Funding AvailableCarbon Trust LaunchesTechnical Challenge

The Carbon Trust launched a global competition to findworld-leading solutions to the problem of transferringengineers and equipment safely from boats to wind tur-bines as far as 300km offshore in 3m wave heights. Theproject aims to improve the economics of offshore wind byboosting revenues by as much as £3bn at a crucial time forthe next generation of Round 3 offshore wind farms. Thecompetition aims to generate at least a 4% increase in tur-bine availability through the development of new tech-nologies for the most challenging sea conditions. This inturn could increase the power generated, which wouldmean saving £3bn of lost revenue. This improvement inavailability would also save an extra 1.3 Mt CO2 per year.

The next generation of ‘Round 3’ offshore wind farms tobe constructed from 2014 will consist of up to 1,500 tur-bines, located up to 300 km offshore. By enabling safetransfer to a turbine in 3m waves through the develop-ment of new systems, the increased potential for mainte-nance will improve availability.

The competition is part of the Carbon Trust’s OffshoreWind Accelerator, a major industry collaboration witheight leading energy companies – DONG Energy, E.ON,Mainstream Renewable Power, RWE Innogy,ScottishPower Renewables, SSE Renewables, Statkraft andStatoil – which aims to drive down the costs of energyfrom offshore wind by 10%.

This latest OWA global competition aims to identify anddevelop the necessary technologies for access of far-off-shore wind turbines, focusing on:• Transfer systems• Vessels • Launch and recovery systems

The successful applicants to the competition will benefitfrom funding of up to £100,000 per concept to supportthe design and development of the successful concepts; theopportunity to work with eight leading offshore winddevelopers with licences to develop 30GW of offshorewind capacity in UK waters (representing 60% of today’slicensed UK capacity) and potentially several millionpounds of funding to take the concepts to full-scaledemonstration. The competition is supported byRenewableUK, IMarEST, RINA, SMI & EWEA.Companies interested can submit their designs until5pm, November 26, 2010, by visiting

As this edition was going to press the ObamaAdministration announced the lifting of its contro-versial deepwater and natural gas drilling moratori-

um, though it is widely expected to take several additionalweeks to get back to business as usual. While the lifting ofthe moratorium comes about six weeks earlier than expect-ed — perhaps coincidentally in step with mid-term electionsin the U.S. — there are still many questions as to the breadth and depth that theDeepwater Horizon spill will have on the business of offshore energy discovery andrecovery, this generation and next.

I am pleased to welcome to this edition of MTR the insights of Jonathan K.Waldron of Blank Rome LLP. Waldron is a long-time contributor to MTR sister-publication Maritime Reporter & Engineering News, and starting on page 24 he deliv-ers thoughts on “What’s Next” in the aftermath of the worst oil spill in the historyof the U.S.

The only certainties are that change is imminent and that our business, the busi-ness of working more safely, efficiently and cost-effectively under the water — some-times very deep under the water — will be called on increasingly to deliver the tech-nologies and techniques to ensure that the chance for a repeat of the DeepwaterHorizon is mitigated as much as possible. Having just returned from a successfulOceans conference and exhibition in Seattle, and having the opportunity to chat onthe sidelines with a number of colleagues from the oil majors, it is a safe bet toassume that no one wants to see their uncontrollable oil well spewing 24/7 on majormedia outlet’s web portals.

Hawkes Remotes Inc. (HRI) announced itsinitial product lineup, a family of threeROVs which incorporates new proprietaryfiber-optic tether technology and high ener-gy-density batteries to enable range, depth,and deployment capabilities well beyondthose of current-generation ROVs. HRI’sROVs will leverage its new SpiderOptic tech-nology, which uses thin armored fiber-optictethers that pay out as the vehicles move,reducing drag, improving performance, andeliminating the need for cumbersome ship-based support infrastructure. HRI’sSpiderOptic cartridge systems will be avail-able in single-use (disposable) and reusableconfigurations, and are designed to be easilyand quickly swappable in the field. In addi-tion, all HRI vehicles will be made availablefor full ocean depth, building on a suite oftested components developed for theChallenger manned deep sea submersible.

“SpiderOptic technology fundamentallychanges the way ROVs move through thewater,” said Graham Hawkes, the company’sChief Technology Officer and Co-Founder.“By using thin tethers deployed directly fromthe vehicle, we will fundamentally alter the

performance and efficiency of deep sea andlong range deployments. This technologyalso gives HRI’s ROVs a decided advantagein portability, enabling rapid responsedeployments and utilization from smallerships of opportunity.”

“When you look at the cost of ROV oper-ations, it’s driven primarily by the ship costs,not the actual ROV cost,” said JonathanEpstein, the company’s CEO and Co-Founder. “Moreover, the capital cost forstandard ROVs capable of deepwater workrequires expensive TMS and deck gear. Fora large percentage of subsea tasks, HRI’svehicles enable those costs to be eliminatedor reduced by 80%, which will improve theeconomics for existing subsea businesses,while enabling new subsea applications andincreasing the potential scale of ocean explo-ration by the world’s research community.”

HRI is currently developing three differentROV models for launch in 2011. The com-pany’s first vehicle, the U-11000, is sched-uled for release in Q1 2011 and will be opti-mized for long-range survey, observation,and light intervention, making it ideal forremote inspection, repair and maintenance

The U-11000 will have arange of as long as 20km from its launchpoint, allowing it to be deployed for certaintasks from shore or from an ocean platforminstead of from a ship, further reducing costof operations as compared to current ROV

systems. HRI’s next two ROVs will belaunched in the second half of 2011, and willinclude the T-6500, designed for a broadrange of tasks below the launch point, andthe F-11000, a hybrid AUV/ROV model,with up to 6 knots forward thrust and a largepayload for sensory and survey equipment.

All American Marine (AAM) will build forC & C Technologies (C & C) a new catama-ran survey vessel. C & C Technologies,which is highly regarded as a pioneer in theuse of AUVs in surveying offshore plots,signed a contract with AAM to build a new134 x 37-ft. aluminum catamaran for surveyoperations in the Gulf of Mexico. The twocompanies have been developing the designconcept for the vessel for nearly two years.Teknicraft Design Ltd. of Auckland, NewZealand will provide the engineering andnaval architecture services for the design,which is expected to be launched and deliv-ered during the second half of 2011.

C & C worked with AAM and Teknicraftto make the custom designed vessel versatileand accommodating to perform AUV opera-tions, water sampling, side scan sonar andmultibeam operations while underway. Thevessel will feature a sophisticated survey labwhich functions as the control center fordata collection during each mission.Transducer wells and deployable sonar strutswere thoughtfully integrated into the hull toensure quality data results. Topside, theworking decks feature an impressive configu-

ration of winches, a-frames, and cranes. Thevast aft deck also provides suitable space forAUV launch and recovery operations as wellas conventional geophysical surveys.

