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.
Hellyer Gold Dredge Hire
Dredge Dry Hire,
Mud/Silt/Sediment Removal / Relocation.
Hellyer Gold Mines hired a Neumann Contractors' designed and built 250mm cutter suction dredge, the ‘Nu-Investigator’ for 12 months to supplement the operations of their existing dredge in the site's tailings ponds. The hire agreement was a dry hire arrangement with Neumann Contractors providing experienced operators in the initial phase to train Hellyer’s operators in running the dredge.
Kingscoast Estate Project
Resource Mining,
Hydraulic Sand Transfer,
Civil Works.
The project was to hydraulically place 370,000 m3 of sand to raise the surface level of the Kingscoast Estate by 3 metres. The team dredged the sand from an adjacent sand quarry by the Nu Bounty, a 450mm bucketwheel cutter suction dredge combined 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. We achieved considerable savings and advantages over traditional methods.
Ernest Henry Mine Tailings Dredging
Tailings Removal/Transfer,
Tailings Reprocessing,
Re-Mining.
Ernest Henry Mining commissioned our 300mm CSD Nu Compact 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 processing circuit in which the magnetite was concentrated. The dredge operated on a 24/ basis while maintaining a consistent feed density to the processing plant.

Client Feedback
South Wavebreak Island Channel
Navigational Channel Maintenance, Beach Nourishment.
“Please pass on my thanks to your team. They did a great job, accommodated all our requests to board the vessel, provided quality feedback to Emma’s environmental questions and did the job quickly and efficiently which minimised impact to the stakeholders.
Additionally, the change you proposed to the placement methodology (going south to north) was the correct approach. I’m very glad we did not go north to south. I look forward to working with Neumann’s in the future on other campaigns.”
Ramsgate Baths Project
Beach Nourishment, Replenishment Works, Hydraulic Sand Transfer
“Thanks for arranging the quick collection of the Protective Fencing around the above Works and I am pleased to advise the Baths were reopened to the Public on Thursday. In fact, the Public were waiting just behind your Contractors so as soon as the last panels were removed, they charged into the Pool Area.
I wish to thank you and especially Josh for undertaking this project which have been overwhelming endorsed by the Public. I have received nothing but compliments from the Public and our Councillors on this Project. It was unfortunate I could not hold you here for more works once you were set up but now knowing how long it takes to set up hopefully in the not too distant future we can engage Neumann Dredging again for further beach nourishment works along our foreshore.”
Kinross Estate - Stage 9
ReclamationWorks, Hydraulic Sand Transfer, Civil Works, Capital Works.
“On time with no operational management issues during the works. Very easy contractor to manage as communication was forthcoming and easy. The contract was completed ahead of contracted schedule.
Open, frank and transparent communication made the optimum solution possible.”
