Dredge Spec Sheet

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 constantly improve our equipment. This culture of innovation gives us the leading edge as dredging contractor 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 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 Endeavour Cutter Suction Dredge has been successfully used for the removal of sand, gravels, clays, muds, silts, slimes, weathered rock, 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 Endeavour has worked on the following Projects:

Dredge 6 - Nu Endeavour Cutter Suction Dredge

The Nu Endeavour has worked on the following Projects:

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 cutter suction dredge Nu Endeavour was used to complete the maintenance works in the affected channels and port areas. The sand was transferred 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.

Moura Mine Tailings Dredging

Navigational Channel Maintenance

Nu-Endeavour was chosen to reclaim coal tailings from the Moura 2C pit. These tailings were processed 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 dredge was called upon to produce 450 tonnes per hour of coal tailings, which were pumped distances of up to 2.5km to the processing plant.

Canaipa Passage Dredging

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

Neumann Dredging were commissioned by the GC Waterway Authority to dredge 30,000m3 of sand from Canaipa Passage in the Gold Coast Broadwater. The dredging was completed using Neumann Equipment designed and built 450mm cutter suction dredge the Nu-Endeavour. The sand was transferred to spreader barge where is was used as beach nourishment at Slipping Sands.

Lake Illawarra Channel Entrance Dredging

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

The Lake Illawarra project involved the dredging of 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, approx. 1.5 kms away. Additionally, a sand island was to be created as a roosting area for local and migratory bird life.

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).

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’.

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 the removal of 40,000m3 of marine sediments of various depths from an area covering 5.4 kilometres of the Coomera River upstream of Sanctuary Cove.

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.

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.

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.

Bulga Mine Dredge Trial

Coal Tailings Relocation,
Mud Removal /Relocation.

Neumann Contractors were engaged by Bulga Coal Management to undertake a trial to determine the feasibility and confirm the design of the tailings delivery system for a significant coal tailings relocation project. The dredge trial scope included, Modifying the ‘Nu-Endeavor’ from an anchor boom and spud-controlled dredge to a three-wire dredge, testing whether the tailings material could support the use of anchor booms and spuds. Testing shore-based anchoring options if the tailings could not support anchors. Testing a range of pumping densities to confirm the overall system design. Confirming the maximum slurry density, the dredge could achieve

Bundaberg Burnett River Dredging

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

The Burnett River was severely impacted by flooding. The navigational channels adjacent to Kirby’s Wall were dredged and the sand, silt and sediments was used as beach nourishment on the eroded banks of the river. The cutter suction dredge Nu Endeavour and a spreader barge were used to complete the channel maintenance and nourishment works.
