your solutionexecutive director’s reportJuly 2013 - Trenchless International8John HemphillIstt Executive Director@FollowTrenchlessInternationalon Twitter@TrenchlessIntThis year has been off to a faststart. Already in 2013, the ISTT, nationaland regional societies collectively haveheld trenchless conferences, trainingand other outreach programs coveringmany regions of the world. Just take alook at Chairman Samuel Ariaratnam’squarterly report to see the activitiesthat have been underway. These eventsare a proven means for promoting theuse of trenchless technologies for thepublic benefit. To strengthen an alreadysuccessful trenchless education andtraining program, the ISTT Board in late2012 launched the first ever TrenchlessPhoto Competition.The goal of the ISTT Trenchless PhotoCompetition is to establish a photo librarythat the ISTT can use to promote thetrenchless industry and the benefit oftrenchless applications. The photos willbe chosen through a competition andapproximately 100 photos will be selectedfor a Trenchless Technology photo album.The album will be a hard-copy, highqualitypublication of photographs withassociated descriptions that illustrate themany activities of the industry.As of the date of this report, the ISTThas received more than 150 photos from15 plus member societies covering anumber of trenchless technologies.Since my last report, Team LeaderDerek Choi and the Photo CompetitionTeam decided also to give each membersociety a page in the album for presentinga narrative historical description oftheir society’s programs and activities.Each member society page will includetwo-to -three photographs that, alongwith descriptions, will collectively painta picture of the evolution and growth oftrenchless worldwide, further enhancingthe educational value of the album.The ISTT is in the final stages of finalisingthe album. I encourage you to becomea sponsor of the photo album if youhave not already done so. Sponsorshipswill help fund the production cost ofthe album. There are two levels ofsponsorship – Corporate and Individual.The sponsorship application and otherinformation about the album are postedon the ISTT website at istt.comIt is planned to rollout the trenchlessphoto album at the 31st InternationalNo-Dig to be held on 1–4 September 2013in Sydney. As I noted in my April report,the Australasian Society for TrenchlessTechnology (ASTT) has put together afirst rate conference with over 50 highqualitypeer-reviewed technical papers.The exhibition will feature the latesttrenchless equipment.

Major CIPP contracts awardedAegion Corporation subsidiary Insituform Technologies US, LLC has been awarded two cured-in-place pipe contractsvalued at approximately $US10.4 million from the Metropolitan St. Louis Sewer District. The contracts are a part of MetropolitanSt. Louis Sewer District’s $US4.7 billion sewer system improvement program. This project includes the installation ofapproximately 47 miles of cured-in-place pipe (CIPP) in small and medium diameter sewer pipelines located in mostly residentialareas. Insituform will install CIPP using standard inversion methods as well as Insituform’s proprietary pull-in installation method,iPlus Infusion. Insituform will begin work on this project in August 2013 and is anticipated to complete the work within one year.Scottish pipe renewals in the bagScottish Water has completed the first phase of Scotland’s biggest watermainsrenewal project to date. When completed in April 2015, it will have covered4,300 km, stretching from Shetland to the Scottish Borders. The scheme, whichstarted in April 2010, has seen 2,924 km of pipes upgraded to meet strict waterquality standards and forms part of the Scottish Government’s wider £2.5 billionwater and waste services investment. The work has involved flushing, relining andreplacing watermains all over Scotland to ensure optimum water quality, reducedleakage and reduced likelihood of water pipe bursts.Concession contracts sold in MoroccoVeolia Environment has signed an agreement with global investment fund Actis, via its holding company Veolia Services àl’Environnement Maroc, to sell its Moroccan water, wastewater and electricity services, operated by concession companiesRedal and Amendis. The transaction will contribute around €370 million to the company’s divestment program.This withdrawal reflects Veolia Water’s decision to redirect its geographic focus and its growth strategy based on higheradded value solutions and activities. Finalisation of the transaction is subject to obtaining formal approval from the relevantpublic authorities and Moroccan government departments. Veolia has signed a three-year technical support contract with ActisNEWSJuly 2013 - Trenchless InternationalWatermains improvement for Northern IrelandNorthern Ireland Water is currently using Trenchless Technology toupgrade water supply infrastructure. The utility is involved in an ongoingprocess of improving and upgrading the water supply infrastructure in theCarrickfergus area as part of a £2.4 million program. Work will continue inthe area until August 2014. Once complete, the upgraded watermains willimprove the reliability and security of the local water supply, drinking waterquality and will also help reduce leakage. The project will also reduce thenumber of bursts in the area. Trenchless work has also recently commencedto upgrade the water supply infrastructure in the Greater Dungannon area.Once complete, this project will improve the reliability and security of the localwater supply, drinking water quality and will also help reduce leakage. Havingcommenced at the end of April 2013, the £2.7 million program will last forapproximately twelve months.Pipe Express product receives bauma Innovation Award 2013Herrenknecht’s Pipe Express innovation has been awarded the Innovation Award at bauma 2013 in the Machine category.Pipe Express is a complete new mechanised method for the near-surface installation of pipelines of up to 1,000 m in lengthand with diameters of 800–1,500 mm. A tunnel boring machine loosens the soil, which is then directly conveyed abovegroundusing a trenching unit. At the same time, the pipeline is installed underground. This method is unique for the installation ofpipelines with a diameter of up to 1,500 mm because the soil is directly removed and not pushed aside.The new minimal No-Dig method for installing pipe reduces environmental impact compared to traditional open-cutconstruction methods and also minimises costs. The development of the new system was funded by the German FederalMinistry of the Environment because of its environmentally friendly and cost-effective method of operation.12

Tunnels made in ManhattanThe East Side Access Project, which will connect the Long IslandRail Road’s Main and Port Washington lines in Queens, New York, toa new terminal beneath Grand Central Terminal, has been excavatingtunnels approximately 120 ft beneath Manhattan streets since 2006. Twotunnel boring machines (TBMs) were used in the project’s initial stages,manufactured by SELI and Robbins. The two TBMs in Manhattan madeeight successful tunnel drives.The project has thus far produced 5.6 miles of tunnels and the hugecaverns that will house the new station under Grand Central. The projectis progressing with excavation of an underground complex beneathGrand Central Terminal, and multiple slurry shield TBM drives in Queens.The $US7.5 billion project is the biggest addition to New York’s publictransportation system since the opening of Penn Station in 1910 andalso represents North America’s largest construction program. Whencomplete, 32,000 ft of new tunnels will have been excavated.HDD triumphs in demanding bore taskHorizontal directional drilling (HDD) has been used in Germany to connecta new sewer pressure pipe to a treatment plant 4.5 km away. The installationtook place near Bad Reichenhall, Germany, running partially along a tightfootpath, parallel to the river Saalach. A section of the pipe route could not beinstalled using open-cut methods due to an extremely tight passage adjacent tosteep rock walls bordering the footpath. Due to the rocky nature of the ground,a Tracto-Technik GRUNDODRILL 18ACS HDD machine, which is designed foralternating and difficult geological conditions, was used.

Inland PipeRehabilitation (IPR) installed its unique pressure pipe renewal system provided by RS Technik using Dow customformulated resins. With the development of the RS Technik System, combined with the cured-in-place pipe(CIPP) installation experience of IPR, watermains can now be relined and leaks can be repaired, before a linecompletely ruptures. In addition to industry approval, this unique fully structural solution is designed to sustainlong-term internal pressures and external loads of the existing pipeline. Unlike traditional CIPP, the RS Technikprocess includes a computer-controlled, mobile wet-out and mixing unit. This results in a faster response andconsistent higher quality, with professional installation.July 2013 - Trenchless InternationalAussie PM goes on-siteGHD welcomed Australian Prime Minister Julia Gillard to the official opening ceremony of the Great Eastern HighwayUpgrade Project, a project that represented one of the most significant service relocation and replacement challengeson a Western Australian infrastructure project. The project involved more than 80 km of services conduit includingwater, gas, power, telecommunications and drainage impacted. Adding to this challenge, the project was within aconstrained 21 hectare road corridor used by 55,000 vehicles per day. To mitigate potential risks, the project utilised3D modelling technology, called Services and Utilities Infrastructure Modelling, which is a first for major infrastructureprojects in Western Australia.Ms Gillard was joined at the opening by General Department of Transport Director Reece Waldock, Member ofthe Legislative Assembly Glenys Godfrey, and members of the City East Alliance Board, including GHD Manager forTransport Erik Geidans.Can’t wait for the next edition of Trenchless International?Get the latest news at trenchlessinternational.com/newsVERMEER.COMExpEriEncEd drill opErators work with a sEnsE of pridE.They know what they like.

