Prysmian Group has completed the installation and HV testing activities at the 800MW Vineyard Wind 1 off the coast of Massachusetts.
The project, a JV between Avangrid and Copenhagen Infrastructure Partners, consists of an array of 62 turbines.
The site was awarded to Prysmian Group in May 2019 and included the design, manufacture, installation and commissioning of an HVAC (High Voltage Alternating Current) cable system.
This is composed of two 220 kV three-core wires with extruded XLPE insulation that will deliver clean energy to the mainland power grid in the US and will help to reduce carbon emissions by more than 1.6m tonnes per year.
The 134km submarine power lines were manufactured at Prysmian Group’s centres of excellence in Pikkala, Finland, and Arco Felice, Italy.
Marine installation operations were performed by Prysmian Group’s Cable Enterprise and Ulisse cable laying vessels.
Executive vice president projects BU at Prysmian Group Hakan Ozmen said: “We are proud to have completed such an important and strategic project that confirms the United States’ acceleration towards the energy transition.
“Following the successful completion of the Viking Link cable operation, Prysmian further confirms its capability to smoothly execute important projects included in its portfolio.”
Head of project operations, projects BU at Prysmian Group Alberto Boffelli added: “With Vineyard Wind 1, we have demonstrated to the market our ability to bring ourexpertise, state-of-the-art cable technology and installation capabilities to the US market.
“Thanks to our investment in a new cable plant located at Brayton Point, Massachusetts, we are committed to reinforcing our footprint in the US, supporting the growing offshore wind market.”
