Danish engineering services company ISC 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 and Semco Maritime selected ISC, after they secured the engineering, procurement and construction (EPC) contract for the substation in January.
As a subcontractor to Bladt Industries, ISC will perform the engineering design works together with Semco Maritime. US partner WSP will provide US offshore wind permitting and engineering “expertise” to the team.
The offshore substation will consist of a topside weighing 4400 tonnes and a jacket foundation weighing 3000 tonnes.
The EPC scope is to be delivered by Bladt Industries and Semco Maritime.
The scope 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, being developed by Shell and EDPR, has been chosen by the Commonwealth of Massachusetts to supply 804MW of clean, renewable energy from offshore wind with expected start-up in 2025.
