Semco Maritime and Bladt Industries to develop offshore substation for 804 MW Mayflower offshore wind project in Nantucket

Mayflower Wind Energy LLC (a joint venture of Shell New Energies US LLC and EDPR Offshore North America LLC) has awarded a contract for the fabrication and delivery of the Mayflower Wind project’s offshore substation approximately 40 kilometers south of Nantucket, Massachusetts, to a joint venture comprised of long-standing business partners Bladt Industries and Semco Maritime. The offshore substation project will be initiated in January 2020.

Bladt Industries and Semco Maritime have formed a joint venture for the design and construction of the 1,200 MW offshore substation. The offshore substation will consist of a topside of 4,700 tons and a 3,000 tons jacket foundation.

The project scope comprises engineering, procurement and construction works, including steel structure and jacket foundation by Bladt Industries, as well as design, procurement and installation of electrical equipment, auxiliary systems, and inter-array cables by Semco Maritime. The offshore substation is scheduled for delivery from Bladt Industries’ site in Denmark in 2024.

The Mayflower Wind project has been chosen by the Commonwealth of Massachusetts to supply 804 MW of clean, renewable energy from the offshore wind with an expected start-up in 2025. Once in operation, the project will provide enough electricity to power approximately half a million homes in the state and eliminate 1.7 metric tons of CO2 emissions annually.

Bladt Industries and Semco Maritime will act as equal partners in the new joint venture.
