Characteristics and advantages of cutter suction dredgers

Characteristics and advantages of cutter suction dredgers:

1. The large cutter suction dredger is equipped with a self-propelled system
Large cutter suction dredgers can navigate to their designated location during relocation. 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.

2. The cutter suction dredger has good economic efficiency
The excavation and transportation of materials can be completed in one go, without the need for other ships to cooperate, and multiple handling can be achieved. Relatively lower engineering costs. Large production capacity and long pump distance. Large cutter suction dredgers can produce several thousand cubic meters per hour; By relying on strong power, sediment or crushed rock materials are pumped out thousands of meters away through mud pumps and discharge pipelines.

3. The cutter suction dredger has a wide range of applications
It can be used for dredging, channel excavation, and land reclamation in rivers, lakes, and seas. In special circumstances, high-power cutter equipment can be installed on the cutter suction dredger to excavate rock formations such as basalt and limestone without the need for blasting.

4. The winch suction boat 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.
