General Introduction:

The cutter suction dredger is a stationary dredger equipped with a cutter device(cutter head)which excavate the soil before it is sucked up by the flow of the the dredge pump.

During operation the dredger moves around a spud pole by pulling and slacking on the two fore sideline wires.This type of dredger is capable to dredge all kind of material and is accurate due to their movement around the spud pole.The stationary cutter suction dredger is to distinguished easily from the plain suction dredger by its spud poles,which the last don't have.

The spoil is mostly hydraulically transported via pipeline,but some dredgers do have barge-loading facilities as well.Cutter power ranges from *0kw up to ***0kw,depending on the type of soil to be cut.

Area of application:

Cutter suction dredgers are largely used in the dredging of harbours and fairways as well as for land reclamation projects.In such cases the distance between the dredging and disposal areas is usually smaller than the distance covered by trailing suction hopper dredgers.The cutter suction dredger also has the advantage when an accurate profile has to be dredged.The cutter suction dredger can tackle almost all types of soil,although of course this depends on the installed cutting power.Cutter suction dredgers are built in a wide range of types and sizes,the cutting head power ranges between *0kw for the smallest to around ***0kw for the largest.The dredging depth is usually limited;the biggest suction dredger can reach depths between *5 and *0m.The minimum dredging depth is usually determined by the draught of the pontoon.
