This contract required the installation of temporary sheet piled cofferdams and trench retaining walls for the landfall works of the 468km long 34" SEAL gas pipeline connecting the Elgin/Franklin offshore gas fields to Bacton, Norfolk.
The piles were installed using our resonance free leader rig and impact driven to the required toe level through the dense sands using a 2.4t hydraulic impact hammer suspended from our 50t crawler crane.
