SeAH Wind Monopile Facility
Powering the Future of Offshore Wind
The SeAH Wind monopile factory at Teesworks is a landmark achievement in renewable energy infrastructure. Standing 40 metres tall and stretching 800 metres in length, it is the largest facility of its kind in the world—supporting the UK’s drive to decarbonise electricity and accelerate the growth of the offshore wind sector.
SES appointment and scope
Appointed by K2 Construction Management on behalf of SeAH Wind, SES Engineering Services delivered the full mechanical and electrical works for the main facility. The project was delivered in collaboration with a local supply chain and workforce, exemplifying SES’s commitment to partnership and regional impact.
Strategic importance
As the first major development on the Teesworks site—one of Europe’s largest regeneration programmes—the facility was designed to produce 100–150 monopiles annually. These large steel tubes form the foundations for offshore wind turbines and are transported directly to Teesworks’ South Bank Quay for deployment to the North Sea.
Scale and capability
The completed development provides 1.13 million sq ft of high-quality factory space, capable of producing monopiles up to 120 metres in length, 15.5 metres in diameter, and weighing up to 3,000 tonnes. This facility plays a pivotal role in supporting the UK’s commitment to quadrupling offshore wind capacity.
Technical highlights
- Strategic Energy Infrastructure: A key component of the UK’s renewable energy strategy, enabling large-scale offshore wind deployment.
- Collaborative Delivery Model: SES worked closely with K2 and regional partners, leveraging local expertise and supply chains.
- Advanced Electrical Systems: High-level lighting installation and complex module busbar systems to support manufacturing operations.
- Sustainable Construction Impact: Part of Europe’s largest regeneration site, driving economic growth, job creation, and environmental benefits.
“We pride ourselves on working with the local supply chain, so we’re delighted to be working with SES on this mammoth build for SeAH Wind. SES is a leader in its field and their professionalism and expertise will be of paramount importance to supporting our successful delivery of this project.”
