EnBW has completed ground investigations for the planned Dreekant offshore wind farm to assess seabed conditions for turbine foundations.
The company said Geoquip Marine Operations AG carried out cone penetration tests to determine the bearing capacity and composition of the seabed at turbine locations.
EnBW added that additional geophysical surveys were undertaken before the work to ensure no ordnance was present at borehole sites.
The developer noted that the data gathered will support foundation design, confirming that monopiles can be used despite soft top soil layers.
The Dreekant offshore wind farm is planned to be located 120km northwest of Heligoland and is scheduled to go online in 2032.
With a total capacity of 1GW, the project is expected to generate enough electricity to meet the needs of the equivalent of 1.35 million households.
Markus Lapke, project manager for Dreekant at EnBW, said: “The data obtained is essential for planning the foundations.
“We are pleased that it is possible to use monopiles as foundations despite the soft top soil layers.”
