Heavy plate from Dillinger for one of the world's largest offshore wind farms: official opening of the Hollandse Kust Zuid

The Hollandse Kust Zuid 1-4 offshore wind farm has celebrated its official opening. The wind farm is located between 18 and 36 kilometers into the North Sea off the Dutch coast, between the cities of Scheveningen and Zandvoort.

The farm is built on monopile foundations stretching 62 to 75 meters long and weighing up to 955 tons, in water depths reaching 17 to 28 meters. Dillinger supplied around 115,000 tons of heavy plate for these monopile foundation structures in thicknesses ranging from 54 to 90 mm.

“We are proud to provide an important contribution with our products to another offshore wind farm project and thus to the energy transition,” said Danny van der Hout, Dillinger's Chief Sales Officer. “With our highly advanced production processes and wide-ranging service system, we are helping our customers continue accelerating the expansion of green energy.”

With 139 turbines and an installed capacity of 1.5 GW, Hollandse Kust Zuid is one of the largest offshore wind farms in the world. It can supply approximately 1.5 million households with renewable energy each year.

During construction of Hollandse Kust Zuid 1-4, the natural surroundings were also included for the first time in the design of the wind farm. These measures include enlarged water holes in the foundation elements that provide shelter for marine life inside the turbines as well as boulders and stones of various sizes that were used to construct the scour protection. Artificial rocky reefs have been created on several scour protection systems to make them more attractive to a greater number of fish, crabs, and crustaceans.
