A cutter suction dredger, based on the rotation of the bucket and the mud treatment technology in the pump house, can remove silt and debris from water, restoring normal navigation.
Specifically, the bucket, mounted on the underside of the hull, rotates to suck silt and debris into it. Simultaneously, pumps in the pump house extract the mud from the bucket and deliver it to a storage area below the designated level or onto a transport vessel, thus achieving the purpose of clearing the waterway.
