Seagreen 1 has selected Seaway 7, part of the Subsea 7 group, as the preferred supplier for the Seagreen 1A offshore wind project in Scotland, expanding its existing work on the adjacent Seagreen project.
Seaway 7’s work on the Seagreen 1A project could include full engineering, fabrication, transport and installation of 36 foundations, the transportation and installation of the offshore substation, and the procurement and installation of inner-array cables, although the scope is under final negotiation.
“We are delighted to be continuing our successful relationship with SSE Renewables and TotalEnergies to progress the Seagreen 1A project,” said Seaway 7 chief executive Stuart Fitzgerald.
“The project will continue to be managed from our office in Aberdeen where we are bringing over a decade of UK offshore wind expertise to Scotland’s largest offshore wind project.”
The Seagreen Offshore Wind Farm project in the North Sea is a joint venture between TotalEnergies and SSE Renewables and plans to install 150 turbines. The first 114 turbines are under construction and expect to be fully operational by 2023.
The additional 36 turbines will represent about 500 megawatts of renewable energy generation capacity and will connect to the grid through a new substation at Cockenzie, East Lothian. The other turbines use a substation at Tealing, near Dundee.
“We are very pleased to be continuing our proactive participation in the UK’s ongoing energy transition and we look forward to extending our long-term collaboration with SSE Renewables, which began in 2009 with the pioneering Greater Gabbard development and continued with Beatrice, Seagreen and Dogger Bank,” said Subsea 7 chief executive John Evans.
The Seagreen 1A project is expected to begin in 2023, with offshore work beginning in late 2024. The project could be operational by 2025 or 2026, Subsea 7 said, subject to the final investment decision.
