Semco and Bladt Joint Venture to Provide Mayflower Wind Offshore Substation

The scope comprises engineering, procurement and construction works, including steel structure and jacket foundation by Bladt, as well as design, procurement and installation of electrical equipment, auxiliary systems and inter-array cables by Semco Maritime.

According to Semco, the 1,200MW offshore substation will consist of a 4,700t topside and a 3,000t jacket foundation.

The project will be initiated this month, while the substation is scheduled for delivery from Bladt’s site in Denmark in 2024.

“Recent changes to U.S. tax law now allow projects that meet qualification standards in 2020 to secure Federal Investment Tax Credits at the 18% level. This contract is a key step for us to meet these standards and secure tax credits that would ultimately result in a lower rate for electricity customers in Massachusetts,” said Michael Brown, Chief Financial Officer, Mayflower Wind Energy LLC.

Mayflower Wind Energy LLC, a joint venture of Shell New Energies US and EDPR Offshore North America, was chosen in 2019 to develop its 804MW offshore wind project.

The offshore wind farm is expected to be commissioned in 2025 at the site more than 20 miles south of Nantucket.
