UK-based Enshore Subsea has won an export cable installation deal on Scotland’s Inch Cape offshore wind farm.
Inch Cape will have two 85-kilometre, 220kV, 3-phase export cables which, based on their diameter and weight, are amongst the largest export cables in the world. Each cable will be delivered in three sections requiring offshore field joints.
During the project, Enshore Subsea will be responsible for the export cable installation including transfer from port to site, lay and burial, and support during jointing and deployment of the cable protection system.
Enshore Subsea will also be responsible for all pull-in operations and installation of the export cables, into both the transition joint bay at Cockenzie, East Lothian, and the offshore substation located off the Angus coastline.
The project will see Enshore Subsea begin offshore work in the summer of 2025. Cable laying will be carried out using the CMOS Installer cable lay vessel. The cable will be buried using assets from Enshore Subsea’s fleet of subsea trenchers.
At almost 1.1GW, Inch Cape is in water depths ranging from 40 to 59 m and will be made up of 72 wind turbine generators, each standing up to 274 metres tall. Inch Cape Offshore Limited, a joint venture between ESB and Red Rock Renewables, is the developer of the project.
