RWE Innogy awards contract for wind turbine installation vesselVessel & ROV News // December 7, 2009
DSME is due to delivery RWE Innogy's first newbuild in 2011.
RWE Innogy has awarded Korean shipyard Daewoo Shipbuilding & Marine Engineering Co Ltd (DSME) a contract to build a specialist ship for the construction of offshore windfarms. The contract also includes the option for two further identical construction ships. The value of the contract for each ship is around Euros 100 million. The first ship should be completed in 2011.
Professor Fritz Vahrenholt, Chairman of the Board of Directors of RWE Innogy GmbH, said: "The building of our own construction ships will overcome one of the most important supply bottlenecks we face in the construction of windfarms at sea. These ships will give us a decisive time and cost advantage in the North Sea and further afield in implementing our ambitious plans to expand wind energy.“
The ships ordered by RWE Innogy are the first of their type in the world. They are able to transport and install the largest available offshore wind turbines including foundations.
With a length of 109m and a breadth of 40m, the ships can simultaneously transport and install up to four turbines in the multi-megawatt class. Fitted with DP positioning systems, the ships can be poisitoned with a very high level of accuracy for construction work at sea and operate in water depths of more than 40m.
"The construction ships of this special design are ideally suited to the construction of marine wind power plants. Unlike the vessels which were previously used, they are able to successfully install the largest wind turbines currently available in the 5-6MW class even under the harsh conditions which are often encountered offshore,“ Professor Martin Skiba, Head of Offshore Wind at RWE Innogy, explained.
The ships are intended for use in the construction of the offshore windfarms planned by RWE Innogy. The company currently has plans for two windfarms in the German part of the North Sea, North Sea East (295MW) and Innogy North Sea 1 (960MW). Of the Welsh coast, RWE Innogy is planning construction of an offshore windfarm to be called Gwynt y Môr (576MW).
