Fugro

Fugro completed a cable route survey for the Hollandse Kust Zuid offshore wind farm grid connection for client TenneT. The scope covered offshore route corridor investigation to support the planned export cable route to the HKZ wind farm area in the Dutch North Sea, with the work focused on collecting and interpreting seabed and sub-seabed data needed to confirm route feasibility and constraints. A key element of the campaign was unexploded ordnance (UXO) risk mitigation. Fugro carried out a search for UXO and other potential hazards along the cable corridor using a remotely operated towed vehicle and complementary survey equipment. The survey identified more than 3,600 potential targets of interest. Following data interpretation, Fugro progressed to investigate more than 700 potential UXO targets using its UXO identification vessel Atlantis Dweller. After the investigation and confirmation activities were completed, TenneT received a final UXO clearance certificate for the route corridor. This work supported TenneT’s development of the offshore grid connection required to bring power from the HKZ wind farm to the Dutch onshore transmission network by reducing seabed risk and improving confidence in the selected cable corridor prior to construction and installation activities.
