A Cutter Suction Dredger​ in Large-Scale River Dredging Projects is commonly selected because it combines underwater cutting, slurry suction, and material transportation capabilities in one integrated dredging system.

Cable dredges are specialized dredging machines designed for underwater excavation, sediment removal, and material recovery projects. Unlike self-propelled dredging equipment, cable dredges usually operate through a cable positioning system that controls the movement and working range of the dredging unit.

Dredging equipment is widely used in river maintenance, wetland restoration, mining, port construction, and sediment removal projects. Among the most common equipment categories are amphibious dredgers and conventional dredgers. While both are designed for dredging operations, they differ significantly in mobility, working environment, transport capability, and operational flexibility.

A cutter suction dredger (CSD)​ is one of the most widely used dredging machines for river maintenance, sand excavation, mining operations, port construction, and slurry transport projects. Known for its strong excavation capability and continuous pumping system, the cutter suction dredger is designed to remove sediment, sand, mud, and slurry efficiently from underwater environments.
