Korean shipyard Daewoo Shipbuilding has won a contract to build a specialist ship for RWE Innogy to be used for the construction of offshore wind farms.

The contract also includes the option for two further identical construction ships worth $148m each.

RWE Innogy expects the first ship to be completed in 2011.

The ships can simultaneously transport and install up to four turbines in the multi-megawatt class.

Featuring satellite control, the ships can be fixed with centimetre-precision for construction work at sea and operate in water depths of more than 40m.

RWE Innogy said it has plans for two wind farms in the German part of the North Sea.