View of Ville SansTranchée 2011 in Paris.Meet the society: FSTTFor 13 years, the French Society for Trenchless Technology has been steadily promoting the advantages ofTrenchless Technology, seeking to increase its prominence in the infrastructure, water and energy sectors in France.UNDER FRANCEJuly 2013 - Trenchless InternationalThe FSTT was created as an AffiliatedSociety of the ISTT on 4 July 1990, seekingto promote Trenchless Technology and toencourage clients, local authorities andproject managers to use these alternativetechniques wherever possible.French authorities were growingincreasingly aware of the need formaintenance, extension and renewal ofexisting water, energy or communicationnetworks. The society saw education asfundamental to achieving this goal andtherefore sought to provide an official trainingorganisation in Trenchless Technology forthe installation and maintenance of all typesof pipelines and underground networks.Key personnel behind the society’sestablishment include:• Michel Mermet: engineer, Roads andBridges, visionary Head of the Val deMarne Technical Department in chargeof water and wastewater. Mr Mermetbecame Chairman of the ISTT in 1993• Christian Legaz and Daniel Crosnier:engineers from the Val de Marne TechnicalDepartment• Mathieu Le Chatelier: forward-thinkingDirector of the contracting firmsMontcocol and Borie Michel Audouin,and highly determined Technical Directorof Ballot Contracting firm.Running the FSTTThe FSTT is headed by ChairmanPatrice Dupont, International DirectorJean-Marie Joussin and Scientific DirectorJean-Michel Bergue.John Hemphill and Dr Dec Downey from the ISTT with the FSTT’s Jean-Marie Joussin, at Ville SansTranchée 2009 in Paris.The society’s board members aresupported by Virginie Baffet in thesecretarial department and Monique Lacin the events department.To increase efficiency the FSTT hasset up a regional organisation with sixterritories in mainland France and two inoverseas departments.Delegates in mainland France are:• Rhône-Méditerranée-Corse: JacquesRaynaud and Jean-Christophe Behrens•• Artois-Picardie: local delegate tobe confirmed• Loire-Bretagne: local delegate to beconfirmed• Seine-Normandie: René-ClaudeFouilloux• Rhin-Meuse: Maurice Gerber• Adour-Garonne: Gérard LondosOverseas territories delegates:• FSTT/DOI (Indian Ocean): Michel Mermet• FSTT Guyane (South America):Thomas Cheron24

Collaborating with industryThe society works with many otherassociations and governmental organisationssuch as Canalisateurs de France (federationfor contractors involved in sewer, waterand other networks construction), AFG(French Gas Association), ASTEE (Scientificand Technical Association for Water andthe Environment), French water agencies,IREX (Institute for Applied Research andExperimentation in Civil Engineering), SNCF(French Railways), CSTB (French Scientificand Technical Centre for Construction) andthe French Ministry for Ecology, SustainableDevelopment and Energy.The society also maintains a partnershipwith the AFTES (French Tunnelling andUnderground Space Association), sharing acommon interest in the construction of manentry pipelines.The society is also actively involved inthe committees in charge of preparing newlaws for safety around gas pipelines, whichwere initiated by the French Governmentafter serious accidents occurred as aresult of unidentified gas pipelines. Aspart of this role dealing with accident andexplosion prevention, the society workswith contractors to identify existing buriednetworks, and to create guidelines andrequirements for construction close toexisting networks.Jean Michel Bergue Scientific Director and Jean Marie Joussin International Director at theInternational No-Dig Berlin ISTT Board of Directors meeting.politicians, decision makers, water agencies,consultants, contractors and suppliers.

In 2012 it was present at the6 th World Water Forum hosted by France andthe city of Marseille.As an approved training organisation,the FSTT provides a range of coursescovering Trenchless Technology, particularlyconstruction of trenchless works, trenchlessrehabilitation of sewage systems, drillingfluids, preliminary work investigations andthe new DT-DICT regulations (regulationswhich place a greater responsibility on thecontractor, not just the asset owner). TheFSTT also offers made-to-measure courses,such as one held in Reunion Island in 2011,which had more than ten participants.Every two years those involved inTrenchless Technology in France gatherat the ‘Ville Sans Tranchée’ (‘trenchlesscity’) show to attend live demonstrations,exchange experiences and get to know newequipment.In addition to this, each year the societyholds two regional No-Dig technical dayswith 300–600 attendees. These eventsinclude a show, approximately 20 exhibitors,and a technical conference focused onnational and regional issues. The show drawsThe trenchless climate in FranceThe recent Grenelle laws, which deal withenvironmental issues including the minimalasset management of sewer systems and anefficiency of at least 75 per cent for potablewater systems, hold the potential for thedevelopment of Trenchless Technology inthe water sector. The society is hopeful thatrelated opportunities will arise to promote thebenefits of a trenchless approach.Though currently Trenchless Technologyis not used a great deal in France, there areemerging sectors in which there is a lot ofpotential for the technology’s prominenceto grow. These include the energy sector,pipelines of large diameter for the gas market,burying of high voltage electrical lines for RTE(French Electricity Transport Company) andcoastal landfall for offshore wind farms.The water market is also a key sector inwhich the society hopes the influence ofTrenchless Technology will grow.There are several French national andregional events in the water and wastewatersector. The most important one is thebiannual Pollutec Lyon, an international showthat covers clean technologies for air, water,energy and sustainable development. Thesociety attended the event in 2012, setting upPatrice Dupont Chairman of FSTT at the 2011Ville Sans Tranchée opening ceremony.a ‘Trenchless Technology village’ with severalbooths and a conference corner, featuring17 technical and commercial presentations.Looking to the futureWhile only a few big microtunnelling jobswere launched during the last two years,the society expects that some significantmicrotunnelling and horizontal directionaldrilling jobs will emerge in the transportationand energy fields. There are currently anumber of small or medium sized renovationjobs, mainly for the sewerage market.In the water sector, the society has hadto face a lack of competitiveness with opencutmethods due to the economic crisis inEurope. In the current economic context theFSTT is focusing its efforts in promoting theadvantages of Trenchless Technology andthe cost-savings it can offer.Turn to page page 22 for afull preview of this year’s ‘VilleSans Tranchée event.DOWNUNDER1–4 SEPTEMBER 2013 | SYDNEY CONVENTION AND EXHIBITION CENTREThe conference program will feature acclaimed international experts on rehabilitation and installation, professionalswho have worked on recent large No-Dig projects the world over, and industry ‘think-tanks’.International speakers:• Australia• Canada• Colombia• Finland• Germany• Iran• Italy• Japan• Malaysia• The Netherlands• New Zealand• PolandLeading organisations including:• Sydney Water• The Washington Suburban Sanitary Commission• The National Chung-Hsing University Departmentof Civil Engineering• Russia• Singapore• Taiwan• Arizona State University• AECOM• GHD• And many more!Register online now to save $200 at nodigdownunder.com• Thailand• United Kingdom• United StatesTHREE-STREAMTECHNICAL PROGRAM70%InternationalspeakersBooking for several people within your organisation?

Saving the Seinethrough microtunnellingFrench company CSM Bessac has completed a microtunnelling project in the Paris region to assist inthe de-pollution of the Seine River.GET THEVERYBESTJOBUNDER FRANCEJuly 2013 - Trenchless InternationalUp until the beginning of 2010, thelargest diameter glass-reinforced pipes (GRP)pipes installed in France were 1,600 mm,which were primarily installed with the pipejacking method. However, the recentlycompleted rainwater collector and storageproject launched by the local authoritySyndicat d’Assainissement de la Boucle deSeine (union for the Sanitation of the Seine)was a national first in terms of pipeline size.The project involved installing 1,800 mm GRPHOBAS Jacking Pipes, and sets a precedentfor future trenchless undertakings with GRP.The project was part of a scheme tode-pollute the Seine River by limiting theamount of overflow caused by heavy rain.At the Place des Fêtes in Bezons, a fewkilometres outside of Paris, a rainwaterstorage basin has been constructed tohold 9,500 cubic m of water. Toulousebasedcompany CSM Bessac (subsidiary ofSoletanche Bachy and member of the VinciGroup) was contracted for the installation ofthe 380 m long transfer collector that will feedinto the storage basin at 1,800 mm pipe ata nominal flow of 5 cubic m per second.Installation face.We’ve created a dedicated jobs boardfor people in infrastructure.Our jobs board exclusively lists jobs ininfrastructure, which means you canfi nd the very best role that fi ts your skills,knowledge and passion.Visitwww.trenchlessinternational.com/jobsand find your job todayQualified.

