350

Dominion Energy has selected some offshore wind supplying partners to support Coastal Virginia Offshore Wind, the largest offshore wind farm under development in the U.S.
The selections include:

  • DEME Offshore/Prysmian Group for transportation and installation of balance of plant, subsea cable supply and installation.
  • Bladt Industries to supply transition pieces.
  • Bladt and Semco to supply three offshore substations.
  • EEW SPC to supply steel monopile foundations.

In 2020, Dominion announced wind-turbine manufacturer Siemens Gamesa Renewable Energy as the preferred turbine supplier for the 176 14.7-MW turbines to be installed in the 112,800-acre commercial lease area.

“We are moving the CVOW project forward by working with industry leaders as we bring utility scale offshore wind generation to our Virginia customers,” said Joshua Bennett, Dominion Energy vice president of offshore wind. “These contracts will allow us to manage costs for the benefit of our customers and take advantage of the developing domestic supply chain to deliver on our promise to bring clean-energy jobs to Hampton Roads.”

EEW SPC, with more than 80 years of experience in production of steel pipe and corresponding pipe components, will manufacture 176 steel monopile foundations, the largest of which will be 268 feet long and weigh 1,755 tons.

“With the construction of Coastal Virginia Offshore Wind, Dominion Energy is getting closer to its goal of being carbon neutral, in terms of power generation, by 2050, and we are pleased that we can also do our part,” said Heiko Mützelburg, CEO/Managing Director of EEW SPC.

Bladt Industries will manufacture 176 transition pieces, which weigh as much as 800 tons and bind the monopile foundation and turbine together, while providing physical access to the turbines.

“We are proud to be selected by Dominion Energy for this contract based on our experience and proven track record. Likewise, we are extremely proud to be part of building up the growing American offshore wind industry,” said CEO Anders Søe-Jensen from Bladt Industries.

Bladt Industries and Semco Maritime will manufacture components for the three offshore substations, which are multi-story units weighing about 4,000 tons each, a topside platform with helicopter landing pad 157 feet above the water and support structures installed in the sea floor.

“We are proud of the contract for three 880 MW substations, which we consider a vote of confidence in Semco’s and Bladt’s tried and tested partnership and our strong track record of delivering competitive projects within electrical infrastructure for offshore wind through two decades,” says Steen Brødbæk, CEO, Semco Maritime.

DEME Offshore US LLC and Prysmian Group will provide the balance of plant services, including the transportation and installation of the foundation and substation components, and install the subsea cables.

Prysmian Group, a global leader in the energy and telecom cable systems industry will provide all of the subsea inter-array and export cables that will deliver the renewable offshore wind energy to shore.

Monopile foundations, transition pieces, and turbine components will be staged on 72 acres at Portsmouth Marine Terminal (PMT) as part of a 10-year lease agreement with the Virginia Port Authority. Doing so will employ union jobs such as longshoremen, stevedores, crane operators and other building and construction trade jobs, as well as skilled labor from the North America’s Building Trade Union and its state affiliate Virginia Building Trades.
