The cut material together with a large quantity of water is drawn into the suction mouth. The cutter suction dredger moves forward by means of the spud carriage. By pulling on the side wires, the cutter head is moved sideways, swinging around the main spud. Boskalis deploys cutter suction dredgers in the construction and maintenance of ports, land reclamation and coastal defenses, and riverbank protection, and in dredging trenches for pipelines.Ī cutter suction dredger is positioned on spuds and anchor winches to ensure the vessel is firmly anchored during dredging. These powerful cutter suction dredgers are used in dredging rock, clay, silt and sand. Boskalis has cutter suction dredgers (CSDs) that are either self-propelled vessels or stationary dismountable vessels equipped with a rotating cutter head.
