SSE and TotalEnergies have selected Seaway 7 as the preferred contractor to build the 500MW Seagreen 1a offshore wind project off Scotland.
The project is expected to commence in 2023 with offshore work commencing in late 2024 and could be operational by 2025/26.
Seaway 7’s scope of work is under final negotiation and may include the full engineering, fabrication, transport and installation of 36 foundations, transportation and installation of the offshore substation and the procurement and installation of array cables.
Execution of the scope will be led from Seaway 7’s Aberdeen office.
The timeframe and Seaway 7’s selection are subject to the Seagreen 1a project securing consent and a final investment decision by SSE Renewables and TotalEnergies.
The value related to this “very large” agreement is expected to be recognised in Seaway 7’s backlog after final contractual terms have been agreed.
Seaway is already lead foundations contractor on the 1.1GW Seagreen 1, which is currently in construction.
Stuart Fitzgerald, CEO of Seaway 7, said: “We are delighted to be continuing our successful relationship with SSE Renewables and TotalEnergies to progress the Seagreen 1a project.
“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.”
John Evans, CEO of parent company Subsea 7, added: “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.”
