RWE and Masdar have commissioned global leading geo-data specialist Fugro to undertake detailed geotechnical surveys on the site of two Dogger Bank wind farms more than 100km off the UK in the North Sea.
Three vessels, Fugro Quest, Fugro Voyager and Normand Mermaid, will survey the ground conditions below seabed from June to October this year at the location of each proposed turbine and platform foundation, and associated seabed infrastructure. The ground investigation will use a combination of Cone Penetration Tests and sampling boreholes and will be an extensive geotechnical campaign for one of the world’s largest offshore wind projects.
Colin McAllister, Development Project Manager, DBS offshore wind farms said: “The geotechnical data from these site investigations will give our engineers a detailed and accurate picture of the individual ground conditions at sites of the foundations and associated offshore infrastructure. We already have high-level data about the seabed conditions from reconnaissance surveys conducted in 2022. With the level of detail captured from the new surveys, however, we can design the most effective foundations for each turbine and platform in the project. We expect similar detailed surveys to take place at DBS East in the future.”
John ten Hoope, Fugro’s Regional Director Marine Site Characterisation said: “We are excited to continue working with RWE on this prestigious project. Our successful combination of innovation technology and expert project teams will safely deliver timely high-quality data and insights crucial to optimising the design of DBS West offshore wind farm. The fieldwork, which comprises seabed cone penetration tests, and vibrocores from the Normand Mermaid and geotechnical boreholes from the Fugro Quest and Fugro Voyager, will start in June 2024. The subsequent extensive laboratory testing will take place in Fugro’s laboratories in the UK.”