Once complete, the vessel will be kept on abusy schedule, making approximately 20trips annually, each lasting a duration of 14days. The hull tonnage will be certified lessthan 100 gross tons and will include accom-modations for 26 research staff and crew.Caterpillar has been selected to supply theprime movers, inclusive of twin C32 ACERTengines and twin C18 ACERT engines. Thepropulsion configuration will provide acruise speed of 20 knots with a total of 2153bhp in each sponson.The pairing of two different engines allows

for high speed transit to the survey site usingall four engines and a slower survey speedwhen using only the smaller engines.

The C18s are coupled to ZF Marine gearswith trolling valves to provide an economicalspeed range from 3 to 11 knots. Auxiliarypower for onboard electrical needs will besupplied by twin Caterpillar C4.4 gensetsrated 99ekW.

The Roving Bat, a hybrid free-flying ROVand crawler designed and made by CSIP, wasthe star of a documentary recently aired inGermany. ZDF Umwelt magazine, aGerman television program focusing onenvironmental topics, chose to feature theRoving Bat in a documentary about how off-shore activity requires high-tech equipmentto function effectively.

The Roving Bat, equipped with a hydro-carbon leak detection system, was used in thedocumentary and underwater cameras gaveviewers a clear view of the ROV in action.

“When ZDF Umwelt magazineapproached us to use the Roving Bat in thedocumentary, we were only too pleased todemonstrate the ROV’s impressive capabili-ties,” said Simon Gilligan, ManagingDirector of CSIP. “The Roving Bat was orig-inally designed to survey the hulls of ships,underwater structures and hydraulic damsfor any signs of damage. It can also be usedfor the search and disposal of limpet mines

and other explosive and suspect devicesattached on ships hulls, harbor walls or piers,making it one of the most popular vehicles inour fleet.

“The Roving Bat has 6 built-in thrusters, 2longitudinal and 4 vertical, making it verypowerful and capable of withstanding heavycurrents for stable and reliable inspection. Itsbody has been designed to minimize drag,reaching its target in free-flying mode andsticks to any vertical or inclined surface. Itcan then move along this surface in crawlingmode for close inspection and can achievecoverage of up to 20m per minute. With athrust of 80 kg when travelling in a verticaldirection and 48 kg in a horizontal directionit allows the vehicles to operate in extremeconditions.

“Because of these capabilities, it was theperfect example to use in the documentaryand since the documentary aired we havereceived several enquiries from researchers inGermany interested in the Roving Bat.”

Neptune Canada Wiring the Subsea Volcanic Region

On Sunday, Sept. 12, a team of scientists and engineersembarked from Esquimalt, BC aboard the research vesselT.G. Thompson on a deep-sea voyage that will completeinstallation of NEPTUNE Canada, the world’s firstregional cabled ocean observatory. Installation of cable andinstruments at the Endeavour Ridge node site 300 km offthe BC coast will give scientists an unblinking look at howthe region—renowned for its volcanic activity—fits intoand influences marine, climate and tectonic systems offCanada’s west coast.

“NEPTUNE Canada is taking power and the Internet tothe dramatic environments of the mid-ocean ridge,” saidmarine scientist Dr. Mairi Best, co-chief of the expedition.“For the first time, anyone will be able to monitor thisharsh but dynamic edge of a tectonic plate in real-time.”

NEPTUNE Canada is managed by Ocean NetworksCanada for a consortium led by the University of Victoria.It pioneers a new generation of ocean observation systemsthat—using power and the Internet—provide continuous,long-term monitoring of ocean processes and events, asthey happen. Endeavour Ridge will be NEPTUNECanada’s most challenging installation yet. During themonth at sea, the team was to lay three sets of 6 km longpower and fiber optic cables between the node (installed inSeptember 2009) and the scientific study sites. To do thisacross a subsea mountain range 2.3 km below the oceansurface, they need to avoid deep fissures, sharp glass-likerocks and hot vents spewing plumes of corrosive mineralsand gases at temperatures exceeding 300°C. To start, 18instruments will be installed at the site, including seis-mometers to measure tectonic processes, cameras, andmoored instrument buoys to document the ocean currentsand chemical fluxes. Scientists will also observe the uniquedeep-sea “black smoker” ecosystems that flourish in themain hydrothermal vent field. On the way to Endeavour,two major science platforms will be installed at the BarkleyCanyon node site on the continental slope. A two-ton ver-tical profiler system—the first of its kind in the world—will measure nutrients and warmth from the seafloor 400m up to the surface. Wally II, the second generation of theworld’s first Internet-operated deep-sea crawler, will meas-ure processes of seafloor methane hydrates.

Under-Ice Missionfor Bluefin-21 AUV Last month, a Bluefin-21 AutonomousUnderwater Vehicle(AUV) owned by theAlfred WegenerInstitute for Polar andMarine Research (AWI)was sent out on anunder-ice mission andretrieved valuable datathat could shed lighton climate change.The AUV was deployedby AWI and Bluefincrew members fromthe R/V Polarsternabout 79° north.Equipped with an AWI-developed water sam-pler payload, the vehi-cle traveled underheavily packed ice col-lecting 22 samples indiscrete time intervalsfor later analysis. TheBluefin-21 AUV is a3000-m-rated systemcapable of travelingover 70 km at aspeed of approximate-ly 3.5 knots. A missionis configured onBluefin’s MissionPlanner software andloaded onto the vehi-cle computer via anRF link. Once launchedinto the water, the AUVcarries out the missioncompletelyautonomously. Vehiclestatus is transmittedback to the operatorcomputer via acousticcommunications. Uponrecovery, data isdownloaded and thewater samplesremoved for analysis.The AWI cruise beganin Longyearbyen,Spitsbergen on theJune 30. It ended inReykjavik, Iceland onJuly 29.

The ABS Brazil Offshore TechnologyCenter, in partnership with the FederalUniversity of Rio de Janeiro(COPPE/UFRJ), has begun work on its firstresearch project – a multiyear study on theapplication of torpedo piles as an alternativemooring anchor system. The concept hasbeen developed by Petrobras for continueduse offshore Brazil. The study will examinestate-of-the art techniques available to simu-late soil conditions and determine a set ofrequirements and criteria that address theholding capacity and structural strength oftorpedo piles in operation. The study isexpected to result in the development of arational approach for the class review andapproval of the proposed mooring system.The study was launched in early August andis expected to be completed by February2012. According to Christiane Machado,ABS Senior Engineer, Technology, uponcompletion of the study a report with rec-ommendations to the industry will be issuedtogether with guidelines for the design anduse of torpedo piles. The torpedo pile hasbeen recognized as a cost-effective alternativeto traditional anchor-based mooring sys-tems. It has been considered for use in moor-ing floating production systems and mobileoffshore drilling units (MODUs). The pile isinstalled in a free fall operation from a sup-port vessel.

surrounding the design of offshore founda-tion systems, in particular those using torpe-do piles, are the uncertainties related to thedetermination of holding capacity values.The determination of relevant parameters ofsoil characteristics and the final installedposition angles, together with the safety fac-tors to be considered in the design, will beaddressed in this study, explains Machado.“We want to provide a set of parametricequations to better estimate anchor weight,installation limits for penetration distanceand angles and check the adequacy of theinstalled pile holding capacity.” Since theestablishment of the ABS Brazil OffshoreTechnology Center was first announced inMay of this year, it has been fielding propos-als and considering research projects intend-ed to support the development of new tech-nologies for offshore facilities, particularlythose in Brazilian waters.

