Construction Other

Ørsted and SeAH Wind announced on 17 February 2026 that they had mutually agreed to discontinue SeAH Wind's monopile production scope for the Hornsea 3 offshore wind farm, terminating the 2022 fabrication contract under which SeAH Wind was to manufacture XXL monopiles at its Teesworks facility on Teesside. The joint statement said the decision "reflects a shared assessment of factory readiness against the programme requirements of Hornsea 3" and was made to ensure the project schedule "remains protected and uncompromised" — a reference to delays in the SeAH Wind plant's commissioning. The SeAH Wind facility, originally a £450 million development that was rescaled in 2024 to a £900 million build covering a 90 ha site capable of producing monopiles up to 15.5 m diameter, will continue under construction with secured backlog including RWE's Norfolk Vanguard. Ørsted's Hornsea 3 monopile supply remains anchored on Haizea Wind Group (Bilbao, Spain), which delivered its first six XXL monopiles to Teesside in February 2026, and Dajin Heavy Industry (China), which began heavy-cargo deliveries via its King One deck carrier in March 2026. Ørsted continues to use Teesworks's deepwater quay as the marshalling base for monopile assembly and load-out to installation vessels. The cancellation is a notable supply-chain reset on the world's largest single offshore wind farm but, per Ørsted's framing, does not affect the project schedule.
