2. Brief Introduction of dredger

A cutter suction dredger's (CSD) suction tube has a cutting mechanism at the suction inlet. The cutting
mechanism loosens the bed material and transports it to the suction mouth. The dredged material is
usually sucked up by a wear-resistant centrifugal pump and discharged either through a pipe line or to
a barge.Cutter suction dredgers are most often used in geological areas consisting of hard surface
materials (for example gravel deposits or surface bedrock) where a standard suction dredger would be
ineffective. They can, if sufficiently powerful, be used instead of underwater blasting.