Trenchless provesthe best solutionThe project was complex and demandingdue to the geological and hydrologicalconditions, as well as the pipeline route,which includes both a horizontal and avertical S-curve at a 900 m radius. Theproject required particularly meticulouspreliminary studies, which were conductedby the engineering office Cabinet Merlin.Further studies and calculations regardingthe construction works were carried out byCSM Bessac.Apart from minimising disturbance to theenvironment, the contractors opted for atrenchless solution because of the project’sgreat installation depth, groundwaterlevels and several existing structuresabove and around the pipeline route. Thepipeline was installed in 12–15 m depthand runs between a layer of limestone, alayer of alluvial deposits and around 10 mbeneath groundwater level. Furthermore, a4,000 mm diameter sewer main is one ofseveral obstacles in the route’s proximitythat needed to remain unharmed.UNDER FRANCEJuly 2013 - Trenchless InternationalSite of pipe installation on the Seine rainwater collector and storage project.Project dataYear of construction 2010Construction time 3 monthsTotal length 380 mDiameter 1,800 mmClientSyndicat d’Assainissement de la Boucle de SeineDesigner Cabinet MerlinContractor CSM BessacPipe manufacturer HOBASMinimised disturbances (noise, pollution, traffic) due toAdvantages installation method; totally watertight; long pushes due tohigh force tolerance; small radii.In deep waterThe jacking station was built inside the25 m diameter storage basin. Its thrustwall, which serves to provide a reactionagainst which to jack, incorporated aspecial slab leading back to the basinwall so as to transmit the 800 tonne loadsfrom the station to the basin’s structure.Groundwater posed a further challenge:lying at 10 m above the pipeline, it wasestimated to generate a load of almost30 tonnes on the boring head. This meantthat when the first pipes were jacked intoposition, the pipe string could be pushedback out while the jacking machine wasloaded with a new pipe. In order to preventthis, CSM Bessac designed an ingeniousnon-return system with two hydraulic jawsthat firmly gripped and held the pipes inposition.The 380 m S-curved route also poseda challenge to CSM Bessac and at thesame time gave GRP Jacking Pipes theopportunity to prove what they are made of.The 1,800 mm diameter, 3 m pipe sectionswere smoothly installed and their leak-tightflush couplings provided a tight line. GRPpipes accept high jacking forces equallingup to 800 tonnes and can be jacked aroundcurves down to 680 m radii without havingto adapt the force. This is possible due tothe material’s elasticity, which allows theforces to be evenly transferred from pipeto pipe over the entire wall-thickness of thepipe ends.Tunnelling under the Docksby Célia Franchin of Pfeiffer France, Guillaume Valade of HOBAS France, with the collaboration ofJulie Brossier of Semapa, Marie Hélène Dagras of Hydratec and Yves Sénéchal of Setec TPI.The Society for the Study of Control of Parisien Work and Development is co-ordinating six development projectsin Paris’ 13 th arrondissement. In a recent project, microtunnelling was utilised to install 2,000 mm insidediameter HOBAS GRP outfall pipeline on the Ivry dock in Paris, between the beltway and the Pont National.Part of the Society for the Study ofControl of Parisien Work and Development’s(SEMAPA) mandate involves redeveloping130 hectares in the ZAC Paris rive gauchearea to make room for housing, offices,commercial spaces, schools and otherprojects, including the projected extensionof Paris Metro’s Line10.Preparing to extend Metro Line 10To enhance the purity of rainwater enteringinto the Seine, a project took place in theBruneseau Nord that consisted of buildingstorage and treatment infrastructure forrainwater before it was discharged into theSeine. Now water is discharged either bygravity flow using DN 2,000 mm dischargepipes, or by overflow (using DN 500 mmpipes installed within the DN 2,000 mmpipes) when storm weather causes theSeine to flood.The water treatment project also includedconstruction of two supporting slurry wallsunder a beltway bridge, perpendicular to thepipelines, in preparation for the extension ofthe Metro’s Line 10.Microtunnel launch pit.Installing the outfall pipelineThe decision to use microtunnelling forthe installation was based on the highlyurbanisedarea the works would take placein, in addition to various technical work-siteconstraints. The high volume of traffic onthe Ivry dock meant the chosen techniquewould have to keep traffic disruption to aminimum. Additionally, the positioning of thedischarge shaft and water table level wouldmake open-cut installation dangerous; thesedimentation and discharge shafts werepositioned to allow the discharge pipelineUNDER FRANCEJuly 2013 - Trenchless International3031

to run below the Ivry dock at a depth of 8–10m over a distance of 205 m, and the watertable level fluctuates between 0–5 m.Building a 2,000 mm pipeline, a standarddimension for this type of project, with twohorizontal curves, one with a radius of 500 mand the other of 400 m, in addition to thealtimetric curve that would be used totransition from a 0.5 to a 1 per cent slope,it was decided microtunnelling would beable to carry out the project more safely andaccurately.Main contractorContractorSuppliersPipe supplierProject at a glanceSEMAPAHYDRATEC (agent)/ SETEC TPI/ TERRASOLSPIE BATIGNOLLES TPCI/ PARENGE/DGCPRESSPALI(slurry walls)/PFEIFFER MICROTUNNEL(microtunnelling)/SPIE (equipment)HOBAS FranceUNDER FRANCEJuly 2013 - Trenchless InternationalMicrotunnelling equipmentThe project is foremost a water treatmentproject, not a microtunnelling project.Therefore, the lamellar clarifier of the treatmentplant had to serve as the microtunnel boringmachine’s launch pit and the discharge shaftas the receiving pit. The dimensions of themicrotunnelling material and pipes had toconform to these constraints. GRP materialmet these specific project requirements.The selected pipes had a wall thickness of79 mm and an external diameter of 2,160 mm(ID 2,002 mm). An AVN1,600 full faceexcavation machine with an externaldiameter of 2,200 mm could be used insteadof an AVN2,000. The compact jacking frameof the AVN1,600 adapted perfectly to thereceiving pit.GRP pipes De2,160 are light-weight(1.13 t/m), which was a considerableadvantage for the project as they are easier tomanoeuvre. Due to its regular shape (outsidediameter tolerance of 1/1,000 th of the DN) andsmooth surface, the pipe has a particularlyhigh resistance to abrasion, thus allowing thelubrication of the inserted pipes to be kept toa minimum and jacking forces to remain low.A braking system was installed to regulate thepressure of the water table on the boring headand to prevent the pipes from backsliding intothe thrust pits at the onset of drilling.The boring head was adapted to the localgeology, which consists mostly of sandyand gravelly soil as well as some sectionsof clay, and to penetrate obstacles such asslurry walls. The wheel was equipped withroller cone bits and blades containing partiallyobstructed holes that limit soil entry.Crossing the slurry wallsFiberglass armatures were embedded intothe slurry walls in the microtunnelling machine’spath, as traditional metallic armatures wouldbe damaged by the machine.Plan of the microtunnelling project.Guidance system equipped with a theodolite.Exit shaftThe discharge shaft’s irregular dimensionsstem from the accumulation of manyconstraints. Because rainwater may not draininto the barge mooring areas, the shaft waswedged between the high-pressure gaspipeline (OD 600 mm) and the Pont National.Since the space available for the machine’segress was very limited, the company had todismantle the boring head before removingthe 28 t articulated shield. This was performedwith the help of a hoist that was small enoughto fit wholly within the worksite, but also hadthe capacity to lift the load virtually horizontallyunder the bridge. The extraction was a success.Guidance system for the curvesThe microtunnelling machine followedthe curved and counter-curved paththanks to the VMT SLS guidance system.The positions of the microtunnellingmachine’s target and of the referencepipe were established, and the referencepipe’s successive positions were thenused as reference points, thus enablingthe system to calculate subsequentpositions. A surveyor regularly confirmedthat the inserted pipes’ actual positioncorresponded to that calculated bythe system. This guidance system canestablish three-dimensional curves.The decision to use microtunnelling for the installation was based on the highly urbanised areathe works would take place in, in addition to various technical work-site constraints.Interior view of the 2,000 mm pipeline with a 400 m radius curve.Testing systemTo protect the public and preventdamaging existing infrastructure (roadsurface, gas pipelines, etc), a groundsettlement monitoring system was usedthat could detect even slightly abnormalmovements. Displacement tolerancelevels were 10 mm for road surfaces and5 mm for gas pipelines located 6 m abovethe discharge pipeline. The thresholdfor maximum vibrations established byGRTgaz was 50 mm/s. The testing systemwas tuned by zone according to the levelof risk. The first 50 m are the most criticalas the operator becomes familiar with theground conditions. This first zone wastested automatically at several points tothe right of the path, and several readingswere taken daily on the microtunnellingmachine’s zone of influence. The secondzone was monitored more lightly withdaily readings, and lastly, a buriedsettlement gauge and a vibration sensorwere installed near the gas pipeline. Themicrotunnelling machine’s passage causedno displacement greater than 2 mm, norany vibration in excess of 20 mm/s.Work-site in the foreground roads on theSeine dock on the left the gas station in thebackground, the beltway bridge.DrillingThe material and equipment’s installationrequired precise timing to coordinatepersonnel and pipe deliveries whileminimally impacting concurrent worksiteactivities.

