Floating Dredge Hose is a critical component designed for offshore and port dredging operations, engineered to transport slurry, sand, and sediments efficiently across water surfaces. Manufactured using high-strength synthetic rubber combined with reinforced textile or steel wire layers, the hose provides excellent flexibility, buoyancy, and structural integrity.
The outer layer integrates closed-cell foam flotation, ensuring stable performance even under dynamic marine conditions. With superior abrasion resistance and high tensile strength, the hose is capable of handling heavy loads and high-pressure discharge while maintaining durability in harsh environments such as saltwater, UV exposure, and temperature fluctuations.
In a Southeast Asian port expansion project, a 20,000 DWT cutter suction dredger was deployed to deepen navigation channels from 8m to 14m. The project faced challenges including abrasive seabed material and strong tidal currents.
Hongruntong Floating Dredge Hoses were installed along a 1.5 km floating pipeline system. The hoses demonstrated excellent buoyancy stability, preventing pipeline submersion even under rough wave conditions. Their abrasion-resistant inner lining significantly reduced wear caused by high-density sand slurry.
As a result, the project achieved a 20% increase in dredging efficiency, reduced maintenance frequency by 30%, and ensured safe continuous operation. The client reported high satisfaction with durability and ease of installation, leading to repeat procurement.
