The 500mm cutter suction dredger features a cutting mechanism at the suction inlet that loosens bed material for efficient transport. Equipped with a wear-resistant centrifugal pump, it effectively handles hard surface materials like gravel deposits or surface bedrock where standard suction dredgers would be ineffective.

• Cutter Head: Alloy cutters for breaking hard soil layers
• Suction Pipe: Creates negative pressure for mud-water mixture suction
• Dredge Pump: Powers mud transportation through discharge pipes
• Positioning System: Spuds or DP dynamic positioning for precise movement
• Ladder: Liftable structure supporting reamer and suction pipe

Excavation: Rotating cutter head cuts and crushes bottom materials at high speed.

Suction: Powerful mud pump generates vacuum to suck loosened material mixture.

Transport: Pressurized mud moves through internal pipe system.

Discharge: Material transported via pipeline to shore or loaded onto barges.

• Continuous high-efficiency operation
• Wide material compatibility from silt to medium-hard rock
• Long-distance material transport capability
• Precise depth and flatness control
• Reduced environmental impact compared to alternatives

• Port and waterway construction
• Land reclamation and island building
• Environmental remediation projects
• Subsea mineral mining operations
