Fugro completes surveys for Dogger Bank South

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 110km off the east coast of Yorkshire, England in the North Sea and has the potential to generate renewable electricity for up to 3.4 million UK homes per year. It has been divided into two areas, East and West. The array area covers approximately 1,000km2 with over 100km of proposed export cable routes, resulting in a total survey scope exceeding 20,000km 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 to be completed on a single project. 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.

The processed data will be shared on Fugro’s centralised cloud-hosted platform allowing internal and external teams access to authoritative project Geo-data.

Trevor Baker, RWE Project’s Lead for Dogger Bank South said: “The offshore surveys are a very important aspect of the project’s development and the data collected will help inform the environmental impact assessment process and help in the engineering design of the wind farms. Fugro have demonstrated technical competence in previous projects, and we are pleased to have them on board.”

Peter Aarts, Fugro’s Marine Geophysical Director Europe and Africa, said: “When considering a project of this scale, early access to Geo-data that provides actionable insights is key. With an understanding of the seafloor and sub-surface conditions, geohazards and environmental constraints, RWE will be able to make informed decisions on their wind farm foundation designs, whilst also reducing installation risks and ensuring the most efficient cable routes. We’re proud to support the future developmental phases of the Dogger Bank South wind farm project and the UK’s ongoing energy transition.”
