Highlight:
Cutter suction dredger with water flow of 4800m3/h is used for river dredging
product description
Cutter Suction Dredger (CSD) is a highly efficient underwater excavation and dredging vessel, mainly used for channel
dredging, port construction, land reclamation, river management and other projects. It uses a rotating auger to break
up underwater soil or rock, and then uses a powerful mud pump to transport the broken mixture (mud) to a designated
location through a pipeline.
Core Components
Cutter Head
Located underwater at the bow, it is equipped with carbide teeth that can rotate to cut/crush seabed mud, clay, gravel
and even rocks.
Different knife types (such as rock drills and dredgers) are designed according to geological conditions.
Suction Pipe & Dredge Pump
The material crushed by the cutter is sucked into the pipeline, sucked and pressurized by a high-power centrifugal pump
(dredge pump).
Ladder
The lifting structure that supports the cutter and suction pipe controls the excavation depth through an articulated arm (up
to 30 meters underwater).
Positioning System
Anchoring positioning: Anchor cables are laid around the hull, and the position is adjusted by retracting and releasing
(traditional method).
Pile positioning: Two steel piles are set at the stern and inserted into the riverbed alternately, and the hull is swung left
and right with the piles as the fulcrum (suitable for narrow waters).
Dynamic Positioning (DP): Advanced ships use GPS+thrusters to automatically maintain position (accurate and efficient).
Discharge Pipeline
A floating pipe or submerged pipe is used to transport mud to a landfill or dump several kilometers away.

Technical features
Efficient and continuous operation: excavation, suction, and transportation are integrated, and the average daily
dredging volume can reach tens of thousands of cubic meters.
Adapt to complex geology: the auger is replaceable to cope with different working conditions such as soft mud and
hard rock.
Environmental protection and precision: reduce water disturbance, and cooperate with GPS to achieve centimeter-
level precision excavation (such as channel repair)
