning and<br />

scheduling process and then make sure<br />

the processes are followed. They should<br />

work with operations, stores and engineering<br />

to agree on work order priority<br />

rules, schedule cut-off times, identify<br />

critical equipment and spares, and much<br />

more.<br />

The chance of getting people to do<br />

what you, as a leader, want them to do<br />

increases drastically if enablers are instituted<br />

in the plant.<br />

“Talk the talk and<br />

walk the walk”<br />

Realize that your people follow your<br />

lead. Employees do what you do, not<br />

what you tell them to do. It is critical<br />

to “walk the walk” by following up and<br />

sticking to the plans, best practices and<br />

enablers that you, as a leader, have put<br />

in place.<br />

A leader that constantly starts meetings<br />

late will have a very hard time<br />

instilling good scheduling practices in<br />

the organization. A leader cannot expect<br />

quality work order plans if he or she<br />

constantly asks for completion of unnecessary<br />

last-minute work. A leader<br />

cannot expect world-class craftsmanship<br />

if craftspeople are not trained, or if there<br />

is a lack of financial support for repairs,<br />

no time given to complete jobs, no standards<br />

or no detailed expectations.<br />

If you are a true maintenance leader,<br />

make sure that each attempt at improvement<br />

has substance behind it by producing<br />

a solid plan where cost and benefits<br />

are considered before involving the<br />

whole organization. It is very common to<br />

see a plant sign up for the project of the<br />

month only to have it replaced by a new<br />

effort a few months later.<br />

While visiting a plant a few years ago,<br />

I mentioned that reliability improvements<br />

should go on forever. It is a continuous<br />

process. A craftsperson in the<br />

audience said, “In this plant, forever is<br />

eight weeks, and the yield for reliability<br />

improvements in eight weeks will most<br />

likely be fairly small.” Not understanding<br />

quite what he meant, he further<br />

explained, “All started improvement efforts<br />

are announced to last forever. The<br />

average life of a new improvement initiative<br />

in the plant is about eight weeks.<br />

Therefore, forever in this plant means an<br />

eight-week project.”<br />

Even though the statement was<br />

meant partly as a joke, he was right on<br />

the money for this particular plant.<br />

MANAGEMENT<br />

A 12 Step Program to Stop<br />

the Reorganization Insanity!<br />

36 maintworld 4/<strong>2019</strong>


MANAGEMENT<br />

How many reorganizations (reorgs) has your company gone through in<br />

the past five years? Some will say too many to count. It is not uncommon<br />

these days to see companies have one to three reorgs per year in various<br />

departments and even the corporation as a whole.<br />

ALAN WARMACK<br />

Energy Services<br />

Director and Partner<br />

Marshall Institute<br />

BELOW IS A 12-STEP program to assist<br />

you in improving your company’s<br />

operational effectiveness. Let’s stop the<br />

insanity and build a plan that will be successful!<br />

1. Admit you have a problem!<br />

a. Many times, we know we have problems,<br />

but we don’t start the improvement<br />

process by clearly defining them.<br />

We wind up taking a “shotgun approach”<br />

and shooting in the dark, hoping to<br />

hit the mark. This rarely works. When<br />

leadership is ready to undertake an initiative<br />

as large and impactful as a reorg,<br />

ensure that it will be one of the solutions<br />

and not become just another part of the<br />

problem.<br />

2. Understand the “true”<br />

problem and its source<br />

(Assessment)<br />

a. If you want to truly get to the bottom<br />

of your issues, you must recognize all the<br />

gaps inside your company, departments<br />

and business units, etc.<br />

b. An assessment provides a “cold<br />

eyes review” of your current situation<br />

and should be compared to industry best<br />

practices in order to build a gap analysis<br />

c. Here is where another mistake<br />

can be made if you are not careful. Assessments<br />

can be too high level. We<br />

don’t ask the Subject Matter Experts<br />

(SME). Who is that, you ask? It is the<br />

personnel that live in the poor processes<br />

currently. It’s the operators that<br />

(struggle to) run your process every<br />

day. It’s those maintenance technicians<br />

that are forced into a reactive process,<br />

so we only have time to “fix it when it<br />

breaks”. It’s their supervisors that are<br />

many times, handcuffed into working<br />

with sub-prime workflow processes<br />

and systems.<br />

d. If you want to understand the<br />

problems, you simply must ask the right<br />

people. They know what’s wrong and<br />

many times they have great ideas on how<br />

to make it better. We simply don’t ask<br />

them because “we know what needs to<br />

be done”.<br />

3. Build strategies so people<br />

can be successful<br />

a. Align to the mission of the organization<br />

– If you have done a good job of<br />

producing a successful assessment and<br />

now have a detailed gap analysis, you<br />

are on a much better path to addressing<br />

your opportunities for improvement.<br />

As part of this step, you should take the<br />

time to prioritize all the opportunities by<br />

performing a risk analysis on each item<br />

in order to properly prioritize them.<br />

Once again, mistakes can be made at this<br />

point. You take the proverbial “shotgun<br />

approach” and try to hit everything all at<br />

LET’S STOP THE INSANITY<br />

AND BUILD A PLAN THAT<br />

WILL BE SUCCESSFUL!<br />

once. We call this being “a mile wide and<br />

an inch deep.” Prioritize your list and<br />

ensure that your plan is aligned to the<br />

company’s mission. If you can ensure<br />

your plan is designed with these things<br />

in mind, your chances of improving the<br />

right things at the right time is beginning<br />

to have a chance at success.<br />

b. Design department goals and objectives<br />

that support the company mission.<br />

So, you have a high-level mission for the<br />

company. You have goals and objectives<br />

