ABL enters MoU with Egyptian-owned
safety specialist
NIS wants Fed Govt to
embark on proper mapping
of Nigeria over insecurity
ABL Group has signed a memorandum of
understanding (MoU) with Petroleum
Safety & Environmental Services Co.
(PetroSafe) to collaborate on safety and
environmental services for Egypt’s oil and gas
sector.
Petrosafe is owned by Egyptian General
The technology group Wärtsilä will
carry out an upgrading project of the
electrical and automation systems to
ensure optimal reliability of the Kribi power
plant in the Republic of Cameroon. The 216
MW plant has been in operation for nearly
ten years, operating with 13 Wärtsilä 50DF
dual-fuel engines running primarily on
natural gas. At the time of commissioning,
it was the largest gas engine power plant
in Sub-Saharan Africa. Wärtsilä will also
support the customer’s operational and
maintenance performance with a 10-year
long-term service agreement.
The order with Wärtsilä was placed by
Kribi power development company (KPDC),
a subsidiary of Globeleq, an independent
power producer (IPP) and the owner and
operator of power generating facilities
across Africa. The order will be booked in
Wärtsilä’s order intake in Q3/2022.
“The Kribi power plant has a vital role
Petroleum Corp.
ABL, an engineering and marine consultancy
based in Oslo, will support the company with
marine engineering and design services,
marine surveys, inspections and audits,
marine warranty survey, and other services to
assist marine casualty management.
Wärtsilä to provide automation upgrade and long-term
service agreement for an iconic power plant in Cameroon
within the African energy sector. It is still
today supplying two-thirds of the thermal
energy in Cameroon. Cameroon’s energy
system relies heavily on hydropower, but
has uncertain resources of water. The Kribi
plant, therefore, plays a key role in ensuring
a supply of safe, cheap, and reliable energy.
For this reason we are keen to upgrade the
power plant’s automation systems to the
latest design to ensure optimal reliability,
and to strengthen our cooperation with
Wärtsilä, leveraging their competences on
a continuous basis within the framework
of the long-term service agreement,”
commented Gionata Visconti, Chief
Operating Officer, Globeleq.
“Wärtsilä has a strong regional presence,
which enables us to provide valuable
technical support that optimises engine
performance and maximises the production
capabilities of this power plant which has
such a significant role in Cameroon’s power
supply. We are also in a position to ensure
the availability of critical spare parts, and
this is an essential element within the
long-term service agreement between
our companies. All in all, this is a very
important project, both for the customer and
for Wärtsilä,” said Markus Ljungkvist, Vice
President, Services, Wärtsilä Energy.
The Nigerian Institution of Surveyors
(NIS) has advised the Federal
Government to initiate proper
geospatial mapping of the nation. It said
that doing so would help in the war against
terrorists, banditry and other criminal
activities. The NIS lamented that the current
maps in operation was done in 1965 and
already obsolete, noting that the first thing
government should do is mapping of the
country to see where the criminal elements
are.
The surveyors stated this in a communique at
the end of their 56th yearly general meeting/
conference with the theme: “Mapping
Policies, Strategies and Spatial Infrastructure
for Sustainable E-governance in Nigeria,”
which took place in Ado-Ekiti from Monday,
July 25 to Friday, July 29, 2022.
The communiqué, read to newsmen
by National President of NIS, Kayode
Oluwamotemi, stated: “The first thing for us
to do to overcome this insecurity is proper
mapping of the entire country. That is when
you will be able to see everywhere and what
is involved.
“With good mapping, we should be able to
tackle insecurity. We are ready to partake
and make Nigeria secure and governable.
The map we are referring to today was
that of 1965 or 1966. Certain percentage,
according to the United Nations (UN), must
be earmarked yearly for mapping, but we
don’t do this in Nigeria.”
The NIS, which appealed for wholly
implementation of the Survey Co-ordination
Act 1962, further said: “There is poor
awareness of the fundamental role of
surveying and mapping in the realisation
of e-governance in the public and private
sectors.

Toshiba ESS, KenGen sign
MoU on geothermal power
cooperation
Japan’s Toshiba Energy Systems &
Solutions Corporation (Toshiba ESS) and
Kenya Electricity Generating Company
PLC, also known as KenGen, have signed a
memorandum of understanding (MoU) to
cooperate in the geothermal power sector in
developing countries including those in East
Africa.
The parties said in an announcement on
Wednesday that the document outlines their
partnership on operation and maintenance
(O&M) services for the geothermal power
plants. The arrangement will also see
KenGen contribute to the development of
geothermal power project in East African
countries.
GeoPartners to acquire 3D seismic over Mozambique’s
Angoche Basin
GeoPartners has signed an exclusive
agreement with Mozambique’s Instituto
Nacional de Petroleo to perform a new
multiclient 3D geophysical survey over the
country’s offshore Angoche Basin.
The program involves acquisition of a
minimum of 12,000 sq km of data over
blocks to be awarded following the closure of
Mozambique’s current 6th Licensing Round.
GeoPartners will apply acquisition and
imaging techniques to improve illumination
of complex structures to help reduce
exploration risk and support potential fasttrack
production and development.
Pre-acquisition permitting is underway, with
the six-month survey due to start early next
year. Early processed results should be issued
by year-end 2023.
South African court confirms Shell seismic exploration ban
“There is an ongoing survey to identify
geothermal resources in the Great Rift Valley,
a tectonic plate boundary running from north
to south with immense geothermal potential.
Both companies are delighted to cooperate
in this opportunity, and plan further business
expansion,” the press release reads.
Both KenGen and Toshiba ESS have the
industry know-how and networks in the
geothermal power sector, which they intend
to the bring to the partnership. The Kenyan
power producer has 799 MW of geothermal
capacity installed. Toshiba ESS had a hand
in the development of multiple geothermal
projects, having delivered 60 geothermal
power generation sets with a total capacity
of around 3,790 MW across the world,
including Uganda, Malawi and other East
African countires. Its steam turbines and
generators are also installed in KenGen’s
plants.
“Geothermal energy provides sustainable
power supply. It is a resource we have in
abundance in Kenya, an advantage that
has enabled us to build a considerable
wealth of expertise in its exploration and
development. This we have done for more
than 50 years,” commented Rebecca Miano,
KenGen managing director and CEO.

A
South African court upheld an earlier
ban imposed on energy giant Shell
from using seismic waves to explore for
oil and gas off the Indian Ocean coast.
The judgment delivered in the southern
town of Makhanda marked a monumental
victory for environmentalists concerned
about the impact the exploration would have
on whales and other marine life.
The 2014 decision granting the right for the
“exploration of oil and gas in the Transkei
and Algoa exploration areas is reviewed and
set aside,” the high court in the southern city
of Makhanda (formerly Grahamstown) ruled,
according to judgment seen by AFP.
Civil rights organizations and civilians
celebrated outside the courthouse following
the verdict, according to local media.
A Shell spokesperson said they “respect the
court’s decision” and that they would review
the judgment to “determine our next steps”.
Shell did not say if it will appeal the
judgment or not.
“We remain committed to South Africa and
our role in the just energy transition,” he
said.
Last December the same court issued an
interim order prohibiting the company firm
from forging ahead with its plans.
The petroleum giant was set to collect 3D
seismic data over more than 6,000 square
kilometers (2,300 square miles) of ocean off
South Africa’s wild coast — a 300-kilometer
(185-mile) stretch of rich waters housing
exquisite marine life and natural reserves.
Campaigners argued that the research
would have sent “extremely” loud shock
waves every 10 seconds, 24 hours a day for
five months, potentially harming marine
species, and disrupting their routines.

