If you’re going to be breaking up large seabed into rock and spoil, you’ll need a cutter suction dredger (CSDs). Have a look at our CSDs for sale.
Some CSDs are self-propelled, but most are towed into place. They’re then held in position using heavy pike-like structures called ‘spuds’ and anchors are deployed to stabilise the vessel during dredging.
A cutting head gouges the seabed into small chunks of rock and spoil which is then sucked through the connected cutter suction pipe. An ejector system moves debris through a floating pipeline to the shore or to barges for removal.
