12 TH VOLUME, NO. 48 DATED 04 DECEMBER 2010 efficiency and operational range and rely heavily on Incat Crowther's experience from earlier designs. The increased size over previous Incat Crowther designs allows for extra passenger comfort and space as well as 14 tonnes of cargo capacity." The vessels have been designed by Incat Crowther in accordance with Det Norske Veritas/+1A1-HSLC-R2 Wind Farm service 1 rules, UK MCA SCV, Category 2 and are compliant with German Flag State requirements. The vessels will be equipped with twin MTU 8V2000 M72 engines (720 kW each), which will allow them to reach a maximum speed of 31 knots and a service speed of 26,5 knots at 85 percent MCR. The first boat will be delivered early May 2012 with each subsequent vessel delivering at 1.5 month intervals. The BLRT Marketex shipyardoffers advanced solutions for small vessels building as well as for large sized projects in steel, stainless steel and aluminum. The company has more than 10 years of experience in manufacturing of feeding barges for fish industry, service catamarans, complex components for the offshore oil and gas production sector and offshore wind industry. BLRT Marketex is a subsidiary of Estonia's BLRT Grupp. (Source: MarineLog) NORWIND, ULSTEIN TO DEVELOP NEW INSTALLATION VESSEL FOR OFFSHORE WIND INDUSTRY Norwegian based NorWind Installer contracted the ULSTEIN Dutch design offices Ulstein Sea of Solutions and Ulstein IDEA Equipment Solutions as their design partners for a new foundation installation vessel for the offshore wind industry. The vessel is a customized version of the Deepwater Enabler design from ULSTEIN. The DP vessel is designed for world-wide operations with a focus on pre-piling and jacket/tripod/transition piece installation for the offshore wind industry in North Europe. Different deck layouts, based upon NorWind Installer’s installation experience from Alpha Ventus, have been developed for the various installation modes on top of the generic vessel platform provided by ULSTEIN. The approach for this design has been unique in the sense that NorWind Installer and ULSTEIN started this project by going through the ULSTEIN Accelerated Business Development process. Technical and operational options from both NorWind Installer and ULSTEIN were discussed in a transparent process resulting in the most viable option, which met NorWind Installer’s business model and requirements. ”We are pleased with the concept as it is definitely in line with our vision of combining state-of-the-art technical solutions with the speed and seakeeping capacity of DP vessels. It gives us the opportunity to provide our installation services all-year around in up to 2.5m Hs, as well as meeting our client’s cost targets”, states Thorbjørn Hansen, VP Product Development at NorWind Installer. The vessel is designed aiming for maximum efficiency and cost effectiveness and features an 800t heave compensated offshore crane on starboard side, while a prepiling template can be located on a support structure at the stern. The vessel can carry four jackets, alternatively at least 24 piles or up to 12 transition pieces on the large open aft deck. To enhance vessel operability, the anti-heeling system has been designed in such a way that the main crane can revolve over 180o with a full load in its main hook within 5 minutes, which is very favourable having a large jacket in the crane hook. When operating in the pre-piling mode, the pre-piling 18/24
12 TH VOLUME, NO. 48 DATED 04 DECEMBER 2010 template is positioned on the seabed by the main crane, in parallell a pile is picked up by a gantry crane, put in the upending frame on starboard side and upended. The main crane has been modified by ULSTEIN in such a way that it can first pick-up the piling hammer with its main hook and then connect to the upended pile with its auxiliary hook. When the hammer is working on driving the pile into the seabed, the next pile is upended by the upending frame and made ready for crane lift out. The large aft deck and AHC crane provide flexibility for serving alternative subsea and offshore markets in the future, which is further increased by the two large holds suitable for carroussels located below main deck. A deck layout version of the vessel has also been developed for tidal turbine installations. Voith Schneider propellers of 3,900 kW each will allow for a cruising speed of 13 knots and enhance the DP capabilities of the vessel. To minimize the environmental footprint an NOx reduction system is installed in the exhaust lines. “After working closely with NorWind Installer in the ABD process, ULSTEIN started developing the integrated concept for mission equipment and vessel. This project shows the combined strength we can offer to support our clients in realizing their visions”, says Edwin van Leeuwen, project manager at ULSTEIN. (Source: Ulstein) SEAZIP OFFSHORE SERVICE SIGNS CONTRACT TODAY FOR 2 DAMEN TWIN AXES FOR OFFSHORE WIND FARM MAINTENANCE Damen Shipyards and SeaZip Offshore Service will sign a contract at the EWEA conference (14:30 hrs, stand 11020, Amsterdam, The Netherlands,). SeaZip has ordered two Fast Crew Suppliers of the 2610-type. The first ever FCS 2610 was delivered early 2011 and offers reduced peak accelerations of up to 75%, reduced added resistance in waves of up to 60% and has already transferred maintenance crew to turbines in wave heights of 1.9 m. Jan Reier Arends, one of Seazip’s Managing Directors, will sign the contract with Roel van Eijle, Sales Manager Benelux, on the first day of the 2011 Offshore conference of the European Wind Energy Association. The vessels will be built at Damen Shipyards Singapore and delivery is set for the third quarter of 2012. Safe access to offshore sites: Offshore wind is rapidly becoming a highly a specialized field in offshore operations. As the need for specialized services grows, there’s a need for fit-for-purpose service vessels. That’s why Mr Arends and Mr Sander Schakelaar, managing owners of the established (container) transport company JR Shipping, founded SeaZip Offshore Service in 2010. SeaZip will draw on the 18 years of experience and services of JR Shipping, including vessel development and management. The two entrepreneurs have a clear goal: to provide service vessels for fast and safe access to offshore sites. In their effort to deliver “outstanding and safe performance in even the most challenging of circumstances” (SeaZip’s mission statement), they teamed-up with Damen Shipyards. The FCS 2610, already in use at offshore wind farms, matched Seazip´s requirements as to safety, transport capacity, comfort, and performance levels in harsh weather conditions. Another argument is that offshore wind farms are being built at ever-increasing distances from the shore, impairing continuity in operations and maintenance. The FCS 2610 can overcome these challenges as it has a range over 1000 nm, a 20,000 litre fuel tank (for sailing and transferring purposes) and there’s accommodation for 4 crew and 12 industrial personnel.