Since then, the company has continued to utilise the trenchless drillingmethod for a variety of different crossings. Trenchless International takes a look at two recent largescaleprojects undertaken by the company.Reduced environmental impactThe HDD solution was chosen forthis crossing because of its reducedenvironmental impact, allowing the ownerto obtain the necessary environmentallicence to cross the river. Because ofthe peculiar nature of the limestone andclaystone substratum, the cleaning systemwas supplemented with centrifugationequipment working in parallel, in orderto separate the very fine materials fromthe drilling fluid. This allowed the drillingcontractor to optimise the circulation andminimise the volumes of fluid necessaryfor the works.Upon completion of the pipe pull,the same centrifugation equipmentwas then used in combination with aflocculation process, for final separationof the bentonite-based mud, with clearwater on one side and dry soils andclay on the other side. The environmentalimpact of the HDD solution was thereforeminimal, with practically no liquid waste atthe end of the works.HDD hits the mountainsHDI also recently completed a multiplecrossingsproject for high voltage linesat the foot of the Pyrenees mountains onthe border between France and Spain, aspart of a double 320 kV interconnectionbetween the two countries, integrated in theEuropean grid.The owner of the project was theconsortium INELFE, composed of theSpanish and French state electricityproviders. The main contractor was aconsortium between the Spanish contractorFerrovial and the French company Thepault.Drilling multiple crossingsfor high voltage linesThe HDD crossings at the foot of thePyrenees presented different challenges:48 crossings had to be drilled over a sixmonth period, with lengths ranging from80–745 m in variable soil conditions andcrossing under highways, railways andrivers. Three different compact spreads –DD8, DD10 and HK 100 – workedsimultaneously on the project.The project involved: detailed engineeringof all the crossings, procurement of the 250mm diameter HDPE casings, welding andremoval of any internal welding asperity,HDD works, and filling of the annulus with apurpose-made solidifying thermo grout.Control over installing the casing was achievedby using a video camera, providing theaccuracy required by the recent law coveringall underground networks in France.UNDER FRANCEJuly 2013 - Trenchless InternationalHorizontal Drilling International(HDI) has been a specialisedhorizontal directional drilling (HDD)contractor since October 1984 and isone of the longest operating contractorsin this industry. Based in Colombesnear Paris, the company operates bothinternationally and in its home country.HDD crosses the riverHDI recently completed a rivercrossing in a rock formation for a900 mm diameter gas pipeline nearBordeaux as part of the French gastransport network.The owner for this project was TIGF, aregional subsidiary of Total, one of the OilMajors. Prior to awarding the constructioncontract, considerable engineering andplanning was required to meet the client’senvironmental and safety concerns. Thecontract was awarded to pipeline specialistSICIM from Italy.Drilling in rock for a largediameter pipelineThe purpose of the project was to install a900 mm gas pipeline under ‘la Douze’ river,which is habitat to a protected species ofcrawfish. The soil formation was limestoneand claystone, overlayed by a layer of hardsandstone, with a top layer of recent alluvialsoils. The crossing was approximately 650 mlong and was executed with one of the250T HDI spreads. Two holes were drilledwith the use of mud motors and triconebits; the first hole received an 8 inch linefor fibre optic cables, and the second onewas reamed in three successive steps upto 48 inches (1,200 mm) with rock holeopeners. The 8 inch line was used duringthe reaming operations as a mud returnline, from pipe side to drill site, allowingcirculation and cleaning of the drilling fluidwhile drilling.HK 100 drilling under French canal.July 2013 - Trenchless International3435

HK 250 drill rig.Short term and long termadvantages of HDD solutionsThis high voltage line project at the foot ofthe Pyrenees has proven the versatility of HDDsolutions, in various soil conditions rangingfrom compact alluvial soils to sandstone andgranite rock, while preserving road and railtraffic or crossing deep river channels withminimal environmental impact. Additionally,as in this example, the environmental impactof HDD can be been further reduced with theuse of flocculation and centrifugation for thefinal treatment of residual drilling fluids.Much has happened since HDI first usedHDD to install a high voltage line in 1989.Electrical engineers and HDD contractorsmust give special consideration to the depthof the crossings and the spacing in betweentwo parallel lines, in order to account formagnetic and heating issues, but cablesinstalled by HDD continue to presentreduced maintenance costs and less riskthan aerial lines during extreme weatherconditions.UNDER FRANCESTATE OF INDUSTRYJuly 2013 - Trenchless InternationalGlobal state of theindustry report: Francecollated by Jean-Marie Joussin International Director FSTTThis is the third instalment of Trenchless International’s review on how the impacts of changingeconomic conditions have affected the trenchless industry over the previous three years.

Mr Theron says that the main challenge has been attempting to execute projects in allenvironmental and geological conditions with stricter constraints.Contracts in FranceAll types of contracts are used:private or public, open or not, built,design and build, design – buildand operate.The most common constructioncontracts (occasional engineeringand rare procurement) in HDD ormicrotunnelling are private or public,according to Mr Pellerin, “Contractsare generally lump-sum or permetre drilled as there are too fewsophisticated customers capable ofnegotiating contracts for complexwork in shared risks”.Bessac Managing Director Bernard Theron.STATE OF INDUSTRYJuly 2013 - Trenchless InternationalRecoveryThe industry experts agree that the2009–2012 period has been marked bya slowing of activity in France, similar tomany other regions of the world. Priceshave dropped and an increasing numberof international companies are bidding fortenders in France. Mr Pellerin notes thatby 2012 activity seems to be recovering.“The pressure is on the price level. Thereare still too few engineering companiesin France that are competent in HDDSade Directeur STS Philippe Brette.and able to make a proper technicalassessment of innovative trenchlesssolutions,” says Mr Pellerin.Although margins have decreased, mostFrench companies were careful in theirmanagement during this time and nonehave disappeared from the sector.Mr Brette says that more work needs tobe done promoting Trenchless Technologyas “the levels of price and profit aredecreasing, and the files of consultationscan be ‘locked up’ in the simplest and fastestmethod, without looking for alternative orrecommendation of No-Dig solutions”.Trenchless achievementsMajor achievements include some verysignificant technical successes. A selectionof the technical successes include:• HDD crossings over very long distances –beyond 3,000 m in one drill• Combining long distance and large pipediameter – 1,760 m of a DN1,200 inone drill• Drillings in very hard and abrasive rocks –hardness beyond 250 MPa, Cerchar > 5• Combinations of methods – for examplea retractable microtunnel followedby HDD – allowing the execution ofdrilled crossing works in very complexgeologies• Microtunnelling of sections of longerlengths – single drive of 875 m, outsidediameter 2 m• Completing sections of microtunnelledinstallation with curve and againstcurve.Challenges have been, and remain, thepressure on the sale price, due to regionalcompetition, sometimes exacerbated bythe equipment manufacturers, who oftendo not fully understand the technicalcomplexity of the projects they tender for.Mr Theron says that the main challengehas been attempting to execute projectsin all environmental and geologicalconditions with stricter constraints, suchas subsidence, nuisances, deadlines andprocess water treatment.An achievement of the sectorhas also been that the rehabilitationprocess reliability has been improvedby implementing technical assessments(French Avis Technique procedure) andstandards, imposing common designrules on projects.Overcoming obstaclesAs with other European industry expertssurveyed, in France the lack of technicalknowledge about Trenchless Technologyand lack of funding are cited as the mainchallenges holding back the adoption ofnew techniques.When asked how to overcomeobjections to trenchless works the expertsproscribed a range of solutions. Ownersand developers need to be targetedto improve technical education as they“are not familiar enough with trenchlessmethods and their field of application”.The actions of the FSTT such as technicaldays, the Ville sans Tranchee show,guidelines such as Microtunneling: fromdesign to tendering, allow the transmissionof knowledge.Future direction in the industryThe installation of large diameter gaspipelines and the extension of electricalnetworks presents a potential growth areafor the No-Dig industry. This includes gaspipelines of 48–56 inch diameter, buryingof high voltage electrical lines and coastallandfalls for offshore wind farms.Mr Brette adds that the recent Grenelle(multiparty debate and issuing of laws) onthe environment – including the minimalasset management of networks and anefficiency of at least 75 per cent of potablewater systems – appears like a goodopportunity for the future development ofthe trenchless industry.Improved engineering capabilities in thetrenchless field and legislative changeswill mean that trenchless works canHDI Managing Director Denis Pellerin.Pipe pull on a 32 inch HDD crossing by HDIunder a high-speed bullet train in south-westof France.“There are still too few engineering companies in France thatare competent in HDD and able to make a proper technicalassessment of innovative trenchless solutions.”HDI Managing Director Denis Pellerin.STATE OF INDUSTRYJuly 2013 - Trenchless International3839

