Bladt Industries and Semco Maritime have secured a contract for the fabrication and delivery of the
Mayflower offshore wind project’s offshore substation, which is to be installed 40 kilometres south of Nantucket, Massachusetts.

The contract was awarded by project developers Mayflower Wind Energy LLC, a joint venture between Shell New Energies US LLC and EDPR Offshore North America LLC).  The offshore substation is scheduled for delivery from Bladt Industries’ site in Denmark in 2024.


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.


We are proud that Mayflower Wind has selected Bladt and Semco for this comprehensive offshore substation project on the US East Coast. We consider it an important recognition of our joint competencies and our strong focus on HSE during the construction phase,” said Nils Overgaard, Chief Sales Officer, Bladt Industries. “We are very much looking forward to the close cooperation with the strong team behind Mayflower Wind, and we do hope this will be the first of several projects.”


“Semco and Bladt’s strong track record of providing competitive turnkey offshore wind electrical infrastructure is a door opener in the market. The Mayflower Wind project provides a unique opportunity to firmly establish our companies as highly experienced pioneers in the nascent and promising US offshore wind industry. We will build strong relationships with Mayflower Wind’s parent companies – Shell and EDP Renewables – as well as other involved parties. We will draw on the experience gained, as well as the resources and capabilities, that we have built up over the years to put further focus on our offerings to bring offshore energy to shore,”
said Carsten Nielsen, Senior Vice President, Renewables, Semco Maritime.


Mayflower Wind LLC anticipates that the project will commission in 2025. It was named winner of the Commonwealth of Massachusetts’ second offshore wind solicitation in November 2019. The joint venture was successful with a bid of 804 MW which is expected to power approximately half a million homes and eliminate 1.7 metric tons of CO2 emissions annually.