New Esri Initiative
provides Free
Geospatial Software for
Nonprofits
Nonprofits are increasingly taking a
geographic approach to implementing
their plans and ensuring the success
of their goals. One nonprofit organization
recently used geospatial technology to
target likely donors as well as identify areas
in need while addressing the recent baby
formula shortage. To support and advance the
missions of similar small nonprofits that may
think geographic information systems (GIS)
software is out of reach, Esri, the global leader
in location intelligence, has launched the Esri
Small Nonprofit Organization Grant Initiative.
The grant initiative will provide 150 501(c)
(3) nonprofit organizations with access to GIS
training and software.
“The Esri Small Nonprofit Organization Grant
Initiative is focused on enabling nonprofits
to leverage GIS to achieve their goals
while cooperating with local communities,”
said Christopher Thomas, Esri director of
government markets. “We are proud to assist
small nonprofit organizations that are new
to GIS, while helping them understand the
unique perspective and new insights location
brings to data.”
The GIS technology available to grantees
will empower nonprofits of all sizes to
better communicate their cause, understand
communities, act on their mission, measure
impacts, as well as extend services, attract
volunteers, expand donor networks, and
shape public policies.

FarSounder Partners with Propspeed for
Biofouling Solution
FarSounder has
approved Propspeed
FoulFree as an
acceptable coating for the
Argos sonar array face to
limit biofouling. As a result,
the companies have come
together to offer the first
application of FoulFree at
no charge with each new
Argos purchase.
FoulFree is a specialized
foul-release coating that
is biocide free and not
harmful to marine life.
Designed to limit the
adhesion of biofouling,
this product is certified by Airmar and results
in no loss in transducer performance once
applied. For a limited time, all new orders of
Argos forward facing sonars are eligible for
a complimentary FoulFree Application Kit.
FarSounder customer should request the kit
at time of order, and it will be included in
the Transducer Module’s package.
Keeping your Transducer Module’s array face
clean from marine growth is important for
optimal sonar performance. While simple
Washington-based Hydrosat, a
geospatial data and analytics startup,
announced July 29 it has secured U.S.
regulatory approval to provide global services
from its upcoming thermal imaging system.
Hydrosat was awarded a National
Oceanographic and Atmospheric
Administration license at Tier 1, which has
the fewest conditions under a streamlined
regulatory regime that came into effect
in 2020. Tier 1 systems have capabilities
deemed similar to systems that are not
licensed by the U.S. Commerce Department,
such as the U.S. government’s Landsat-9
satellite or foreign commercial systems.
Tier 2 remote sensing ventures offering
data matched only by other U.S. systems,
and Tier 3 systems seeking to provide a
“completely novel capability,” are subject to
stricter regulatory constraints which make
cleaning methods can be used to remove
growth, applying a coat of FoulFree to the
urethane can significantly reduce the amount
of fouling to be cleaned.
The accumulation of biofouling can cause
damage to the mechanics of a vessel over
time, including a sonar array face. FoulFree is
one solution that has been tested and proven
to not be harmful to marine life or ship
mechanics. This makes it an ideal product for
environmentally continuous mariners and
companies like FarSounder.
Hydrosat secures Tier 1 remote sensing operating license
it more difficult to sell commercially or
internationally.
Hydrosat CEO Pieter Fossel said Tier 1
certification for VanZyl-1, Hydrosat’s first
satellite mission which is set to launch on a
Loft Orbital condosat via a SpaceX Falcon 9
rideshare mission early next year, gives the
startup the highest degree of flexibility in
how it can collect and sell data commercially.
The license “gives us the most freedom to
operate independently, and signifies that
NOAA has determined that what we’re doing
as a commercial organization, as an exporter,
as a job creator is worthwhile,” Fossel said.

eBee X Series Drones are World First to Receive EASA’s C2 Certificate
INTERNATIONAL
SenseFly, an AgEagle company
announces that eBee X, eBee Geo
and eBee Ag are the first commercial
drones to be designated with the C2 class
identification label in accordance with the
European Aviation Safety Agency (EASA)
regulations. As of August 22, 2022, drone
operators flying C2 labeled eBees will
be able to conduct missions in the “Open
Category”, with all the advantages that this
entails.
The C2 certification allows the eBee X series,
with correct labelling, to fly at a horizontal
distance of 30 meters from uninvolved
people. By contrast, heavy drones like VTOLs
or quadcopters must maintain a distance of
150 meters from people and any residential,
commercial, industrial and recreational
areas, limiting their operational capabilities
to remote zones.
According to Barrett Mooney, Chairman
and CEO of AgEagle, “When compared to
the weight and safety profiles of other
competitive commercial drones, only the eBee
are cleared to fly commercial operations near
people with the C2 class identification label.
This represents a huge market differential for
our customers in Europe, that will be able to
operate around populated areas without any
formal permission or regulatory waiver”.
In addition, the eBee X series are also the
industry’s first drones (June 2022) to receive
a Design Verification Report (DVR) from
EASA on M2 Ground Risk Mitigation for the
European “Specific Category” to conduct
BVLOS and Operations Over People (OOP).
The DVR paves the way for European drone
operators to seek approvals from their
applicable National Aviation Authorities.
To be designated as a C2 aircraft, eBees
underwent rigorous testing and evaluation by
the accredited laboratory NavCert GmbH to
confirm that they meet specific EASA criteria.
C2 class aircraft must weigh less than 4 kg
/ 8.8 lbs maximum takeoff weight (MTOM),
have remote ID and geo-awareness, and be
compliant with the safety and manufacturing
standards of the European Union.
Marcel Visser, Managing Director of NavCert
GmbH, stated, “We congratulate senseFly on
this important achievement, and we wish
them a high market share for the eBee X
series drones. We are grateful that NavCert
has been selected as the Notified Body (NB
2603) to assess the eBee X series fixed-wing
drones for the CE mark."
Traffic Design Data Manager from Phocaz Is Powered by the Bentley

easier to check and cross-reference project
designs.
“Traffic Design Data Manager evolved from
our clients’ desire to understand how the
Bentley iTwin platform can solve the types
of problems they might encounter,” said Mark
Stefanchuk, CTO of Phocaz, Inc. “Encouraging
the quality team to use a paperless process
sounds simple. But reviewers who don’t
regularly interact with technologies like CAD
or GIS can be highly resistant. So, with Traffic
Design Data Manager, Powered by iTwin, we
can introduce browser-based workflows that
are more familiar to more users. We added
reports whose records automatically synch
with graphics making navigation to points
of investigation simple—and it’s faster than
using paper.”
“We are very pleased to have Phocaz add
their Traffic Design Data Manager application
to the Powered by iTwin program,” said Adam
Klatzkin, Vice President, iTwin Platform,
at Bentley Systems. “In doing so, Phocaz
joins the growing ecosystem of software
developers enabling digital twin solutions
with the Bentley iTwin platform. Traffic
Design Data Manager is a great example
of how digital twin technologies can
improve roadway design and construction
by automating the capture of design quality
issues and increasing data trust across
traditionally siloed discipline domains.”