Recently, the Center applied for Braziliangovernmental funding through FINEP(Research and Projects Financing) to supportthe development of new technologies forpre-salt related engineering. The workwould be carried out in partnership withCOPPE/UFRJ and Rio’s tank testing facility,Lab Oceano, and be focused on the develop-ment of Rules and guidelines for the globalperformance of closely moored offshoreunits.

ESB International (ESBI) enteredan agreement with tidal energy com-pany Marine Current Turbines(MCT) to develop an initial phase ofa 100MW tidal energy project off theAntrim coast in Northern Ireland.ESBI and MCT will work together tosubmit a proposal to the forthcomingMarine Leasing Round in NorthernIreland to secure an Agreement forLease from The Crown Estate tocommence formal consenting of theproject. If successful, and subject tothe achievement of consent, the ini-tial phase of the project, which willuse the MCT SeaGen device, couldbe in operation by 2018. TheESBI/MCT project will assistNorthern Ireland in achieving itsmarine renewable energy targets asoutlined in the Northern IrelandDepartment of Enterprise, Trade &Investment’s Strategic Action Planwhich calls for 300MW of tidal ener-gy by 2020. SeaGen is reportedly the

largest and most powerful tidalstream turbine in the world and theonly one that is regularly generatingelectrcitiy for customers, having beenaccredited by OFGEM, the UKindustry regulator, as an “official”power station. The 1.2MW turbinehas been operating in NorthernIreland’s Strangford Lough sinceApril 2008 and recently achievedanother operational milestone bydelivering its 2 millionth kWh ofpower to the grid.

Thanks to Strangford being anexceptionally energetic location,SeaGen regularly produces as muchelectricity as an average off-shorewind turbine of double the ratedpower.

This power is already being sold byESB’s retail electricity supply busi-ness, ESB Independent Energy, tocustomers in Northern Ireland. ESBChief Executive, Padraig McManus,said ESB's strategy to 2020 involves

focusing on sustainable and renew-able energies. "We look forward toworking with MCT on this excitingnew project. Our aim is to use ourexperience and technical strength tosupport the development of a viableocean energy industry in Ireland andthis project is an important step inrealising that goal", he said.

Martin Wright, Managing Directorof Marine Current Turbines said"This agreement underlines the suc-cess to date of the SeaGen project inStrangford Lough but importantlythe real and growing commercialinterest in tidal energy.

Our agreement with ESBI, whichhas been a valued shareholder inMCT for 2½ years, confirms MCT'stidal technology at being in the fore-front in the race to harness the powerof tides.

We are pleased that ESBI has cho-sen MCT to develop the initial phaseof this project."

Offshore Ship Designer's first proj-ect in the marine renewable energyfield will shortly be commencing onsite trials in the UK's Humber estu-ary. By applying its experience anddesign knowledge, OSD has helpedUK company Neptune RenewableEnergy Ltd (NREL) to develop aninnovative device to capture thepotential of tidal stream energy. TheProteus NP1000 full scale demon-strator will harness tidal currents toproduce at least 1000 MWh/year ofelectrical energy.

"There are plenty of innovativeideas on how to turn marine energyinto usable power on the energy net-work,” said Michiel Wijsmuller, man-aging director of OSD. “However, ittakes solid marine engineering skillsand design experience to turn thesenovel ideas into practical workablesolutions, and that is where OSDcomes in. The basic and detaileddesign of the NREL patented conceptwas developed in OSD-IMT's officesin the UK. The target capital cost permegawatt of power generating capa-bility of the device is very competitivewith wind power generation and,unlike wind, tidal stream power iscontinuous and not intermittent."

The original concept for the tidalcurrent generator was developed atthe University of Hull, where initialCFD, mathematical and physicalmodeling was carried out. In 2008Neptune Renewable Energy was ableto secure private investment to enablefunding of the full scale demonstra-tor, and OSD turned the concept intoreality with a full structural design toLloyds Register approval, advice onequipment sourcing and buildingsupervision.

The NP1000 is a catamaran typestructure 20m in length, 14m wideweighing more than 150 tons. It wasbuilt in Sunderland under the super-vision of OSD-IMT and was trans-ported by barge to Hull where per-formance trials to validate the con-cept will be undertaken.

Installed in the steel hull is a 6 x 6mvertical axis crossflow turbine mount-ed within a patented, asymmetricalVenturi diffuser duct. The verticalturbine shaft connects through a rightangle gearbox to two permanent mag-net DC generators mounted in analuminum deck house. The power iscabled ashore and connected to thegrid via industrial regenerative drives

and control systems. The device isdesigned so that almost all mainte-nance and component replacementcan be carried out on site. TheNP1000 will be moored in the freestream to minimize environmentalimpact and operates equally efficient-ly for both flood and ebb currents.The rotor is maintained at optimalpower output by means of computercontrolled shutters within the duct.

Future plans following full scaleonsite tests are to install a further tenunits in the Humber. There are atleast ten more estuary sites around theUK, and hundreds worldwide, whichpotentially could support this newtechnology.

Legal Beat

After the Deepwater Horizon ...

What Now Offshore?By Jonathan K. Waldron, Blank Rome LLP

Who could have predicted such an incident? As dis-cussed in more detail below, the aftermath of this incidentis raising more questions than answers now that the focuscan turn from the response efforts to claims efforts andfuture improvements. According to reports as of this writ-ing, BP has spent more than $8 billion in the response andthe Administration sent a sixth bill for another $128 mil-lion to BP and the other Responsible Parties in earlySeptember 2010. BP paid the previous five bills totalingalmost $390 million. In addition, more than 42,000claims have been filed against the new Gulf Coast ClaimsFacility since it opened in August 2010 and approximate-ly $80 million has been paid since the BP claims weretransferred to the Facility. BP has made approximately127,000 payments totaling about $400 million prior tothe transfer of the claims to the new Facility.Investigations are ongoing, it is unclear what legislationwill ultimately be enacted, and the moratorium continues.

Law Suits and ClaimsThe Multidistrict Litigation Panel (MDL) has ruled that

the suits pending against BP and others relating to theDeepwater Horizon oil spill will be consolidated for allpre-trial purposes before Judge Barbier of the U.S. DistrictCourt for the Eastern District of Louisiana. Judge Barbierhas set the initial pre-trial conference for the MDL forSeptember 16, 2010. The purpose of this conference is,in part, to establish case management orders for the pro-ceeding. It is unclear how long these cases will take toresolve.

