TotalEnergies has contracted Fugro to perform geotechnical surveys for the NordSee Energies 1 (NSE1) offshore wind farm at the N-12.1 site in Germany, where survey work is already underway.
Investigations will be carried out at around 140 locations, reaching depths of up to 50 metres below the seabed.
The geotechnical surveys will provide essential insights into seabed conditions at planned wind turbine locations and inter-array cable routes, directly informing the safe and efficient design of turbine foundations, according to Fugro, which is mobilising a fleet of five specialist vessels for the campaign.
The company said it was also deploying advanced technologies for the work, including its SEACALF Mk V seabed cone penetration testing system. The subsequent laboratory testing programme will be carried out at Fugro’s laboratories in Wallingford, UK, and Louvain, Belgium.
“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 the rights for the N-12.1 site at the German offshore wind tender in 2023, when the developer secured the area with a bid value of EUR 1.875 million/MW (EUR 3.75 billion total).
