”We are immensely proud to be a part of Vineyard Wind 1, which will always carry a special status being the first commercial scale offshore wind farm in the US. Many years ago, we were a part of the first offshore wind projects in Denmark when the industry evolved here, and it feels great adding a new chapter to our story with our involvement in the first US project,” said Klaus Munck Rasmussen, Chief Project Officer, Bladt Industries.

Vineyard Wind 1 is carried out as an EPC contract, with ISC as a subcontractor, covering the design, procurement, and construction of the 3,200-ton offshore substation and a 2,000-ton jacket foundation with four piles, which form the permanent anchorage to the seabed.

Bladt has handled the steel manufacturing of the substation. Design and engineering were carried out by Semco Maritime and ISC, and installation of the electrical system was also carried out by Semco Maritime.

”We have had a very constructive collaboration with the client, Vineyard Wind LLC, and it has been a rewarding process to draw on our many years of experience and well-tested setup for the execution of this project, resulting in a safe handover to the client,” said Steen Brødbæk, CEO, Semco Maritime.
