Following the successful completion of the temporary works, Tas Marine was awarded the contract to deliver the full Bellerive Stormwater Upgrade — the City of Clarence’s largest infrastructure project to date.
The upgrade involved constructing a sheet pile cofferdam across Bellerive Beach to enable trench excavation for the new sewer outfall. Tas Marine mobilised its jack-up barge with a 22t excavator for seaward dredging, alongside a 26t excavator with a sheet pile vibrator on the land side. More than 200t of sheet piles and steel struts were installed to form the temporary structure, which was removed once the outfall pile was completed.
Now fully operational, the new stormwater system at Beach Street significantly reduces flood risk to surrounding roads and properties during heavy rainfall.
Tas Marine is proud to have delivered this critical project with a strong focus on protecting the local environment and community. Working closely with the City of Clarence and stakeholders, the team implemented strict environmental protocols to minimise disruption to the marine environment, safeguard coastal ecosystems, support long-term sustainability goals for the region, and build greater resilience for the community.

Tas Marine was contracted to deliver the temporary works for the Bellerive Stormwater Outfall. A sheet pile cofferdam was installed to enable safe excavation of a trench across Bellerive Beach for the new sewer outfall.
The works involved mobilising Tas Marine’s small jack-up barge with a 22t excavator for seaward dredging, alongside a 26t excavator with a sheet pile vibrator on the land side. In total, 200t of sheet piles and steel struts were used to form the temporary structure, which was successfully removed just one week after the outfall pile was installed.

Replace timber jetty with concrete wave panels with reinforced concrete jetty and new wave panels. New wave panels were 4m deep and were supported on two rows of heavy steel UC’s bolted back to the piles. Difficult logistics of building a large structure 10 NM off shore from the east coast. Very exposed site to prevailing westerlies made construction difficult.

Excavating materials form port and marina to improve draft for berths and access into the port.
Materil was a mixture of mud, sand, loose rock and sandstone bedrock. The hard sandstone bed rock had to be broken with a rock-breaker operating underwater before it could be dug out.
Material was stockpiles in the carpark and allowed to dry. The council is planning on using the dredged material for land reclamation elsewhere in Triabunna shortly.