Cape Town expo powers the Western
Cape’s R23 billion construction sector
investment in the residential sector. “The municipality continues to
outperform other regions due to its ability to process building plans
and complete building projects with little interruption,” he says.
Mark Fugard, Senior Vice President of Master Builders Association
Western Cape says that the Western Cape residential market
has also benefitted from migration and semigration from other
provinces. However, he adds that many of their members have found
themselves in an overly competitive environment due to insufficient
market opportunities. “The construction industry in the Western
Cape requires an increase in investment from national and local
government as well as continued support from the private sector to

employment for over 475,000 people nationwide, with around
one third of these employees living in Cape Town. The Mother
City is home to an equally thriving construction sector, which
contributes over R20 billion to the city’s economy each year.
At a provincial level, the Western Cape construction industry is
experiencing swift growth, with research from StatsSA from May 2022
revealing the province as the national leader in terms of total value of
residential building plans passed and completed. Accounting for 34%
.13 of the national total of building plans passed, compared to 29.8%
in Gauteng, it also boasted 40% of the national share of buildings
completed, compared to 31.3% in Gauteng.

Censys Technologies Integrates LiDAR into its
Fixed-Wing VTOL Drone
Censys Technologies Corporation is
bringing LiDAR to its list of universal
payload options. Censys, a trailblazer
in the commercial beyond visual line of
site (BVLOS) unmanned aerial systems
(UAS) industry, offers a one-of-a-kind
remote sensing package to revolutionize
the way aerial information is collected for
infrastructure, agriculture, public safety and
more, by bringing together the best software
and hardware solutions in the world of
airborne intelligence. Now, it is integrating
LiDAR into its Sentaero family of fixed-wing
vertical take-off and landing (VTOL) aircraft
capable BVLOS.
LiDAR – Light Detection and Ranging – is
a remote sensor camera payload that uses
pulsed laser light for 3D mapping. The LiDAR
measures the time it takes that reflected
laser light to return to the receiver after
bouncing from the ground and measures the
intensity of the pulses to provide readings
of the terrain and points on the ground.
This technology is especially useful for land
surveying, power line inspection, topographic
surveys, forestry and wildfire mitigation,
precision agriculture, and mining.
“In a fixed-wing VTOL with a history of BVLOS
approvals, this is a huge addition to the
Sentaero line,” said Censys Technologies CEO
and Co-Founder Trevor Perrott. “We’ve been
working hard to integrate LiDAR over the past
year to fill customer needs, and now operators
who had been chained to quadcopters have a
new option to do more.”
In a single flight, fixed-wing drones carrying
a LiDAR payload have a system precision of
2.5 centimeters and system accuracy of 3
centimeters at 100 meters above ground level
(AGL). Censys anticipates deliveries of the
LiDAR payloads to customers in August 2022.

OPINION
Total focus on renewables and
gas is the cheapest way to meet
Mozambique’s new electricity demand
“The challenge
facing policy
makers today
is to identify
and develop an
optimal energy
mix at the
lowest total cost
to service this
growing demand
Wallace Manyara
Business Development Manager
Region South & East Africa, Wärtsilä Energy
To meet its growing energy needs and
increase electricity access across the
population, Mozambique must build
1.3 GW of new power capacity over the next
decade. A further 2 GW would be needed to
support the planned development of the
Beluluane Industrial Park in the Maputo
province. The challenge facing policy makers
today is to identify and develop an optimal
energy mix at the lowest total cost to service
this growing demand. A recent study carried
out by Wärtsilä shows that investing in a
combination of renewables and gas would
save $2 billion and 25 million tons of CO2
by 2032 compared to adding new coal fired
capacity.
Working in cooperation with EdM
(Electricidade de Moçambique), to assist
the country in developing its long-term
electricity plan, Wärtsilä has examined how
an optimized power system expansion would
look like with the competing technologies
and fuels available, under different demand
increase scenarios from 2022 to 2032. With
its huge reserves of coal and the development
of its immense gas fields, Mozambique has
plenty of power generation potential. The
14 July-August issue l 2022 www.africasurveyorsonline.com

country also has impressive yet untapped,
low-cost wind and solar resources. But which
power mix is going to be the most costeffective?
Using its advanced Plexos power system
modelling tool, which applies a chronological
model to integrate the dispatch challenges
of the intermittent output of low-cost
renewables, Wärtsilä is able to quantify
system level benefits of different generation
and storage technologies to find the lowest
cost solutions. The models consider existing
power capacity, committed capacity additions,
including the 450 MW Temane power plant to
be commissioned in 2024, as well as capacity
expansion candidates including coal, gas, and
renewables.
The different scenarios modelled clearly
show that investing in new coal fired capacity
would not only generate higher emissions
and higher costs, but it would also slow down
investment in renewables. Why? Because
any coal fired power plant, in addition to the
combined cycle gas-turbine plant which is
currently under construction in Temane, would
provide the country with significant baseload
capacity, without the flexibility required to
integrate cheap renewables on the grid.
The cost of solar PV generation has
plummeted over the past decade, making it
the lowest cost source of energy, especially in
Southern Africa. The cost of wind farms has
declined significantly too. However, for the
power system to benefit fully from these lowcost
sources, it requires flexible alternatives,
capable of adjusting output rapidly in
response to the intermittence of renewables,
to maintain a balanced system and prevent
power outages. Thermal coal and gas turbine
power plants are designed to operate most
efficiently at full capacity, producing a stable
baseload, and are therefore ill-suited to
adapt their output in response to supply
and demand fluctuations. Relying on these
technologies to balance the grid is inefficient,
leading to higher operating and maintenance
costs, lower margins, as well as higher
emissions.
Lower emissions and lower costs
with flexible gas engine technology
Advanced energy system modeling
demonstrates that gas engine power plants
are best suited to support renewables thanks
to their flexibility. Comprised of multiple
generating units, which can be fired up
instantaneously, they offer a large range in
power supply availability without sacrificing
efficiency. When considering a full fleet of
assets, these flexible power plants can not
only unlock the full potential of renewable
energy assets, but they also offer the lowest
levelized cost of energy (LCoE) as well as
reduction in CO2 emissions.
The model shows that investing in
renewables, together with flexible gas
capacity and energy storage, is the optimal
energy mix to support demand based on
moderate growth projections. By 2032,
focusing on renewables supported by flexible
gas would generate savings of 25 million
tons of CO2 emissions and $2 billion dollars
in total costs when compared to a coal-based
scenario. To provide the additional 2 GW of
electricity to serve the Beluluane Industrial
Park, the cost optimal solution would combine
1 GW of wind and solar capacity together
with 2.6 GW of new baseload and flexible gas
projects.
Moreover, the installation of low-cost solar PV
and wind farms combined with the support
of flexible power generation utilizing its
gas resources, respects the realities of the
country. Renewable off-grid projects and
energy storage systems would support
electrification in rural and more remote areas
of Mozambique and strengthen the country’s
underdeveloped transmission and distribution
network.

