Virginia (3 x 880 MW)


A consortium of strategic partners Bladt Industries and Semco Maritime has been awarded a turnkey contract on the world’s largest offshore wind project so far – Coastal Virginia Offshore Wind– for U.S. utility company Dominion Energy Virginia.

The contract comprises three 880 MW offshore substations, which will be established in 2021-2025 and commissioned in 2026. The three substations will constitute the backbone of the electrical infrastructure for the 2.5 GW Coastal Virginia Offshore Wind project. The contract is Bladt Industries’ and Semco Maritime’s third offshore substation project in the U.S. and the two strategic partners’ 21st project together since their first cooperation in 2003.

The scope of work on the Coastal Virginia Offshore Wind project includes design, engineering, procurement, manufacturing and installation. Bladt Industries is responsible for design, procurement and manufacturing of steel structures and jacket foundations, while design, procurement and installation of electrical equipment, emergency systems and inter-array cables will be managed by Semco Maritime.
