DEME to Deliver Empire Wind Inter-Array Cables

DEME Offshore US has been awarded a contract by Empire Offshore Wind, a joint venture between Equinor and bp, to supply inter-array cables for the Empire Wind 1 and Empire Wind 2 offshore wind farms.

DEME Group

Under the contract, DEME Offshore US will be responsible for transporting and installing inter-array cables, which will have a total length of over 350 kilometres. The contract is valued between EUR 150 million and EUR 300 million.

The installation works will be performed by a cable installation vessel from the DEME fleet in two campaigns.

Currently, the company operates the installation vessel Living Stone and this will be joined by a second DP3 installation vessel Viking Neptun in the third quarter of 2023.

Empire Wind 1 and Empire Wind 2 offshore wind farms are proposed to be built in waters between 24 and 48 kilometres offshore Long Island.

The 816 MW Empire Wind Phase 1 wind farm was selected in New York’s first-ever offshore wind solicitation in 2019 alongside Ørsted and Eversource Energy’s Sunrise Wind project.

The 1,260 MW Empire Wind 2 was selected in the state’s offshore wind power solicitation in January 2021 together with their Beacon Wind 1 project south of Nantucket.

The offshore wind farms will utilise 15 MW wind turbines and are expected to play a major role in meeting New York State’s goal of reaching 70 per cent renewable energy by 2030, according to the developers.

Once completed, Empire Wind 1 and Empire Wind 2 will have a total installed capacity of more than 2 GW and will power more than one million New York homes.