increase in price competitiveness againsttraditional open-cut/destructive installationand repair works.Other areas of focus include:• Implementation of a recent law in Francecovering working condition constraintsbeside existing underground networks• Training and qualification of operators• Improvement of site waste managementincluding drilling fluids; volume reduction,final processing and treatment.The experts agree that TrenchlessTechnology will grow due to the benefits togovernments and communities.There is a clear advantage in terms ofenvironmental protection, carbon footprintand inconvenience to local residents.No-Dig also reduces the risks to theoperation of networks and has a high levelof safety during construction.Mr Pellerin says that short-term costeffectiveness can be achieved througha combination of several constructionmethods for smart technical solutions.While long-term cost effectiveness is areason to select No-Dig methodologiesfor the installation of high-voltage electricline or a pipeline installed by HDD, this willalso result in very low or much reducedmaintenance costs.How and when did you get into the trenchless industry?HDI (Horizontal Drilling International) entered the HDD business at the end of 1984with the first of four drilling rigs built in-house, offering 250 tonne pulling capacityand using the rack and pinions system that has since become the universalstandard of the industry. The company entered the microtunnelling sector in 2007.Initial HDD projects were completed in Bangladesh (1,450 m of 16 inch diameter)and Italy (480 m of 42 inch diameter) in 1985. The company’s first HDD project inFrance was in 1986.Bessac entered the trenchless industry in 1974. The main change has been, above all,due to the improvement of the reliability of machines and therefore the success of projects.There are practically no more technical failures and the limits of techniques have inceased.Sade STS started in 1985 by implementing cured-in-place pipe for non-man entrysewer rehabilitation. A suite of techniques – local repairing, close-fit relining forwatermains, bursting and others – came to complete the range of rehabilitationprocesses allowing the implementation of techniques best-adapted to the type ofnetwork damage. In 1989 the company completed its first microtunnelling job usingrented machines. In 1991 Sade STS purchased a MARKHAM Ø 500 and today theyhave a fleet of five machines covering the diameter range of 500–2,000 mm.Trenchless International would like to thank the FSTT, and particularlythe help of Jean-Marie Joussin, for the assistance and translationrequired in putting together this feature.GRUNDODRILL 18 ACS –the perfect solution fordemanding bore tasksPilot bore, the rock breaker has reached the target.STATE OF INDUSTRYJuly 2013 - Trenchless InternationalSeveral suburbs in the town of Unken in Schneizlreuth, Germany, needed a new sewer pressure pipeto connect to a treatment plant 4.5 km away. In order to cope with the more challenging aspect of theinstallation, a Tracto-Technik GRUNDODRILL 18ACS HDD was utilised.While most of the new sewerpressure pipeline could be installed usingtraditional open-cut techniques, the piperoute partially ran along a tight footpath,parallel to the river Saalach. Along part ofthe route, the installation work had to beinterrupted at an extremely tight passageadjacent to steep rock walls borderingthe footpath.The German government blocked theuse of open-cut installation at this sectionfor safety concerns due to the danger offalling rocks. The blocked area coveredan approximate length of 250 m. For thissection, the government recommendedusing horizontal directional drilling (HDD)to install the pipe.

of UCS 220 N/mm2, it was decided toutilise a Tracto-Technik GRUNDODRILL18ACS HDD machine. The machine isdesigned for use in alternating and difficultgeological conditions, and was thereforedeemed ideal for the bore.Between a rock and a hard placeThe width of this GRUNDODRILL rig,being only 2.3 m, proved to be a greatadvantage with the tight footpath thatwas only between 2.5 and 3 m wide.Because of the tight conditions, a supporttruck had to be set-up behind the drillingrig, causing some disturbance to theindividual working steps. Other than this,there were no other difficulties on thebore; path was closed to the public due towinter increasing the risk of falling rocks.For the drilling crew, this meant that safeworking needed special attention, as theground in the vicinity thawed during theday, causing minor stone falls.A low-maintenance rigAn advantage of the rig, comparedto other drilling rigs, is the relatively lowlevels of drilling fluid consumption. Inaddition, the water required to completethe bore was pumped out of the adjacentriver Saalach. This meant the drilling fluidwas always ready for use, without theusual time-consuming interruptions forpreparation, re-filling and transportation.The fluid, which had to be pumped outand disposed of, was less than usual.The bore path, which had to remainwithin the footpath width, ran through fillsoils that included rock. Several bendsin the footpath had to be negotiated.Therefore, before starting to bore, BorePlanner Software from Tracto-Technikwas used to precisely calculate theoptimum bending radius for each curve.After carrying out the pilot bore, whichwas undertaken using a 1.8 m longRockbreaker bit of 170 mm diameter,the most difficult part of the project hadbeen completed.

To ensure integrity of operations,a number of design and constructiondecisions were made. The pipe used forthe project ranges between 14–48 inchesin diameter, with wall thicknesses varyingfrom 7.1–30.2 mm, and was madefrom X52, X60, X65, and X70 steel. Thepipeline facilities included approximately150 block-valve stations and 19 pig-trapstations, as well as a fibre optic cable – forcommunication and control purposes –running the length of the lines.Construction in the environmentallysensitive areas was conducted in winter,when the land was frozen. The Sakhalin-2Project Basis of Design mandated thatspecial construction techniques beused to cross sensitive streams andother water courses. For this reason,Sakhalin Energy concentrated the choiceof crossing technique on the potentialimpact to salmon and the surroundingenvironment, and then ensured thatthe chosen crossing technique wouldmeet erosion and pipeline protectionrequirements.Six rivers were crossed using HDD, consisting of 12 individualHDDs between 500–1,000 m in length, for the 20 inch, 24 inch,and 48 inch pipelines.all the hazards to the integrity wouldbe identified. Although the hazards areknown, they require a considerableamount of work to mitigate: internal andexternal corrosion, pipeline overpressure,earthquakes, landslides, washouts, icescouring, undermining, vessels, illegal hottaps, and unintentional and intentionaldamage. A thorough HSE case ensuresan extensive program is in place tomanage those risks for the safety of theoverall operation.To deal with external corrosion,Sakhalin Energy’s pipeline has a cathodicprotection(CP) system installed, whichchanges the polarisation of pipe in theground. An unprotected pipe in theground would corrode; with the CPprojectsJuly 2013 - Trenchless InternationalHDD saves salmon in theTrans-Sakhalin pipeline systemThe Trans-Sakhalin pipeline system consists of 300 km of offshore and 1,600 km of onshore multiphase,oil and gas pipelines. As part of the Sakhalin-2 project, one of the world’s largest integratedoil and gas projects, horizontal directional drilling was used to minimise disruption in environmentallysensitive areas.Located in the far east of Russia,construction of the pipeline network startedin 2003, and it began operation in 2008. Itcarries oil and gas from two offshore fields(Piltun-Astokhskoye and Lunskoye) to thesouth, where Russia’s first LNG plant andoil export terminal are located.Project scopeChallenges connected with constructionof the pipeline in the harsh conditions ofSakhalin include:• Winter weather and an ice seasonthat lasts six to seven months with thetemperatures going down to -40°CThe Sakhalin-2 Project Basis of Design mandated that specialconstruction techniques be used to cross sensitive streams andother water courses.• more than 1,100 water bodiescrossings – over 150 of which arecritical for salmon spawning• 19 active fault crossings• 700 road crossings• 80 electrical transmission line crossings• Over 100 underground servicescrossings• Over 70 unstable ground areas(landslide, mudslides, avalanches)• Two major swamp areas• Lack of access in the middle of winterand during the spring thaw.Deciding on HDDDuring the engineering design phasefor the Sakhalin-2 system, variousconstruction methods were consideredfor river crossings. These includedopen trenching, elevated crossings andhorizontal directional drilling (HDD). Interms of environmental impact, HDDwas chosen as the optimal technique.Six rivers were crossed using HDD,consisting of 12 individual HDDs between500–1,000 m in length, for the 20 inch,24 inch, and 48 inch pipelines.For Sakhalin Energy and its pipelinemaintenance contractor Gazpromtransgaz Tomsk, the key would then besustaining integrity at the highest level.Sakhalin Energy Pipeline OperationsManager Bernie Trimmer says “Weare here to ensure that the integrity ofpressure envelope is maintained. To put itsimpler, oil comes in and goes out whereit should do, not in between. That’s whatwe’re here to do.”There were various risks identified atthe design stage and design solutionswere developed to mitigate them.These assumptions and decisions werethen routinely checked and monitoredto ensure their adequacy during theoperations stage.Managing the riskSakhalin Energy came up with anHSE case for its pipeline system whereDD-155TNEW Midsize Horizontal Directional Drill155,000 lbs.

