Case Study: 14-Inch Jet Sand Dredging Ship Exported to Africa – Empowering Waterway Reconstruction
Project Background
A coastal country in East Africa faces severe sediment accumulation in its main inland river. Over a decade, the navigable depth has dropped from 5 meters to less than 2 meters, blocking cargo ships and stranding agricultural products like coffee and cotton from reaching ports. In early 2024, the local government launched a waterway reconstruction project and tendered globally for sand dredging equipment; Huayao Environmental’s 14-inch jet sand dredging ship was verified and selected as the core equipment.
Core Equipment Advantages (Adapted to African Working Conditions)
1. High-Efficiency Dredging: The 14-inch jet system quickly breaks up compacted sand layers, processing 800 cubic meters per hour – 40% more efficient than local equipment.
2. Environmental Adaptability: Equipped with anti-clogging sand suction pipes and drought-resistant power systems, it operates stably in shallow waters and high-temperature environments.
3. Low-Cost Operation & Maintenance: Modular design allows easy replacement parts to match local procurement channels, cutting long-term maintenance costs by 30%.
Project Outcomes
Three months after commissioning, it has dredged 15 km of key waterway sections, restoring navigable depth to 3.5 meters. Small and medium-sized cargo ships now pass unimpeded, and agricultural product transportation efficiency has increased by 50%. The local project leader commented: "Its efficiency and durability have laid the foundation for us to complete the waterway reconstruction ahead of schedule."
