Cutter Head Suction Sea Sand Dredger

1.Hull Structural Modification for Better Stability
Add ballast tanks on both port and starboard sides.
Fill seawater during dredging to increase draft and lower gravity center, greatly reducing rolling.
Empty ballast water for road transportation.
Install fixed wave break coamings along gunwales and bow deflector plates to prevent green water on deck and wave impact on cutter ladder.
Thicken steel plates and add extra stiffeners on bow, hull side, ladder base and spud support.
Reinforce high-stress welds to avoid fatigue cracking under repeated wave vibration.
Mount detachable anti-roll buoyancy pontoons on two sides to widen transverse stability arm and suppress heavy rolling; pontoons can be removed for shallow-water operation and land transport.

2. Upgraded Mooring & Spud System to Reduce Drift
3. Shock Absorption Modification for Cutter Ladder Assembly
4. Weight Balance & Counterweight Optimization
5. Standard Operating Rules for Wave Mitigation
6. Auxiliary Anti-wave Supporting Measures
