Work on the 4.9km long tunnel, which will be the longest gas pipeline tunnel in Europe has been ongoing since January 2013. 

Launching the booklet at the annual conference of ‘Engineers Ireland’ SEPIL Managing Director, Michael Crothers said that the story of the Corrib tunnel provided a compelling narrative of one of the most challenging engineering projects undertaken in Ireland in recent years.

“This brochure tells the amazing story of the Corrib tunnel. It highlights the unique engineering and environmental approaches adopted to minimise the impact on the community and the environment.  As an engineer myself, I hope that the story of the Corrib tunnel provides a valuable insight to engineers in Ireland and abroad as the industry seeks innovative engineering solutions to meet the energy challenge.”

The booklet features the tunnel boring machine (TBM) ‘Fionnuala’, which is 140m long, weighs 500 tonnes and comprises 14 sections, and took more than a year to design and build in Germany.  Since tunnelling commenced, the 28 tonne cutter head at the front of the TBM has been working around the clock drilling through rock, clay and sand.

John Power, Director General of Engineers Ireland said:  “The building of the Corrib tunnel is a remarkable project and a great example of engineering excellence in Ireland.  Many of our members have gained valuable experience from working on the tunnel and on the Corrib Gas Project.  I’m delighted that Shell E&P Ireland Limited has launched this brochure and I commend it to our members and anyone with an interest in engineering.”
