The Port of Liverpool in the UK has achieved a milestone in the construction of a new £300m ($500m) container terminal after the work to reclaim 12 hectares of land passed the first stage.
The port has placed the majority of 296 steel piles into the seabed and it resulted in the infilling of 1.43 million tonnes of sand and silts deposited behind the new quay wall, up to a level of more than 6m above ordinary datum.
This new terminal, named Liverpool2, will have the capacity to accommodate 95% of the world’s container fleet, including the post-Panamax vessels.
Liverpool2 construction director Doug Coleman said: "We can only carry out the installation of anchor blocks and other infrastructure, including vibrocompaction, for a maximum of eight hours each day, two hours either side of each low tide. The one benefit is that the weight of water during high tide helps to compress the infilled material.
"The tide also means that for every million tonnes we bring in, we lose about 2.5%, which is not significant in the scheme of things and is helped by our deliberate strategy of installing the new sewerage outfall pipe which acts as a barrier to minimise losses."
The piling process started in 2014. It is expected to be completed in the next few months. The remaining work includes the drilling from large jack-up rigs and inserting tubular piles to create a new 854m long quay wall.
Liverpool 2 will connect directly to a number of port-centric logistics hubs along the Manchester Ship Canal via barge.
Construction of the terminal is scheduled to be completed in December .
