Ndeavor Recommissioning Rottterdam Offshore Group (ROG) based in the Waalhaven, Rotterdam recently completed the conversion of the multi purpose vessel (MPV) Ndeavor for Boskalis. The vessel was built in 2013 and is 99m in length with a beam of 30m, her gross tonnage is 7413T.
The vessel had been equipped for the last 2 years with rock dumping equipment. This included 8 stone holds weighing 180T each, which had to be removed as part of the demobilisation. These stone holds were lifted off the vessel utilising the floating sheerleg crane ‘Taklift 4’ from Boskalis, which itself, is capable of lifting 2200T.
This formed one part of the complex process to completely clear the aft deck to allow it to be fully reinstated. Once this was complete, ROG started the process of converting the Ndeavor to become a cable laying vessel.
The conversion was an extensive exercise which included installing new equipment including a new 200T knuckle boom crane, a 15T standalone crane, an 18-meter diameter 227T carousel to store the cable, a Trencher, HPU’s, control centres, boatlandings and additional equipment to guide the cable.
The whole project was managed by ROG and all work was carried out to the highest quality and safety standards whilst working to ensure completion of the project within the 8-week project timescale. The completed vessel left the yard, to start operations on its first cable laying project, the Inter Array Cable Installation works on 20 the Sandbank Offshore Windfarm 21

The MAD vessels are expected to be well received by an aggregate industry facing rising demand and an aging fleet.
Designed in collaboration with Maritime Design and Engineering Services (MD&ES), the MAD 4000 and 5600 are additions to Damen’s Trailing Suction Hopper Dredging portfolio. For offshore aggregate operations, the new vessels will be able to work in North Sea conditions up to depths of -60m. These capabilities allow operators to mine sand and gravel in deeper waters, farther from shore than preceding models.
Damen has invested considerably in research and development for the new MAD vessels, having observed an increase in demand for civil construction supplies deriving from an overall improving economy. The development aims at offering industry advanced technology, well suited to existing ports and delivering more uptime at sea.
Unlike traditional dredgers, the bow shape of the MAD vessels allows them to operate in adverse weather conditions. The shape is based on a proven Damen design applied to renowned vessels such as the Damen Offshore Carrier (DOC) and Platform Supply Vessel (PSV). In addition to improved seakeeping behaviour, the bow shape also protects the sand and gravel cargo from green water ingress.
The MAD vessels have been developed 24 with tomorrow in mind, states Mr. Marcus: 25 “These vessels are future proof. Featuring

Standardised the design may well be, but it is also versatile and takes into account the need for customisation and multi-role functionality. “A number of options exist in order to cater to differing client needs,” states Mr. Marcus.
“The vessel can be supplied with bottom doors if required – which will offer additional versatility in case it is required to perform differing operations. It can 26 also receive spud poles, for example. And, should the 27 client wish to scale up at any point, the MAD 4,000 can easily be converted into a MAD 5,600 with a simple section addition.”

UT3 Issue 6 Dec 2016 Jan 2017 UT3 Issue 6 Dec 2016 Jan 2017 Linear Winches ACP2 on the Connector
DeepOcean's newbuild advanced cable plough (ACP2) has been installed on the Maersk Connector, following build and mobilisation at the Port of Blyth. The spread will head out for offshore trials before export cable installation activities in the Irish Sea.
The Maersk Connector is an advanced flexible product installation vessel for HVAC, umbilicals and bundled HVDC power cable via its unique and innovative, dual basket 7000te capacity carousel. It is able to deliver all the capabilities of a DP2 installation vessel without sacrificing shallow water workability.
Equipped with a 7 point mooring system, the vessel can manoeuvre on a comprehensive anchor spread, allowing close approach for shore end installations. The vessel is certified to ground out fully loaded in suitable ground conditions for beach operations.
The vessel is now mobilised with the ACP2 cable plough, the first plough in the offshore industry fully designed for optimum performance in all areas, but specifically for the safe handling, burial and immediate backfill of large diameter power cables.
Incorporating an aggressive share design with multiple forecutters, the ACP2 is unique in its ability to accommodate up to 300mm diameter product with a 5m minimum bend radius and offer both on deck and seabed cable loading / unloading capability.
The plough offers variable depth control via hydraulically and Umbilicals actuated skids to enable safe burial from 0m to 3.3m. The plough has a powerful 325kW anti-cavitation jetting system capable of operating in water depth starting as little as 0.5m to reduce seabed resistance and tow loads.
Comprehensive instrumentation and surveillance for control and monitoring during ploughing is enhanced by a pivoting bellmouth that allows superior handling of the cable and a reduced cable wrap angle for product safety during launch and recovery. An industry proven mechanical link bridle system is utilised for efficient steering, whilst minimizing plough complexity.
50 The ACP2 utilises a sophisticated Launch and Recovery 51 system, using a hydraulically dampened, wide angle A-Frame and traversing carriage for superior control during

