Nexans’ factory in Charleston, US, will supply the three 65km offshore export cables, and the company’s Aurora cable-laying vessel will install them. The vessel is currently under construction with delivery expected in the second quarter of next year.

Meanwhile, its plant in Charleroi, Belgium will manufacture the three 20km onshore export cables.

Seagreen project director John Hill said: “We are pleased to have Nexans’ expertise on the Seagreen project, as Nexans is a world leader in the supply and installation of subsea power cables.”

Nexans Subsea and Land System Business Group executive vice-president Ragnhild Katteland said: “We are delighted to receive this contract from SSE Renewables and we are excited to help bring the biggest windfarm in Scotland to life.”
