ISC and WSP Join Mayflower Wind Offshore Substation Roster

Danish engineering services company ISC Consulting Engineers has won a contract to design the offshore substation for the Mayflower Wind offshore wind project in the USA.

Back in January, Bladt Industries and Semco Maritime secured a contract to fabricate and deliver the offshore substation for the project located approximately 40 kilometers south of Nantucket, Massachusetts.

As a sub-contractor to Bladt Industries, ISC will perform the engineering design works together with Semco Maritime and the US partner WSP.

The offshore substation will consist of a topside of 4,400 tons and a 3,000-ton jacket foundation.

The EPC scope is to be delivered by Bladt Industries and Semco Maritime and comprises engineering by ISC and Semco, 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 804MW of offshore wind capacity with the expected start-up in 2025.

The project is being developed by Mayflower Wind Energy LLC, a joint venture of Shell New Energies US and EDPR Offshore North America.