COBRACable Cable Buoyancy Modules TenneT and its Danish partner Energinet.dk have driven the first pile into the ground for the construction of the Dutch convertor station of the COBRAcable, a subsea electricity connection that will link the Dutch and Danish grids.
The COBRAcable will have a capacity of 700 MW, will be around 325km long, and will run from Eemshaven (Netherlands) to Endrup (Denmark) via the German sector of the North Sea. The connection will be constructed as a High-Voltage Direct Current (HVDC) cable, since the use of DC technology minimizes transmission losses over long distances and therefore virtually eliminates any loss of renewable electricity. Two onshore converter stations – one in the Netherlands and one in Denmark – are needed to connect the cable to the existing grids.
These stations will convert the electricity from direct to alternating current or vice versa (depending on the transmission direction), and will feed it into the Dutch or Danish onshore transmission grid in order to supply electricity to homes and businesses.
Siemens is responsible for constructing the electrical installations in the converter stations in the Netherlands and Denmark. The company will also undertake the civil engineering of the converter station in the Netherlands.
The COBRAcable is not the first subsea electricity connection constructed by TenneT. In 2008 the TSO completed the NorNed cable between the Netherlands and Norway (capacity: 700 MW, length: 580 km). This was BARDOT's buoyancy modules on Hywind followed in 2011 by the BritNed cable between the Netherlands and the UK BARDOT has been awarded by has chosen BARDOT Group to equip Optical Cables (capacity: 1,000 MW, length: 260 km).

UT3 Issue 6 Dec 2016 Jan 2017 UT3 Issue 6 Dec 2016 Jan 2017 Turk Stream South Stream Transport has awarded the Swiss-based Allseas Group a contract to lay the first line of the TurkStream offshore gas pipeline in the Black Sea, with an option for laying the second line. According to the contract, Allseas is to lay more than 900 km of pipes on the seabed.
Allseas will engage the world's largest construction vessel, the dynamically positioned Pioneering Spirit, for the job.Pioneering Spirit is equipped with pipelay equipment that makes it possible to install record- weight pipelines from shallow to ultra-deep water, and has an S-lay tension capacity of 2000 tonnes. The vessel, currently in the Alexiahaven in Rotterdam, is equipped with a double-joint factory, six welding stations for double joints and six coating stations.
Allseas will start laying the first line in the second half of 2017.
Pioneering Spirit is the largest construction vessel ever built. Inspired by the offshore heavy lifting pioneer Pieter Schelte Heerema (1908–81) and designed completely in-house, the vessel is designed for the single-lift installation and removal of large oil and gas platforms and the installation of record-weight pipelines.
The twin-hulled vessel is 382 m long and 124 m wide. At the bow is a slot, 122 m long and 59 m wide, that enables Pioneering Spirit to straddle a platform and remove entire topsides – up to 48,000 t – in a single lift using eight sets of horizontal lifting beams. Two tilting lift beams for the installation and removal of jackets – up to 25,000 t – will be located at the vessel’s stern. Complementing the lifting systems is a 5000 t special purpose crane for additional lifts such as lighter topsides and jackets, modules and bridges.
As a result of her unique lifting capacity,Pioneering Spirit will significantly reduce the amount of offshore work associated with platform installation or decommissioning, largely moving this work to shore, where it is cheaper, safer and more environmentally friendly.
Pioneering Spirit’s large ship size gives her very good wave response behaviour, superior to semi-submersible crane vessels in operational wave conditions; topsides and jackets can be installed or removed in significant wave heights of up to 3.5 m. While the vessel moves due to wave action, all motions relative to the platform are eliminated by engaging the active motion compensation system, which enables Pioneering Spirit to make large lifts in hostile seas.
The ship can sail under her own power at a high transit speed, making her suitable for worldwide use. Operating on full dynamic positioning, she can work accurately in any water depth, while her light ice class will extend the periods in which she can operate in Polar Regions.
Pioneering Spirit is also equipped with pipelay equipment that makes it possible to install record-weight pipelines from shallow to ultra-deep water, and achieve high lay rates. With an S-lay tension capacity of 2000 t, she surpasses Solitaire as the world's largest pipelay vessel. 58 59