OPINION
A marked shift away from coal
The last decade has seen a significant shift
in the power sector driven by the energy
transition. There is clearly a lot of pressure
from the markets to shift away from coal.
In an industry where assets are built to last
more than 20 to 30 years, the economics of
new coal-fired power station developments
are now less and less appealing. This
presents a very strong case for flexible gas
capacity as part of the cost optimal path
towards a massive integration of renewable
energy. Wärtsilä has modelled the regional
power systems across South Africa, Namibia,
Botswana and Zambia. All these countries
plan to decommission aging coal plants and
install significant amounts of renewables
over the next decade; and flexibility is key to
supporting these plans.
The decisions taken today to build the right
energy mix will have significant impact on
the transition to cleaner energy not just for
Mozambique, but for Southern Africa as a
whole. Today, Mozambique is a net exporter of
coal and gas. By utilizing its vast natural gas
resources to develop its domestic electricity
network with flexible capacity, Mozambique
will have the unique opportunity to meet
both its domestic goal of providing universal
electricity access and become a major
exporter of flexible energy to promote
development of renewables across the region.

MINING
Anglogold Ashanti Obuasi Mine supports
agric officers to fight climate change
Anglogold Ashanti Ghana, Obuasi
Mine has presented Agricultural
Extension tools to Agric officers in
five districts of the Ashanti Region. The tools
which included flip charts, pruning tools,
harvesting tools and tablets, were to support
AGA’s Climate Resilient Oil Palm Project
(CROPP) which is part of the 10-year Socio-
Economic Development Plan of the mining
company.
The beneficiary districts were Obuasi
Municipal, Obuasi East, Adansi North, Adansi
South and the Adansi Asokwa districts.
Launched in 2021, the Climate Resilient Oil
Palm Project (CROPP) aims at mitigating the
effects of climate change and adaptation
through local economic development.
The five-year programme, which is expected
to be rolled out in five districts, has
Solidaridad West Africa providing technical
support. As part of the program, Extension
Officers in the beneficiary districts have
been trained in Best Oil Palm Management
practices and the use of digital tools for
monitoring and reporting purposes.
Ghana, like most sub-Saharan African
countries, is predominantly agrarian, with
crop production being the main driver of the
agriculture sector.
More than 80% of growers are smallholder
farmers, and their practises are characterised
by low technology use, high rain dependence
and low adoption of irrigation. Less than 2%
of arable lands in Ghana are under any form
of irrigation.
Thus, the over-dependence on quantity and
pattern of rainfall for crop production in
Ghana exposes the economy and livelihood
of citizens to fluctuation in production.
This has been exacerbated by the growing
unpredictability of weather caused by climate
change.
Speaking at an orientation program held
in Obuasi to brief stakeholders on the
progress of the CROPP, Emmanuel Baidoo,
Senior Manager Sustainability AGAG, said
CROPP is a demonstration of commitment
on the part of AGAG to support farmers to
improve productivity on their oil palm farms,
expand their production by reclaiming and
developing degraded lands into agroforestry
oil palm farms and implement additional
livelihoods.
He said, the key to the 10-year Socio-
Economic Development Plan (SEDP) launched
in July was Agricultural Development. He said
it is a deliberate policy of AGA to diversify
the economy of Obuasi by leveraging on
agricultural development.
To execute this, he stressed that the project
will support existing oil palm farmers in the
5 MMDAs to adopt climate-smart practises
through capacity building and technical
support, the project will also work with chiefs
and local authorities to identify and convert
degraded lands into oil palm agroforestry
blocks.
“The CROPP will facilitate the set-up of an
oil palm nursery to supply climate resilient
seedlings to farmers as well as strengthen
oil palm farmer groups through the Village
Savings and Loan Association (VSLAs) and
will anchor support and technical assistance
through the VSLA groups as well as link them
to rural/ community banks”, he added.
He also underscored the importance of
monitoring the sustainability of the program.
He said that Anglogold Ashanti, in the five (5)
years duration of the program, will actively
invest in the value chain with the aim of
realising the objectives of the program.
The Economic Development Superintendent
of Anglogold Ashanti, Daniel Arthur-Bentum
in his presentation mentioned the roles of the
various stakeholders in the implementation
of the CROPP.
He said Anglogold Ashanti is responsible
for mobilising technical and financial
partnerships to support the program. They
will also support MMDAs with resources
for implementation of the program. He
added that Solidaridad West Africa will
provide technical training, mentoring and
coaching to MMDA extension staff, provide
a platform for monitoring and reporting on
project outcomes, train and mentor youth
farm service providers and provide technical
support toward the establishment of oil palm
agroforestry farms.
On the part of the MMDAs, Mr. Arthur-Bentum
stressed that they will identify and train
farmers on BMPs, conduct follow-ups and
provide extensive support to existing and
new oil palm plantings and collect monthly
data from selected farmers using SWA
platform. He appealed to chiefs and leaders
of the beneficiary communities to make
available degraded sites for reclamation.
Rosemary Addico, Oil Palm program Manager,
Solidaridad West posited that a lot of
farmers especially smallholder farmers have
limited knowledge in the best management
practises hence the CROPP will help build the
knowledge and capacity of farmers in the best
management practices to enable them adopt
the right approaches to farming.
Chiefs, MMDCEs from the beneficiary districts;
Agric officers and farmers were all present at
the orientation program.

COVER STORY
Geological Survey
Understanding the earth's structure
Geological maps are based on geological
information and illustrate the geological
features on a topographic map. The information
on these maps is used to interpret the earth's
crust. They are particularly valuable for locating
mineral deposits, potential hazards, and energy
resources
22 July-August issue l 2022 www.africasurveyorsonline.com

GEOLOGICAL SURVEY
A
Geological Survey is a systematic investigation of the Earth's geology. It is
performed to create geological models and maps. This process is crucial in
helping scientists better understand the earth's structure. It can also be helpful in
disaster prevention and management. A Geological Survey is conducted to identify areas
of concern and to create a map of the area.
Geological maps are based on geological information and illustrate the geological
features on a topographic map. The information on these maps is used to interpret
the earth's crust. They are particularly valuable for locating mineral deposits, potential
hazards, and energy resources. They are also a basic source of information for
engineering applications.
Geological surveys use several techniques to get the information needed for projects.
These include conventional visual survey, studying landforms, drilling holes by hand
or using a machine, and using remote sensing techniques such as satellite images and
aerial photography. They also use geophysical equipment to detect earthquakes. For
earthquakes, geophones are placed at strategic locations to help geologists identify
earthquakes.
Geological surveys are also used on the coastal geology such as the placement of
dredged materials. Another major program is economic geology, which incorporates
aspects of the other programs. This includes bedrock quarries, sand and gravel
resources, and aquifer use. This type of survey also provides professional services, such
as conveying geologic information to other agencies and the public. It also engages in
public outreach, such as identifying fossil specimens and rocks.
The USGS is an important source of basic earth science information. The agency provides
information to the public and other government organizations, as well as undertakes
mapping in foreign countries. Besides providing data for natural resources and disaster
preparedness, the USGS also undertakes research and assists governments in disaster
response and environmental management. The USGS is one of the most reliable sources
of information on Earth's ecosystems.
The Mineral Deposits Section also conducts research in the field of metallogeny, a
branch of geology that seeks to identify the genetic relation between mineral deposits
and geological history. This research helps to direct private exploration efforts toward
areas with high mineral exploration potential. This research includes both detailed
studies of individual deposits as well as regional metallogenic studies of the earth and
describes its mineral resources.

