Large CSD400 16inch Ocean Gold Dredge Vessel
The large CSD400 16inch ocean gold dredge vessel is positioned on spuds and anchor winches to ensure the vessel is firmly anchored during dredging. The cutter ladder is lowered in the seabed. By pulling on the side wires, the cutter head is moved sideways, swinging around the main spud. By using winches and anchors, the dredger swings sideways and the cutter head cuts and removes the soil.

Product Description
1. Product Introduction
Large CSD400 16inch ocean gold dredge vessel is largely used in the dredging of harbours and fairways as well as for land reclamation projects. It has the ability to dredge nearly all kinds of soils – sand, clay, rock – and is used where the ground is too hard for trailing suction hopper dredgers. The ability to dredge stiff or hard material is dependent on the size and weight of the dredging equipment and the installed power of the cutter.

4. Product Details
Cutter Head
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, with a half dozen ‘toothed blades’, which vary in size and type depending on the material to be dredged.
