Cutter Suction Dredger
Sediment removal by breaking up hard soils with a rotating cutter head
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.
