Featured Dredging Projects

Sydney Water Desalination Project

Capital Works Dredging,
Ports and Harbour,
River and Waterways Dredging.

Dredging works associated with the Botany Bay pipeline crossing, which was part of the construction of Sydney’s DeSal plant at Kurnell, Southern Sydney. When completed water from the desalination plant will be piped to the City Water Tunnel at Erskineville. This is part of the Potts Hill Water system, which services areas south of Sydney Harbour, to Bankstown in the west and Sutherland in the south.

Ernest Henry Mine Tailings Dredging

Tailings Removal/Transfer,
Tailings Reprocessing,

Our 300mm CSD Nu Compact was commissioned by Ernest Henry Mining to reprocess/remine the tailings from the Tailings Storage Facility (TSF) to recover magnetite. The Nu Compact pumped the reclaimed tailings via a 1000 metre long HDPE pipeline directly into a process circuit in which the magnetite was concentrated. The dredge operated on a 24/ basis while maintaining a consistent feed density to the processing plant.

Broadwater Parklands

Nav. Channel Maintenance,
River and Waterways Dredging,
Reclamation Works,
Beach Nourishment.

We were engaged by the Gold Coast City Council and the Gold Coast Waterways Authority to undertake reclamation works required for the Broadwater Parklands Stage 3. Clean sand was dredged from nearby navigational channels in the Gold Coast Broadwater for the Reclamation Works. The cutter suction dredges Nu Enterprise and Nu Compact were used for this dredging project.

Kingscoast Estate Project

Resource Mining,
Hydraulic Sand Transfer.

The project was to hydraulically place 370,000 m3 of sand to raise the surface level of the Kingscoast Estate by 3 metres. The sand was dredged from an adjacent sand quarry by the Nu Bounty, a 450mm bucketwheel cutter suction dredge in combination with a 500mm, 2,000 hp booster pump. The slurry was pumped distances up to 2,000m through a 560mm poly pipeline to the estate. Considerable savings and advantages were achieved over traditional methods.
