Cutter suction dredgers are carrying out dredging projects in Benin, Africa

When using the cutter suction dredger produced by SCO HID Shipyard to carry out the dredging project in Benin, Africa, its high efficiency was highly praised by the project manager.

1. Technical advantages of SCO HID cutter suction dredgers:

SCO HID adopts a double-pair cutter head + variable frequency drive design, which is suitable for the common mixed substrate of sand and silt in Benin. The cutting efficiency is 20%-30% higher than that of the traditional single-pair cutter.

Intelligent sludge pump matching: Customize high-head sludge pumps based on the Benin project's discharge distance (3-5 kilometers) to reduce the demand for intermediate booster stations and lower energy consumption.

Automated control system: Integrating GPS positioning and dredging trajectory planning software (such as DredgePack), it achieves centimeter-level precision excavation and reduces repetitive operations.

2. Environmental adaptability design:

Modular structure: In response to the limitations of African port infrastructure, the hull can be disassembled for transportation and quickly assembled on site.

Corrosion-resistant coating: It can cope with the high salt spray and high-temperature environment in Benin, extending the service life of equipment (if epoxy zinc coating is used, the maintenance cycle can be extended to 5 years).

3. Innovation in construction mode:

24-hour continuous operation: Combined with mosquito-proof lighting and shift system, it breaks through the window restrictions during the rainy season (such as increasing the annual operation days to 300 days).

Collaborative operation: In coordination with small rake suction vessels, the cutter suction vessel mainly focuses on channel excavation, while the rake suction vessel cleans the corner areas, increasing the overall efficiency by 40%.

The efficient performance of the SCO HID cutter suction vessel stems from the combination of multiple aspects. In the future, the social and economic benefits of the project can be further enhanced through green energy transformation and community collaboration.

The dredging project in Benin, Africa, is another proud milestone for COHIDShipyard. We will continue to support global waterway development with reliable and cost-effective solutions.
