Germany’s largest offshore wind farm under construction, EnBW’s He Dreiht, just hit a big milestone: The first enormous turbine is now up in the North Sea.
He Dreiht – which means “it spins” in Low German – is using Vestas’s massive 15 megawatt (MW) turbines, the first project in the world to install them.
He Dreiht is located about 85 kilometers (53 miles) northwest of Borkum and 110 kilometers (68 miles) west of Helgoland. At peak times, more than 500 workers will be out at sea building the farm, using a fleet of more than 60 ships. EnBW’s offshore team in Hamburg is running the show.
The installation process is a major operation. The 64 foundations were already set in the seabed last year. Parts for the turbines are loaded onto the installation vessel Wind Orca in Esbjerg, Denmark, and shipped out in a 12-hour journey to the construction site. From there, the turbines are lifted into place. Meanwhile, crews are also working on internal wind farm cabling.
