SeAH Wind has signed its largest ever contract - securing well over 700 jobs at its Teesworks site.

The contract with Vattenfall to supply all the wind turbine monopiles for its Norfolk Vanguard Project, positions SeAH Wind as the UK’s leading Foundation Manufacturer and ensures that the UK is at the forefront of developing offshore wind globally.

The agreement to supply all the XXL Monopiles from SeAH Wind’s new factory currently under construction at the former steelworks site, is not only the largest order for foundations for a UK based manufacturer but is also the largest single contract secured in the history of SeAH.

SeAH says it can now plan and grow the business with order security from 2025 until the end of 2027. Production is due to start in 2026, and continue until the end of 2027, utilising the Teesworks heavy duty quay for both incoming raw materials, and outbound monopiles, which will range from 10-11 meters in diameter, weighing between 1,600 and 2,250 tons each, and varying in length from 70 – 95 meters. 

Minister for Investment Lord Johnson said: “I’m delighted that SeAH Wind has increased its investment to £650 million to build a state-of-the-art manufacturing facility in Teesside.

“One of the largest facilities of its kind in the world, this fantastic investment is set to create up to 750 jobs by 2030 and is a great success for the UK’s energy security commitments. This is a major vote of confidence in our offshore wind expertise from Vattenfall and will create significant jobs and drive growth in our supply chains.

SeAH CEO Chris Sunghwal Sohn, said: “We thank Vattenfall for their trust in SeAH Wind, the UK market has needed an injection of good news, and this contract is a clear signal that UK based companies can be a success in the Offshore Wind industry. Now we focus on the future, completing our factory, recruiting the best talent, and making SeAH Wind the market leader in producing the largest monopiles.”

Catrin Jung, Head of Offshore Wind at Vattenfall, said: “We are delighted to be working with SeAH Wind. These projects are vital for net zero and providing customers with a low carbon energy system.”

Tees Valley Mayor Ben Houchen said: “This contract announcement is outstanding news for Teesside and a huge vote of confidence in our area’s ambition to be the UK capital for offshore wind manufacturing.

“This will secure 750 high-quality, well-paid jobs for local workers and clearly demonstrates the transformation taking place on Teesworks in becoming the home for the green, clean industries of the future.

“It also shows how the successful redevelopment of the site and vital investment in projects such South Bank Quay have been essential in laying the groundwork for us to reap the rewards from major contract decisions such as this.”

Teesworks Chairman Chris Musgrave said: “This deal is more great news for Teesworks and secures more good quality jobs for Teessiders.

“We’ve been busy putting the building blocks in place for companies like SeAH, our heavy lift quay is all but built as is the South Bank link road ready to support this vast site.

“Next year will be another big year for Teesworks, where we start to see more construction and businesses moving into the operational phase. It’s an exciting time and I’m proud of the difference this site is already making on the local communities.”
