River Exe Gas Pipeline Installation
Energy infrastructure company National Grid needed install a 600mm diameter gas pipe through a 1.8km bored tunnel under the River Exe between Lympstone and Powderham as part of a major project to improve the region’s gas supplies. In conjunction with specialist contractor Expanded we developed an installation method that involved strand jack pulling the gas pipe through the tunnel on roller supports. We designed the necessary temporary works and checked the stresses in the pipe during installation to make sure it was not damaged.
