Wind turbines in generalOffshore Wind Power Plants (WPP) built in the North Sea must be very powerful, efficient, and simultaneously need to be easy to be maintained. Due to the long distances to the shore, the Offshore Wind Turbine Generators (WTG) have been fitted professionally to withstand heaviest weather conditions.
In the Offshore WPP Nordsee One, 54 WTGs of Senvion SE 6.2M126 are in operation. The WTGs have a height of ~152 m over the lowest astronomical tide (LAT).
The Senvion 6.2M126 is a variable speed WTG with a nominal power of 6.15 MW. It has a rotor diameter of 126 m and an electrical, single-blade pitch system.
