Fugro has completed fieldwork on a geophysical, geotechnical and environmental site investigation contract for RWE Renewables’ Dogger Bank South (DBS) offshore wind farm and export cable routes.DBS is located more than 110 km off the east coast of Yorkshire, England in the North Sea. The array area covers approximately 1,000 km2 with over 100 km of proposed export cable routes, resulting in a total survey scope exceeding 20,000 km of survey lines. Fugro mobilised multiple vessels from its fleet to complete full coverage surveys. This included seabed cone penetration tests (CPTs), sampling boreholes, multibeam echosounder surveys and the largest 2D ultra high-resolution seismic (UHRS) survey. In addition to this, Fugro’s environmental surveys comprised of grab sampling, epibenthic trawling and drop-down videos. The acquired geo-data will be used to understand the site’s subsurface conditions, advise on geohazard risk mitigation and identify a safe route for export cables.
