Fugro wins survey contract for Denmark’s energy island

Fugro has been awarded a new contract by Danish TSO Energinet to undertake cable route surveys for the North Sea Energy Island which will serve as an offshore power plant distributing up to 10 GW of offshore wind to Denmark and other neighbouring markets.

Fugro will perform a combination of geophysical, geotechnical services and laboratory testing to provide insight into the ground engineering challenges along the cable route from the Danish landfalls to the future artificial island location.

Blue Snake geotechnical system

Fugro’s dedicated survey vessels will mobilise to site in March 2022 to begin the geophysical and geotechnical surveys. This will include remotely operated vehicle (ROV) inspections and shallow geotechnical investigations using Fugro’s innovative Blue Snake geotechnical system. The Blue Snake integrates cone penetration testing (CPT) and sampling technology to enable data to be captured in a single pass with testing completed consecutively at fixed distances along the cable route.

The system integrates a high performance vibrocorer and 10 ton CPT into a single frame with a customised launch and recovery system – minimising manual handling and improving workability in difficult weather conditions. This innovative technology optimises data correlation, improving design and engineering for future cable installation works.

The Energy Island contract follows on from two geotechnical site investigation contracts as well as a marine site characterisation contract awarded to Fugro at the end of 2021. Fugro is also supporting Energinet with wind-resource mapping after installing and operating wind lidar buoys in both the Baltic Sea and North Sea. Source: Fugro
