Product Description

Cutter Suction Dredger is a common and important engineering ship, widely used in the fields of channel dredging,

port construction, land reclamation, etc.
Working Principle
The working principle of the cutter suction dredger is based on mechanical cutting and hydraulic transportation.

The sediments such as mud, rock and so on on the bottom of the water are cut and crushed by the rotating augerdevice,

and mixed with water to form mud. Then, the suction generated by the mud pump on the ship is used tosuck the

mud through the suction pipe, and then transport it to the designated location through the mud dischargepipe, such

as the yard or other storage area on the shore.

product parameters:

Structural composition
Cutter bridge: It is equipped with a auger head and is a key component for excavating underwater sediments. The

height of the auger bridge can be adjusted by the lifting device to adapt to different excavation depths.
Mud pump: Provides power for the suction and transportation of mud. The performance of the mud pump directly

affects the production efficiency and transportation distance of the dredger.
Suction pipe and mud discharge pipe: The suction pipe is used to suck the mud cut by the auger into the ship,

and the mud discharge pipe transports the mud to the designated discharge location. The mud discharge pipe can

be a rigid pipe or a flexible pipe, which is selected and arranged according to actual needs.
Hull: provides support and buoyancy for the entire dredger, and is also a working platform for various equipment

and personnel. The design and structure of the hull need to take into account factors such as stability, navigation

performance and carrying capacity.
Power system: provides power for equipment such as cutters and mud pumps, usually including diesel engines,

electric motors, etc. The power of the power system depends on the size of the dredger and the operating requirements.
Control system: used to control parameters such as the rotation speed of the cutter, the lifting and lowering of

the bridge, and the flow rate of the mud pump to achieve precise excavation and transportation operations. Modern

cutter suction dredgers are usually equipped with advanced automated control systems to improve operating efficiency

and accuracy.

Advantages
High excavation efficiency: The rotary cutting action of the cutter can effectively crush and excavate various types

of sediments, including hard rocks and dense clay, greatly improving the excavation efficiency.
Long transportation distance: The powerful mud pump can transport mud to a long distance to meet the needs of

different projects. The mud discharge distance of some large cutter suction dredgers can reach several kilometers or

even farther.
High excavation accuracy: Through the precise control system, the excavation depth, width and slope can be precisely

controlled to ensure the quality of the project.
Strong adaptability: It can operate in different water environments, such as rivers, lakes, ports, oceans, etc., and

can adapt to different geological conditions.
Good environmental performance: Compared with some other dredging methods, the noise and vibration generated

by the cutter suction dredger are relatively small, and the impact on the surrounding environment is relatively small.

At the same time, the mud transportation process is closed, which reduces the pollution to the water body.
Limitations
Affected by wind and waves: In sea areas with strong winds and waves or in severe weather conditions, the operating

stability of the cutter suction dredger will be affected, and it may even not operate normally.
High requirements for ship positioning: In order to ensure excavation accuracy and transportation effect, an accurate

ship positioning system is required. In some complex water environments, ship positioning may be subject to certain

restrictions.
Large initial investment: The equipment purchase cost of the cutter suction dredger is high, and it also requires supporting

auxiliary equipment and facilities, such as mud discharge pipes, transport ships, etc., which increases the initial investment.
Application scenarios
Channel dredging: Maintain the water depth and width of the channel to ensure the safe passage of ships. Regular

dredging of the channel can remove the silt and improve the navigation capacity of the channel.
Port construction: In the construction, expansion and renovation of the port, the cutter suction dredger is used to

dig the harbor, channel and dock foundation to provide the necessary site conditions for the construction of the port.
Land reclamation: New land is formed by blowing the silt on the seabed into the designated area. This method is

widely used in land development and industrial park construction in coastal cities.
Water conservancy projects: In the construction and maintenance of water conservancy facilities such as reservoirs

and rivers, the cutter suction dredger can be used to remove reservoir siltation, widen the river channel, and strengthen

the dam.
Mineral mining: In the mining of mineral resources in some offshore or inland rivers, the cutter suction dredger can

be used to dig and transport silt containing minerals to realize the mining and utilization of mineral resources.