defined by Corporate leadership. We<br />

must now ensure that the plant, and or<br />

the departments being affected will use<br />

the information from the assessment<br />

gap analysis to set their own goals and<br />

objectives. In order to properly prioritize<br />

the improvement activities, they<br />

should align their plans in support of the<br />

company mission, goals and objectives.<br />

Key stakeholders should begin designing<br />

their improvement plans using a risk<br />

benefits analysis in order to assist in prioritization<br />

of activities.<br />

c. Development of Work Process<br />

flows to support daily functions of<br />

the department. One of the key activities<br />

will be design of the workflow<br />

process(es), dependent on the function<br />

of the department in the overall scheme<br />

of the plant. This should have started as<br />

part of the assessment to determine the<br />

“as is” current process, in which many<br />

opportunities are identified during this<br />

exercise. Once this is designed, reviewed<br />

and gaps clearly identified, you can then<br />

use this “brown paper” to design a “to<br />

be” process. Then a “white paper” exercise<br />

should be designed to address all of<br />

the issues identified in the current way<br />

of doing business. Once designed by the<br />

SMEs, it is best practice to have others<br />

review it, using team members from the<br />

exercise to “walk” the reviewers through<br />

the process. This begins to build buy in<br />

as now it’s their process. Getting feedback<br />

from others gives them an opportunity<br />

to contribute and hopefully gain buy<br />

in as well, making the process rollout a<br />

little less stressful. It won’t be the first<br />

time they have seen it and they helped to<br />

build it.<br />

d. R & Rs designed to support Dept<br />

processes and meet goals and objectives.<br />

Once the new process flow(s) is built, the<br />

next step will be to design a RACI chart.<br />

»»<br />

R – Who is Responsible for performing<br />

the activity?<br />

»»<br />

A – Who is Accountable for ensuring<br />

the task is completed?<br />

»»<br />

C – Who should be Consulted to<br />

ensure the task is performed properly?<br />

»»<br />

I – Who should be kept Informed<br />

on the status of the task?<br />

»»<br />

e. To start understanding the work<br />

process flow and the RACI, start at<br />

the beginning and ask:<br />

• Who is in the box?<br />

• What is their role in the box?<br />

• What level of training is required<br />

to provide adequate knowledge of<br />

the task(s) and the skills required<br />

4/<strong>2019</strong> maintworld 37


MANAGEMENT<br />

to perform them?<br />

• What level of live coaching in the<br />

field may be required to ensure<br />

they not only have knowledge, but<br />

also that their skills are adequately<br />

developed?<br />

• What work aids can be produced to<br />

ensure consistency of process?<br />

• What are auditable points that can<br />

be developed to ensure sustainability<br />

of the process step?<br />

After determining the RACI and answering<br />

the questions above, you have just<br />

provided a serious level of information<br />

needed to build the formal Roles and Responsibilities<br />

for each position!<br />

4. NOW, you can consider<br />

organizing to better<br />

support the company and<br />

departmental mission<br />

a. Once you have successfully started<br />

closing gaps and implementing the new<br />

processes as designed, you will have a<br />

much better idea of what your organization<br />

should look like, but…<br />

• Be careful not to cut and move<br />

personnel too quickly, as you may<br />

still have further changes to the<br />

process as you get things working.<br />

This could have a direct effect on<br />

what you do with personnel.<br />

• You may find that as you reduce<br />

your organization through attrition,<br />

as the improvements will<br />

not happen overnight. You make<br />

improvements this year, some personnel<br />

retire, and you determine<br />

“We don’t need to fill the position”,<br />

as you are running much more efficiently<br />

now. You can continue this<br />

process over multiple years.<br />

You are NOT finished! You’re only on<br />

Step four!<br />

5. Ensure all personnel are<br />

properly trained to the new<br />

improved processes<br />

a. Based on the bullets Step 3d & 3e, you<br />

can now design the appropriate training<br />

matrix in cooperation with Human Resources<br />

(they will be very happy that you<br />

are designing this). This will be required to<br />

ensure everyone inside the workflow process<br />

and sub-processes are appropriately<br />

trained. Included in the training matrix<br />

should not only be the process training,<br />

but all competencies and skills required to<br />

perform their work in their position daily.<br />

b. As information – World Class<br />

companies provide between 80 and 120<br />

hours of skills-based training annually. If<br />

you think you can’t afford training, how<br />

expensive is ignorance?<br />

c. Be sure and start by letting each<br />

person provide a self-assessment in order<br />

to determine what they think they<br />

are good at and where they think they<br />

need help. You must ensure they are encouraged<br />

to be honest on the assessment<br />

as this is the time to say you need more<br />

training, coaching, etc. so it can be added<br />

into your training plans. Telling us you’re<br />

great at everything will help no one. It<br />

delays training you might have received<br />

earlier if known.<br />

6. Build internal expertise to<br />

drive change, constancy of<br />

purpose and communications.<br />

a. Identify your coaches. As the new processes<br />

are designed and being prepared<br />

to be rolled out, it will be important to<br />

set up personnel in each area that have<br />

been instrumental throughout design,<br />

testing and now rollout. They will help<br />

drive performance to the new standards<br />

in each area and help make the processes<br />

sustainable.<br />

b. These positions can be full time<br />

or part-time. They need designated<br />

time for coaching as part of their daily<br />

