Danish engineering services company ISC Consulting Engineers has been awarded a contract to design the offshore substation for the 804MW Mayflower offshore wind farm 40km off the coast of Massachusetts.
Bladt Industries, a steel contractor specializing in offshore substations and offshore foundations, and the project engineering company Semco Maritime selected ISC, after they secured the engineering, procurement and construction (EPC) contract for the substation in January.
The offshore substation (ESP) EPC project was initiated in January 2020, and as sub-contractor to Bladt Industries, ISC will perform the engineering design works together with Semco Maritime and the US partner WSP adding WSP’s expertise in U.S. offshore wind permitting and engineering to the team.
"Applying ISC experience from the engineering design of more than 36 offshore wind farm substations and the Mayflower Wind ESP being the second ISC offshore substation design to be realized in US waters, ISC looks forward to working with our long term partners Bladt Industries, Semco Maritime and WSP to realize this important project with the strong Mayflower Wind Team," said a press release.
The offshore substation will consist of a topside of 4,400 tons and 3,000 tons 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 804 MW of clean, renewable energy from offshore wind with 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.
