Subject to Ørsted taking a Final Investment Decision on Hornsea 3, the contracts have been finalised with Haizea Wind Group, through its subsidiary Haizea Bilbao, and SeAH Wind Limited, a UK-based subsidiary of SeAH Steel Holdings (SeAH).
Ørsted will be the first major customer at SeAH Wind's new monopile facility in Teesside, and the agreement with Haizea marks the company's first XXL monopile contract with Ørsted.
The deal with SeAH represents the single largest offshore wind foundations contract secured by any UK company. Haizea's agreement is the largest single contract ever secured by Haizea Wind Group.
Each of the huge foundation structures for Hornsea 3 will weigh between 1,300 and 2,400 tonnes and measure in at between 83 and 111 metres in length. Monopile production is expected to start in 2024.
With a capacity of 2,852 MW, Hornsea 3 will produce enough low-cost, clean, renewable electricity to power around 3.2 million UK homes, making a significant contribution to the UK Government's ambition of having 50 GW offshore wind in operation by 2030 as part of the British Energy Security Strategy.
Hornsea 3 will be located 160 km from the Yorkshire coast. When it is fully online, Ørsted's Hornsea zone - comprising Hornsea 1, 2 and 3 - will have a total capacity of in excess of 5 GW. This will be the world's largest offshore wind zone, producing enough low-cost, clean, renewable electricity to power more than 5 million UK homes.
Hornsea 3 Senior Project Director, Luke Bridgman, said: "Hornsea 3 represents another leap forward in terms of the size and scale of offshore wind farms. As well as adding a significant source of low-cost clean energy, the project is also supporting the further development of the UK supply chain. Through our projects, we are also making ongoing efforts to work with new and expanding players coming into the market to support reducing the cost of energy."
Ørsted is proud to have been constructing and operating offshore wind projects in the UK for over 15 years. In the past five years alone, the company has directly placed major contracts with over 200 UK companies, with many hundreds more supported indirectly to help build and maintain our offshore wind farms.
