1. The cutter suction dredger is widely used and can operate in rivers, lakes, and seas for dredging, channel excavation, and land reclamation.

2. The cutter suction dredger has high work efficiency, large output, and long pump distance. Large cutter suction dredgers can produce several thousand cubic meters per hour; By relying on strong power, sediment is pumped out thousands of meters away through mud pumps and discharge pipelines.

3. The cutter suction dredger is easy to operate and control. The dredger relies on the trolley at the stern of the ship to position and step the steel piles. It uses the winch arm to measure the two steel cables and anchors fixed to the two measuring points of the excavation trench, and is pulled by the winch. The two compartments swing and cut the sediment material, and work under a certain controlled swing angle. The twisted material is pumped through the mud conveying pipe to the stacking yard. The stepping of a dredger is achieved by alternating the movement of two piles and taking a step forward.

4. The large cutter suction dredger is equipped with a self-propelled system, which can navigate to its designated location during migration. Small and medium-sized dredgers are mostly unmanned systems and rely on tugboats for towing. Small and medium-sized dredgers can be designed and constructed as assembled units, transported to the site by land, and can be used after assembly.

5. The cutter suction dredger has good economic efficiency. The excavation and transportation of materials are completed in one go, without the need for other ships to cooperate, with several handling operations. Relatively lower engineering costs.
