Cutter suction dredgers operate by swinging about a central working spud using moorings leading from the lower

end of the ladder to anchors. By pulling on alternate sides the dredger clears an arc of cut, and then moves forward

by pushing against the working spud using a spud carriage. A generally smooth bottom can be achieved, and modern

instrumentation allows profiles and side slopes to be dredged accurately. Some of the larger cutter suction dredgers are self-propelled to allow easy movement from site to site.

The size of a cutter suction dredger is measured by the diameter of the suction pipe and by the installed machinery power.

Pipe diameters are in the range 100 to 1500 mm. A modern highly automated cutter suction dredger is capable of achieving

high outputs over sustained periods and production rates of around 500000 m3/week are possible under good conditions.

Cutter suction dredgers can be used to deliver through a pipe- line or to load barges. They may also be used simply as loosening devices for material to be re-handled by another type of dredger, in which mode discharge is directly over the stern to the sea. Pipeline discharge is most

common but is vulnerable to waves and currents and causes an obstruction to other vessels. To avoid these problems part of

the pipeline may be submerged and laid on the channel-or sea-bed.

Cutter suction dredgers are mainly used for capital dredging, especially when reclamation is associated with the dredging.

Smaller vessels can be dismantled into sections and moved by road or rail for work in inland waterways, sludge lagoons,

reservoirs and similar isolated areas. Large heavyduty cutter dredgers are capable of dredging some types of rock which have

not been pre-treated.

An alternative form of loosening is the use of a rotating bucket wheel at

the suction mouth. Bucket wheel dredgers are most commonly

used in mineral dredging operations and to date have not found general

favour among the major international dredging contractors.
