Fugro

Fugro was awarded a contract by the Danish transmission system operator Energinet to undertake cable route surveys for Denmark’s North Sea Energy Island project. The work was aimed at de-risking the offshore and landfall export-cable corridor between the Danish landfalls and the planned artificial island location, providing geo-data to support subsequent engineering and future cable installation planning. Under the agreement, Fugro planned to mobilise dedicated survey vessels to site in March 2022 to execute a combined programme of geophysical and geotechnical investigations along the proposed cable route. The scope included remotely operated vehicle (ROV) inspections and shallow geotechnical investigations using Fugro’s Blue Snake system, which integrates cone penetration testing (CPT) and sampling in a single pass at fixed intervals. Fugro also included laboratory testing to characterise ground conditions and support understanding of ground engineering constraints. The survey deliverables were intended to improve data correlation and reduce uncertainty in route selection and cable protection/burial strategies, helping Energinet optimise design inputs and manage difficult metocean conditions during later construction activities. The assignment formed part of Energinet’s broader preliminary investigations supporting the phased build-out of an offshore hub distributing up to 10 GW of wind power from the North Sea to Denmark and neighbouring markets.
