BTS 2023-11 Lecture: Hinkley Point C – Marine Works: Connecting Tunnels Under the Bristol Channel

Speakers:
Christoph Huber – Agent Steel Structures : Tunnel Shaft Connection, Balfour Beatty
James Long – Principal Engineer : Temporary Works Coordinator, Balfour Beatty

Internal-Ring-Propping (IRP) is nothing out of the ordinary and used on many projects to support the main tunnel while excavating a cross-passage. However, Balfour Beatty’s IRP system for Hinkley Point C Offshore Connections, which sits just 20,000 mm under the Bristol Channel, is one of a kind.
In their presentation, James Long and Christoph Huber will give an overview of the Tunnel-Shaft Connections and share their journey through the requirements for the design, manufacturing, and installation phase of this unique propping-system at Hinkley Point C.
