Nu Endeavour
Cutter Suction Dredge
Nu Endeavour Cutter Suction Dredge
The Nu Endeavour Cutter Suction Dredge is a Neumann Series 350 Series dredge built by Neumann Equipment in the 1980s. Since then, it has undergone numerous refurbishments, upgrades and improvements. The operational expertise built on our contract dredging experience enables us to improve our equipment constantly. This culture of innovation gives us the leading edge as dredging contractors of choice.
The Nu Endeavour has evolved into a high technology cutting and recovery machine and has a well-earned reputation for performance and reliability in channel maintenance dredging, capital works marine dredging, and mining and resource dredging.
The dredge is demountable and can be cost-effectively transported to remote sites around Australia and overseas. In addition, 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 Endeavour Cutter Suction Dredge has successfully removed sand, gravels, clays, muds, silts, slimes, weathered rock, and mine tailings.
In harbour and river works, where the cutter suction dredge might encounter a variety of natural and dumped materials, Neumann dredges have proven their versatility.
Neumann’s extensive dredging experience makes our dredges highly suited for various material types often encountered in flood prevention and environmental rehabilitation works.
The Nu Endeavour has worked on the following Projects:
- Coomera River Dredging Channel Maintenance Dredging,
- Maroochy Dredging and Beach Nourishment,
- South Channell and South Wavebreak Island Channel Maintenance Dredging,
- Burnett River Channel Maintenance Dredging,
- Penrith Lakes Mining and Resource Tailings Dredging,

The Nu Endeavour has worked on the following Projects:
Maroochy Dredging Beach Nourishment
Navigational Channel Maintenance,
River and Waterways,
Coastal Protection/Beach Nourishment.
The Sunshine Coast Council (SCC) required additional dredging in the Maroochy River. The sand was needed for the replenishment of beaches. The 450mm Cutter Suction Dredge the “Nu Endeavour” was used to dredge 20,000m3 of sand from the Maroochy River. With the aid of a booster pump, the material was transferred through an existing 400mm diameter pipeline located in the dunes.
Townsville Marine Project
Ports and Harbours,
Rivers and Waterways.
Stage 1 of the Townsville Marine Precinct was an$88 million dollar extension of the Port of Townsville, designed to establish a world class facility for marine related industries. This was a design and construct project completed as an alliance with the Port of Townsville Limited and Laing O’Rourke (LORAC).
Maroochy Replenishment Dredging
Navigational Channel Maintenance,
River and Waterways,
Coastal Protection/Beach Nourishment.
The Sunshine Coast Council (SCC) required the dredging of sand within the Maroochy River. This involved the mobilisation of the 450mm Cutter Suction Dredge the “Nu Endeavour” through the Maroochy River mouth and the dredging of 75,000m3 of sand through an existing 400mm diameter pipeline located in the dunes.
Bulga Mine Dredge Trial
Coal Tailings Relocation,
Mud Removal /Relocation.
Bulga Coal Management engaged Neumann Dredging to undertake a dredging trial to determine the feasibility and confirm the design of the tailings delivery system for a significant coal tailings relocation project. The test successfully demonstrated that the coal tailings could be efficiently and consistently pumped at slurry density concentrations from 0% to 45% using the Nu-Endeavour cutter suction dredge.
Lake Illawarra Channel Entrance Dredging
Navigational Channel Maintenance,
River and Waterways,
Coastal Protection/Beach Nourishment.
The Lake Illawarra project involved dredging the channel entrance to create a 1050m long x 100m wide channel. Sand dredged from the entrance was used for beach nourishment at the southern end of Warilla beach, 1.5 km away. Additionally, a sand island was to be created as a roosting area for local and migratory birdlife.
Moura Mine Tailings Dredging
Navigational Channel Maintenance
Nu-Endeavour was chosen to reclaim coal tailings from the Moura 2C pit. The plant processed these tailings to recover the fine coal lost in earlier operations, and it was part of a program to empty the pit to enable ongoing mining underground from the pit floor. The client required the dredge to produce 450 tonnes per hour of coal tailings and pumped distances of up to 2.5km to the processing plant.
Canaipa Passage Dredging
Navigational Channel Maintenance,
River and Waterways,
Coastal Protection /Beach Nourishment.
The Gold Coast Waterway Authority commissioned Neumann Dredging to dredge 30,000m3 of sand from Canaipa Passage in the Gold Coast Broadwater. We used the Neumann Equipment Designed and manufactured cutter suction dredge, Nu Endeavour to complete the dredging works. A spreader barge was used at Slipping Sands to distribute the sand evenly.
Coomera River Dredging
Navigational Channel Maintenance,
River and Waterways Dredging,
Resource Dredging.
Synergy Resource Management engaged Neumann Dredging to undertake the dredging of the upper sections of the Coomera River. The dredging involved removing 40,000m3 of marine sediments of various depths from an area covering 5,400 metres of the Coomera River upstream of Sanctuary Cove.
Bundaberg Burnett River Dredging
Navigational Channel Maintenance,
River and Waterways,
Coastal Protection /Beach Nourishment.
Severe flooding impacted the Burnett River, causing sedimentation in the navigational channels and erosion of the river banks. The team dredged the marine channels adjacent to Kirby’s Wall and replenished the eroded banks of the river with the sand, silt and sediments. The cutter suction dredge Nu Endeavour and a spreader barge completed the navigational channel maintenance, and nourishment works.
Bundaberg Port Dredging
Ports and Harbours,
Navigational Channel Maintenance,
Rivers and Waterways,
Coastal Protection /Beach Nourishment
Recently the Port of Bundaberg was significantly impacted by flooding, which caused unprecedented siltation in the port channel, swing basin and berth pockets. The maintenance works in the affected channels and port areas was undertaken by the cutter suction dredge Nu Endeavourin. In addition, the dredging team transferred the sand to a spreader barge, where the sand was able to be used as beach nourishment material.
Penrith Lakes Tailings Dredging
Tailings Storage Facility (TSF) Maintenance
The project involved dredging of approximately 1,300,000m3 of sand, silts and clays from a central tailings storage facility to a land reclamation site 4.4 km away. The materials are being placed in a manner which enabled the coarser fractions of the tailings to be separated from the silts and clays.
South Channel Dredging
Navigational Channel Maintenance,
River and Waterways,
Coastal Protection/Beach Nourishment.
Neumann Dredging were engaged by the Gold Coast Waterways Authority for complete maintenance dredging works for the dredging of the South Channel and South Wavebreak Island Channel, on the Gold Coast, Queensland. The works involved the dredging the nominated shallow areas of the primary South Navigation Channel and the secondary South Wavebreak Island Channel.
South Wavebreak Island Channel Dredging
Navigational Channel Maintenance,
River and Waterways,
Coastal Protection/Beach Nourishment
This project aims to return the North, South and South Wave Break Island (NSWI) navigation channels in the Southern Broadwater to their minimum safe design depths by removing identified shoaling. Dredged sand will be used to mitigate severe erosion on the northern Wave Break Island rock wall and eastern beach as well as on the Spit ‘Finger’.
