Fugro has secured a contract to carry out comprehensive geotechnical surveys for TotalEnergies’ 2GW NordSee Energies 1 offshore wind farm.
The work on the North Sea N-12.1 site includes investigations at planned wind turbine locations and inter-array cable routes, the company said.
Fugro added that fieldwork is already under way using five specialist vessels about 170km off the German coast across an area of around 200km2.
The campaign covers about 140 locations and reaches depths of up to 50 metres below the seabed using technologies including the SEACALF Mk V seabed cone penetration testing system.
According to Fugro, subsequent laboratory testing will take place at its facilities in Wallingford in the UK and Louvain in Belgium.
The resulting Geo-data will be delivered through VirGeo, Fugro’s cloud-based Geo-data platform, and used to understand soil behaviour and inform the design, installation and protection of the inter-array cables.
“With a five-vessel programme, this is one of the largest offshore wind investigations we’ve undertaken in Europe,” said Remmelt de Jong, Fugro’s regional business line director for marine site characterisation in Europe and Africa.
“By combining advanced technology with expert analysis, we’re ensuring TotalEnergies receives the foundation data needed to keep this project on schedule and support Europe’s clean energy ambitions.”
TotalEnergies was awarded concessions by the German Federal Network Agency in 2023, 2024 and 2025 for the construction of four wind farms in the North and Baltic Seas and is participating in two offshore wind projects with RWE, resulting in an awarded offshore wind pipeline of 7.5GW.
