The Nu Explorer Series is a product of over 60 years experience in contract dredging, it is lightweight and compact but very powerful and efficient and it is quickly earning reputation for performance and reliability in channel maintenance dredging, capital works marine dredging and in mining and resource dredging. 

The dredge is demountable and can be cost effectively transported to remote sites around Australia and overseas. The use of this dredge has proven to be a safe and cost effective method on mine sites for the relocation or reprocessing of tailings.

The Nu Discovery Cutter Suction Dredge has been successfully used for the removal of sand, muds, silts, and slimes and mine tailings.

In harbour and river works, where a variety of natural and dumped materials might be encountered, Neumann dredges have proven their versatility.

Neumann’s extensive dredging experience also makes our dredges highly suited for a variety of material types often encountered in flood prevention and environmental rehabilitation works.

The Nu Discovery has worked on the following Projects:

Iluka Boat Harbour Dredging

Portas and Harbours,
Navigational Channel Maintenance,
River and Waterways,
Coastal Protection/Beach Nourishment.

Neumann Dredging was engaged by the NSW Govt. and Investment to undertake dredging works to the entrance channels for the Iluka Boat Harbour. The works involved the dredging of the two approach channels to the Iluka Boat Harbour up to a depth of -3.0m below Iluka Port Datum. The total volume of marine sediments dredged was approximately 26,000m3.

Cabbage Tree Point Dredging

Channel Maintenance

The Gold Coast Waterways Authority awarded us the project to dredge the Main Channel North at Cabbage Tree Point to a safe navigable depth. The works was undertaken by the cutter suction dredge Nu Discovery. The dredged sand and silt were used as beach nourishment on either side of the boat ramp, and in front of the houses.

Monreagh Dam Tailings Dredging

Tailings Storage Facility (TSF) Maintenance,
Sediment Removal.

The dredging works at Monreagh Mine involves the removal the sediment from the nominated dredge area in the pond at the site in Miles with the use of our 250mm cutter suction dredge the Nu Discovery. The dredge will be used to transport the material through a combination of 246 mm (ID) floating and land-based pipeline to the nominated disposal area in the opposite end on the pond.

Bellinger River Resource Dredging

Resource Dredging,
Sand Mining,
River and Waterways.

Coarse river sand from mined from the Bellinger River waterways in Coffs Harbour for HQ Sands using the Nu Discovery Cutter Suction Dredge. The sand was to be pumped approximately 1km and was discharged directly to the processing plant at their facility in Repton.
