Fugro has secured a contract with Energinet to undertake cable route surveys for Denmark’s North Sea Energy Island project. The Energy Island will serve as an offshore power plant, a hub distributing up to 10 GW of offshore wind energy 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.
Fugro’s survey vessels will be on site in March 2022 to begin the geophysical and geotechnical surveys. This will include remotely operated vehicle (ROV) inspections and shallow geotechnical investigations using the company’s Blue Snake geotechnical system. This 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. It employs a high performance vibrocorer and 10 ton CPT into a single frame with a customised launch and recovery system – thus minimising manual handling and improving workability in difficult weather conditions.
This Energy Island contract follows on from two geotechnical site investigation contracts and a marine site characterisation contract already awarded to Fugro, which is also supplying Energinet with wind-resource mapping after installing and operating wind lidar buoys in the Baltic Sea and the North Sea.
