We are experienced in Designing and Building Cutter Suction Dredgers
Dredgers We Build
A cutter suction dredger (CSD) is a hydraulic dredger that uses centrifugal pumps with a rotating cutter head to loosen, lift and transport dredged material.
Cutter suction dredgers may:
- have a pontoon hull without a means of propulsion (non-propelled), or
- be self-propelled, sea-going specially designed vessels.
Whether self-propelled or not, the cutter will be moored with spuds or anchors while at work so that in essence the dredging operation takes place with the cutter in a stationary position.
Small and medium size cutter suction dredgers can be dismountable and transportable over land. The hull is then composed of a series of pontoons, with the one pontoon containing the machinery.

Advantages of using CSD for Dredging
Advantage
The most powerful cutters can dredge hard rock effectively on a continuous basis. The self-propelled CSDs can travel long distances and be deployed in remote locations, far from their home port, making them flexible to be used all over the world. They can work in shallow waters and they also have flexible discharge alternatives.
