Pelagian has been providing cable route engineering support to numerous offshore wind farms in the Irish Sea since 2009, including Walney, Ormonde, West of Duddon Sands and Gwynt Y Mor.

Project work has included the design and layout of export and array cables, landing point optimisation, selection of burial equipment and burial assessment, managing cable crossings over existing seabed infrastructure and geospatial data management.

The seabed in this region provides a number of challenges for cable installation and burial, where mobile sediments, glacial till and boulders are commonplace. The cable route layouts and selection of burial equipment were designed to take into consideration the prevalence of these hard ground conditions and mobile sediments.
