The Prysmian Group has won a contract worth approximately €200 million from Vineyard Wind, LLC, that will require a total of 134 km of power cables for a project that was described as the first U.S. utility-scale offshore wind energy project.
A press release said that Prysmian Group will be responsible for the design, manufacture, installation and commissioning of an HVAC (High Voltage Alternating Current) cable system for the project, which is located 14 miles off the coast of Massachusetts. The two, 220 kV three-core cables, which will use extruded XLPE insulation, will be produced at the Prysmian Group’s plants in Pikkala, Finland, and Arco Felice, Italy. Installation operations will be performed by two Prysmian Group cable-laying vessels: the Cable Enterprise and Ulisse. Delivery and commissioning are scheduled for 2021.
The release said that Prysmian will also provide PRY-CAM permanent monitoring solutions that include long-range Distributed Temperature Sensing (DTS) and Real Time Thermal Rating (RTTR) systems that collect and analyze data by ways of an artificial intelligence interface, which generates automated alarm signals if a critical situation is identified. “PRY-CAM is the Group’s breakthrough technology that allows on-line, accurate and reliable in-depth information to helps electric assets owners to increase uptime, asset longevity and safety, while reducing maintenance costs and risks.”
“This contract reinforces Prysmian Group’s leading position in the submarine cable market and underpins both our continued role and our commitment to the North American offshore wind sector,” the release said. Hakan Ozmen, EVP Projects, Prysmian Group, observed that the U.S. offshore wind market “is now demonstrating a high level of motivation with a promising growth forecast and we are excited to contribute to realizing this opportunity.”
The project will provide power for some 400,000 homes and businesses while reducing carbon emissions by over 1.6 million tons per year, the release said. To date, there has been just one off-shore wind farm, that the small (30 MW) Block Island Wind Farm off the coast of Rhode Island that began operation in 2016. More projects are now underway or planned, with the state of New York alone seeking to achieve 2,400 MW of offshore wind capacity by 2030.
An offshore wind development company, Vineyard Wind, LLC, is 50% owned by funds of Copenhagen Infrastructure Partners and 50% by Avangrid Renewables (part of the Iberdrola Group).
