In large-scale marine and coastal engineering, power and capacity are critical. The 24 inch cutter suction dredger (CSD) is one of the most powerful classes of dredging vessels, capable of handling major offshore and reclamation projects with remarkable efficiency.
ITECH Co., Ltd., a professional dredging equipment manufacturer, supplies high-performance 24 inch cutter suction dredgers for sale designed to meet the demanding standards of offshore operations. Built for strength, endurance, and precision, these machines enable fast, continuous dredging even in challenging sea conditions.
A 24 inch cutter suction dredger is a large floating dredging system equipped with a rotating cutter head and a strong suction pump. The “24 inch” refers to the internal diameter of the suction pipeline, which defines its slurry transport capacity.
Compared to smaller dredgers, this model offers far greater dredging depth, discharge distance, and material throughput, making it ideal for offshore reclamation, port deepening, and mining operations.

| Main Dredge Pump | Heavy-duty centrifugal pump with high pressure and efficiency |
| Diesel Power Unit | 3,000–5,000 HP engines for pumping and cutting operations |
| Spud Carrier System | Stabilizes dredger during heavy-load dredging |
| Hydraulic Control System | Operates winches, ladder, and cutter head |
| PLC Control Cabin | Offers real-time operation monitoring and automation |
| Hull and Pontoon Structure | Reinforced steel body with anti-corrosion protection |
ITECH’s 24 inch dredger is available in both stationary and self-propelled models, depending on project scale and mobility requirements.
This dredger delivers production rates exceeding 10,000 m³ per hour, significantly reducing project duration and cost.
With ladder extensions, it can reach dredging depths of up to 35 meters, ideal for port and offshore development.
Equipped with high-powered pumps, it can transport dredged material up to 3,000 meters through floating pipelines.
The hull and spud systems are engineered for strong sea currents, ensuring stability and durability in offshore environments.
ITECH’s optimized hydraulic and pump systems deliver high performance while minimizing fuel consumption and wear.

A 24 inch cutter suction dredger for sale from ITECH can be deployed for multiple high-capacity operations, including:
Offshore Land Reclamation Projects – Creating artificial islands and expanding coastal infrastructure
Port and Harbor Construction – Deepening channels and maintaining navigable waterways
Marine Sand and Gravel Mining – Extracting seabed materials for construction aggregates
Environmental Restoration – Removing contaminated or unwanted sediment layers
Pipeline and Cable Laying Support – Preparing seabed trenches for subsea installations
Each dredger is engineered to perform consistently in varying seabed materials such as sand, clay, gravel, and silt.
Positioning and Anchoring – The dredger’s spuds and side winches stabilize it in the target area.
Cutter Head Activation – The cutter begins loosening the seabed or riverbed material.
Suction and Transport – The dredge pump draws the slurry into the suction line and pushes it through discharge pipelines.
Material Discharge – Sediments are deposited at reclamation or dumping sites.
Control Monitoring – Operators monitor pump speed, pressure, and depth from the control cabin.
ITECH dredgers feature a closed-loop hydraulic system and automated pressure sensors for safe and efficient operation.
ITECH’s 24 inch cutter suction dredgers are built for endurance and continuous heavy operation. The powerful cutter head can handle dense layers of compact clay and coarse sand with minimal downtime.
High-capacity pumps ensure that even at long discharge distances, the dredger maintains consistent flow and suction stability. The vessel’s modular pontoon design simplifies transportation and on-site assembly.
Daily: Check pump seals, hydraulic oil, and cutter head torque
