offshore wind farm Borkum Riffgrund 2
Record performance for Germany
The 25 km2 wind farm area is located in the North Sea within the Exclusive Economic Zone (EEZ), approx. 34 km northwest of the island of Borkum and 57 km off the Dutch coast. The water depth there is about 25 to 30 m. The farm comprises 56 MHI Vestas V164-8.0 MW wind turbines and is the first wind farm in the German North Sea to be equipped with 8 MW wind turbines, making it the most powerful wind farm in German waters.The total capacity of the wind farm thus amounts to 450 MW. This means that around 460,000 German households can be supplied with green energy.
Innovative foundations
With a rotor diameter of 164 m, the turbines are to date the largest wind turbines in German waters and they are mounted on different types of steel foundations, as 36 foundations are monopiles (weighing 900 t and with a diameter of 8 m), their transition pieces weighing 400 t and having a diameter of 7.45 m, and the remaining 20 foundations suction bucket jackets (50 m high with a weight of 950 t).
Dillinger supplied in total around 40,800 t of mainly thermomechanically rolled heavy plate in thicknesses of 20 to 95 mm for both types of foundations.
