Dutch surveyor Fugro has been awarded a contract to perform comprehensive geotechnical surveys for the eastern array of the Dogger Bank South (DBS) offshore wind farms.
The initiative is led by RWE and Masdar to develop one of the UK’s most powerful offshore wind energy projects. The detailed surveys will provide data on subsurface conditions at planned wind turbine locations, inter-array cable routes, and platform foundations.
Starting in mid-May, Fugro will mobilise multiple geotechnical vessels to carry out the fieldwork 122 km off the northeast coast of England.
This will include a range of techniques such as cone penetration tests, vibrocores, and sampling boreholes. Fugro will also use its SEACALF MkV Deep Drive system of seabed investigations for faster project delivery and reduced environmental impact.
This contract builds on previous work Fugro has completed for the DBS offshore wind farm, including preliminary geophysical and geotechnical investigations, a shallow geotechnical survey on the export cable route, and a detailed geotechnical investigation of DBS West.
“This year’s site investigation at the eastern array builds upon similar work completed at the western array in 2024. The DBS projects are critical infrastructure projects and have the potential to supply 3m homes with 3 GW of offshore wind generation capacity, supporting the UK Government’s clean power ambitions,” said Colin McAllister, development project lead for DBS offshore wind farms.
