Fugro EMU was appointed by DONG Energy to carry out offshore pre-construction surveys for the Walney Extension offshore wind farm off Cumbria. Fugro’s work included geophysical surveying of the windfarm site and export cable route, using three specialist survey vessels (Fugro Helmert, RV Discovery, and Fugro Valkyrie). The survey programme was intended to provide detailed seabed information to support safe offshore construction, including collecting additional geophysical data and supporting UXO detection to help ensure the seabed was clear of obstructions such as unexploded Second World War ordnance before construction commenced.
