Dillinger heavy plate for the
Baltic 2 offshore wind farm

The offshore wind farm, officially inaugurated in September 2015, is able to generate 1.2TWh of electricity a year, sufficient to supply approximately 340,000 German households with eco-friendly electricity. So it makes a decisive contribution to save over 900,000 tons of CO₂ every year.

With its 80 Siemens SWT-3.6-120 turbines erected in the waves of the Baltic Sea, the wind farm covers an area of almost 27 km², making it the largest offshore wind farm in the Baltic Sea area. The wind turbines rising 138 m above the surface of the water are almost as tall as the Cheops Pyramid in Giza.

Its location in the German exclusive economic zone (EEZ), 32 km north of the island Rügen, with variing water depths between 23 and 44 m and difficult soil conditions presented a new challenge for the wind farm developers.
Finally, depending on the water depth, the wind turbines have been erected on different foundations. Monopiles have been used for water depths up to 35 m, while three-legged jackets have been utilized at depths over 35 m.

For the monopile and jackets foundations Dillinger supplied around 37,700 t of thermo-mechanically rolled heavy plates (S355ML, S420ML, S355G10+M) in thicknesses from 20 to 85 mm.
