What is a cutter suction dredger and how does it work?

cutter suction dredger

A cutter suction dredger is a hydraulic dredger used for dredging operations in rivers, harbors, and other waterways. It consists of a dredging arm, or cutter head, that is attached to a rotating cutter shaft. Equipped with several cutter teeth, the cutter head loosens and cuts soil, rock, or other materials on the seabed or riverbed. The loosened material is then suctioned up into a dredge pump located at the bottom of the dredger, and pumped through a pipeline to a designated location. The cutter suction dredger is operated by a crew consisting of a captain, an engineer, and other support staff. The captain is responsible for navigating and positioning the dredger, while the engineer oversees the mechanical and technical aspects of the dredger.

Overall, the cutter suction dredger is an efficient and effective tool for dredging operations and is widely used in many different types of waterways around the world. If you're interested in dredging your harbor or marina, please feel free to contact us.
