The 6 Offshore Liners at Hinkley Point C Successfully Installed by Balfour Beatty – Video

The international infrastructure group Balfour Beatty has announced today the successful installation of the six offshore liners at Hinkley Point C. This major milestone represents a crucial step forward as Hinkley Point C’s offshore works near completion.

Installed up to two miles off the coast in the Bristol Channel, with the second largest tidal range in the world, the six liners, each weighing up to 270t, will play a significant role in the power station’s vital cooling water system.

Lowered through 40m steel casings placed in the seabed earlier in the year, the six vertical liners will circulate 120,000 litres of water per second from the Bristol Channel to the nuclear power station through 5 miles of underground tunnels to provide cooling to the power station’s systems.

Reaching depths of 25m below sea level, each liner was designed with a world first, innovative pre-installed isolation cap, allowing safe, ongoing access to the cooling water tunnels for the remaining construction works prior to being fully removed and stored for use, should tunnel maintenance works be required.

Balfour Beatty’s Hinkley Point C Marine Works Project Director, Roger Frost, said: “This achievement is a significant step forward in our mission to contribute to the success of Hinkley Point C, a project that stands as a beacon for sustainable energy and engineering excellence.

“I am immensely proud of the progress we have made, and the depth and scale of this installment demonstrates Balfour Beatty’s capability to deliver innovative solutions for critical infrastructure.”

The installation marks the near completion in the offshore works at Hinkley Point C, with over 1,000 experts from across Balfour Beatty and its supply chain involved in its success. The final elements of the offshore works are expected to complete in the first half of 2024.