provides convenient
stereoscopic geospatial
data acquisition and
processing.
With the flexible and mature
photogrammetry environment
ImageStation® from the
Swedish metrology and geospatial software
company HEXAGON, particularly large
amounts of aerial images, UAS and satellite
data can be efficiently processed, managed
and utilized for geodata acquisition. A core
task, which is solved most efficiently with the
ImageStation® photogrammetry
environment, is the precise, interactive
capture of 3D objects, the entire
infrastructure, such as buildings, roads and
bridges, but also natural terrain features.
In Germany, the topographical surveying and
updating / tracking of the entire
infrastructure is the responsibility of the
surveying offices in each of the 16 German
states or ‘Laender’. The ImageStation® was
specially developed for professional
photogrammetry and cartography users and
provides a comprehensive set of data
acquisition tools. In order to be able to move
intuitively and measure precisely in this
stereoscopic, three-dimensional reality, an
important interface element was integrated
into this high-tech software right from the
beginning: the 3D stereo mouse cursor. The
stereoscopic mouse cursor implementation is
a prerequisite for working with precise 3D
data controllers and enables perfect
interaction with the plug & play compatible
and powerful 3D PluraView monitor systems
from Schneider Digital. The passive 3D
monitors from Schneider Digital with
beam-splitter technology impress by
pixel-precise visualization of up to 4K (UHD)
per stereo channel, fast image frame rate,
high color depth, high brightness and
contrast values.
With its certification, Schneider Digital
confirms that the powerful ImageStation®
software suite is fully compatible with this
professional hardware and thus meets all the
requirements of international workplace
standards: Two compatible cutting-edge
technologies that merge into a complete
solution and an ideal combination for
professional photogrammetry users.
The collection and updating of topographical
geoinformation datasets is a complex task
from a scientific, technical and organizational
point of view. The comprehensive
photogrammetry solutions from the Swedish
metrology and geospatial software company
HEXAGON support users worldwide in the
acquisition, management and evaluation of
multi-temporal, static and dynamic geospatial
data. In order to convert particularly large
amounts of raw data into easy-to-use and
actionable information, HEXAGON has further
developed the software application
ImageStation®. More than 40 years of
photogrammetric 'know-how' have gone into
this modern application, starting with
analytical stereoplotters and culminating in a
complete software suite for digital
photogrammetry, including a perfect
stereoscopic 3D cursor implementation.
Smooth GIS Workflow
With its photogrammetry solutions,
HEXAGON ensures a seamless workflow for
the processing of high-resolution image data
and geocoded CAD and GIS content from
project start to finish. In classic aerial
photogrammetry, project blocks are flown in
laterally overlapping strips, whereby image
overlaps of up to 90% in flight direction are
realized and frame rates of 0.5 to 0.7 seconds
represent the current state of the art. With
the simultaneous recording of oblique aerial
images, more than 3-GB of image data can be
created for each exposure center. Project
blocks with over 50,000 exposure stations,
5cm ground resolution and over 150-TB of
initial image volume for urban areas, can now
be commonly realized and calculated.
Users of the ImageStation® software suite
benefit from the many interactive stereo
functions of this powerful photogrammetry
application: smooth roaming, dynamic zoom
and real-time image enhancement are
integrated directly into the GIS or CAD
environment. The ability to perform stereo
and mono compilation directly in a GIS
environment enables direct comparison with
and seamless continuation of existing GIS
databases, resulting in a significant increase
in efficiency. This not only saves valuable
time and resources, but also reduces the cost
of creating topologically correct 3D data.
3D-Cursor - integrated into software
applications
HEXAGON has perfectly implemented a
professional, stereoscopic 3D cursor in the
ImageStation®. This functionality enables
users to intuitively and smoothly navigate for
the precise capture 3D objects with their
real-world XYZ coordinates. In addition to the

Process geospatial data quickly and
precisely
The photogrammetric ImageStation®
software suite is used worldwide and
especially at state surveying offices and by
users from industries such as aviation,
shipping and national defense. With the
ImageStation®, geospatial data can be
processed quickly, efficiently and costeffectively.
For example, the ImageStation
Stereo Display (ISSD) application supports
viewing and editing of stereo images with
photogrammetrically accurate 3D-cursor
tracking. ISSD accepts aerial or satellite data,
images from drone (UAS) projects, as well as
from the Leica ADS 3-line cameras. The
ImageStation® Suite enables the automatic
and dynamic adjustment of image brightness
and contrast in the MicroStation and
GeoMedia environment. The exclusive
ImageStation® ImagePipe technology is
responsible for smooth stereo roaming,
providing the perfect image representation
that is essential for efficient stereo
compilation.
Stereoscopic geospatial data acquisition and
processing
HEXAGON ImageStation® Stereo for
GeoMedia (ISSG) is based on the GeoMedia
geospatial information system (GIS) and
provides the user with a comprehensive
selection of intelligent compilation tools.
This powerful software environment allows
access to practically any geodatabase and
version of geospatial datasets. With this
software application, airborne, satellite and
UAS data are displayed in an intelligent GIS
environment with multiple, freely
configurable mono and/or stereo windows.
Same as the ImageStation® Stereo Display
(ISSD) with MicroStation, ISSG supports
viewing and editing of stereo images with

