Product Description

Cutter suction dredger (CSD) is the core equipment of modern dredging engineering. It rotates and cuts the underwater soil layer with high-strength alloy cutter and cooperates with high-power mud pump to continuously transport the sediment mixture to the designated area through the pipeline. With modular design, this product integrates excavation, transportation, positioning and monitoring, and is applicable to deepwater operation and complex working conditions. The dredging volume per day can reach 3000-15000m ³, greatly improving the project efficiency.

1) Super excavation system

Wear-resistant reamer

titanium alloy teeth+ceramic coating, service life increased by 40%, gravel layer can be broken (particle size ≤ 30cm)

Depth coverage

standard excavation depth of 6-25m, deep-water version up to 35m (hydraulic lifting bridge)

2) Intelligent job control

Three-dimensional positioning

GPS+Beidou dual-mode positioning, plane error ≤ 10cm, depth error ≤ 5cm

AI production monitoring

real-time display of dredging volume, mud concentration and fuel consumption, and automatic generation

of construction report

3) Efficient conveying system

Mud pump cluster

series high-power mud pump, conveying distance of 500-5000m (apparent power configuration)

Anti-blocking design

intelligently adjust cutting speed and pump pressure to eliminate pipe blockage

4) Environmental protection and low disturbance

Environmental protection cutter cover

reduce the diffusion of suspended solids and reduce the turbidity of water by 50%

Electric drive option

meeting zero emission requirement of port (400V/6.6kV HV power supply)

5)All-weather operation

Anti-wind wave design

6-anchor positioning system resists 8-level wind waves, with operation stability far exceeding counterparts

Modular cabin

the cab/engine room is fully enclosed and thermostatic, supporting construction in extremely cold/high temperature

environment

1) Cost saving

Fuel consumption reduced by 30%, wear parts life extended by 40%

2) Rush the construction period

Hour continuous operation, construction period shortened by 50%

3

) Risk control

Intelligent anti-collision system, construction accident rate reduced by 90%

4) Sustainability

Conforming to IMO Tier III emission standard and CCS/CE environmental protection certification
