Cape Wind has contracted Weeks/Manson, a joint venture (WMJV) of Weeks Marine and Manson Construction, for the installation of 130 wind turbines at its proposed Nantucket Sound offshore wind farm, claimed to be the first of its kind in the US.
Workers for the project will be supplied by The Boston & New England Maritime Trades Council, AFL-CIO, and WMJV will serve as lead construction contractor.
The appointment of WMJV replaces the Cape Wind’s joint venture of Flatiron Construction, Cal Dive International and Cashman Equipment, which were selected by the company in 2012 for building turbines.
For the wind turbine installation, WMJV will use a fleet of vessels including a jack up barge, RD MacDonald, which is the first US-built offshore wind installation vessel built by Weeks Marine.
The 260ft vessel is installed with a crane and a 280ft boom that allows it to reach over 350ft in the air when jacked up offshore.
The jack up barge has the capacity to transport three wind turbines at once and has enough space to carry the turbine blades.
WMJV project director and Weeks Marine vice-president Rick Palmer said: "We are excited to build Cape Wind and help launch the US offshore wind industry.
"We have been pursuing this new market for over ten years and we admire the perseverance of the Cape Wind team."
AFL-CIO president Gerard Dhooge said: "This announcement is another big step forward for Cape Wind and our members are looking forward to getting to work on constructing this important project."
WMJV has appointed Massachusetts-based Fall River Electrical Associates as its subcontractor for performing electric outfitting work for the project.
Cape Wind president Jim Gordon said: "This project will combine the best of American maritime suppliers, engineers and constructors with the most experienced European technology providers to ensure America’s first offshore wind farm performs to world-class standards.
"Achieving this objective will help catalyse a new industry that will deliver an inexhaustible clean energy resource and thousands of new jobs for our region and country."
