Major step for Vineyard offshore wind farm

5 October 2021

Notice to Proceed with the approximately €200 million contract to supply a submarine power cable system for the Vineyard Wind 1 offshore wind farm in the USA has been issued to the contractor Prysmian Group. The first large scale offshore wind farm in the USA, Vineyard will consist of an array of 62 wind turbines and generate 800 MWe.

The submarine cable contract was awarded in 2019 by Vineyard Wind, LLC, a US offshore wind development owned by Copenhagen Infrastructure Partners and Avangrid Renewables (part of the Iberdrola Group). Prysmian is responsible for the design, manufacture, installation and commissioning of an HVAC cable system consisting of two 220 kV three-core cables utilising extruded XLPE insulation. The project requires a total of 134 km of power cables, which will be produced in Prysmian’s centres of excellence for the production of submarine cables in Pikkala, Finland, and Arco Felice, Italy. Installation operations will be performed by Prysmian’s cable laying vessels Cable Enterprise and Ulisse. Delivery and commissioning of the project are scheduled for Q4 2023. 

Prysmian will also provide PRY-CAM permanent monitoring solutions, described by the company as a breakthrough technology that allows on-line, accurate and reliable in-depth information that helps asset owners to increase uptime, asset longevity, and safety, while reducing maintenance costs and risks.