activities. This is easier said than done,<br />

especially when you are on the front end<br />

of implementation. It takes time and<br />

commitment on the part of leadership to<br />

allow resources time to get the processes<br />

embedded. Otherwise, it will fall apart<br />

and be the next “flavor of the month”.<br />

7. As you begin to close the<br />

gaps for each dept based<br />

on assessments, find quick<br />

wins to show personnel that<br />

this new way of business<br />

can be effective, and build<br />

excitement for things to come<br />

a. Everyone is watching, in whatever you<br />

do (or don’t do). How you present new<br />

processes and systems is as important<br />

as what they are supposed to achieve.<br />

Any time you can take the ideas and<br />

suggestions from the SMEs and others<br />

and make positive, quick improvements<br />

that are visible to everyone, it will go<br />

a long way with the masses. For one, it<br />

shows you listened. It also gets people<br />

excited to see what else might improve<br />

given time. You will need these types of<br />

wins, as a lot of the improvements will<br />

be behind the scenes and take longer to<br />

implement. The trick is to keep coming<br />

up with quick wins when you can to help<br />

keep momentum over time.<br />

8. Align your systems to<br />

support the company’s and<br />

departments missions, goals<br />

and objectives<br />

a. Don’t let the system dictate how you<br />

work. Too many times we see companies<br />

buy new CMMS systems or other<br />

tools and then adjust their processes to<br />

the tools shortcomings. We don’t work<br />

the way we want or need to because the<br />

tool “won’t do that”. This should not<br />

be acceptable. If you have performed<br />

thorough due diligence before deciding<br />

on a new tool or system, you should have<br />

a very thorough design specification<br />

which will “weed out” those who cannot<br />

provide you with something that can<br />

support your processes as designed.<br />

9. Recognize that you have<br />

many of the answers to<br />

making these changes and<br />

improvements in the palm of<br />

your hand (SMEs on the floor)<br />

a. Use your Subject Matter Experts! As<br />

mentioned throughout this article, there<br />

is a group of people at all our sites that<br />

38 maintworld 4/<strong>2019</strong>


MANAGEMENT<br />

to work orders, etc. These activities<br />

are best designed through the<br />

use of pictures with short step<br />

procedures. They can depict good<br />

vs. bad conditions. They can show<br />

sequencing steps and many other<br />

things. Once again, use your SMEs<br />

to help design these plans.<br />

would love to be heard. You as a leader,<br />

do not have to have all the answers. A<br />

good leader recognizes this point and realizes<br />

that a good leader utilizes his people’s<br />

expertise to drive improvements.<br />

They have the answers if we will just<br />

listen. We simply need to provide the vision<br />

and guidance as needed. Otherwise,<br />

give them the opportunity and get out of<br />

the way.<br />

10. Embed the improvements<br />

a. Set up standards. In many cases, you<br />

have expended huge amounts of time<br />

and resources to make these improvements<br />

which will hopefully bring you to<br />

the “best in class” status. Now you need<br />

to ensure these processes get embedded.<br />

b. What happens if we still decide to<br />

reorganize? Your people now work to<br />

standardized processes. If a manager<br />

moves to a new department, it is part of<br />

our process to ensure they are properly<br />

trained on the processes for that department<br />

and their roles and responsibilities<br />

inside of those workflow processes. It<br />

is NOT their place to come in and kill<br />

all the efforts you have expended just so<br />

they can leave their mark and then move<br />

on to bigger and better things. They are<br />

welcomed to learn their place and then<br />

help us continuously improve, but not<br />

to totally disrupt all of the hard work<br />

and start all over again going down some<br />

totally different way of working. This is<br />

very demoralizing to the staff when this<br />

happens. We also have practices in place<br />

for people that change positions through<br />

promotions and other reasons. Same as<br />

the manager, they will be trained in their<br />

new position, not left to figure it out on<br />

their own.<br />

11. Sustain the improvements<br />

a. To assist in sustainment, there<br />

are many ways to use various audits<br />

throughout your processes. One way<br />

to identify these audit points is to keep<br />

them in mind when building out the<br />

white paper for the new process steps.<br />

Always ask is this a point in the process<br />

that should be audited. How will we<br />

measure and track it? Is it important<br />

to drive the process to be sustained or<br />

maybe improved?<br />

b. Set up Standards. There will be opportunities<br />

throughout the processes to<br />

institute standards on the floor.<br />

• 5S – Organize your workplace and<br />

set up standards which show how<br />

it should be maintained<br />

• Single Point Lesson Plans –<br />

Standards which can be placed<br />

on equipment, in shops, attached<br />

• Planner’s checklists – Ensure<br />

planners are as efficient and effective<br />

as possible when going to the<br />

field to walkdown job requests to<br />

determine scope. This helps standardize<br />

expectations of quality work<br />

packs across planner personnel.<br />

• Standards used on PMs - Good vs.<br />

bad condition checks. Wear conditions,<br />

Adjustment procedures.<br />

12. Celebrate!<br />

a. As you begin to perform all of the activities<br />

discussed in this article, you must<br />

remember to communicate well, and<br />

also, acknowledge key milestones, which<br />

when achieved, there is some form of<br />

congratulatory effort made dependent<br />

on the scope of the accomplishment(s).<br />

You must know your people and what<br />

“makes them tick” so you understand<br />

what these celebrations might look like.<br />

• Individual recognition – This can<br />

be very different from one person<br />

to the next. One might simply<br />

