DEME Group’s offshore marine engineering company GeoSea announced the start of the construction works for the offshore wind farm Nordsee One in the German North Sea.
The Nordsee One offshore wind farm (85 percent Northland Power – 15 percent RWE) is situated approximately 40 kilometers north of the island of Juist and consists of 54 wind turbines which will be installed in water depths ranging between 25 and 29 meters.
GeoSea’s T&I contract includes the installation of all monopile foundations and transition pieces. The execution of the project has already started with the installation of a first monopile. The entire project will be delivered over a schedule of six months.
The Nordsee One project will be executed by the world’s biggest jack-up vessel Innovation that recently completed construction of the nearby offshore wind farm Godewind. After some modifications in order to be prepared for the next challenge, the Innovation, sailing under German Flag with Bremen as port of registry, arrived at the port of Cuxhaven. Cuxhaven will serve as the base port from which the construction works will be executed.
With a length of 147.5 meters, a width of 44 meters and equipped with a Dynamic Positioning 2 (DP2) system, the self-propelled Jack-up vessel is sufficiently configured to efficiently execute offshore heavy-lifting operations and foundation installation works in challenging weather conditions.
The Nordsee One project consolidates GeoSea’s presence on the German offshore wind market following DEME’s acquisition of the Innovation and several other offshore assets from its long-term German partner Hochtief. The new project follows on participation in a series of other offshore wind farms in Germany (Godewind, Baltic II, Borkum Riffgrund, Amrumbank, Alpha Ventus and Borkum West II).
DEME Group is also investing through its subsidiary DEME Concessions Wind n.v. in the development of another German offshore wind farm Merkur, where preparations are in full swing.
