Renewables Wind Turbine Installation Vessel

GustoMSC is to build a wind turbine installation jack-up vessel for an undisclosed client. It will be the largest of its kind serving the wind turbine Installation market. The NG-9000CHPE is intended for use in water depths of up to 45m in a North Sea environment. The vessel will be able to undertake high speed fully loaded voyages to the installation site. She is equipped with a DP-2 dynamic positioning system for positioning at site.

An accommodation deckhouse suitable for 90 persons is located on the forward end of the vessel. A helicopter landing deck suitable for a Sikorsky S92/ S61N or Super Puma AS 332L2 is provided on top of the accommodation deckhouse. Central to its operation is a 800t heavy duty offshore crane developed by GustoMSC. The GLC-800ED crane combines a high capacity & high outreach with a short minimum radius, is located on top of the portside aft jack-house and revolves 360deg unrestricted around the leg. The four legs with the continuous speed GustoMSC jacking system

and the diagonal pre-loading allow for easy and fast installation. Propulsion for transit is provided by three propulsion azimuth thrusters of 3500kW, together with another three tunnel thrusters of 1750 kW. These provide thrust for station keeping with a DP-2 dynamic positioning system. Transit speed approximately 12 kts. The main deck is locally reinforced for the transportation of wind turbine parts or other heavy components. In addition the vessel has the ability to work in the offshore oil and gas sector. The vessel features a 6,500 ton variable load capacity. The vessel is equipped with the GustoMSC 9000C continuous hydraulic positive engagement jacking system. It has a maximum jacking capacity of 5300t ft per leg and a maximum holding capacity of 9000t ft per leg. The delivery is scheduled for early 2012. This project is a continuation of a cooperation between DDW-SEA and GustoMSC. Since 2005, it has designed and built four SEA-2000 construction jack-ups, four CJ46-X100D drilling jack-ups, two service jack construction / decommissioning jack-ups and one SEA-2750 multi-purpose jack-up.
