Dredging Vessels

Sediment removal by breaking up hard soils with a rotating cutter head

  • Dredging depth: up to 18 meters

The Cutter Suction Dredger is a widely used vessel in dredging projects. Its operation works by using a rotating cutter head to loosen the soil at the riverbed or seabed, turning it into a slurry mixed with water. This slurry is then sucked into the pump through the suction pipe and pumped out through the discharge pipe to the designated disposal area, completing the dredging, transport, and discharge process in one integrated operation.

Applications
  • Coastal Dredging
  • Offshore Channel Widening
  • Inland River Dredging
  • Reservoir Dredging
  • Tailings Pond Dredging
  • Dock Dredging
  • Inland Sand Mining

Features
  • High Efficiency: With integrated dredging, transporting, and discharging functions, our vessels can operate continuously, resulting in higher production efficiency.
  • Precise Dredging: Equipped with Siemens PLC control systems, the vessel can perform precise dredging in specific areas with accurate contouring using the cutter head control and positioning system.
  • Strong Adaptability: Capable of working in various soil conditions, our dredgers can handle different types of cutters to dig sand, sandy loam, silt, and more. They perform well in calm inland rivers, lakes, and coastal ports with low currents and minimal waves.
  • Cost-Effective: Our dredgers complete excavation and transportation in a single step, eliminating the need for multiple vessels and reducing overall project costs.