To ensure safety of operations, the company has developed ‘crossing procedures’ whichdescribe the approach to approving, constructing, and monitoring third-party crossings ofits pipelines.The RELINE Groupenters the Asian marketprojectsJuly 2013 - Trenchless Internationalsystem, the polarisation can be changedand corrosion will be prevented. On topof that, the pipelines have a three-layeredcoating of the highest quality.To monitor internal corrosion, inputsfrom the three platforms and the onshoreprocessing facility are used. This detailedinformation allows the company specialiststo know what’s going on in the pipeline.Every ten days the onshore section ofthe system is cleaned of water andother sediments with pigs; the offshoresection undergoes this procedure on amonthly basis. On top of that, and toverify information, intelligent pigging isundertaken at the frequency establishedby the operation team but at least onceevery five years. Wall thicknesses andpipe movements are measured during thisoperation. In 2010, the baseline surveywas collected with intelligent pigging.“This is probably over and above thenorm for managing the pipeline integrity”Mr Trimmer says. “Generally you havepipelines laid in more stable soil than hereon Sakhalin.”With Sakhalin being a high seismicityzone it is important to ensure timelynotification and response in case of aseismic event. For that, Sakhalin Energyuses at least two sources of information:its own seismic monitoring system locatedalong the pipeline, and the USTA system.From that data every single incident isanalysed and then advice is given on thestrength of the event and the necessityto do anything further. Up to now, theseismic activity has been well below thethreshold when anything should be done,and there has been no effect at all fromthe seismic incidents that have occurred.Approximately 70 per cent ofpipeline incidents in the worldare caused by unintentionaldamage from human activity.As such, raising communityawareness about the pipeline isan integral part of operations.Fault crossings themselves aremonitored annually to see if there isany movement. Before the freezingtemperatures arrive, seismic faultcrossings are also checked for waterin the trench to make sure the backfillmaterial in the trench will not freeze andanchor the pipeline from movement.Monitoring of the pipeline is done notonly by looking at the computer controlsystem. Physical walkovers and helicopterflyovers are conducted regularly.“Back in 2010–2011, we did a top-walksurvey,” Mr Trimmer continues, “when weactually walked 800 km along the pipelinefrom north to south to check the pipelineright of way.”Along the pipeline there are five pipelinemaintenance depots (PMD) at carefullychosen locations based on the Russianlegislative requirement: in case of anoil spill, the company must be able tocontain it within four hours followingdetection. The depots are manned byGazprom transgaz Tomsk; each has anoil spill response (OSR) and transportationequipment, along with professional oilspill responders. The system’s routinemaintenance, surveys, and monitoring,are also undertaken from these depots.The biggest risk for SakhalinEnergy is transport. Approximately100–120 thousand km per month aretravelled in poor road conditions, androad transport safety is currently thebiggest focus area for the company. Agreat deal of attention is paid to makingsure that people who work and drive forthe company do so in a safe manner.Reinforcing design solutionsSakhalin continues to be a challengingarea to operate. In the summer of 2009three severe cyclones hit the island, oneafter another. River flooding was a typicalresult. However, in two cases it wasdiscovered that the river had changed itsroute, flowing down what used to be adry valley. That’s when the design issueswith the river crossings became obvious –changing of the river flow was not takeninto account.The work continued in two areas:reinforcing river bank protection at theimpacted rivers, and reviewing the rivercrossing data for more than 1,100 rivers.Additional efforts were undertaken tothen monitor risk areas and ensure timelywashout management.For that Sakhalin Energy continueslooking for the best available solutionsto ensure adequate monitoring of thepipeline’s integrity. A special monitoringsystem using fibre-optic cable that isplanned to be tested in 2013 is anexample of such solution. This will helpmonitor ground movement and groundvibrations, which may also happen due tothird-party interference. It is a challenge tomonitor the whole length of the pipelines,and physical events on the line, especiallythose connected with human activities,are difficult to monitor. This is particularlythe case in winter, with 3–4 m of snowand difficult access to the pipeline fromJanuary to April.The fibre-optic solution is similar tosonar and the way bats find their wayin the dark: a signal is sent down thecable and it comes back reflected fromthe pipe; after analysis, what is going onat any specific point of the pipe can bedefined.A strong assetmanagement strategyApproximately 70 per cent of pipelineincidents in the world are caused byunintentional damage from human activity.As such, raising community awarenessabout the pipeline is an integral part ofoperations. Sakhalin Energy has liaisonoffices along the pipeline route, with theinformation about the pipeline systemavailable in local community libraries.Local authorities, as well as all thecontractors and land users along thepipeline, are notified about restrictions onthe land use in the RoW, and the pipelinehas special markers showing the toll-freecontact phone number along its RoW.As offshore development on Sakhalincontinues, new operators come to theisland and construct their own pipelines.To ensure safety of operations, thecompany has developed ‘crossingprocedures’ which describe theapproach to approving, constructing, andmonitoring third-party crossings of itspipelines.RELINEEUROPE, the manufacturer of light cured liners for trenchless sewer rehabilitation, has expandedinternationally.

Pipe Jacking versus open-cutMicrotunnelling and Pipe jackingJuly 2013 - Trenchless InternationalUK-based Pipe Jacking Association has sponsored the development of software that estimates that pipejacking can reduce carbon emissions on infrastructure projects by up to 75 per cent in comparison toopen-cut methods.Digging up urban roads createsmassive carbon emissions compared to nondisruptivetunnelling solution. Now, savingsof up to 75 per cent in carbon emissionshave been demonstrated by a web-basedapplication – pipejackingco2calculator.com– which compares open-cut utility installationwith non-disruptive solutions, such as pipejacking or microtunnelling, for the installationof sewers and other utilities in urbanhighways. The comparison tool has beendeveloped on behalf of the Pipe JackingAssociation by TRL (Transport ResearchLaboratory), the international consultancythat provides research, consultancy, testingand certification for all aspects of transport.The Pipe Jacking Association representsmajor contractors and suppliers in thepipe jacking and microtunnelling industry.Pipe jacking, generally referred to insmaller diameters as microtunnelling, isa non-disruptive technique for installingunderground pipelines, ducts and culverts.Powerful hydraulic jacks are used to pushspecially designed pipes through theground behind a shield at the same time asexcavation is taking place.The 75 per cent saving in carbonemissions (>370 tonnes) was achievedby comparing the installation of 500 mof 600 mm pipeline, 6 m deep, usingnon-disruptive techniques with open-cutconstruction. Additionally, the constructionperiod for the trenchless installation wasprojected to be less than half that of theopen-cut construction. At shallower depthscarbon savings are typically in the range of50–60 per cent.The free and easy to use carbon dioxideemissions calculator, that in secondscan produce indications of comparativeemissions, has been verified by WRc plc, anindependent research-based consultancythat provides sustainable solutions for theprotection, enhancement and maintenanceof the natural environment.TRL’s project manager, MatthewWayman commented: “The findingsshould encourage water and other utilitiesto consider pipe jacking and other nondisruptivetrenchless techniques whenappraising new utility installations.”The application enables the userto identify more carbon (and energy)efficient options, and can thereforeassist them to meet reduction targetsestablished as a result of applying carbonregulations or other voluntary guidance,including the Department of Energy andRoad works related congestion is estimated to cost the UK economyaround £4 billion a year. Successive governments and London mayorshave expressed concern and attempted to control the disruptioncaused by utility companies and in early 2012 the Governmentannounced enhancements to the New Roads and Street Works Actenabling local authorities to charge utility companies up to £2,500per day for digging up busy roads at peak times (lane rental). Apartfrom carbon savings and the disruption costs, open-cut constructionfollowed by re-instatement is estimated to reduce highway life by upto 30 per cent, representing a substantial additional community costfor highway authorities. It is hoped that lane rental charges, togetherwith readily available evidence of carbon savings, and the communitycost of highway degradation occasioned by open-cut installationwill encourage utilities to adopt non-disruptive trenchless optionswherever and whenever possible.Climate Change’s CRC Energy EfficiencyScheme (formerly Carbon ReductionCommitment), or other independentlyinitiated key performance indicators.Data for the calculator has beendrawn from a number of authoritativesources that include the Universityof Bath’s Inventory of Carbon andEnergy for construction materials, theConcrete Pipeline Systems Association,and outputs from the Department forTransport’s QUADRO program (Queuesand Delays at Road works) developed byTRL. Reports can readily be producedthat not only provide comparativeemissions data for open-cut and nondisruptiveoptions, they also detail datasources and assumptions utilised in thecalculations. Further options are availableto input detailed additional data as aproject progresses.Microtunnelling and Pipe jackingJuly 2013 - Trenchless International4849

