Ørsted to use Teesworks for Hornsea 3 marshalling

Posted on 23 July 2025

Ørsted has signed a deal to use up to 3.2 million sq feet (300,000 sq m) at the Steel River Quay – a key part of the Teesworks site – for its Hornsea 3 offshore wind farm.

The Danish company will use the site to collect and store key components for the project, such as monopile foundations and secondary steel, before they are loaded onto offshore wind installation vessels.

Senior project director Hornsea 3 Jason Ledden said: “Ørsted’s choice of Steel River Quay at Teesworks for Hornsea 3 demonstrates our continued commitment to investing in British infrastructure, growth and jobs. The port is the first in the UK to be specifically designed for the offshore wind industry and we’re proud to be its first large-scale users.

“Offshore wind is not only generating clean, plentiful energy – it’s bringing economic benefits to communities all around the UK.”

Steel River Quay is based on the south bank of the River Tees in the Teesside region, one of the UK’s major industrial regions and a site of multiple clean energy developments.

The site includes two of Hornsea 3’s contract partners – Severfield, which will supply secondary steel structures, and SeAH, one of the wind farm’s monopile suppliers.

SeAH is looking to finish construction of its monopile facility soon, with the first foundations expected to enter production later this year.

In addition, Cadeler will supply the vessels to Hornsea 3 from Steel River Quay, with Mammoet carrying out heavy lifting operations.

Steel River Quay managing director Ally Cameron said: “This is a landmark moment for Steel River Quay and the wider Teesworks site. To welcome Ørsted’s Hornsea 3 project as our first large-scale offshore wind base is a huge vote of confidence in the infrastructure, location and capability we’ve built here.

“This partnership will not only deliver clean energy infrastructure for the UK but also drive jobs, investment and opportunity for our region.”

The 4,500-acre Teesworks site is based around the former Redcar steelworks, which closed in 2015 leading to the loss of 2,000 jobs.

Now, the area is being developed to provide a centre for green industry, including the UK’s largest freeport.

Energy minister Michael Shanks said: “Our mission to become a clean energy superpower is focused on attracting investment for local communities, creating new jobs, and ensuring energy security for families and businesses.

“This partnership delivers on that promise – Hornsea 3 will drive growth throughout Teesside and help rebuild Britain’s industrial heartlands as part of our Plan for Change.”
