SeAH Wind has secured a deal to supply all monopiles for Vattenfall’s 2800MW Norfolk Vanguard offshore wind farm in the UK North Sea.
Production on what is the fabricator’s largest single contract will start in 2026 from its under-construction facility in Teesside, north-east England.
Steel work will run to the end of 2027 under a deal that will secure over 750 new jobs, according to SeAH.
The XXL monopiles for Norfolk Vanguard West and Vanguard East will range from 10 to 11 metres in diameter, weighing between 1600 and 2250 tonnes each, and measuring from 70 to 95 meters in length.
With this order, SeAH said it can now plan and grow the business with order security from 2025 until the end of 2027, “providing the perfect launching pad to ensure continued success at the world’s largest single site XXL monopile factory”.
SeAH chief executive 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, added: “We are delighted to be working with SeAH Wind who will be providing the monopiles for Norfolk Vanguard East and West Wind Farms.
“These projects are vital for net zero and providing customers with a low carbon energy system.”
Energy Security Secretary Claire Coutinho said: “SeAH Wind’s investment of more than £600m in Teesside is a clear vote of confidence in the UK’s manufacturing industry and highlights the attraction of our world leading renewables sector.
“The North East is vital to our clean energy transition, and today’s deal with Vattenfall is further good news for local communities and businesses through the creation of more than 500 highly skilled jobs in the region.”
Minister for Investment Lord Johnson also heralded the deal.
“I’m delighted that SeAH Wind has increased its investment to £650m 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.”