We have to stop beginning cheap and ending expensive.Premier of Baden-Württemberg, Winfried KretschmannMicrotunnelling and Pipe jackingPremier of Baden-Württemberggets behind tunnellingIn the town Schwanau in South Germany, Premier of Baden-Württemberg Winfried Kretschmann visitedtunnel boring machine manufacturer Herrenknecht and expressed his enthusiasm for supportingtrenchless technologies and taking an innovative approach to civil construction works.BADENWÜRTTEMBERGSchwanauand the technology, not just about profit.”Discussing the topical subject ofStuttgart 21, Mr Kretschmann stressedthat it was important to him to work withcivic society for projects such as this,not against it. Projects needed to beproperly planned.“We have to stop beginning cheap andending expensive,” said Mr Kretschmann.For this reason he also supported MrHerrenknecht’s call for the constructionof railway tunnels to be tenderedwithout prior commitment to a specificconstruction method.Mr Kretschmann said “We need to beopen with regard to technology – that waythe technically best and most economicalsolution is the one that is chosen.”To date, Deutsche Bahn has alwayscommitted itself to a particular technicalmethod at the time of tendering.Speaking on geothermal energy,host of the tour, Mr Herrenknecht,said “Geothermal energy can and mustmake an important contribution for theenergy transition.” However, he saysthis transition also requires appropriatepolitical support.Premier Kretschmann at Herrenknecht: Dr Martin Herrenknecht, Chairman of the Board of Management(second from the left) showed the Premier of Baden-Württemberg, Winfried Kretschmann (third fromthe left), around the headquarters of the tunnel boring machine producer in Schwanau.“In Baden-Württemberg, geothermalenergy offers great opportunitiesin the long-term, in particular for thesupply of heat,” said Mr Kretschmann.Currently the Herrenknecht deep drillingrig ‘InnovaRig’ is being used in Brühlfor up to 4,000 m deep drilling for ageothermal power station.Microtunnelling and Pipe jackingJuly 2013 - Trenchless International“Visiting businesses in Baden-Württemberg is an important part of mywork.

Recommendations for thechoice of an adequate bentoniteSuspension for lubrication in pipe jackingby Britta Schoesser 1 , Steffen Praetorius 2 , Markus Thewes 1 , Marc Peters 2Microtunnelling and Pipe jackingJuly 2013 - Trenchless InternationalDuring pipe jacking it is essentialto avoid downtimes, increased jackingforces and delays due to high skin frictionon the surface of the pipe string. Thiscan be realised by injecting a bentonitesuspension, which is adjusted to thegeotechnical characteristics of theground, in the annular gap. An optimisedlubricant in combination with the righttechnical equipment, e.g. an automaticlubrication system, minimises the riskpotential of the pipe jacking project andincreases the accessible jacking lengthat the same time. Thus possible savingsconcerning the overall jacking time andcosts can be generated.In contrast to the face support forhydro-shield tunnelling, where designguidelines for the choice of theappropriate bentonite suspension exist,no general recommendations for pipejacking projects have been developedyet. This is the starting point for theco-operation of Herrenknecht AG with theInstitute of Tunnelling and ConstructionManagement of the Ruhr-UniversitaetBochum to develop a practical guideline.At first, the relevant geologicalproperties of soil and rock are clearlysummarised and their influences onthe requirements for the bentonitesuspension are explained. Concerningthe two scopes ‘stabilisation of thesurrounding soil’ and ‘lubrication’, thebentonite suspension has to fulfil certainstandards to the specific parameters,e.g. yield point, viscosity and gelstrength. These relations are presentedin the guideline and the test methods tocontrol and determine the parameterson the construction site are explained.Furthermore, recommendations toachieve a high quality suspension aregiven, e.g. range of pH-value, waterquality, periods for agitation and swellingof the slurry. On the one hand it is the aimof the guideline to support the planningand application of optimised lubricationin pipe jacking and on the other hand toprovide a reliable tool for contractors andconsulting engineers.IntroductionWhile pipe jacking, prefabricated pipesare jacked from a starting shaft throughthe subsoil to a target shaft by meansof a jacking station. The in-situ soilis excavated at the working face bythe jacking machine and dischargedhydraulically, pneumatically or by screwconveyors. In general, pipe jacking isrealised in a range of diameter between1.2 m and 4.5 m in cohesive and noncohesivesoft soil as well as in hard rockwith or without groundwater or seepagewater, respectively. The jacking forceapplied by the jacking station has toexceed the penetration resistance atthe cutting head of the TBM and thetotal frictional resistance of the jackingmachine and the pipe string (skin friction).According to figure 1, the amount of thepenetration resistance in homogeneousground conditions is nearly constant overthe jacking alignment, while the frictionalresistance is increasing with increasingjacking length.In order to keep the jacking force aslow as possible, appropriate measuresare necessary to reduce the frictionalresistance, e.g. cutting of an annular gapcombined with the injection of lubricantsinto this annular gap. The frictionalresistance (skin friction) is decreasedeffectively by the following effects(Schoesser, 2004):• Reduction of the radial stress onthe surface of the jacking pipesby maintaining the annulargap(stabilisation of the ground with theeffect that the surrounding subsoildoes not transfer the earth pressure tothe total circumference of the jackingpipe).• Reduction of the friction coefficientμ between the surface of the jackingpipes and the subsoil by means of alubrication layer.The choice of an appropriate bentonitesuspension to be used as a lubricantdepends on the characteristics of theground. In the guideline, the fundamentalproperties of soft soil and hard rock aresummarised, in doing so the focus isbased on the stability and the cavity sizeof the ground.On the other hand, the specificparameters of the bentonite suspension,such as the size of the suspendedbentonite particles, the yield point,viscosity and gel strength, are described.Function of the bentonitesuspension in the annular gapBy adjusting the annular gap, variablereactions in the ground have to beexpected in reference to the stabilityof the subsoil. In stable ground, theexcavated borehole maintains stabilityand the contact area between jackingpipe and surrounding soil is limited to acertain part of the pipe circumferencee.g. the pipe’s invert. In this case, theinjected bentonite suspension operatesas a lubricant in the annular gap. Thefriction coefficient μ between the surfaceof the pipe string and the subsoil isdecreased effectively whereas the jackingforce is reduced. In order to build up1Institute for Tunnelling, Pipeline Construction and Construction Management, Ruhr-Universitaet Bochum, Bochum, GERMANY2Business Unit Utility Tunnelling, Herrenknecht AG, Schwanau, GERMANYFigure 1. Jacking resistance in pipe jacking (Herrenknecht AG).In order to keep the jacking force as low as possible, appropriate measures are necessary toreduce the frictional resistance, e.g. cutting of an annular gap combined with the injection oflubricants into this annular gap.a lubrication layer, the lubricant hasto fill the annular gap completely andmay not flow uncontrolled into theground. Determining parameters are thepermeability of the subsoil and the abilityof the lubricant to limit the penetrationdepth into the ground. In unstableground, the excavated bore hole willcollapse above the pipe string and coverthe pipe’s circumference. Here, the abilityof the bentonite suspension is importantin order to stabilise the surrounding soiland to remain the annular gap open. Thebentonite suspension must interact withinthe unstable ground in order to conveythe difference out of the suspensionpressure in the annular gap and the earthpressure to the particle structure of thesubsoil.Certain circumstances can require athird function of the bentonite suspensionin hard rock. In fractured rock singleparticles fall during the jacking processout of the rock mass of the borehole.These particles have the tendency togather in the annular gap and, in theworst case, induce the pipe string toget stuck. This scenario also can beprevented by the injection of a bentonitesuspension in the annular gap, which isable to carry the particles and avoid theassembly.Therefore, the specific tasks of abentonite suspension in the annular gaphave to be differentiated in the functions:• Stabilisation of the surrounding ground• Lubrication of the pipe string• Carrying of ground particles.In reference to the specific geotechnicalconditions on a construction site, differentfunctions of the bentonite suspensionwill be used. In general, the followingboundary conditions represent the basicsfor an effective lubrication in pipe jacking:• A sufficient amount of the lubricantis injected into the annular gapand remains there. There is nopossibility to change or to adjust thespecific parameters of the bentonitesuspension subsequently.• There exists no closed loop for thesuspension. The possibilities to checkthe impact of the suspension in theannular gap and the subsoil directlyare very extensive. The effect oflubrication can only be evaluated bythe increase or the decrease of thejacking force with certain time.This is an edited excerpt. For the full paper and references please see the original.• Due to the fact that a standard pipejacking takes several weeks or monthsand the pipe string is in motion duringthis period, time effects concerning thealteration of the suspension consistencyand the flow behavior of the suspensioninto the subsoil have to be taken intoaccount. In general, the flow of thebenonite suspension in the annular gapis spatially restricted.SummaryThe adjustment of the bentonitesuspension in order to stabilise thesurrounding ground and to lubricate thepipe string in the annular gap consists offollowing steps:1. Assignment of the main function of thebentonite suspension in the annulargap in reference to the stability of thesubsoil.2. Determination of the cavity size in thesubsoil.3. Selection or calculation of the minimumyield point or calculation of the yield pointin reference to the penetration depth intothe subsoil required amount of bentonitefor mixing the suspension in reference tothe chosen bentonite product.Microtunnelling and Pipe jackingJuly 2013 - Trenchless International5253

