Dredging ships are widely used in dredging projects and are a type of hydraulic suction dredger that is extensively applied. They utilize devices equipped around the water intake pipe to cut and stir the sediments and minerals on the riverbed, allowing the mud and sand to mix thoroughly with water to form a suspended solid-liquid two-phase flow that can be transported hydraulically. Then, through the mud suction pipe, the dredged mud and sand mixture is transported to the disposal site of the material with the help of a powerful pump. The processes of dredging, suctioning, transporting, and discharging can be completed continuously in one go, making it an efficient and cost-effective dredging ship, and an excellent underwater excavation machine.
