HID Dredger describes a type of hydraulic dredger ,offers a variety of cutter suction dredgers to dredge compacted soils (sand, clay and rock) for reclamation, construction and other projects.

Regardless of size, all cutter suction dredgers are equipped with a rotating cutter head, which is able to cut hard soil or rock into fragments. The cutter head is a mechanical device, mounted in front of the suction head which rotates along the axis of the suction pipe. The working principle of the cutter suction dredger is that it disintegrates or breaks the cohesion of the soil to be dredged mechanically by this rotating cutter head.

 During the dredging works, a spud is lowered in the seabed to secure the vessel. As a result, it is kept on the same location, but by using winches and anchors, the dredger swings sideways and the cutter head cuts and removes the soil. 

Cutter suction dredgers come in a variety of sizes and types with a total installed power ranging from hundred kW on the smallest dredgers to some thousand kW for the largest. The dredging depth depends on the size of the dredger. Smaller ones can dredge in less than 2 metres depth.

HID cutter dredgers are non self-propelled allowing them to move from pulling by the tug boat.