appreciate a pat on the back and<br />

“good job”, while others would<br />

appreciate group recognition,<br />

monetary, gift card, etc. Make sure<br />

you know your people to give them<br />

something that is meaningful to<br />

that person.<br />

• Group or department recognition<br />

– This can be just as tricky when<br />

determining what works on average<br />

for the whole group. It may<br />

be grilling steaks for everyone. It<br />

could be a family picnic for the<br />

department. The importance of<br />

this section is this. We tell people<br />

to do things. We should also tell<br />

them how they are doing and when<br />

they achieve the improvements we<br />

expect, show your appreciation for<br />

the hard work.<br />

EVENT<br />

The Swedish Maintenance Society<br />

Celebrated its 50th Anniversary<br />

The Swedish Maintenance Society<br />

(SvUH) hosted a two-day conference<br />

in October offering a slew of inspiring<br />

industrial maintenance-related presentations<br />

to follow as well as excellent networking<br />

opportunities. The event was<br />

organized to celebrate the society’s 50th<br />

anniversary. Text: Nina Garlo-Melkas Photo: SvUH<br />

AT THE EVENT several speakers from the business and academic<br />

worlds alike focused on how artificial intelligence (AI) is<br />

influencing maintenance operations of the future. Discussion<br />

especially centred on how the collection and analysis of massive<br />

amounts of data is transforming the ways maintenance<br />

operations are performed. Predictive maintenance (PdM) was<br />

a key theme: above all, how technological advances are increasing<br />

the possibility of predicting when it is time to perform<br />

maintenance operations.<br />

Jerry Johansson from Astra Zeneca explained in his presentation<br />

how the pharmaceutical company has tested AI in<br />

their production facility in Södertälje, Sweden. The company<br />

began by analyzing historical data collected from three machines<br />

during a period of two years. Next the company plans to<br />

start using the methodology with real-time data.<br />

– Initially, I was hesitant and thought we would only see<br />

quality deviations, but I was wrong. It worked well and it is<br />

great to see what we can do with relatively little effort. Many<br />

believe that artificial intelligence completely changes maintenance<br />

work and that it is the solution to many problems. But it<br />

is not so easy to get started and get good results.<br />

Education a key theme<br />

Education was another important theme. Philip Tretten from<br />

Sweden’s Luleå University of Technology lectured on how his<br />

employer works to train future maintenance engineers for the<br />

challenges they will face in the future. He also admitted that<br />

despite the industry’s need for highly qualified maintenance<br />

workers, finding students can be tough. This is a potential<br />

future threat that requires swift measures in order to help<br />

boost the image of maintenance professions among potential<br />

students.<br />

Project Manager Tomáš Hladík at Logio s.r.o. introduced<br />

in his presentation eight rules for effective spare parts management.<br />

These included the needs to go for preventive maintenance<br />

practices, segment your spare parts portfolio, evaluate<br />

spare parts criticality and the requirement to consider the<br />

whole life cycle of your equipment.<br />

For fifty years, The Swedish Maintenance Society has helped<br />

the Swedish industry, suppliers of products and services and<br />

academies to develop and improve maintenance, reliability and<br />

physical asset management.<br />

These things, when considered, can result in reduced carrying<br />

costs, reduced performance interruption, and improved<br />

overall efficiency.<br />

Finance and maintenance were the focus of steelmaker Ovako’s<br />

maintenance manager Charlotta Backman. What does<br />

an unplanned maintenance stop cost? It can cost huge sums<br />

that you do not necessarily see, ranging from technical inaccessibility<br />

and delayed deliveries to the worst that can happen<br />

with accidents. Ovako uses a Failure Mode and Effects Analysis<br />

(FMEA) specially focused on maintenance. With this tool they<br />

can prioritize maintenance and get a better picture of what<br />

their maintenance operations really cost.<br />

In addition to lectures, the conference also included a minifair<br />

with several exhibiting companies. The event took place at<br />

the Munich Brewery in Stockholm on 3–4 October.<br />

MARKET<br />

Why Equipment Rental<br />

Makes Long-Term<br />

Sense for Your<br />

Business and<br />

the Environment<br />

MICHEL PETITJEAN,<br />

Secretary-General of<br />

the ERA<br />

The ‘access to goods’<br />

model is key to creating<br />

a more sustainable economy<br />

– and long-term<br />

success for those who<br />

seize the opportunity.<br />

MANY FORWARD-THINKING COMPANIES<br />

are taking advantage of the huge opportunities<br />

offered by equipment rental.<br />

In fact, in the ERA Market Report <strong>2019</strong><br />

there was growth in all 15 countries covered<br />

by the report (representing more<br />

than 95 percent of the EU-28 and EFTA<br />

countries’ total rental turnover) and<br />

equipment rental companies and other<br />

companies providing rental services<br />

generated a total rental turnover of more<br />

than 26.0 billion euros.<br />

ERA, the European Rental Association,<br />

is the representative association of<br />

the equipment rental sector in Europe,<br />

where we promote the shift from the<br />

“ownership of goods” to the “access to<br />

goods”; where the industry can reduce<br />

resources and make better use of equip-<br />

ment throughout its lifecycle.<br />

By renting equipment you have access<br />

to the right product when you need<br />

it, you avoid the burden of excessive<br />

investment and maintenance and you<br />

outsource the product responsibility and<br />

legal compliance costs.<br />

But more than that, renting equipment<br />

reduces carbon emissions.<br />

Renting is fundamentally<br />

sustainable<br />

The objective of a circular economy is to<br />

maintain the value of products, materials<br />

and resources in the economy for as long<br />

