Seaway7 Completes Seagreen Jacket Campaign

Seaway7 has installed the final wind turbine foundation on Seagreen Offshore Wind Farm, off the coast of Angus, concluding the 18-month installation campaign. The 114th jacket foundation was successfully installed late afternoon on Thursday by the Saipem 7000 crane vessel, which was used to lift each of the 2,000t foundations into place.

As the main contractor, Seaway7 has managed the engineering, procurement, construction, and installation of the wind turbine generator foundations and is installing approximately 300km of associated inner-array cables.

Seagreen topped its own record from October 2022 by installing foundation number 112 at a depth of 58.6m.

This major milestone followed soon after the installation of the world’s deepest wind turbine foundation which was achieved on Easter Sunday. Seagreen topped its own record from October 2022 by installing foundation number 112 at a depth of 58.6m.

Seagreen’s Project Director, John Hill, said, “Installing all 114 jackets is one of the most significant milestones in the project. The Seagreen team have now installed more suction caisson foundations than any other offshore wind farm and pushed forward the boundaries of this technology. The Seagreen team and Seaway7 have excelled in the delivery of this complex scope of work which has resulted from outstanding effort on the installation phase by teams including those at Ramboll, Saipem and Global Energy Nigg. A huge thanks on behalf of SSE and Totalenergies shareholders for this achievement.”

Lloyd Duthie, Vice President UK, Ireland and Asia at Seaway7 said, ‘We are immensely proud to be playing a significant role in the construction of the momentous Seagreen offshore wind farm. This achievement is the culmination of more than three years of hard work since the contract award to Seaway7 in June 2020, and sets a new benchmark for jacket fabrication and transportation of this scale in the offshore wind industry.’

David Mitchell, Seagreen Project Director at Seaway7 said, “This is a significant milestone for Seagreen and Seaway7. Good collaboration between all parties has been instrumental in the safe and timely execution of this complex and challenging project. We look forward to the completion of the cable installation in the coming months to conclude our full EPCI scope”. Each foundation will support a Vestas V164-10MW turbine.

When complete, the 1.1GW wind farm will be capable of generating around 5,000GWh of renewable energy annually which is enough clean, secure, sustainable electricity to power more than 1.6m UK homes.
