CONTRACTOR Murphy Pipelines has used Grundoram pipe-ramming kit to drive in steel pipeline sections on the Trans-Pennine gas pipeline.
The pipeline will extend for 52 km across Humberside, crossing beneath 23 roads, two rail lines, the river Hull and the Market Weighton Canal.
The pneumatically-driven Grundoram Goliath was brought in to ram home the 1,200 mm-diameter pipeline beneath roads and canals, where the ground conditions are unsuitable for conventional auger boring techniques.
Among the difficult conditions on the route were a 12 km run of chalk, together with gravel and peat sections.
The Goliath, supplied by Bedford-based TT UK, is supported by tracked side-booms to achieve average ram speeds of 30 m an hour on the 35-50 m sections.
