Introduce

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

During operation the dredger moves around a spud pole by pulling and slacking on the two fore sideline wires. This type of dredger is capableto dredge all kind of material and is accurate due to their movement around the spud pole.

The ladder, the construction upon which the cutter head, cutter drive and the suction pipe are mounted, is suspended by the pontoon and the laddergantry wire. Seagoing cutter suction dredgers have their own propulsion that is used only during mobilization. The propulsion is situated either on thecutter head side or on the spud poles side.

Areas of application

Cutter suction dredgers are largely used in the dredging of harbours and fairways as well as for land reclamation projects.The cutter suction dredger also has the advantage when an accurate profile has to be dredged. The cutter suction dredger can tackle almost all typesof 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 cuttinghead power ranges between 20 kW for the smallest to around 4,000 kW for the largest. The dredging depth is usually limited; the biggest suctiondredger can reach depths between 25 and 30 m. The minimum dredging depth is usually determined by the draught of the pontoon.

As said the cutter suction dredger is a stationary dredger with at least two side anchors that are necessary for the dredging process. Because of theseanchors they may obstruct shipping movements. Self propelled cutter suction dredgers uses their propulsion system no only during mobilisation butalso during shifting from one place to the other or when the dredging area has to be left, “breaking up” when bad weather is expected.

The small to medium sized cutter suction dredgers can be supplied in a demountable form. This makes them suitable for transport by road to inlandsites that are not accessible by water, for example to lay a sand foundation for a road or to dredge sand and gravel for the building industry.
