240m3h  Capacity Cutter Suction Dredger with Advanced Control System

product description

Cutter Suction Dredger (CSD) is a highly efficient underwater dredging vessel that cuts riverbed/seabed soil with a rotating auger and then transports the mud to the designated area through a powerful pumping system. It is widely used in large-scale projects such as port construction, channel dredging, and land reclamation, and is known as the "flagship equipment" in the dredging field.

product parameters

Core working principle
Reamer cutting system

Reamer head: A rotating cutter disc is installed at the front end, and the cutter teeth are made of high-strength alloy steel, which can cut rocks, corals, hard clay, etc.

Ladder: The hydraulic system controls the depth and horizontal swing angle of the reamer to achieve precise excavation.

Mud suction system

Centrifugal mud pump: The hull is equipped with a high-power mud pump to generate negative pressure to suck the mud and water mixture after cutting.

Mud pipeline: Mud is transported to the mud dumping area several kilometers away through floating or underwater pipelines Positioning and movement

Positioning pile system: Two hydraulic steel piles are alternately inserted into the riverbed to push the hull forward like a "looper"

Auxiliary anchor machine: The ship position is adjusted through multiple anchors in complex waters.

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.).