On August 23, 2010, the Gulf Coast Claims Facility(GCCF), administered by attorney, Kenneth R. Feinberg,trustee for the $20 billion fund established by BPExploration & Production Inc. (BP) to settle claims aris-ing from the Deepwater Horizon casualty, opened forbusiness for the receipt of claims. Claimants can file forEmergency Advance Payments (EAPs) between August 23and November 23, 2010 in accordance with the GCCFProtocol for Emergency Advance Payments and for FinalPayments until August 23, 2013.

Although claims for Final Payment can be submitted tothe GCCF now, the EAP Protocol published on August

23, 2010 addresses only claims for EAPs and not FinalPayments. A subsequent protocol will be published toaddress Final Payments at a later date. Any party suffer-ing damages or seeking reimbursement for removal costsas a result of the Deepwater Horizon casualty should con-sider submitting a claim for an EAP as a bridge until theclaimant’s full damages or removal costs can be fullyassessed. Obtaining an EAP from the GCCF will notjeopardize a claimant’s right to purse full compensationwith the NPFC or against a responsible party through lit-igation if not satisfied with action taken by the GCCF.

If a claimant, however, is either not satisfied with theEAP payment offered by the GCCF or desires to pursue aFinal Payment now, it does not appear that GCCF will beready to act on a claim for Final Payment until the FinalProtocol is issued. Once a claimant desires to move for-ward with a determination of a Final Payment from theGCCF, the claimant should be prepared to sign a Releaseand Waiver of Rights for any future claims as a result ofthis oil spill as a condition to receiving payment, or beprepared to litigate the matter or pursue the claim againstthe NPFC. Either of these options can take years toresolve. Claimants should consider conferring with legalcounsel to ensure they understand all options available tothem.

InvestigationsThe joint Coast Guard and Bureau of Ocean Energy

and Management (BOEM) investigation continues todevelop conclusions and recommendations as they relateto the Deepwater Horizon explosion and loss of life onApril 20, 2010. The facts collected at this hearing, alongwith the lead investigators' conclusions and recommenda-tions will be forwarded to Coast Guard Headquarters andBOEM for approval. The Blow-Out Preventer was justraised and it is only now that the government has anopportunity to review this evidence and the investigationhas recently been extended to at least November 2010. Itis unlikely that anything will be finalized until 2011.

Meanwhile, the Department of Justice (DOJ) continuesits investigation and has not publicly released any infor-mation on its status. However, the stakes are high, as thespecter of a possible finding of gross negligence looms in

this case and DOJ could purse substantial criminal andcivil fines. For example, on a per barrel basis, a civil penal-ty could be pursed in the vicinity of $5.4 billion. If thereis gross negligence the fine could be up to $21 billion.

In addition, the National Commission on the BPDeepwater Horizon Oil Spill and Offshore Drilling, con-sisting of a bipartisan presidential commission, establishedby Executive Order by Barack Obama on May 21, 2010is continuing its work to provide recommendations onhow the United States can prevent and mitigate theimpact of any future spills that result from offshoredrilling.

Spill LegislationIn response to the Deepwater Horizon incident, numer-

ous hearings have been held with a focus on the econom-ic and environmental effects of the spill, as well as theimpact of the oil rig explosion on offshore oil and gasdevelopment policy. When Congress broke for the sum-mer recess, the House had passed H.R. 3534, theConsolidated Land, Energy, and Aquatic Resources Act of2009 (the CLEAR Act). This bill incorporated key provi-sions from a bill introduced by Congressman Oberstarthat would, among other things, repeal limits of liability,increase the minimum level of financial responsibility foran offshore facility to $1.5 billion, authorize recovery fornon-pecuniary damages and human health injuries,require all vessels engaged in OCS activities to operateunder the U.S.-flag and be 75% U.S.-owned (and aMobile Offshore Drilling Unit (MODU) would also haveto be built in the United States), and substantially revisethe oil spill response planning and safety regimes for ves-sels, facilities, and MODUs.

The Senate, on the other hand, failed to pass a bill, butconsolidated proposed oil spill legislation in S. 3663, theClean Energy Jobs and Oil Spill Accountability Plan,which was introduced by Senator Reid on July 28, 2010.It became clear, before the Senate on August 6 went onsummer recess, that there was opposition, both on theDemocrat as well as the Republican side of the aisle.Senator Begich (D-AL) and Senator Landrieu (D-LA),both critics of the unlimited liability language in S. 3663,introduced separate measures shortly after S. 3663 wasintroduced intended to hold oil companies accountable,without placing a burden on taxpayers and shutting small-er companies out from operating offshore. In addition,the Republicans have their own legislation in play, S.3643, the Oil Spill Response Improvement Act of 2010,

introduced by Senator McConnell (R-KY) on July 22,2010. Given the pressures involved with re-elections andother priorities, it is unclear whether the Senate can passspill legislation this fall and then work with the House tofinalize and enact spill legislation before the end of theyear. If not this year, then most certainly it will be a majorissue in 2011.

MoratoriumOne of the key impacts of the spill incident is the six-

month moratorium the Obama administration imposedon new deepwater drilling permits in May 2010 followingthe April 20 blowout. Although a federal judge in NewOrleans blocked the ban after a number of energy compa-nies filed suit challenging it, on July 12, 2010 the InteriorDepartment replaced it with a revised one with addition-al justifications. The revised ban is still being targeted byindustry to overturn it. Given the substantial economicimplications, the moratorium is not only having directlyon the offshore oil and gas operations, but also indirectlyon the industries supporting these offshore activities.

The implications of the Deepwater Horizon are stagger-ing. The oil impacts were substantial and the resultingclaims, including for economic damages, huge. Manycompanies are simply considering whether it is worth con-ducting such operations in U.S. waters given all the uncer-tainties. Claims and lawsuits will continue for an extend-ed period of time. We await the results of the investiga-tions and Congressional action in determining actionsthat will be taken against BP and possibly otherResponsible Parties and the potential for a completelyrevised offshore liability, prevention, and response regime.In the interim, stakeholders should continue to letCongress and the American public understand the impor-tance of their interests, and the potential implications, toassist in resolving these outstanding issues.

Underwater Visualization to

Enhance Underwater Inspections

www.seadiscovery.com Marine Technology Reporter 27

28 MTR October 2010

By Simon Marr, Visualsoft Ltd.Digital Video to support subsea pipeline and structural

inspections has been around for more than a decade nowand has become well established offshore. However, thequality of results and the time to conduct surveys is high-ly dependent on water turbidity, lighting and the ability ofROV pilots to locate and navigate to inspection targetsefficiently. Good visualization and graphic representationof inspection targets within the field is therefore essentialfor workscope planning, conducting surveys safely andefficiently, and for performing faster visual inspectionsbased on easy access to and better understanding of thesurvey data collected. In this article VisualSoft Ltd.,describe methods of enhancing the optical imagery andother methods of imaging targets and then explain thebenefits of Augmented Reality Viewers for planning andtracking surveys and how they can be used with existingsurvey toolkits.