photogrammetrically accurate 3D-cursor
tracking. ISSG offers many practical tools for
the interactive acquisition and updating of
geospatial datasets. It enables the interactive
updating of 3D-object geometry and
attributes, as well as automatic attribution
and geometry validation. Geospatial data
generated in this way can be stored in an
open database format so that third parties
have seamless access to them through their
respective GIS systems.
The creation of digital surface models (DSM)
from optical stereo data is also part of the
functionalities, offered by the ImageStation®
suite. The software applications display
topographical data, both raster and vectorbased,
so well-structured that they are easy
to edit and efficient to use. With the help of a
'snap cursor', which snaps automatically to
the selected feature, a quick check of the
correct object selection is possible. Together
with the "Elevation" command, contour lines
are created interactively. To correct for the
individual depth perception of each operator,
vertical indexing is used to adjust and
thereby calibrate manual height
measurements.
Full performance by 3D-stereo visualization
Computationally intensive reconstruction
algorithms are responsible for the razorsharp,
three-dimensional generation and
display of geometric and georeferenced
models made up by dense point clouds. The
3D PluraView monitors from Schneider
Digital, the world's leading specialist for
stereoscopic 3D desktop visualization
solutions, provide the key to perfect
3D-stereo visualization for these professional
geospatial application areas. The beam
splitter technology meets the highest system
requirements in the areas of 4K displays, 3D
and VR/AR technology to display
geographical map material and highresolution
GIS data in perfect 3D-stereo
quality. The high brightness and contrast, full
resolution for each stereo channel thanks to
two screens and complete freedom from any
flickering effects, guarantee a perfect
3D-stereo experience and make it easier to
analyze and edit 3D content. The 3D
PluraView monitors render 3D objects clearly
visible even in darker image areas and are
free from blurring effects for rapidly moving
images thanks to a latency-free, fully
synchronous display of the two stereo
channels.
ImageStation® - certified for the 3D
PluraView monitors
As tried and tested technology for the past
17 years, the cutting-edge 3D-stereo displays
from Schneider Digital are 'plug & play'
certified for photogrammetry and GIS and
perfectly compatible with the ImageStation®
modules. The full compatibility of the
ImageStation® software with the 3D
PluraView monitor family has now been
officially certified by the manufacturer
Schneider Digital. The seal of certification
ensures that the combination of the 3D
PluraView hardware with the respective
software application meets the high
requirements of international standards in
terms of quality and workplace ergonomics.
For an optimal photogrammetric workflow,
the ImageStation® offers a fully integrated
software solution together with the
associated hardware components by
Schneider Digital. In addition to the 3D
PluraView monitor, these are powerful
workstations based on CPUs by Intel or AMD,
professional RTX graphic cards from NVIDIA
and Radeon Pro graphics cards from AMD,
and of course the Stealth 3D controllers. In
conjunction with the native implementation
of the stereoscopic mouse cursor in the
Hexagon ImageStation® suite, the Stealth 3D
controllers enable the spatial navigation to
3D objects, which can then precisely
measured and captured.
ImageStation stereo functions and display
tools - advantages for the 3D PluraView

MARINE SURVEY
Underwater expedition aims to unravel
mysteries of the Maldives
image courtesy
By Karla Cripps,
Think "Maldives" and the first images
that come to mind for many are rows
of overwater luxury villas jutting
out from long wooden docks, or gorgeous
beaches edged by stunningly white sands.
But in spite of the Maldives being one of the
world's most coveted places for a vacation,
not to mention a dream destination for scuba
divers, scientists say there's a lot they've yet
to learn about its underwater ecosystems.
Now, the Maldivian government and UK
marine research institute Nekton have
teamed up to unravel some of those
mysteries by launching an ambitious
expedition into the country's unexplored
waters.
The Nekton Maldives Mission, which launches
on September 4 and includes teams of
scientists from the Maldives and abroad,
plans to carry out extensive research below
30 meters using two high-tech submersibles
-- one of which can go as deep as 1,000
meters.
The aim is to help the Maldives manage the
impact of the global climate crisis.
"The Maldives is 99% ocean and just 1% land,
sitting on average 1.5 meters above the sea.
As a result, the nation faces a growing threat
from the rising seas," says a statement from
Nekton.
"But, armed with more knowledge of what
their waters contain, work can begin to
protect what lives there and safeguard the
environment those species inhabit, which
in turn makes the country better able to
withstand climate change."
The institute says 10 Maldivian marine
scientists have been selected as the first
"Maldivian Aquanauts" to lead over 30 first
descents in submersibles to explore the
country's deeps. The very first descent will be
led by an all-women team of aquanauts.
"We are determining the location, health
and resilience of our coral reefs, especially
the deeper ecosystems which we know very
little about, so that key habitats may be
identified for protection and management,"
said Maldivian team leader Shafiya Naeem,
director general of the Maldives Marine
Research Institute, in a statement.
"The reefs that surround our atolls help
reduce the impacts from sea level rise and
the increasing frequency and intensity of
storms, and forms the basis of our economies,
livelihoods and sustenance."
A 35-day mission
The RV Odyssey, an expedition ship, will carry
scientists from the Maldives, UK, India, and
South Africa on the 35-day mission through
the country's vast waters.

mapped, the researchers spontaneously decided
to visit yet another site that is located 6nm to the
east. Historic research indicates that the area
called Großklützhöved was used to scuttle entire
barges that were loaded with munitions. The
prospect of investigating a munitions-filled wreck
was exciting to everyone on board and when the
first wreck was visible in the data, the entire
group quickly gathered around the multibeam
station. During the course of the night, two
additional wrecks (one of which appeared to be
a sailing boat) were found. The next day, the two
sunken barges were explored using towed
TV-CTD with real-time video stream. One of
them capsized and lost its hazardous cargo
during sinking. In the darkness of the Baltic Sea,
a pile of grenade cartridges came into view of the
TV-CTD LED spots. The photo and video footage
combined with high resolution MBES led to a
more qualified estimate of the amount of
dumped munitions. For the planning of future
They will also "investigate the relative
abundance of the 40 shark and 18 ray species
at the apex of the food chain in the Maldives
ocean, which act as a critical indicator of
ocean health," it said in a statement.
Among the planned mapping operations is a
survey of a subsea mountain in the Northern
Indian Ocean.
According to Nekton, all samples and data
collected will remain the property of the
Maldives -- "a departure from some Westernled
science expeditions of the past."
Supporting sustainable tourism development
MARINE SURVEY
So what does all of this have to do with
tourism in the Maldives?
The country is made up of 26 atolls filled
with over 1,000 islands occupied by dozens
of resorts, all spread out over 90,000 square
kilometers. According to the World Bank, the
Maldives received over 1.3 million tourists
in 2021 -- about 80% of 2019 levels. Tourism
makes up around 28% of its GDP.
UXO remediation, it was essential to gain precise
knowledge about the number, location and types
of munitions.
During MineMoni-II, there was not enough time to
map the entire area of Großklützhöved, so the
researchers decided that they would come back in
2021 to finish the job. When ALKOR returned to
Kiel harbour, the team were able to look back at
two very successful weeks. More than 26km² had
been mapped to acquire high-resolution
multibeam data. Water samples were taken at 77
locations, which means that over 200 syringes
with exchanger resin are stored in the freezer,
waiting to be analysed with liquid chromatographymass
spectrometry. The AUVs ANTON and LUISE
went on 36 missions to acquire tens of thousands
of photographs and finally, 32 TV-CTD profiles
were filmed. It will take the researchers a year to
evaluate this massive amount of data. By then,
they will be ready to embark on MineMoni-III,
which is planned for October 2021.
Documenting the state of the country's waters
can support sustainable tourism development,
says a Nekton briefing on the mission: "The
health of the reefs is fundamental to the two
largest sectors of the Maldivian economy,
tourism and fisheries. Apart from the
economic benefit its coral reefs provide, they
are the first line of defense against waves and
storms, which are becoming more frequent
and intense."
Protecting the animal species that live there
is also vital, as it "results in a healthier ocean,
supporting sustainable fisheries and a growth
in tourism," says the mission briefing, which
notes that manta ray tourism alone generates
an estimated US$15 million annually in
revenue.