as possible, while minimising the generation<br />

of waste.<br />

For us at ERA and the rental companies<br />

we represent – over 5,000 of them<br />

throughout Europe – we see sustainability<br />

not only as a way to address the significance<br />

of green issues in construction,<br />

but also to increase customer value.<br />

Increasing value comes not just<br />

through performance, but also through<br />

efficiency. Standing out from the crowd,<br />

for all the right reasons, gives them a<br />

healthy competitive edge.<br />

And renting equipment, instead of<br />

buying it outright, gives our members’<br />

customers an excellent opportunity to<br />

showcase their environmental credentials<br />

to their end customers.<br />

The ERA recently undertook a project<br />

to identify and confirm the sustainable<br />

benefits of renting equipment. Three<br />

specialised, independent research com-<br />

panies - Climate Neutral Group, CE Delft<br />

and SGS Search - all researched and calculated<br />

the CO2 emissions during the a<br />

life-cycle of ten pieces of equipment representative<br />

of the portfolio of European<br />

Rental Association (ERA) members.<br />

The research concluded that efficient<br />

use lowers the total carbon footprint<br />

of the pieces of equipment and that the<br />

rental business model stimulates efficient<br />

use. Depending on specific user<br />

practice, we estimate that this can lead to<br />

significant reductions, in the range of 30<br />

percent and sometimes over 50 percent.<br />

Key drivers of the<br />

environmental credentials of<br />

renting:<br />

1. Shared usage<br />

Construction companies can access<br />

equipment when required, rather than<br />

deal with purchase costs, maintenance,<br />

depreciation and expensive equipment<br />

cost lying unused – or being in the wrong<br />

place for a particular project.<br />

Centralised ownership leads to more<br />

frequent and efficient use of equipment,<br />

driving down costs.<br />

2. Repairability<br />

It’s logical that rental companies contribute<br />

to product design – after all, they<br />

need the confidence to reassure customers<br />

that the equipment is fit for purpose.<br />

Their experience can also help make<br />

maintenance and repair faster and less<br />

expensive for all concerned.<br />

42 maintworld 4/<strong>2019</strong>


MARKET<br />

At the same time, shifting the emphasis<br />

on spare parts management purely<br />

from OEMs to rental companies ensures<br />

that spares are available to customers<br />

when and where they’re needed.<br />

Arming rental companies with increased<br />

information on product repairs<br />

can also make the difference between<br />

bringing the job in on time and to budget,<br />

or running over and risking penalty<br />

clauses. Needless to say, that matters to<br />

customers.<br />

3. Resource use<br />

Equipment that is designed, built,<br />

operated and maintained in the most<br />

environmentally-sensitive way can make<br />

a substantial difference to the use of precious<br />

resources over time.<br />

That’s something that will increasingly<br />

be taken into account; when rental<br />

companies have the choice, they offer<br />

the most sustainable option to their customers.<br />

Being able to provide virtual and<br />

practical training to optimise the use of<br />

equipment is also of great value to rental<br />

companies and their customers.<br />

4. Reusability<br />

In the past, it may have been cheaper or<br />

easier to scrap whole pieces of equipment.<br />

Today, with improved design,<br />

build and quality of materials, components<br />

from dismantled construction<br />

equipment can be reused.<br />

5. Recyclability<br />

Rental companies take care of their<br />

equipment by:<br />

Repairing it, when that is still an option.<br />

Better understanding of the equipment,<br />

plus better information regarding<br />

repairs, and access to the necessary<br />

parts, can keep equipment alive longer –<br />

physically and economically.<br />

Recycling equipment at the end of its<br />

life when repair is no longer possible,<br />

or financially viable, to save energy and<br />

reduce waste.<br />

Selling it to second-hand markets,<br />

provided it still complies with regulations.<br />

Rental companies are also able to use<br />

their bargaining power to demand that<br />

equipment suppliers invest more in research<br />

and development to limit the use<br />

of non-recyclable material, and take responsibility<br />

for end-of-life of equipment<br />

by collecting, reusing or recycling.<br />

BY RENTING EQUIPMENT YOU HAVE ACCESS<br />

TO THE RIGHT PRODUCT WHEN YOU NEED IT.<br />

Rental can mean ownership.<br />

If that sounds like a contradiction, consider<br />

this. Taking ownership of – or, if<br />

you prefer, responsibility for – sustainability<br />

puts you in the driving seat of an<br />

entire industry.<br />

Our own recent research found that<br />

rental companies are increasingly insisting<br />

that original equipment manufacturers<br />

(OEMs) become trusted, sustainable<br />

suppliers.<br />

That means taking measures to<br />

reduce energy consumption through<br />

monitoring technologies and hybrid<br />

power systems. The use of low-emission<br />

vehicles and improving the recycling of<br />

waste and end-of-life equipment are also<br />

priorities.<br />

These are important developments<br />

and show a welcome change in thinking<br />

– by the OEMs and the rental companies.<br />

What they highlight is the growing demand<br />

for eco-friendly equipment – and<br />

an eco-friendly market place.<br />

ASSET MANAGEMENT<br />

Automation and Digitalized<br />

Asset Management Increase<br />

Safety and Productivity<br />

Text: Toni Ahonen, Jari Ahola,<br />

Timo Malm, Pekka Isto and Aki<br />

Aapaoja, VTT Technical Research<br />

Centre of Finland<br />

Autonomous systems are revolutionizing many industries, resulting in safer and<br />

more efficient processes. New technologies, services and data are generating new<br />

business opportunities while the mobile machinery industry is currently driven by<br />

increasing customer needs for automatization, electrification and digitalization.<br />