Advent of High Definition VideoDigital High Definition (HD) video is any video image

with a vertical resolution of 720 or 1080 rows and a hor-izontal to vertical aspect ratio of 16:9. This results in

image sizes of 1280 x 720 and 1920 x 1080 respectivelywith one or two million pixels per frame, roughly fivetimes that of Standard Definition (SD). Another impor-tant difference is analogue SD video is recorded to thePAL specification which only records at 25 frames per sec-ond – 720 and 1080i can record at 30 fps and 1080p canrecord at up to 60 fps.

For subsea inspection surveys, HD shows significantlymore detail and the video imagery appears crisper andmore vibrant. This makes it highly suitable for close visu-al inspections of pipelines, ship hulls and subsea structureswhere the early detection of cracks, corrosion and otheranomalies is mission critical. HD is also rapidly becomingthe standard for marine scientists involved in habitat map-ping and site surveys. The higher frame rates possibleshould improve resolution when recording video from amoving vehicle.

HD adoption has been hindered by technical hurdlessuch as getting the raw signal from the camera into theROV control pod and by the higher costs of multiplexingand transporting the signal up the umbilical to the sur-face. Another challenge of upgrading to HD has been theincreased storage requirement. HD video recording

records at 12-20 Mbps which generates up to 216 GB percamera per day which corresponds to 3-5 times the cur-rent storage volume required for SD/PAL digital videorecording. For inspections that require synchronisation ofvideo from multiple cameras, a more flexible solution istherefore desired. VisualSoft tackled this issue by develop-ing a recording solution that allows one channel (the maincamera) to record and playback in HD and other channelsto record and playback in SD. Results from an HD surveyof Bergen harbour showed considerably more detail onseabed objects and the video footage was noticeably clear-er.

Dealing with Sub-Optimal VisibilityMost inspection surveys are conducted in less than ideal

conditions and HD can sometimes exacerbate the situa-tion by making disturbances more visible. Visibility maybe poor because of sediments or algae in the water or dueto a lack of light. Careful attention therefore needs to bepaid to matching the lighting to the camera and to theenvironmental conditions to avoid saturation. Wherethere is high turbidity, or silt kicked up (for example bythe thrusters of an ROV) the imagery can be badly

obscured by suspended particles causing a ‘snow’ effectthat can be hard to decipher.

During close visual inspection using remote vision andreal-time video the human observer needs to be able todetect and classify anomalies such as cracks and coatingfailures as structural members are scrutinized. There aresome solutions that can be plugged into existing videorecording systems such as LYYN. Operating in real-timethis unit helps to reduces visual disturbances from parti-cles or algae, and removes predominant tinting fromorganic matter and increases contrast in surface coloursfor better inspection results.

Imaging sonars are another technology used to deal withlow or zero visibility: these are sometimes referred to asacoustic cameras. These systems enhance real-time under-water navigation, obstacle avoidance, and object detec-tion, tracking and classification with high levels of accura-cy and offer 2D or 3D visualization to extremely high res-olutions. They can offer near video quality results in tur-bid and very deep waters.

Model-Based Augmented Reality ViewersVision-based systems that rely on optical improvements

and digital enhancement are only capable of improvingimagery within a few meters. Imaging sonars can detectand classify objects based on shape at a greater range butcannot show component detail clearly at greater distancesor the positions of multiple structures in what may be acomplex subsea field layout with infrastructure spread outover several kilometers. Augmented Reality (AR) Viewersoffer the ability to rapidly fly through and view field assetswith perfect visibility either from the perspective of anonboard ROV camera or from any stand-off distance.This improved situational awareness and ability toinstantly jump to and view individual asset componentsenables faster field familiarization and saves considerabletime during survey planning and when reviewing results.Additionally, being able to zoom in and rotate aroundstructures to see more component detail and consider dif-ferent methods of access enables Inspection Engineers toplan survey inspections using ROVs well in advance.

The field view is built using accurate models of struc-tural members and components. Owners often have theirown nodal identification hierarchy which can be used foreasier recognition and tracking within the AR viewer dur-ing inspection. For greater efficiency and return on invest-ment, these models can be re-used at each stage of theinspection process from definition of a task basedworkscope generation, through the offshore inspectionprocess and on to the subsequent analysis and review inclient offices.

The virtual field is laid out based on survey positions ofassets. Significant operational downtime is saved by plan-ning a course that stays clear of obstructions/risk areas andby working out how to approach inspection targets in asafe and efficient way. This technology is moving fast andit is now possible to track live positions within this virtu-al world. By attaching position, pitch, roll and headingsensor feeds to one or more ROVs/vessel models it is pos-sible to update the 3D model in real-time showing trackdata, camera views and multi-beam coverage of theseabed. This is leading to a real-time network distributedview of all field operations within the 3D Field Model. Awider audience benefits from being able to view live oper-ations within the field: pilots, crane operators, operationssupervisors/superintendents, owner/operator representa-tives and increasingly onshore teams who may access thesystem via a SatCom link. Direct, real-time ROV positionfeedback through an AR Viewer can also be used along-side existing vision-based systems to aid pilot navigation.

Used as part of an Integrity Management (IM) solution,AR Viewers offer front-end access to different client struc-

tural datasets in a single 3D simulation of the field.Datasets are mapped to specific structural component IDsso that users can see and extract catalogues of data fromcurrent or previous inspection campaigns for comparison,interpretation and risk management.

Inspection Workscope VisualisationInspection Engineers need to take a lot of factors into

consideration when deciding how to implement aninspection strategy. Different types of asset have differentrisk factors so inspections need to be tailored to the asset.Risk-based techniques are used to decide when to inspectand what types of failure to target. Inspection Engineersuse their experience together with knowledge of the age ofthe asset, its original expected design life, its inspectionand repair history, and its operational environmental todefine a work scope of inspection targets. The ability toeasily visualize, review, select and sequence different com-ponents for inspection based on ready access to this kindof target information makes inspections quicker to plan,track, audit and report on.

However, Inspection Engineers get what they inspectrather than what they necessarily expect. So what happenswhen unusually aggressive deterioration is observed or theInspection Engineer finds anomalies in areas where it wasnot expected? After anomalies are logged and classifiedmore evidence needs to be collected to see how wide-spread the effects are, and to find out if other componentsof the same type are affected to a similar extent. Therefore,Inspection Engineers need online tools to record what isfound, keep track of what has and has not been inspectedand be able to modify the scope of work as required toundertake more detailed inspections or to survey a largersample of targets.

To get a comprehensive picture, Inspection Engineersneed to tie all inspection data together. This is a complexproblem that requires synchronisation between the onlinedata acquisition system, offline review system and compo-nent model datasets. It involves linking recorded video,survey positioning, sensor measurements and conditionobservations with members and components and thenproviding access to histories of previous inspections.Referential documents such as standards, classificationrules, company rules and procedures for inspection alsoneed to be readily accessible. Having all this data in oneplace and accessible using a single user interface makes itmuch easier and faster to conduct condition analysis andgenerate inspection reports.