Ardent completed removing the Troll Solution jack-up in late 2016. Weighing approximately 7000t, the jack-up experienced a debilitating accident while carrying out maintenance work on the wellhead platform CAAN-A in 2015.
The Troll Solution collapsed and sank into the seabed in approximately 30m water depth. After sinking, it came to rest within 2m from the active CAAN-A platform. Prior to Ardent’s involvement, efforts were made to refloat and salvage the jack-up.
Ardent deployed assets from several countries, including the Conquest MB-1 crane barge, and a 1,000-ton hydraulic wreck grab from the Netherlands. Further support vessels were deployed from the U.S. and Mexico.
The Conquest MB-1, with a maximum of 1,400 tons lifting capacity has been previously deployed under Titan, Ardent’s pre-merger company, in support of the Costa Concordia removal in Italy.
The operation used Ardent’s newly designed Guided Guillotine to dismember the jack-up, instead of cutting with more conventional methods.
“Traditional methods require either a push or pull-cut with chains or diamond wire. Pull-cuts require tunnels to be bored into the seabed, whereas push-cuts require a large framework to be built around,” said Ardent Naval Architect Roland De Marco.
“The main hurdles to overcome were, how to best cut the jack-up into sections without fabricating an elaborate structure, and boring holes underneath the jack-up through the seabed was improbable due to obstructions,” said Shelby Harris, Ardent Americas Operations Director.
“We had to apply ingenuity to use our chain cutting techniques on the deck house in a less than conventional method, and the Ardent Guided Guillotine sectioned the hull. The method worked very well,” said Harris.
Conventional guillotine cutters are restricted to operations above the surface. The Ardent Guided Guillotine can function underwater with the precision to cut the Troll Solution jack- up into the required lift pieces.
The Ardent salvage team cut the deck house into 6 pieces with Ardent Chain Pullers, and the vessel’s hull into 31 pieces 62 with the Ardent Guided Guillotine and subsequently lifted 63 these from the seabed with the Conquest MB-1 crane barge.

UT3 Issue 6 Dec 2016 Jan 2017 UT3 Issue 6 Dec 2016 Jan 2017 Renewables US$40million Wave Test Facility
Oregon State University’s Northwest National Marine Renewable Energy Center today was awarded up to $40 million from the U.S. Department of Energy, to create the world’s premier wave energy test facility in Newport.
The NNMREC facility, known as the Pacific Marine Energy Center South Energy Test Site, or PMEC-SETS, is planned to be operational by 2020. It will be able to test wave energy “converters” that harness the energy of ocean waves and turn it into electricity. Companies around the world are already anticipating construction of the new facility to test and perfect their technologies, OSU officials say.
“These devices have to perform in hostile ocean conditions; stand up to a 100-year storm; be energy efficient, durable, environmentally benign – and perhaps most important, cost-competitive with other energy sources,” said Belinda Batten, the director of NNMREC and a professor in the OSU College of Engineering. “This facility will help answer all of those questions, and is literally the last step before commercialization.”
In making the award, the agency noted that more than 50 percent of the U.S. population lives within 50 miles of coastlines, offering America the potential to develop a domestic wave energy industry that could help provide reliable power to coastal regions. Investments in marine and hydrokinetic energy technology will encourage domestic manufacturing, create jobs, and advance this 86 technology to help achieve the 87 nation’s energy goals, DOE officials said in their announcement of this award.