ANOTHER RISING ISSUE is improving<br />

safety in hazardous areas. There is a<br />

market for remotely-operated and/or<br />

automated work machines. While the<br />

current sources of sensory data are not<br />

sufficiently reliable in harsh conditions,<br />

technology is continuously evolving and<br />

the opportunities are increasing daily.<br />

Towards autonomous mobile<br />

machines<br />

Safety, quality, cost-efficiency and<br />

traceability of work processes can be<br />

improved by automation and remote operation.<br />

Figure 1 introduces a roadmap<br />

towards autonomous mobile machines<br />

where the development phases from<br />

Figure 1. Roadmap towards autonomous mobile machines.<br />

manually operated machines towards<br />

autonomous operation are presented.<br />

As the level of automation of manually-operated<br />

machines increases, the next<br />

development phase is typically a machine<br />

with enhanced manual operation.<br />

Assisted manual operation requires the<br />

operator on site to control the machine,<br />

or speed and position is under control<br />

without specific operator actions for<br />

each actuator.<br />

The next step up from enhanced manual<br />

operation is to develop automatic<br />

features or to extend the machine with a<br />

teleoperation interface. The chronological<br />

order of introducing automatic and<br />

teleoperation features depends on the<br />

machine type, business environment<br />

and machine builders’ strategic choices.<br />

In the mining industry, teleoperation<br />

of machines improves ergonomics and<br />

safety, as operators do not need to enter<br />

or stay for long periods in hazardous<br />

areas. When the automatic machine is<br />

extended with a teleoperation interface,<br />

the remote operator can connect to the<br />

machine via a low latency network and<br />

monitor the machine via a real-time<br />

video stream. Machines with automatic<br />

or teleoperation features, or both, currently<br />

exist.<br />

Total data integration is a prerequisite<br />

for remote autonomous mobile machines.<br />

In total data integration, all available<br />

data from the machinery is collected<br />

and integrated into a single data model<br />

for further processing and analysis. The<br />

final development phase of the roadmap<br />

is remote autonomously operating<br />

machines that are connected via a low<br />

latency network. In the future, autonomous<br />

machines will be capable of accomplishing<br />

more complex tasks than their<br />

automatic predecessors. Furthermore,<br />

autonomous machines are able to react<br />

to unexpected events. Due to robust automation,<br />

remote autonomous machines<br />

are capable of operating long periods<br />

without direct user intervention. However,<br />

remote autonomous machines also<br />

include a fail-safe mode in case of unexpected<br />

breakdowns or failures, which can<br />

be conveniently handled by the remote<br />

operator via a teleoperation system.<br />

ASSET MANAGEMENT<br />

Safety strategies and<br />

concepts for autonomous<br />

and semi-autonomous mobile<br />

work machines<br />

Strategy for improving the safety of autonomous<br />

mobile machine systems is<br />

essential. The three strategies described<br />

here are:<br />

Rules for automated area and supporting<br />

technology, like traffic lights,<br />

warnings, guidelines and augmented reality.<br />

Economical, but additional means<br />

are often needed to ensure safety.<br />

Isolated area. Access control for isolated<br />

area(s).<br />

Safe separation distance. Tracking<br />

and distance sensors.<br />

Each strategy can be associated to<br />

several safety concepts, which are applied<br />

to achieve adequate safety. Figure<br />

2 shows some examples on how to apply<br />

the strategies in autonomous areas.<br />

With current technology, isolation<br />

is the best-understood means of ensuring<br />

the safety of an autonomous mobile<br />

machine system. For relatively small<br />

systems, machine area isolation is a<br />

Figure 2. Safety concepts to achieve<br />

adequate safety. Top: rules for automated<br />

area, next below: autonomous area is<br />

divided to several isolated areas, which<br />

each have access control. Middle: all<br />

machines and persons are tracked and<br />

controlled by supervisory system. Below:<br />

on-board system is detecting objects<br />

mainly in front of the machine.<br />

practical way of achieving adequate safety.<br />

In large open systems, however, barriers<br />

become unfeasible due to the length of<br />

barrier required. Isolation is therefore not<br />

a sufficiently scalable strategy and can become<br />

expensive.<br />

Applying rules to an autonomous system<br />

is a scalable and economical strategy,


ASSET MANAGEMENT<br />

but the safety of rules-based solutions is<br />

considered relatively low. The strategy<br />

entails some investment costs in the<br />

form of traffic lights, traffic signs and<br />

road markings, as needed, as well as personnel<br />

training.<br />

The safe separation distance strategy<br />

has a clear technological orientation,<br />

as the distance between personnel and<br />

moving machines must be measured.<br />

Currently, all sensors have certain weaknesses<br />

depending on the operating conditions<br />

or environment; however, sensor<br />

technologies are improving constantly<br />

and prices are coming down. Sensor fusion<br />

can also tackle some weaknesses of<br />

individual sensors. Indoor safety can be<br />

usually addressed by applying low speed<br />

limits and appropriate safety sensors.<br />

Outdoor safety is more problematic as<br />

sensors are less reliable in rain, fog or<br />

muddy conditions and longer driving<br />

distances require relatively high speeds<br />

(manual driving vs. automated driving<br />

speed). The separation distance strategy<br />

is to some extent scalable, but each<br />

object in the area requires technology,<br />

which raises the costs. Outdoor safety<br />

strategies are thus much more exposed<br />

to demanding operating and environmental<br />

conditions.<br />

In all of the three strategies, the challenge<br />

is how to deal with uncertainty. In<br />

the ‘rules’ strategy it is uncertain whether<br />

all personnel will obey the rules. In<br />

the ‘separation distance’ strategy sensor<br />

performance in outdoor applications<br />

is unreliable and highly dependent on<br />

environmental conditions. In the ‘isolation’<br />

strategy the means of isolation<br />

may vary. Locked doors and high fences<br />

guarantee good isolation, but there are<br />

situations when people need to enter the<br />

area. Complete isolation is not practical.<br />

Keys or rules for entering the system<br />

can be applied, but then uncertainty<br />

also increases. Designers of autonomous<br />

mobile machine systems need to accept<br />

some degree of uncertainty, but the risks<br />

AUTO NOMOUS SYSTEMS ARE<br />

REVOLUTIONIZING MANY INDUSTRIES.<br />

must be carefully controlled. Currently,<br />

there are very few good examples of<br />

safe and practical autonomous mobile<br />

machine systems. More examples are<br />

needed, and the standards also need to<br />

evolve in order to define more clearly the<br />

acceptable levels of uncertainty and risk.<br />

Services for asset<br />

management<br />

Increased automation and also the increased<br />

amount of data have enabled and<br />

increased the significance of data-based<br />

services for ensuring the cost-effective<br />

and productive management of the industrial<br />

assets. Increasing demand for<br />

efficiency, quality, capacity and availability<br />

performance of the systems call for<br />

new technologies and implementations<br />

of the asset management standards (e.g.<br />

ISO 55000) that utilize the opportunity<br />

to utilize data, learn from wide machine<br />

Figure 3. Utilization of data analytics based services in asset management.<br />

