Overview

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.

Christoph Huber

Christoph's journey in the tunnelling business started over 12 years ago during an internship on Crossrail Easter Running Tunnels with Dr. Sauer. Ever since he found his passion underground and worked for BeMo Tunnelling on several tunnel projects in Austria, Germany, and the UK. Most recently he is (again) seconded to Balfour Beatty's HPC marine works team. Initially, he supported the SCL onshore works, and now he is responsible for preparing the TBM-Tunnels for the offshore SCL campaign.