covering the 'Open Pit' is a 2,000meter long
magnetic anomaly directly overlain and
correlating to the previously announced highgrade
rock samples, which tested up to 46.6
g/t gold in the area known as the 'Open Pit'.
Terranet Limited is based in Accra, Ghana
and will be conducting the survey over the
32 July-August issue l 2022 www.africasurveyorsonline.com

GEOPHYSICAL SURVEY
Kukuom 'Open Pit' prospect. The field crew,
will be starting the survey mid-August which
covers an estimated area of 1.6 sq. kms,
with approx. 16.8-line kms of IP, employing
the pole-dipole array with a dipole spacing
of 25-meter using 8 dipoles. The Ground
Magnetics survey will cover approx. 40-
line kms. The survey is scheduled to take
approximately 6 weeks to complete, followed
by analysis and interpretation of the resulting
data.
For the past years Terranet has been involved
with acquiring, processing, interpreting, and
evaluating a wide range of airborne and
ground geophysical data throughout Ghana
and West Africa, using this information
for exploration purposes as well as in the
preparation of large- and small-scale maps,
from data capture (digitizing), structuring,
through to integration of processing and
interpretation.
The IP/resistivity and magnetic surveys
will be carried out across the area of
the 'Open Pit', extending East and West
of the favourable contact zones of the
metasedimentary and metavolcanic units that
hosts gold-quartz vein systems. The intent
of extensions beyond the contact zone is to
allow for deep penetration of the substrata,
up to 400 metre subsurface, and identify any
buried mineralization beneath the current 17-
hole, 150-metre proposed drill depth planned
for later this season.
Mr. Francis Lovebridge Agezo, Guskin Gold's
Director of Exploration, states 'The proposed
exploration program is designed to give us
a better understanding of the subsurface
gold mineralization. The purpose of the
geophysics is to fingerprint and characterize
zones of gold-bearing veins of suitable size
to allow for their possible mining. We believe
numerous zones may be identified and that
could provide sufficient material for mining
operations to begin, and hopefully continue
for many years to come.'
'A successful outcome will allow us geologic
confidence to define high-priority targets
for the upcoming drill program and our
work towards producing a mineral resource
recognized by international reporting
standards such as the Canadian NI 43-101 or
Australian JORC (2012).' Mrs. Naana Asante,
Guskin Gold's CEO, Director and Chairwoman,
affirms. 'We look forward to continuing to
release timely updates to our JV partners,
suppliers, government, and shareholders,
keeping everyone informed as we develop,
improve, and expand operations in Ghana.'
The Kukuom Gold Project Significance
Located in Asunafo South District, Ahafo
Region, and is a Joint Venture Partnership
with Danampco Company whereby Guskin
Gold has an exclusive seventy (70%) percent
interest.
The license area is 156 square kilometers
and the Kukuom Gold Project is highly
prospective, spatially related to major
mines including Newmont's Ahafo Gold
Mine (23Moz) located approximately 30km
north of the Kukuom property, and Asante
Gold's Chirano Gold Mine (5Moz) located
approximately 45km south-southeast of
Kukuom and their Bibiani Gold Mine (7Moz)
located approximately 25km southeast.
Francis Lovebridge Agezo, Guskin Gold's
Director of Exploration is credited as a
contributor to the discovery and development
of the Chirano Mine deposits. Notably on
April 25th, 2022, Kinross Gold Corp. (KGC)
announced the sale of the Chirano Gold Mine
for $225 Million to Canadian Asante Gold
(ASE); Asante having previously acquired
the Bibiani Gold Mine for $90 Million from
Australian Resolute Mining (RSG) in August
2021.

DRONES
Drones
Turkey's Bayraktar TB2 drone
Why African
states are
buying them
By Paul Melly
African states are increasingly
acquiring Turkish drones to fight
armed groups after they proved to be
effective in various conflicts around the world.
As Ukraine stepped up its initial fightback
against Russia's invasion, and long before
Western heavy artillery and rocket launchers
started to arrive, there was one weapon that
the Kyiv government could already deploy -
the Bayraktar TB2 drone.
This Turkish-made weapon had already
proved its effectiveness in helping Azerbaijan
defeat Armenian armoured forces and snatch
back extensive territory in the Nagorno-
Karabakh war of 2020.
But admirers of the drone's capabilities
are not confined to eastern Europe and the
Caucasus.
Recent weeks have seen a consignment of
Bayraktar TB2s delivered to the West African
state of Togo, which is struggling to curb the
infiltration of jihadist fighters moving south
from Burkina Faso.
While in May, Niger acquired half a dozen of
these versatile and affordable drones for its
military operations against insurgent groups
in the Sahel region south of the Sahara
Desert, and around Lake Chad.
Other African customers have included
Ethiopia, Morocco and Tunisia, while Angola
has also expressed interest.
But the first to use these potent surveillance
and strike weapons on the continent may well
have been the UN-recognised government
in Libya - where they were spotted as early
as 2019 and may have helped Tripoli's forces
hold off eastern rebels.
For African buyers, especially poorer countries,
drones provide the chance to develop
significant air power without the vast cost in
equipment and years of elite training required
to develop a conventional air strike force of
manned jets.
This is a particular attraction for states such
as Niger and Togo.
They face the complex challenge of curbing
highly motivated and mobile bands of
Islamist militants, camping out in the bush
and moving quickly through the scrubby
terrain of the Sahel by motorbike to stage
ambushes and surprise attacks on isolated
army and gendarmerie posts, border crossings
and civilian communities.
Security along the Togo-Burkina Faso border
is increasingly under threat from militant
Islamists Niger's army has been grappling
with this problem for years, fighting militants
in the tri-border region, where the country
meets Burkina Faso and Mali, just a few hours'
drive from the capital, Niamey.
Government troops are also engaged in an
arduous campaign to protect the far southeast
from attacks by Boko Haram and Islamic
State West Africa Province (Iswap).
But for Togo, the direct reality of the jihadist
threat is a relatively new and hugely worrying
experience.
For most of the past decade the activities
of the militant groups were confined to the
central Sahel - Mali, Burkina Faso and Niger
- and mainly in areas relatively distant from
their borders with coastal countries such as
Ivory Coast, Ghana, Togo and Benin.
But more recently the picture has begun to
change, as the armed groups extended their
reach across much of Burkina Faso, and into
rural areas along the border with these four
states.
By late 2019 security forces were detecting
signs of militant infiltration into northern
Togo.
Initially the fighters were just hiding out for
rest and recuperation, but the government
in Lomé, like its counterparts across coastal
West Africa, was already concerned that the
threat could grow.
Neighbouring Ivory Coast had suffered a
jihadist attack on the resort of Grand Bassam
in 2016, which left 19 dead, and then attacks
and clashes with security forces in the northeast
in 2020.
And a local wildlife guide died when militants
kidnapped two French tourists in the Pendjari
national park in Benin. Two French troops
were later killed in a firefight when the
34 July-August issue l 2022 www.africasurveyorsonline.com

