AI Technical Summary
Traditional cutter suction dredgers require frequent replacement of positioning piles during dredging operations, which affects the continuity and efficiency of dredging work.
A traveling frame and wheels are installed at the bottom of the cutter suction dredger. The traveling wheels are driven by a drive unit to move on the seabed. Combined with a water jet propulsion system, a stable driving force is provided to achieve continuous dredging operations.
It improves the continuity and efficiency of the cutter suction dredger, ensures the stable movement and adaptability of the hull, reduces interruptions caused by the replacement of positioning piles, and improves the overall efficiency of dredging operations.
