Liverpool2 will be the most centrally located deep water container terminal in the UK with a £300m investment programme to expand and develop the Port of Liverpool will double its capacity and transform the port into one of the most modern and operationally efficient terminals in Northern Europe.
The project will create a new quay some 854m long from the South West corner to the Royal Seaforth Dock and involve the formation of a berthing pocket on the seaward side wall using dredge material as a permanent fill.
Scope of Works
BAM Nuttall and Van Oord under a JV had to carry out deep excavation and underwater demolition works to widen the dock, piling for the new quay wall construction with dredging and revetment works to allow installation of a new sea outfall pipe. Heavy excavation works would also be needed to construct a retaining structure for the fill material pumped ashore from a suction dredger.
Due to the scale of the project, WM Plant Hire used their 60 tonne and 85 tonne CAT long reach machines over two visits to clear obstructions from the seabed and excavate trenches for the outfall structures, including dredging and breaking out using an underwater breaker. The 85 tonne excavator was fitted with GPS equipment to carry out the dredging works with Van Oord, working from a barge out in the estuary and ensuring the outfall pipe was place accurately underwater.
