Main engine power 1,193 kw 20 inch cutter suction dredger for port dredging
product description
Cutter suction dredger is a highly efficient and continuously working underwater excavation equipment, which is
widely used in the fields of channel dredging, port construction, land reclamation, water conservancy projects,
environmental dredging, etc. It integrates the functions of "excavation, transportation and discharge" and is one
of the main ship types in today's dredging projects.

Main workflow:
Excavation: A powerful auger head is mounted on the front or side of the hull. This huge rotating cutter head (usually
with cutting teeth) is lowered to the bottom of the water and rotates at high speed to cut, stir and crush the bottom
materials such as mud, clay and even soft rock.
Suction: The auger head is usually supported by a auger bridge, and a mud suction pipe is installed inside the bridge.
The suction port of the mud suction pipe is located just behind the auger head. When the auger head loosens the
bottom material,the powerful mud pump (centrifugal pump) on the ship starts to work, generating a strong vacuum
suction, sucking the mixture of water and loosened mud (called "mud") through the mud suction pipe.
Transport: The sucked mud is pressurized and transported through the mud pipe system inside the hull.
Discharge: The mud is finally transported to the designated location through the mud discharge pipe. There are
two main discharge methods:
Direct shore discharge/blowing and filling: The mud is directly transported to the land or shoal area to be filled
through a long mud discharge pipeline (floating pipe + shore pipe) connected to the stern of the ship.
Loading: The mud is discharged into the mud barge (mud transporter) docked next to the dredger, and transported
to the dumping area or filling area by the mud barge.
Main features:
Continuous operation: Excavation, suction, transportation and discharge are carried out continuously with very high
efficiency.
Wide application range: By changing the type of auger head, silt, sand, clay, gravel and even medium-hard weathered
rock can be excavated.
Long transportation distance: The powerful mud pump system can transport mud to several kilometers or even more
than ten kilometers away (even farther through relay pumping stations).
Relatively high excavation accuracy: The excavation depth and flatness can be controlled by adjusting the depth of
the auger bridge and the precise positioning system.
Controllable impact on the environment: Compared with some trailing suction dredgers (which need to open the
bottom to throw mud), the dredger can transport mud and sand to designated locations (such as filling areas)
more accurately through pipelines, reducing the impact on the ecology of the dumping area. Environmentally friendly
auger heads (such as basket auger) can also significantly reduce the spread of suspended matter.
application
1.Port and waterway construction
Deepwater channel excavation
New port foundation trench excavation
2.Land reclamation
Island construction by blowing (China used the "Tianjing" to build islands and reefs in the South China Sea, blowing
4,500m³ of sand and soil per hour).
3.Environmental governance
Cleaning of polluted sediments (such as dredging of blue algae sediments in Taihu Lake).
River ecological restoration (European Rhine River dredging project).
4.Mining and resource extraction
Subsea mineral mining (phosphate rock, tin sand, etc.).
