Working Principle
The cutter suction dredger primarily accomplishes dredging tasks through the coordinated operation of
a cutter device and a dredge pump. The ladder frame at the bow extends below the water surface, where
the rotating cutter head—powered by a drive system—cuts and agitates underwater sediments, loosening
compacted soil, sand, or even rock layers. Simultaneously, the onboard dredge pump generates strong
suction pressure, drawing the loosened slurry through the suction pipe and transporting it via discharge
pipelines over distances ranging from hundreds to thousands of meters to designated areas, such as s
poil grounds or reclamation sites. This integrated process—excavation, transportation, and discharge—
is completed seamlessly without requiring additional vessels for intermediate transfers, significantly
enhancing operational efficiency.
