GeoSea to design, manufacture and install turbine foundations
Belgian marine construction major DEME Group’s offshore marine engineering subsidiary GeoSea will design, manufacture and install 71 turbine foundations for the EnBW Hohe See offshore wind farm, for which GeoSea is Siemens’ EPCI partner.
This partnership enables Siemens to provide offshore wind turbines including foundations to EnBW.
The design certification for the monopile and transition piece foundations was obtained at the end of 2016, fabrication will take place in 2017 while offshore installation will take place in 2018.
The EnBW Hohe See offshore wind farm is situated approx. 90km north of the island of Borkum in the German North Sea. The project will cover an area of around 40 square kilometres with water depths of up to 40m. Hohe See will have a total installed capacity of 497MW and feature 71 Siemens SWT-7.0-154 turbines. The wind farm will supply energy to about 560,000 households and save around 1.5 million tonnes of CO2 per year.
Financial close for Hohe See was announced on February 17, 2017.
