Sydney Overseas Passenger Terminal, Circular Quay

The overseas passenger terminal at Sydney’s circular key was a complex and highly technical steel piling project.  The Contractor manufactured a specialised piece of machinery enabling the steel sheet piles to be installed and driven underwater without submerging the hammering mechanism. Piling Solutions Australia also designed and supplied the steel piling with the required yield strength of 430Mpa using product PSZ26-700.

The NSW Port Authority found that the newer and larger vessels entering the harbour and docking at the terminal were eroding away the seabed adjacent to the existing seawall. The newer vessels are fitted with larger side bow thrusters known as azipods. The force of the water from the azipods was undermining the existing wall and ultimately increasing the risk of structural failure of the wharf.
