TSHD Shoalway to make space for Everton’s new stadium

Royal Boskalis Westminster recently kicked off work on another interesting land reclamation project, pumping sand into the Bramley-Moore Dock to make space for Everton’s new stadium.

Over the next three months, the company’s hopper dredger Shoalway will deliver over 450,000 cubic metres of dredged sand from Liverpool Bay and the Irish Sea to the Bramley-Moore Dock.

Everton’s Stadium Development Director, Colin Chong, said: “This is a huge maritime engineering project and, in many ways, the very laying of the foundations for the new stadium. All the preparatory work so far, in raking the dock bed of unwanted materials and the relocation of marine life, has led to this important stage and now the dock itself has been sealed, work has begun on filling the dock.”

“A trailer dredger is connected to a discharge pipeline floating on the surface of the shore, and the sand is then fluidised in a hopper then hydraulically pumped, via the pipeline, over the River Mersey wall to a spreader pontoon within the dock,” added Chong. “This pontoon will then evenly distribute the sand within the dock and displace the water into a neighbouring dock and this continues until the reclamation of land is above the original dock water level.”

Once the dock is infilled with sand, a controlled process will consolidate the upper six metres by dropping a nine-tonne weight, at a frequency of 60 times per minute.

The resulting compacted and rolled surface will then be suitable for the piling process, which begins early next year. This will form the sub-structure of the new 52,888-capacity stadium.
