Riffgrund foundations
GeoSea has just finalised the installation of 77 foundations on the DONG Energy Borkum Riffgrund 1 offshore wind farm. The installation works, including transport from the fabrication yard to the marshalling harbour, have finished ahead of schedule.
The 77 units consisted of monopiles, weighing between 495 tonnes and 684 tonnes and measuring a diameter of 5.9m and a length of up to 66m, and transition pieces weighing around 330 tonnes.
The installation vessel Pacific Orca, supplied by DONG Energy, is currently sailing to Flushing where GeoSea will start the mobilization works for the Suction Bucket Jacket, a new type of foundation also to be installed on the BKR1 field.
GeoSea’s sister company Tideway will continue with the scour protection installation works that are due to be finished soon. GeoSea is a fast growing company specialising in complex offshore marine engineering projects. The company is part of the Belgian DEME Group that is active across the globe. GeoSea has participated in the construction of large-scale offshore wind farms including the Alpha Ventus project, the EnBW Baltic 2 wind farm, the Trianel West Borkum II wind farm in German waters, the Walney wind farms and at the Ormonde farm in the Irish Sea and the C-Power wind farm off the Belgian Coast.