and component fleets and to integrate<br />

expertise of OEM’s and process experts.<br />

The use and value of predictive analytics<br />

need to be understood in a wider<br />

value context, as depicted in Figure 3<br />

(adapted from Ahonen <strong>2019</strong>). Three<br />

focal topics of asset management are<br />

addressed, namely maintenance, operations<br />

and investment decision-making.<br />

Furthermore, for equipment manufacturers,<br />

one of the main drivers of databased<br />

solutions is the feedback loop to<br />

R&D and product development. This is<br />

particularly important in the transition<br />

to new business models with performance-based<br />

contracting. Thus, since<br />

equipment manufacturers may have<br />

new incentives for stressing different<br />

‘design for X’ aspects in product development<br />

and gathering experience from the<br />

field is of increasing significance.<br />

ISO 55000 defines asset management<br />

as activities that support the realization<br />

of value while balancing financial, environmental<br />

and social costs, risks, quality<br />

of service, and performance related to<br />

assets. Analysis of these tasks from the<br />

viewpoint of more effective use of data<br />

for supporting key decision-making<br />

situations may open up new opportunities<br />

and support the quick technology<br />

experiments carried out by a number of<br />

companies related to development of<br />

digital services.<br />

Conclusions<br />

The demand for automated and remotely-operated<br />

machines arises from<br />

the need to improve the safety, quality,<br />

cost-efficiency and traceability of work<br />

processes. Ecological issues and sustainable<br />

development require minimizing<br />

resource losses while maintaining or even<br />

improving quality standards. However,<br />

the level of automation affects the safety<br />

requirements. The more automated system,<br />

the more requirements there are for<br />

the system, and the more the manufacturer<br />

needs to take responsibility. Thus,<br />

one needs to thoroughly understand the<br />

optional strategies and related concepts<br />

for different operational environments.<br />

At the same time, there is an identified<br />

need for a transition from transaction<br />

and sub-contracting based collaboration<br />

models towards more integrated practices<br />

in company ecosystems. Customers are<br />

expecting more holistic service offerings<br />

and, as the complexity increases, companies<br />

are not able to hold all the required<br />

expertise and knowledge in-house.<br />

Information on recent developments<br />

in the technology and discussion on<br />

the current trends and how to answer<br />

them is provided in more detail in the<br />

for productivity-driven lifecycle services<br />

INDUSTRY EVENT<br />

Figure 1. The view from Sentosa<br />

beach reminds that Singapore is one<br />

of the world’s busiest ports.<br />

Increasing complexity,<br />

interdependency and<br />

connectivity through<br />

digitalization characterize the<br />

current society and the engineering<br />

systems involved.<br />

The World Congress <strong>2019</strong> in<br />

Singapore offered a forum<br />

for cross-fertilization across<br />

the disciplines by bringing<br />

the professionals in asset<br />

management, reliability and<br />

resilience together.<br />

THE ONGOING disruptive trends such as<br />

digitalisation, automation, novel business<br />

models and the emergence of cyberphysical<br />

systems (CPS) have resulted<br />

in increased connectivity within and<br />

between infrastructure and industrial<br />

systems. This development leads to the<br />

increasing complexity of the systems of<br />

systems and creates challenges in the<br />

design, operation, maintenance and<br />

renewal of the assets. World Congress<br />

on Asset Management (WCEAM) is<br />

an annual conference that displays the<br />

recent development in the technologies,<br />

methodologies, processes and tools in<br />

the engineering asset management. In<br />

this year, the WCEAM was organized as<br />

a track in the Resilience, Reliability and<br />

Asset Management (WCRRAM) conference<br />

in Singapore. The event brought<br />

together scientists, policymakers, and<br />

practitioners from different continents<br />

to share the latest knowledge, approaches<br />

and experiences to make interdependent<br />

infrastructure and industrial<br />

systems more robust and resilient.<br />

The congress and the networking opportunities<br />

provided a platform to crossfertilize<br />

ideas and develop new insights<br />

for the management of future engineering<br />

assets. The topics of the engineering<br />

asset management track addressed<br />

major sectors of the capital-intensive<br />

industries, mining, public infrastructure,<br />

and service industry asset management.<br />

The reliability track highlighted the key<br />

issues of asset management including<br />

system reliability and safety, and prognostic<br />

health monitoring of complex systems.<br />

The resilience track sessions emphasized<br />

the importance of the societal<br />

aspects of infrastructure and industrial<br />

systems including metrics, modelling<br />

and design for resilience (robustness,<br />

recoverability).<br />

Eras of reliability optimization<br />

World-class keynote speakers’ presentations<br />

provided interesting thoughts and<br />

laid the groundwork for reflections during<br />

the technical sessions. The keynote<br />

provided by Professor David W. Coit<br />

from the Rutgers University, USA, addressed<br />

the development of the reliability<br />

engineering as a path through three<br />

identified eras. These were the eras of<br />

mathematical programming, pragmatism<br />

and active reliability improvement.<br />

He highlighted the progress from individual<br />

analyses towards continuous improvement,<br />

the progress from dynamic<br />

programming to integrated design and<br />

optimization techniques for complex<br />

systems. The discussion related to the<br />

era of active reliability improvement<br />

well covered the aspects also highlighted<br />

by the current conference, namely integration<br />

with new data, continuous optimization<br />

and consideration of resiliency.<br />

Advanced safety analysis<br />

methods needed for<br />

autonomous machinery<br />

Research results and practical experiences<br />

of system safety engineering<br />

methods for autonomous vehicles were<br />

shared in three presentations. Applications<br />

of systems engineering principles,<br />

V-model framework as well as software<br />

