US East Coast Inter Array Cable Contract for DEME Offshore US

 Representing a substantial contract, DEME Offshore US will be responsible for the transport and installation of the inter-array cables, which have a total length of over 350 km (217 miles). Empire Wind 1 and 2, located on the East Coast of the US, will be a major contributor to meeting New York State’s ambitious clean energy and climate goals.

The installation works will be performed by a cable installation vessel from the DEME fleet in two campaigns. Currently the company operates the state-of-the-art cable installation vessel ‘Living Stone’ and this will be joined by a second DP3 cable installation vessel ‘Viking Neptun’ in Q1 2023.  This addition to the fleet confirms DEME’s cable installation capabilities and its leading position in the market.  

‘Viking Neptun’ was set to join the DEME fleet in the last quarter of 2022 following its purchase agreement with Eidesvik in January 2022

Sid Florey, President DEME Offshore US, comments: “We are very proud Equinor has awarded DEME Offshore US these two exceptional projects. DEME’s excellent track record and ability to successfully execute large-scale cable projects safely and efficiently, combined with our robust technical solution for the Empire Wind projects, are the key factors for our success with the award of this contract.”

Additionally, this contract highlights the continued expansion of our US portfolio through our office in Boston and our commitment to the future growth of the US offshore wind market, he emphasises.

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