Heavy plate from Dillinger for the offshore wind farms Borssele III and IV

The Borssele offshore wind field is located around 22 km off the coast of the Dutch province of Zeeland. It covers an area of 122 km², it is divided into four wind farms of approximately equal size, each with about 350 MW, and a fifth, much smaller area (20 MW) for innovative experimental purposes. The water depths vary between 14 and 38 m. With an output of around 1,400 MW, it will be, after completion of all five parts, to date the largest wind field in the Netherlands.

The 77 wind turbines installed on the two fields Borssele III and IV will supply around 825,000 Dutch households with environmentally friendly electricity and save over 1 million tons of CO₂ each year.

The 77 MHI Vestas V164-9.5 MW turbines are founded on monopiles. Here, TM record plates with individual plate weights > 40 t were used in large quantities for the monopile foundations, which optimized fabrication in terms of welding and handling. Each monopile is 85 m long and weighs 1,280 t.

For these monopile foundation structures, Dillinger supplied approximately 69,620 t of heavy plate in grades S355G7+M, S355G8+M, S355ML, S460G2+M and S460ML in thicknesses ranging from 12.7 to 88 mm.
