REpower Systems has successfully erected two REpower 5M offshore wind turbines in the DEWI-OCC test field in Cuxhaven/Northern Germany.
The first completed turbine was built for the utility EWE AG (Oldenburg/Lower Saxony), the second one for the joint venture “EWC Windpark Cuxhaven GmbH” of E.ON Energy Projects GmbH (Munich) and Essent Wind Deutschland GmbH (Düsseldorf). Both turbines have a hub height of 117 metres and a rotor diameter of 126 metres. The nacelles with a helicopter abseil platform were manufactured in the J. Kramer shipyard in October in Bremerhaven and were shipped to Cuxhaven. Each turbine stands on five tower segments made of steel. The rotor blades, each 61.5 metres long, were transported by heavy-load trucks from Denmark to the building site; when spinning, they will cover an area of 12,469 square metres (corresponds to roughly the area of two football pitches). After the mounting of the hub on the ground, the rotor - which weighs about 120 tons - was hoisted up by a main crane and a support crane and connected with the rotor flange of the drive train in a height of 117 metres.
