Hamburg, Germany [RenewableEnergyWorld.com] REpower Systems AG has completed build out of the first wind farm exclusively using the REpower 6M turbines, each of which has a rated capacity of 6-megawatts (MW). The three turbines, installed in the Westre civic wind farm close to the German-Danish border, each have a rotor diameter of 126 meters, making them some of the biggest wind turbines in the world.
The new turbine was developed by REpower engineers for offshore deployment at a later stage and assembled at the company’s manufacturing centre in Bremerhaven. In January, the nacelles of the three 6Ms were shipped from the REpower plant in Bremerhaven to Dagebüll in Schleswig-Holstein and transported to the construction site from there.
The rotor blades, each one 61.5 metres in length, were transported as a wide load directly from Denmark. The hub height of a 6M at the Westre civic wind farm comes to 100 metres. A crane with a boom height of 132 meters assisted in erecting the turbines.
“By now, the REpower team has gained experience in the installation of 17 turbines of the type REpower 5M; the 6M technology is based on the successful 5M construction series. However, this was still our first time erecting a wind farm that consists fully of turbines each with a six megawatt output and for this I congratulate the entire project team. This achievement means we have once again taken one huge step forward in the field of offshore wind energy,” said Matthias Schubert, CTO of REpower.