Improving workscope visualization and task tracking

was VisualSoft’s motivation for Visual3D-Inspector, a newadd-on module to the VisualWorks Inspection Suite.Using Visual3D-Inspector, Inspection Engineers prepareand preview inspection workscopes and track completionsusing a set of inspection and visualization tools integratedwith online video and sensor data acquisition and withoffline video review and event editing. These tools alsointegrate with the leading software packages in the indus-try such as COABIS, EIVA, and Netlink to allow clientsto see their data the way they want to see it. The ability toeasily view information and understand complex spatialdata from numerous different sources is extremely impor-tant in our data rich world. VisualSoft allow users tochoose between viewing data through the client’s owngeo-spatial database structure/GIS or using theVisualReview program which is distributed free of chargeand can be bundled together with the data on a CD/DVDfor automatic playback.

Practical DeploymentAs well as being designed for inspection workscope visu-

alisation and tracking, Visual3D-Inspector can also beused for post-inspection visualisation of legacy data. Forexample, VisualSoft recently deployed the Visual3D-

Inspector Viewer to a client in Egypt who wished to mapinspection data they had collected of their platform usingVisualWorks. This involved importing the platformmodel and automatically mapping its component list ofconductors, elevations, faces, legs, risers, guards, etc to aclient-specific project tree containing the survey data. Theselection of components in the 3D Model Viewer enabledthe client to jump directly to the component list to seewhat survey data has been collected and then step throughall recorded event anomalies reviewing what had beenobserved and what features had been recorded. Thisallowed the client to visualise and interpret all survey dataof the platform from their desktop PC, conduct rapidcondition reviews and extract relevant video sequences,clips and stills and event details for submission of findingsto their client. For future surveys they will be able to useVisual3D-Inspector from the start of the job and fortracking component inspection records for time-basedcomponent analysis.

VisualSoft is presently discussing other deployments oftheir integrated 3D Model Viewer with clients who wishto link together pipeline/structural and FPSO/Ship Hullinspection surveys in a single application and to integratewith existing GIS databases.

The Mexican Institute for Water Technology (IMTA)had big questions to answer as it studied plans for theexpansion of the Port of Manzanillo, an important con-tainer shipping center on Mexico’s Pacific coast. The portauthority received permission to upgrade the harbor onthe condition that it restore an adjacent lagoon, cut offfrom the rest of the harbor by a road embankment decadesago. Reconnecting the lagoon to the sea will return circu-lation to the system and improve water quality. However,the lagoon has evolved into a freshwater system highlyimpacted by wastewater from the surrounding communi-ty, which has become home to mangrove stands and thebird populations that led it to be dubbed Laguna de lasGarzas – Lagoon of the Herons. Biologists raised concernsthat simply opening the lagoon to the harbor would alterthe lagoon’s salinity too quickly, stressing the mangrovesand threatening the ecosystem that has developed there.

“We needed some environmental studies related to cir-culation and how to maintain good water quality,” saysDr. Rubén Morales of IMTA’s Grupo de HidráulicaAmbiental (Environmental Hydraulics Group) inJiutepec, Morelos, Mexico.

“We wanted to understand the dynamics of the harborinduced by tidal forcing and gain insight into the verticalstructure of the water column.

With that information,we could predict what was goingto happen when they opened the canal between thelagoon and the harbor.

We needed to study the residence time of fresh water inthe lagoon and the canal.”

Working in a small boat in a harbor that rarely exceeds50 feet (15 meters) in depth, Morales, Ariosto Aguilar andArmando Laurel harnessed the power of a new, palm-sizedinstrument – the CastAway-CTD from YSI – to get aclearer understanding of the dynamics of water column inManzanillo. Weighing just one pound (0.45 kg) andreeled in and out on a fishing pole, the CastAway-CTDinstantly delivers the same information that typicallyrequired a heavy, bulky instrument and extensive dataprocessing.

New ToolThe CastAway-CTD uses its patent-pending design to

collect high-resolution data on its free-falling downcast,and to continue logging conductivity, temperature anddepth readings as it is reeled back up through the watercolumn. Every cast is georeferenced by the instrument’sbuilt-in GPS. The CastAway-CTD has no moving parts –instead, an innovative flow-through design keeps water incontinuous contact with the instrument’s sensors, whichcapture data at a sampling rate of 5 Hz, or five samples persecond. The CastAway-CTD temperature sensor respondsin less than 200 milliseconds, the pressure sensor is accu-rate to within 0.25 percent of FS, and its unique conduc-tivity cell is contained to shield its six specially arrayed andsequenced nickel electrodes from the possibility of errorsfrom nearby conductive materials.

The result is data as accurate and as high in resolution asa previous generation of heavy, complex conventionalinstruments can gather – without the headaches andstrained muscles. The CastAway-CTD also eliminates thehassles of field maintenance. A rinse with fresh water andan occasional scrubbing of the electrodes with dish soapare all that is required to keep the instrument ready fordeployment in the field.

Calibration is handled by YSI during annual factorymaintenance. Power is supplied by a pair of AA batteries,accessed by a simple twist of the rugged plastic housing. Infact, the only tool required to operate the CastAway-CTDis a plastic stylus to activate the unit’s features. Almostimmediately after each cast, the unit’s built-in color LCDscreen displays data points and graphs depicting conduc-tivity and temperature versus depth – the measuredparameters – as well as derived values for speed of soundand salinity. The instant feedback on the water column,allows users to adjust their sampling programs on the fly,doing additional casts or targeting specific areas or depthsfor further study.

“You can understand what’s happening and you can say,‘I need more data’ and cast again,” Morales notes. “It’sreally incredible because we can even plan at which depthwe should sample.” With the lightweight CastAway-CTD, doing another cast is simple and painless, especial-ly compared to hauling a larger unit. “We probably did 50percent more casts because it’s so simple, you want to tryit wherever you go,” he says.

Complex Dynamics in a Small Harbor

Intuitive SoftwareAfter viewing data from each cast on the LCD screen of

the CastAway-CTD, Morales and his colleagues used theunit’s Bluetooth connection to upload data onto a com-puter running YSI’s Windows-compatible CastAway-CTD software.

The convenience of a dedicated, wireless connection –no cords snaking around the boat, no pins and connectorsto step on, no worries about compatibility or handshaking– was matched by the convenience of working with theintuitive software. CastAway-CTD software plots everycast – georeferenced with GPS coordinates, time stampand unit number – on an interactive map. With drag-and-drop functionality, users can group or compare data, cre-ating tables and graphs with the click of a mouse.

“It’s definitely very easy and very practical to see theplotting of the data,” says Morales. He used CastAway-CTD software to view and graph the data from his field-work and publish it in his preliminary report. For furtheranalysis, it is quick and convenient to export data from theCastAway-CTD to industry standard software packagessuch as Excel, Hypack and Matlab.

