Main features

Integrated system

Integrated dredge pump and drive system (CSD 400 & 450)

Cutter Suction Dredger 450 is designed with an integrated dredge pump & drive system. This means that the dredge pump is coupled with the gear box, which is coupled with the engine. As a result, the dredger is highly efficient & compact.

Shallow draft

CSD 450 Shallow Draught

CSD 450 has a shallow draft of 1.4m. This is due to its three pontoon design – one central and two on the sides. The pontoons provide this floating capacity, which allows the dredger to easily operate in shallow waters.


CSD 450 dismountable

This dredger can be taken apart into one central pontoon, two side pontoons, a control cabin, the spuds and the cutter ladder. Due to CSD 450 dismountable design, it is practical for transport and storage.

Exchangeable cutter teeth

CSD 450 includes cutter teeth that can be easily interchanged between three different types depending on the material to be dredged, or replaced when worn out. This process is easy due to bolt connection used to attach cutter teeth to the cutter head.

Extendable depth

Cutter suction dredger 450 features a maximum dredging depth of 10m. Upon request, this can be extended to 14m through an additional adapter placed in between the dredge pump and the cutter head system.