DEFENCE
tourists were rescued across the border in
Burkina Faso.
The first direct raid on Togo itself, at
Sanloanga, came last November. Then before
dawn on 11 May, dozens of militants attacked
an army outpost at Kpék-pakandi, near
Burkina Faso, leaving eight soldiers dead and
13 wounded.
The troops fought back, killing some
assailants. The next month the government
decreed a state of emergency in Savanes,
Togo's northern-most region.
But that has not been enough to deter the
jihadists now operating in the frontier zone
and thought to be affiliated to Jama'a Nusrat
ul-Islam wa al-Muslimin, the main alliance
of Mali-based Islamist armed groups. Two
soldiers were killed in another incident in July.
President Faure Gnassingbé has toured the
area in an effort to bolster morale. But some
badly shaken locals have been abandoning
their villages - a phenomenon already seen in
other parts of the Sahel afflicted by militant
violence.
The regime used to monopolising power
for decades has even felt the need to invite
opposition parties for talks about developing
a united national strategy to cope with the
militant threat.
But ultimately, direct military force will have
to play a role. And that is where the Turkish
drones come in, providing Togo - like Niger
- with its own national aerial surveillance
capacity to try to spot bands of militant
fighters and, potentially, strike against them.
The use of drones is not new to the Sahel.
Both France and the US have drone bases
in Niger, operating in support of the
government's security strategy.
For larger powers such as Ethiopia - where
the federal government has been battling the
Tigray People's Liberation Front - drones are
a valuable tool for expanding overall military
capacity.
But there are risks, just as with manned
aircraft. By January, aid workers were
reporting that drones had killed more than
300 civilians in Ethiopia's Tigray conflict.
And the Togolese military have admitted
killing seven young civilians in error, after
an aircraft - whether manned or unmanned
is unclear - thought they were a group of
militants and launched a strike on 9-10 July.
The risks of such tragic mistakes are
heightened at moments of panic about the
apparent infiltration of jihadists.
For both Togo and Niger the supply
partnership with Turkey is also politically
useful, reducing their public reliance on close
security partnerships with France, the former
colonial power, about which a significant
strand of domestic opinion remains uneasy.
From Ankara's point of view there are also
attractions: "drone diplomacy" and military
partnership have become a significant
tool in President Recep Tayyip Erdogan's
foreign policy outreach south of the Sahara,
complementing more long-standing strengths
such as the building of airports and other key
infrastructure.
And within the Turkish politico-business elite
there is a personal connection too.
Baykar, the manufacturer of the Bayraktar
TB2 drone, is headed by two brothers - chief
executive Haluk Bayraktar and his brother
Selçuk, chief technology officer, who happens
to be married to President Erdogan's daughter
Sümeyye.

OIL & GAS
Study uncovers four
potential electrification
paths for oil & gas assets
By Melisa Cavcic
A
study, undertaken by the Net Zero
Technology Centre, the Cygnus
JV – comprising Neptune Energy
and Spirit Energy – and Sealand Projects Ltd
to assess potential routes for electrification
of oil and gas platforms, has found four
options to make this happen. However, the
commercial viability of electrification presents
a challenge.
The Net Zero Technology Centre, together
with the Cygnus JV and Sealand Projects
announced the findings of their Southern
North Sea – Oil & Gas Asset Electrification
Study on Thursday, explaining that this
explored the potential to electrify an offshore
platform with power from offshore wind,
using the Neptune-operated Cygnus complex
in the UK Southern North Sea as a case study.
The Cygnus field started its first gas
production in 2016 and it has a field life of
over 20 years. The field hosts two platforms
– Cygnus Alpha and Cygnus Bravo – and
the first one consists of three bridge-linked
platforms while the second one is an
unmanned satellite platform. The Cygnus
partners are Neptune Energy (operator, 38.75
per cent) and Spirit Energy (61.25 per cent).
Mungo McLeish, Director of Global
Operations and Electrification at Neptune
Energy, remarked: “We continue to explore
opportunities to reduce emissions as part of
our commitment to store more carbon than
is emitted by our operations and the use of
our sold products by 2030. Collaboration
across oil and gas and renewables sectors
can improve our understanding of the
opportunities and challenges associated with
the electrification of assets in the Southern
North Sea.”
According to these industry players, the Southern North Sea is home to numerous planned
and existing offshore wind farms, increasing the potential sources of power for platform
electrification. Therefore, there will be 6.8GW of wind power within 50 km of Cygnus by 2030,
increasing to 14.1GW within 100 km of the asset, making it a suitable case study for the
investigation of electrification using offshore wind.
Kenneth Cunningham, Senior project Engineer, Sealand Projects Limited, stated: “In seeking
to achieve industry decarbonisation targets, electrification of platforms has a key part to play.
Tying into a wind farm is an innovative opportunity which raises challenges, however, the
level of engagement across regulatory bodies and industry was hugely encouraging, and we
remain thankful for the support and advice. It is through this collaboration that electrification
opportunities, and ultimately the route to net-zero, can be delivered.”

OIL & GAS
As the North Sea Transition Deal (NSTD)
set a target to reduce offshore production
emissions by 50 per cent by 2030, the
majority of these emissions are a result of
power generation offshore from open cycle
gas turbines (OCGT), thus, providing this
power from offshore wind has the potential
to deliver a large portion of the emissions
savings targeted under the NSTD. Although,
“a significant challenge” in the commercial
viability of electrification remains based on
high CAPEX costs and direct impact on the
levelised cost of energy (LCOE).
Malcolm Offord, UK Government Minister
for Scotland, said: “The electrification of
offshore platforms will help to reduce
emissions and facilitate the transition of
the North Sea to a net-zero economy. With
its wealth of expertise and experience,
North East Scotland is leading the world
in decarbonising the energy industry while
bringing in new jobs and investment. The UK
government is investing £90 million in the
Net Zero Technology Centre to support this
and levelling up communities across Scotland
with more than £2 billion.”
Furthermore, four electrification options were identified during this study and an evaluation of
each was undertaken using the technical rather than the economic life of the asset. The four
examined options that offer a potential pathway to electrification include local offtake with a
power purchase agreement; local offtake with an offshore transmission owner; reallocation of
turbines; and dedicated offshore wind farms serving a platform.
Graeme Rogerson, Senior Project Manager, Net Zero Technology Centre, commented: “The size
of the prize is significant if we can establish a viable way to leverage the existing infrastructure
to supply power to offshore oil and gas assets. We have a number of barriers to overcome
including regulatory challenges and establishing a way to make one of the four proposed
options economically viable. However, the engagement levels from stakeholders have been
hugely promising and there is definite appetite to maximise the opportunity for electrification
of oil and gas assets.”

When it comes to the recent developments
related to the oil and gas production facilities
powered by wind, it is worth noting that an
oil and gas operator and a green energy and
infrastructure developer inked a new deal
last month, enabling the creation of one
of the UK’s first wind-powered oil and gas
production facilities.
As explained at the time, the provision
of wind power will remove up to 20,000
metric tonnes of CO2 emissions every year
from the offshore production facility and
demonstrate the use of floating offshore wind
in decarbonising oil and gas production.