Morales and his team saw a significant lateral tempera-ture gradient – two degrees C at 12 to 14 meters in depth– at the entrance to the harbor. Guided by data from theCastAway-CTD, they gathered current data with aSonTek acoustic Doppler profiler (ADP) to determinethat water flows through Manzanillo harbor in differentdirections on either side of the thermocline (a two-layerflow).

“At the main entrance to the lagoon, there is a verystrong lateral gradient, which is really important in thedynamics of the harbor,” Morales reports. “Travel in thesurface layer is toward the sea. At the same time, water inthe lower layer is moving toward the port.

Normally, it is thought that in small, semi-enclosed har-bors the circulation is barotropic, but in the Manzanilloharbor, there is two-layer flow, which has been corrobo-rated with the CastAway-CTD and a towed SonTek ADP.That’s important to understanding residence time and thedistribution of pollutants inside the port.”

Identifying the temperature gradient in the water col-umn illustrated to Morales and his colleagues the need toassess the port with more powerful models than they hadbeen using before. “Normally we think we can model cir-culation with 2-D models, but what we found is that har-bor dynamics in Manzanillo are not as simple as every-body thinks,” he says.

Morales’ future work will continue taking him to coastal

lagoons and inland lakes to study vertical structure andmotion in the water column. The instrument’s high-reso-lution data and instant feedback are sure to yield moreinsights into the dynamics of Mexico’s extensive coastalwaters as well as lakes that supply drinking water to areacommunities.

“It’s really important for us to understand the structureof coastal lagoons,” he notes. “We can also take theCastAway to an inland lake to measure stratification andsee how the water is mixing. If we have stratification dur-ing the summer, we can have anoxic areas. In some cases,we will want to have mixing systems to improve waterquality.”

Existing equipment has reliably provided CTD data foryears. But those huge, heavy, complicated systems can bea real challenge to manage in the small boats that Moralestends to use in his research. The appeal of the CastAway-CTD – its accuracy, convenience, flexibility and speed –all of which are contained in a carrying case the size of alunch box.

“Normally, in coastal studies, we just need a small boat,”Morales says. “It’s easy to just take the CTD in its box. It’snot cumbersome.” For more information on theCastAway-CTD, visit

Off the coast of the Dunwich inSuffolk lies half a medieval townlong since abandoned to theencroaching sea. Despite manydiver and sonar surveys, the extentand detail of the well-known site arestill unknown as poor visibility frus-trates its study. In June 2010,acoustic imaging technology wasintroduced to archaeological surveyof the site, revealing news detail.

The site of the sunken town ofDunwich has been the subject ofdebate for several centuries and thequestion of how much of theancient capital of East Angliaremains just off the coast has beenthe subject of countless diving andarchaeology projects. Since the1300’s, historic buildings have beenlost to the relentless encroachmentof the North Sea but attempts togain any detailed view of what liesbeneath the water, the silt and thesand off the coast have been frus-trated by the poor visibility near theseabed. Tidal and wave currentskeep fine sediments from the seabedin suspension, causing the poor vis-ibility within lower meters of theseawater that limits diving andhampers archaeological survey.

In June 2010, a team workingwith the BBC and MacArtneyUnderwater Technology employedtechnology to examine the site.Marine Archaeology Professor,David Sear, based at the Universityof Southampton’s School ofGeography teamed with diversincluding Andy Rose from the div-ing instructor company, LearnScuba, and enlisted the help ofsonar imaging expert, MikeSawkins from the MacArtneyUnderwater Technology Group.

They deployed a special sonar cam-era, the diver held (or DH) DID-SON. Each diver clipped onto ashot line which had been previouslypositioned over the ruins using GPSnavigation and side scan sonar data.The divers could then undertakecircular sweeps of the sea bedaround the shot line, graduallyincreasing their radius. A set of datawas taken hanging over the ruins ata distance of between 8-15m, andthe second set for close up visualisa-tion at 1-5m within the ruins. Thecombination of high frequencies,acoustic lenses and very narrowbeams increased the image detailand gave archaeologists greaterdetail of the site than ever beforeavailable: The DIDSON diver heldsystem enabled us to see for the firsttime the worked and rubble mason-ry on the seabed from the ruins ofSt Katherines Chapel and StNicholas Church lost to the sea inc.1550 and 1480 respectively. Thisability starts to open up the optionsfor marine archaeology in nearshore shallow turbid waters aroundcoasts,” explained Professor Searfrom the University ofSouthampton’s School ofGeography.

A 3D sonar technology of theCoda Echoscope is set for newdecommissioning projects in theNorth Sea and the Gulf of Mexico.The benefits of the Echoscope’s 3Dcapabilities, which bring real-timevisualization to the underwaterworking environment, were sub-stantiated in a successful role in arecent ‘plug and abandonment’task in the Gulf of Mexico, under-lining its suitability for entry intothe decommissioning arena.Echoscope technology generates areal-time 3D image from oneacoustic transmission, or ping, andfrom a single ping over 16,000range and bearing points are gener-ated. The total viewing angle meas-ures 50˚ x 50˚ and within thisacoustic volume, an instantaneous3D image is generated.Commercial achievements withEchoscope technology have beendocumented in a range of diverseapplications including ROV opera-tions where, as an intuitive aid tothe ROV pilot, real-time 3D visu-alization augmented his spatialawareness when navigatingthrough complex structures.Other projects include offshorewind farm installation and under-water breakwater construction; inall cases improvements in opera-tional efficiency are reported.

The Panama Canal Authority completed the first roundof tests in the installation of its new ElectronicNavigational Chart (ENC) system using CARIS softwareat the Simulation Center, Researchand Development Maritime inPanama. This new system will bedesigned to make navigation in thePanama Canal both safer and moreefficient. Currently the Panama Canalcarries around 13,000 oceangoingtransits per year with a total weight of300 million tons; close to capacity forthe canal. In addition to aiding navi-gation, the new system is designed toenhance maritime security, as well as providing more car-tographic information, allowing greater precision whennavigating through the waterway.

The Panama Canal Authority worked in close partner-ship with CARIS to provide the data components of the

cartographic database of the Panama Canal. This includ-ed information relating to the new locks and the depths ofthe various areas of the sea route. CARIS provided the

training and support to fully utilizethe selected CARIS software. ThePanama Canal Authority acquiredBASE Editor for the creation andmanagement of bathymetric surfacesand S-57 Composer for the produc-tion of ENC’s. The project entailedthe creation of two main electroniccharts: one for the Atlantic coast andone for the Pacific coast, as well asother more specific cartographic prod-

ucts within the canal. These ENC’s are initially being usedin a simulator as part of the training program for the canalpilots. In the future the ENC’s will be mandatory for anyvessels approaching or intending to transit the canal.