The additionalclass would be under construction classes,specialist works.The trenchless designation was proposedto be described as “the development,extension, installation, repair, renewal,renovation, alteration, maintenance orassessment of underground conduits,pipelines, ducts and sleeves, using trenchlesstechnologies for the construction andrehabilitation of infrastructure and services”.It was resolved to seek comments fromall the members of SASTT first, to assessthe preference and need for the newclassification of construction work.South African company takes out2012 ISTT No-Dig AwardSouth African company TrenchlessTechnologies was awarded the ISTTNo-Dig Award in the Project category atthe International No-Dig 2012 conferencein Sao Paulo, Brazil for its project ‘PortElizabeth goes trenchless’.A team managed by TrenchlessTechnologies undertook the rehabilitationof two parallel sewers located in the heartof Port Elizabeth’s business district inSouth Africa. Originally intending to usespiral wound techniques throughout theproject, the team soon discovered that siteconditions also required the use of curedin-placepipe (CIPP) and pipe bursting atcertain locations.Altogether, the project used five differenttrenchless techniques – spiral woundexpanded to a close NoDig fit, spiral woundin-place, ambient cured-in-place pipe, UVcured-in-place pipe and pipe bursting –to successfully complete the project. Thisproject is an excellent example of usingTrenchless Technology options to addressunanticipated site conditions, allowingthe project to be completed successfullywithout excavation and surface disruption.SASTT award of excellence for2012: award ceremonyAt the SASTT annual general meeting inFebruary 2013, the Chairman announcedthat the SASTT Award of Excellence for 2012had been bestowed upon the upgrading andreplacement of sewers in Alexandra (Phase 3).The chairman presented the awardcertificate to:• Tawanda Mashababe of JohannesburgWater (SOC) Limited• Abe Thela of Nyeleti Consulting (Pty) Ltd;and• André Germs of Insitu-Pipelines (Pty) Ltd.Visit theNSTT No Dig Event3 & 4 october 2013 Expo HaarlemmermeerThe Netherlands• Two days devoted entirely to the subject oftrenchless technology!• Trade show with demonstrations• Meet top industry representatives• Walk-in theater for informative workshopson drilling and relining• NSTT No Dig Award 2013 ceremony onOctober 3 at 4 p.m.Participating:N e l i s I n f r a A a r s l e f f J VAccess to the trade show, workshops and Award ceremony are free.It is however necessary to register in advance via www.no-dig-event.nlOn October 3. there is also a Conference.

ROUGHNECK takes on rockCarbon reduction in the pipelineHammerHead has launched the new ROUGHNECK R400 Pneumatic Rock Hammer System for theunderground construction industry.HOBAS Australia is actively minimising its carbon footprint by taking part in the Carbon ReductionInstitute’s (NoCO 2) Certification program and offering carbon-neutral pipes.COMPANY NEWSJuly 2013 - Trenchless InternationalThe system, which is designed todrill at rates up to 150 ft per hour whileproviding enhanced steering performance,includes the R400 air hammer, 5.25 inchstraight and offset bits, patent-pendingpull-back kit, control station/oiler, drillconversion kit and universal horizontaldrilling (HD) high-flow rock drill housing.Designed to work with the new HDuniversal high-flow rock drill housing, theROUGHNECK R400 allows a directionaldrill to work in almost any rock conditionwithout changing the housing. Thishousing supports the rock hammerby increasing the air distributed to theinternal piston. The larger bore diameterof the housing makes the ROUGHNECKhammer run at maximum efficiency,delivering a harder blow at faster impact.The patented, offset rock bit designprovides precise steering, allowing theoperator to navigate a wide variety ofground conditions. Integrated facecleaningexhaust ports help preventplugging of the hammer to allow forreliable performance, and the patentedcheck valve located within the biteliminates ingestion of debris.Available for any drill, the ROUGHNECKcontrol station can be installed with a teeand a ball valve on the high pressure sideof the mud pump. This feature provides apath for the airflow to be directed into thedrilling fluid supply line. The control stationutilises the drill’s existing mud pump toefficiently deliver air, oil and fluids downhole, reducing the footprint and weight.INTERNATIONALROUGHNECK rock hammer control station/oiler and remote operator station.Integrated electronics facilitate the drillingoperation and provide the operatorwith control and increased productivity,without leaving the drill operator’s station.The new system also continuesHammerHead’s tradition of designing easeof maintenance into its products. Almost25 years ago, the company pioneeredthe development of an easy-to-servicepiercing tool that significantly reducedthe time needed to maintain it. The newROUGHNECK system is equipped withpatented spanner wrench holes in thefront and rear of the hammer, reducingthe number of breakout jaws required forchanging out the bit or servicing the tool.The ROUGHNECK R400 rock hammersystem is available from HammerHeadTrenchless Equipment or from authoriseddealers worldwide.HammerHead, an Earth Tool Companyof Oconomowoc, Wisconsin, US,manufactures a full line of pipe bursting,pipe ramming/HDD Assist, pneumaticboring equipment and HDD tooling andaccessories.For more information visithammerheadtrenchless.com.Sydney Convention and Exhibition Centre1–4 September 2013ISTT 31 st International No-DigASTT 10 th National Conference and Exhibitionnodigdownunder.comDespite not being subject to the newcarbon tax the government introduced forlarge CO 2emitters in July 2012, HOBAS isoffering carbon-neutral HOBAS pipes as acertified ‘low carbon’ company in its aim toaddress climate change.HOBAS Australia’s Andrew Holmansaid “We assessed the carbon footprint ofHOBAS pipes by means of a greenhousegas emissions analysis, which was verifiedby the Australian Carbon ReductionInstitute. Through the Institute’s NoCO 2Certification program, we are measuring,reducing and offsetting our climate changeimpacts through a variety of carbon offsetprograms.”The carbon footprint study was conductedby the principles included in PAS 2050:2011 –a publicly available specification originallypublished in 2008 as the world’s firstframework methodology for productcarbon footprinting. This is built upon ISO14040/44 standards and provides a methodfor assessing the lifecycle greenhouse gasemissions of goods and services.