safety issues in complex systems were<br />

discussed. Safety requirements and<br />

technologies for autonomous vehicles<br />

are still strongly evolving. Research on<br />

innovative safety engineering and risk<br />

mitigation methodologies are needed to<br />

be able to manage risk arising from the<br />

higher levels of vehicle autonomy and<br />

to enhance the safety of autonomous<br />

systems.<br />

System modelling and multi-criteria<br />

analysis methods for safety analysis of<br />

complex control systems were discussed<br />

in several presentations. Use cases and<br />

experiences from aviation, military and<br />

energy sectors were introduced. Ms<br />

Yuan Yuan from Beihang University presented<br />

a safety analysis method for vehicle<br />

systems having complex coupling<br />

relationships in the perspective of time,<br />

space, function, structure and other aspects<br />

because of the influence of the condition<br />

of the operator, equipment under<br />

control and the operating environment.<br />

The method is based on functional resonance<br />

method (FRAM), Bayesian model<br />

under multi-factor coupling to analyze<br />

the coupling effect of human, machine<br />

and environment and their influences on<br />

the behaviour of complex systems.<br />

Asset management is getting<br />

smarter, but how?<br />

Mr. Brandon Lee from Intech Process<br />

Automation shared thoughts about the<br />

adoption of Industry 4.0 and particularly<br />

concepts for the effective use of data in<br />

different use cases in his keynote. Features<br />

of Smart asset management were<br />

discussed; more specifically Mr. Lee addressed<br />

the opportunity to orchestrate<br />

efficient operation with optimal resource<br />

utilization through smart assets<br />

and methods with capabilities to detect<br />

and predict inefficiencies. Furthermore,<br />

there is an increasing need to design<br />

digital twins alongside with the physical<br />

products and to arrange the related data<br />

collection. He also acknowledged that<br />

new business models, such as digitalization<br />

as a service, digital twin as a service,<br />

manufacturing as a service and intelligence<br />

as a service, will play an important<br />

role in the future. These issues also<br />

offer an important domain for further<br />

research and development. Panel discussion<br />

on “Digitalisation of the World<br />

and its Impacts on Resilience” chaired<br />

by Prof Hans Heinimann (ETH Zurich)<br />

addressed several topical issues that<br />

are common for resilience, engineering<br />

asset management and reliability optimization.<br />

Harnessing the life cycle value<br />

from industrial assets<br />

The technical sessions for asset management<br />

addressed a variety of topics related<br />

to e.g. digitalization, asset services,<br />

investment appraisal and maintenance<br />

planning and strategy optimization. Industrial<br />

and infrastructure viewpoints<br />

were covered and methodologies and<br />

Digital twins and shadows<br />

The concept of digital shadow for determining<br />

the value contribution of<br />

maintenance and maintenance services<br />

was introduced by Frederick Birtel<br />

from FIR at RWTH Aachen University.<br />

The determination of actual value of<br />

maintenance services for companies<br />

should not cover only the optimization<br />

of direct but especially of indirect costs.<br />

The problem for companies in this<br />

context is that they do not know which<br />

data they have to record in order assess<br />

indirect costs and maintenance value<br />

contribution respectively. Antonio de<br />

la Fuente from University of Seville<br />

addressed the practical methodology,<br />

asset criticality and health index<br />

(AHI), for planning major overhaul and<br />

equipment renovation. AHI takes into<br />

account the importance of the assets<br />

for the business (asset criticality) and<br />

determines the asset health projections<br />

over time and NPV of the different<br />

technical alternatives. Moreover,<br />

several presentations comprised the<br />

need for novel maintenance strategies<br />

and data-based business models where<br />

the entire life cycle of products and services<br />

is reconsidered.<br />

frameworks presented from both asset<br />

owner and service provision perspectives.<br />

The sessions provided interesting<br />

insights into the value creation for<br />

industrial asset management. In this<br />

research area, the focus in the conference<br />

was especially on the research and<br />

the real life uses of valuation of data and<br />

the value contribution of maintenance<br />

services as well as the role and value of<br />

THE WCRRAM CONGRESS REVEALED THAT THE VALUATION<br />

OF DATA AND MAINTENANCE SERVICES IN THE CONTEXT OF<br />

ENGINEERING ASSET MANAGEMENT IS HIGHLY TOPICAL AND<br />

THAT THE VALUE OF THE DATA IS NOT FULLY UNDERSTOOD YET.<br />

digitalization in asset management. The<br />

fact is that the digitalization of manufacturing<br />

processes creates vast amounts of<br />

maintenance and production data available<br />

to companies and to entire business<br />

ecosystems. Dr. Salla Marttonen-Arola<br />

from University of Sunderland outlined<br />

the role of data role in asset management<br />

decision-making and presented<br />

the results of a case study on evaluating<br />

the value of data-based profitability of<br />

investing in a CMMS. Moreover, several<br />

innovative value-driven approaches<br />

were introduced in the congress. Sanyapong<br />

Petchrompo presented an<br />

optimisation model for vehicle fleet<br />

maintenance scheduling and Andrew<br />

Hoisington outlined a model to reduce<br />

lifecycle costs for infrastructure assets.<br />

Many of the presentations emphasized<br />

the need for novel strategies and business<br />

models of sharing risks and benefits<br />

when implementing advanced technologies.<br />

Ype Wijnia presented an approach<br />

for modelling the consequences of various<br />

asset replacements in terms of cost,<br />

risk and performance.<br />

The WCRRAM congress revealed that<br />

the valuation of data and maintenance<br />

services in the context of engineering<br />

asset management is highly topical and<br />

that the value of the data is not fully understood<br />

yet. Future research is needed<br />

e.g., on assessment and realization of<br />

value of data for different stakeholders<br />

in industrial value networks. Relevant<br />

topics include business models, contract<br />

types, risk management, and measurement<br />

and demonstration of the value of<br />

data.<br />