DNV Confirms Seagen’s Performance

Det Norske Veritas (DNV) issued aStatement of Conformity to certifythat the performance of the 1.2MWSeaGen tidal turbine has been cor-rectly evaluated according to theprinciples contained in the“Edinburgh Protocol” - the protocolfor tidal turbine testing developed bythe University of Edinburgh for theUK Government’s Department ofEnergy & Climate Change, and alsoEMEC’s own testing protocol.

DNV undertook a detailed reviewof the measurement program used byMarine Current Turbines (MCT) fordetermining the performance of thecompany’s SeaGen tidal energy tur-bine which has been operating inNorthern Ireland’s Strangford Loughsince 2008. DNV has verified thatthe measured results have been cor-rectly obtained and interpreted.Some key results that came from thisprogram indicate that SeaGen hasmet its design goals with the peakefficiency for both rotors on bothtides averaging 48% (Cp = 0.48) and

the best result was a peak efficiency of52% and worst peak was 45%. Thecorresponding overall system efficien-cy, including all losses in the genera-tor, gearbox and power electronics,was found to be in the range 40 to45%; that is the proportion of energy

in the flow of water intercepted bySeaGen’s rotors that can get deliveredas electrical energy into the grid.Peter Fraenkel, Technical Director ofMCT, said “Our engineering teamare delighted that SeaGen has beenshown to deliver such good results.”

Perth-based TSmarine Asia Pacificsigned a multi-year service contractwith leading international oilfieldservice company Expro. The con-tract, through TSmarine’s newAberdeen-based subsidiary SALTSubsea Ltd, will deliver worldwidesupport for Expro’s groundbreakingsubsea well intervention system AX-S. The deal has a potential value of$100m. TSmarine Asia Pacific chiefexecutive officer John Edwards saidAX-S would change the way oil andgas companies work on their subseawells in the future, saving time andmoney.

“There are about 4,000 oil and gasproducing subsea wells around theworld and this number is growing,”Edwards said. “Many wells are morethan a decade old and require servic-ing to allow for maximum oil andgas recovery. “Current methodsinvolve positioning a rig above thewell while the work is carried out,which is time-consuming and expen-sive with rigs costing up to a milliondollars a day.”

Expro’s AX-S subsea system is 35 mhigh and weighs 220 tons and isdeployed from a monohull vessel,such as TSmarine’s DP2 DNV-classed intervention vessel HavilaPhoenix. The system can be loweredon to any subsea well down to adepth of 10,000 ft., providing a saferand cheaper alternative to currentpractices. Under the contract, SALTSubsea will supply the HavilaPhoenix, a 110m long vessel built in2009; dual Schilling 4,000m-ratedUHD Workclass ROV systems; spe-cialised tooling packages; survey andpositioning and overall marine man-agement of the vessel.

The Schilling UHD ROV systemswere selected by SALT Subsea fortheir compatibility with the AX-Scontrol systems and sub-assemblies,further enhancing the inbuilt redun-dancy and reliability of the system.

The Havila Phoenix and AX-S willbe mobilized in Europe duringOctober and commence a series ofdemanding offshore trials beforebeing deployed for operational use.

MacArtney’s new AmericanPetroleum Institute (API) approvedconnector helps ensure Hydril’s newblow out preventer system will func-tion if needed. Automatic BOP sys-tems constantly monitor the well andare designed to be fail-safe devices.Not only must they be periodicallyinspected and tested, the AmericanPetroleum Institute sets standardsthat are clear about the types of risksagainst which such equipment mustbe protected. New designs are rigor-ously tested and certified and eachelement must meet stringent require-ments before being API certified.

The size of the preventers and thedepth at which they are deployedmakes them impractical to bring tothe surface often for testing. And asdrilling sites are in increasingly deep-er waters, BOPs have become moreadvanced. They must withstand theincreased pressures at depth and theymust also be reliable enough to per-mit increased intervals between testsor servicing. Systems and equipmenton the BOP can be submerged for upto a year between servicing and musttherefore be resilient to the harshunderwater environment.

When Hydril was designing its newBOP Control System, the companyneeded a complete infrastructurepackage that met the strict standardsfor testing and reliability stipulatedby the American Petroleum Institute.The connector system within thecomplete unit needed be able to with-stand submersion for extended peri-ods and accommodate several failuremodes stipulated in the AmericanPetroleum Institute Pressure Controlsguidelines. These stipulations includ-

ed the requirement for the umbilicalor termination assembly to functioneven when fully flooded with seawa-ter and continue to operate for anextended period without conductorfailure. A comprehensive design,build, test and deploy, program wasimplemented to fulfil the require-ments of outfitting Hydril with threerig packages and just as many sparesand test units. The brief was to fulfilAmerican Petroleum Institute stan-dards 16D for testing when assem-bled and the harder to attain 17E forfunctionality when flooded. Ensuringthat connectors for the infrastructuresystem would function even if thecable was flooded required the com-bination of several design features. Aboot was fitted behind the connectorto ensure that any water entering thecable cannot penetrate to the connec-tor and the connector will continueto work for its intended lifespan evenwith water flooding in the cable rightup to the boot. For 17E standard cer-tification, the cable is as important asthe connector. The cable was selectedfor its ability to withstand wearunderwater. The conductors insidethe cable are also protected to preventwater ingress shorting the connec-tions. Critical to the design wasensuring that the connector could betested for integrity once assembled.MacArtney designed and integrateddouble test ports on the API connec-tor itself to allow pressure testing ofboth sections after mating and beforethe connection is lowered into thewater. Each system needed to be fail-proof on delivery and was tested atvarious stages of production andcompletion. Every element in the

cable was tested individually beforeconstruction to ensure that they wereentirely intact and fully functional.The cable, and then the connectorand cable were pressure tested beforecompletion. The entire cable andconnector unit were ultimately pres-sure tested prior to inclusion in theinfrastructure package. The systemhas evolved over several years into acomprehensive high reliability powerand communications infrastructurepackage for semi-submersible drillingrigs in operation around the world.The complete infrastructure packageincludes fibre optic media converter,multiplexer, MUX cable, slip ring,subsea stress termination, subseaFITA terminations, all subsea harnesscable and POD connections.

The birth of a new rangeThe connectors have achieved a

type certification that controls vari-ous design parameters and governsthe production, testing proceduresand metrics. MacArtney can vary theconnector form factor of these con-nectors provided they fall under thetype certification requirements andnow offers a range of API (AmericanPetroleum Institute) approved con-nectors.

Lightweight Electric Manipulator Arm Since the launch of the

first 5 Function ElectricUnderwater ManipulatorArm, CSIP has developeda lightweight version of theproduct following a cus-tomer requirement. Usingmostly 6082 T6 anodizedaluminium alloy to build the arm, it weighs 12KG inwater, 4.5KG lighter than the original arm launched in2009. The upper arm has been designed with a sand-wiched closed cell foam core structure, adding buoyancy,and all component voids are retained as atmosphere airspaces as opposed to the more traditional oil filled andcompensated spaces. All these modifications have resultedin the weight of the arm being drastically reduced when inwater, and increased its stability when operating on anROV or AUV.
