Sassnitz (dpa/mv) - The first foundation for the Arcadis Ost 1 offshore wind farm has been installed off Rügen. The companies Parkwind and DEME Offshore announced on Wednesday that it was a 2,100-ton steel pile with a diameter of 9.5 meters and a length of 110 meters. The pile is one of the largest of its kind ever installed. In the coming weeks, 27 more foundations are to be installed in the seabed off the coast of Rügen.
A special feature of the installation is the use of a floating crane instead of ships that connect to the seabed with legs. According to the companies, it should be possible to install faster and also in areas where this was not previously possible. The special ship "Orion" is used. It was fitted with a new crane by Liebherr in Rostock after the crane on board the ship was damaged and snapped during a test in early May 2020.
Arcadis Ost 1 is scheduled to go into operation in 2023 and have an output of 257 megawatts. The wind farm should be able to supply electricity for almost 300,000 households. 27 wind turbines will be installed off Rügen for this purpose. The foundation that has now been installed is intended to support the offshore substation of the wind farm.
