Case Studies

River Humber Gas Pipeline Replacement Project

Work has been carried out on a £100m project to create a tunnel under the River Humber to carry one fifth of the UK’s gas supply to millions of homes.
The three-mile tunnel houses a new gas pipeline running between Goxhill in North Lincolnshire and Paull in East Yorkshire and was expected to take a year to build. National Grid needed to replace the current pipeline, which is in a trench just below the river bed and is at risk of being exposed by the tides.
The crown of the TBM passed 7m underneath an existing in-service gas pipe, approximately 10” in diameter and a few hundred meters from the reception shaft on the Paull side. On this existing gas pipe in-service, three spots were monitored for changes in strain as the pipe falls in the zone of influence of the TBM.
