Prysmian Group has now been awarded a contract worth approximately €200 million ($223.9 million) by Vineyard Wind to provide the submarine power cable system which will deliver the energy to the power grid.
With the notice to proceed expected at the end of 2019, Prysmian Group will be responsible for the design, manufacture, installation and commissioning of an HVAC (High Voltage Alternating Current) cable system composed of two 220 kV three-core cables utilizing extruded XLPE insulation. The project requires a total of 134 km of power cables. The submarine cables will be produced in Prysmian Group’s production facilities in Pikkala, Finland, and Arco Felice, Italy. Installation operations will be performed by the company’s cable laying vessels Cable Enterprise and Ulisse. Delivery and commissioning of the project are scheduled for 2021.
Prysmian will also provide PRY-CAM permanent monitoring solutions consisting of long range Distributed Temperature Sensing (DTS) and state-of-the-art Real Time Thermal Rating (RTTR) systems collecting and analyzing data by ways of an artificial intelligence interface, which generates automated alarm signals if a critical situation is identified.
“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,” stated Hakan Ozmen, EVP Projects, Prysmian Group.
“The US 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 in the US market,” concluded Ozmen.
Vineyard Wind, owned 50 percent by Avengrid Renewables and 50 percent by funds from Copenhagen Infrastructure Partners, is the nation's first utility-scale offshore wind energy project. It is located over 14 miles off the coast of Massachusetts. It is scheduled to begin on-shore construction in 2019 and become operational by 2021.
