Highly efficient, high-output dredging vessels with long pumping distances. They offer several advantages:
*High Efficiency and Output: These dredgers can handle thousands of cubic meters of flow per hour, reaching depths of up to 30 meters. They can excavate and transport 1,200 cubic meters of soil, sand, and gravel per hour (equivalent to 6,000 cubic meters of slurry).
*Long Pumping Distance: Powerful pumps and discharge pipelines enable them to transport dredged material up to 4 kilometers away.

How they work:
Cutter suction dredgers, also known as cutter suction dredgers, are custom-designed vessels. They utilize a hydraulically powered cutter head to excavate and agitate soil and sand, creating a slurry. This slurry is then sucked up by a slurry pump and discharged to the designated location through pipelines.

Versatility and Applications:
Due to their adaptability to various channel sizes and working conditions, cutter suction dredgers are widely used. They offer a continuous dredging process, integrating excavation, transportation, discharge, and treatment in a single operation. This efficiency has led to their widespread adoption, making them a preferred choice for many construction companies.

Cutter suction dredgers are suitable for:
*Operations and deployment in Class B and C waterways, including seas and rivers.
*Dredging, excavation, maintenance dredging, and embankment reinforcement in channels, harbors, and lakes.
*Dredging and reclamation in small and medium-sized reservoirs.
Waterway construction, farmland irrigation, flood control, and drainage projects.

Efficiency and Cost-Effectiveness:
Cutter suction dredgers are widely used in dredging projects due to their efficiency. They utilize a rotating cutter head at the suction pipe's inlet to cut and agitate sediment. The dredged material is then transported to the disposal site through the suction pipe using powerful pumps. This integrated process of dredging, transporting, and unloading makes them highly efficient and cost-effective underwater excavation tools.

Customization and Availability:
Cutter suction dredgers are typically custom-built to meet specific client requirements. However, readily available models range from 4 inches to 20 inches, offering transparency in configuration and pricing.
Example Vessel:
A typical non-self-propelled, steel, box-shaped, trimaran cutter suction dredger features:
---A bow gantry for opening and closing.
---Two stern piles for positioning, with the main pile equipped with a mobile trolley.
----Coordinated operation of the bow's transverse cutter movement and the stern positioning piles for dredging and moving.
---Full hydraulic control system.
---A low-speed, high-torque hydraulic motor driving the cutter head through a gearbox.
---High-quality double-row spherical roller bearings supporting the cutter shaft.
---Three diesel generator sets: the main one powering the submersible slurry pump, the auxiliary one providing power for the hydraulic system, and the harbor generator supplying electricity for vessel maintenance and daily life.
