How does a suction dredger work?

Cutter Suction Dredger for maintaining and deepening waterways. How does a suction dredger work? Key Principles: The basics of a cutter suction dredger (CSD) are simple: it is a matter of loosening the soil, sucking it up, transporting it via pipelines and disposing it either at the disposal site or in a hopper barge. But in order for the dredger to dredge a certain area, different movements have to be made. This is where cuts, swings, strokes and steps come into play. The Process: Whilst dredging, CSD cutter suction dredger remain stationary by means of a spud that is lowered into the seabed. The dredger dredges by making a sideways swinging motion using anchors and winches. That way, very accurate dredging results can be achieved. The dredger moves forward by lowering the second spud – the so-called walking or auxiliary spud – for a short period, allowing the operator to reposition the working spud. CSDs are not designed to operate in swell conditions. The movements of the vessel may bend the spuds or damage the hinges of the ladder. Utilising central anchor systems (Christmas trees) instead of spuds can extend the workability in swell, but this affects the manoeuvrability and efficiency of the operation. Cutter suction dredger is easy to assemble and transport. It can be transported in bulk and assembled on the working site. The dredger comes with optional spud carriage and anchor boom, which makes it more versatile and efficient. The dredger's color can be customized to meet the customer's
