French industrial cable supplier Nexans has been awarded a contract by SSE Renewables to deliver cables for the recently sanctioned 1,075 megawatt (MW) Seagreen offshore wind farm project.

The contract calls for Nexans to design, manufacture and install the high voltage (HV) onshore and offshore export cables.

Construction on the 1,075 megawatt (MW) project, which is located 27km off the coast of Angus, will start next year. When completed in 2022/23, Seagreen 1 will be Scotland's largest wind farm.

Nexans' factory in Charleston, South Carolina, will supply the three 65 km offshore export cables. This factory was recently expanded to manufacture HV subsea power cables and is currently the only facility with that capability in North America. The three 20 km onshore export cables for the project will be manufactured at Nexans' factory in Charleroi, Belgium.

The export cables for the Seagreen offshore wind farm project will be installed by the Aurora, Nexans' new cable-laying vessel (CLV). The Aurora is currently under construction and will be delivered in the second quarter of 2021.

The electricity generated by the Seagreen turbines will be transmitted via the subsea export cables to landfall at Carnoustie. Once ashore, the land cables will transmit the electricity to a new substation at Tealing where it will feed in to the UK's national electricity transmission system.

As reported earlier in June, French oil and gas major Total agreed to buy a 51% stake in SSE Renewables' Seagreen 1 offshore wind farm project, and with the deal the project also reached a final investment decision.

Following the FID, SSE started awarding construction and equipment contracts. Apart from Nexans, the contracts have so far been awarded to Subsea 7, Lamprell, MHI Vestas, and Petrofac.
