Cape Wind ropes cable guys
Prysmian to supply lines, Caldwell Marine to tackle subsea installation
South Carolina-based Prysmian Cables and Systems USA has won a contract to supply inter-array and export power cables for the 468MW Cape Wind offshore wind farm.
New Jersey-based Caldwell Marine International has also been roped for installation of the underwater cables at the scheme off the coast of Massachusetts, which will feature 130 Siemens 3.6MW turbines. The two deals were revealed exclusively in subscription-only newsletter reNews last year.
"I am pleased that Prysmian Cables and Systems USA and Caldwell Marine International will play important roles in helping build Cape Wind, they are capable companies that will help establish a domestic offshore wind supply chain," said Cape Wind president Jim Gordon.
The onshore transmission cables will be manufactured by Prysmian at its high voltage manufacturing facility in Abbeville, South Carolina. They will be installed by its New Jersey-based team in a series of duct banks between the point of landfall and the electric grid interconnection at the NSTAR Barnstable substation.
The duct banks will be constructed by Falmouth-based Lawrence-Lynch Corp under an agreement Cape Wind revealed previously.
Caldwell Marine International will install the submarine inter-array and export cables “using specialised vessels and equipment”, Cape Wind said.
Caldwell Marine International president Rolando Acosta added: "We are thrilled to be expanding into the offshore wind sector and we are proud to help build Cape Wind, America's first offshore wind farm. This is an opportunity for our company to become part of the supply chain of this new domestic offshore wind industry.”
