The survey, conducted using uncrewed survey vessels (USVs), took place over a span of 13 months, in water depths ranging from the shoreline to over 100 meters.
The gathered data will support Ossian’s engineering and development teams and Environmental Impact Assessment (EIA) consultants in identifying viable routes for the offshore export cables, XOCEAN said.
According to Kevin Harnett, CRO of XOCEAN, the survey was conducted in multiple phases, with up to six USVs operating in the North Sea.
During the campaign, the project team coordinated with the National Grid Electricity Transmission (NGET) to align their efforts and minimize interference, said the Irish company.
“The completion of the XOCEAN survey is a huge milestone in progressing towards selection of the most feasible route for our offshore export cables. The campaign has delivered information vital to understanding seabed characteristics, habitats, and the geology of the offshore export cable route, setting out our path for the future,” said Laurent Domergue, Ossian Engineering Manager.
