Under the contract awarded in 2019 by Vineyard Wind, LLC, a US offshore wind development owned by funds of Copenhagen Infrastructure Partners and by Avangrid Renewables, Prysmian Group will develop a submarine power cable system project which will deliver the energy to the mainland power grid.

Prysmian is responsible for the design, manufacture, installation, and commissioning of a High Voltage Alternating Current (HVAC) cable system composed of two 220 kV three-core cables utilising extruded XLPE insulation.

The project requires a total of 134 kilometers of power cables. The submarine cables will be produced in Prysmian Group’s centres of excellence for the production of submarine cables in Pikkala, Finland, and Arco Felice, Italy.

Installation operations will be performed by Prysmian Group’s cable laying vessels Cable Enterprise and Ulisse. The delivery and the commissioning of the project are scheduled for the fourth quarter of 2023.

Prysmian will also provide PRY-CAM permanent monitoring solutions, the Group’s technology that allows on-line, accurate and reliable in-depth information helping electric assets owners to increase uptime, asset longevity and safety, while reducing maintenance costs and risks, the company said.

“The resumption of the Vineyard project confirms the acceleration of the United States towards the energy transition,” said Hakan Ozmen, EVP Projects, Prysmian Group.

”Prysmian aims at playing a key role in the development and upgrade of power grid infrastructures to support the transition to renewable energy sources in the US. We have state-of-the-art cable technology, large production and installation assets, as well as a wide presence and track record in the US.”
