Fugro reveals new contract on Norfolk Boreas

Vattenfall has awarded Furgro a new contract for marine site investigations on its Norfolk Boreas offshore wind farm. The 1.4 GW project, located off the east coast of England, is expected to generate enough power for 1.5 million UK homes, and forms part of Vattenfall’s Norfolk Zone. Fugro has previously conducted a four-month marine site characterisation campaign, back in 2020.

This August, Fugro will complete full coverage surveys across the wind farm area, inter-array cables and export cable routes, mobilising geophysical and geotechnical vessels from local ports. Operations will involve Fugro’s SEACALF® Mk V DeepDrive® system for seabed cone penetration tests (CPTs) and Fugro’s Blue Snake™ geotechnical system, which integrates CPT and sampling technology to enable safe, efficient, high-quality data acquisition along the cable route.

The project’s first phase will see geophysical surveys and unexploded ordnance (UXO) surveys, then a 2D ultra high-resolution seismic (UHRS) survey to provide detailed seabed and shallow sub-surface information. Geodata that is collected will support the positioning of inter-array cables, in addition to facilitating route planning, helping improve project design, and enhancing safety for future operations.

After fieldwork, there will be an extensive laboratory testing programme, from Fugro’s UK laboratories in Wallingford and Consett, with support from its newly certified and accredited laboratory in Belgium. Resulting geodata will feed into the Norfolk Vanguard and Norfolk Boreas projects’ ground model, to optimise foundation and cable design.
