Germany, Karlsruhe: Construction work has begun on one of Germany’s largest offshore wind projects in the North Sea. The 960 MW He Dreiht offshore wind farm, worth €2.4 billion, is being developed by EnBW. The project is being built around 85 km north-west of Borkum and 110 km west of Helgoland.
More than 500 employees will work on the construction site, with over 60 ships involved. The first foundations in the seabed will be installed soon by the Thialf, one of the world’s largest floating cranes. A monopile – a 70-metre-long steel foundation, 9.2 metres in diameter and weighing around 1350 metric tons – will be used, after that, a transition piece will be placed.
The monopiles and transition pieces had previously been loaded onto floating platforms in Eemshaven in the Netherlands and towed to the construction site by tugboats. Work on installing the foundations will continue into the summer, while the 15 MW Vestas turbines and cables, to be installed and laid in early 2025, are being manufactured.
The project was secured in the first offshore auction held in Germany in 2017 and should go into operation at the end of 2025. EnBW will be responsible for the technical and commercial management, with servicing and maintenance work carried out from its Emden service base. TenneT will connect the project to the grid using an offshore converter station and two HVDC export cables, which will be laid over a distance of 120 km underwater and 110 km on land.
From the landfall point near Hilgenriedesiel, electricity will be transmitted by buried cable to the Garrel/Ost converter station in the Cloppenburg area. 49.9% of the shares in the project are owned by a partner consortium made up of Allianz Capital Partners, AIP and Norges Bank Investment Management.
