One of the largest in the world
With the offshore wind farm Gemini which went into operation in 2017, one of the largest offshore wind farms in the world, has its foundations on steel from Dillinger. Gemini (twins) stands for two sea areas in which the wind farm was erected in depths of water of up to 36 metres. With its site around 85 km north of the coast of the province of Groningen, it is located in one of the windiest areas off the Dutch coast.
The Gemini wind farm stretches over 68 km² and comprises a total of 150 wind turbines with an overall output of 600 MW. It is therefore currently among the most powerful wind farms worldwide and can supply over 400,000 households in the Netherlands with electricity. The turbines are based on monopile foundations that are up to 73 m in length and up to 7 m in diameter.
Dillinger supplied around 94,500 t of thermomechanically rolled plates with plate thicknesses of up to 95 mm for these steel foundations. With individual plate weights of up to 32 t, this gigantic project made full use of the huge production possibilities for TM plates, going to the limits of what was feasible at that time. Meanwhile, Dillinger can even supply these steels with individual plate weights of 35 t and is thus at the leading edge of this technology worldwide.
