Floating Dredge Hose is a precision-engineered marine pipeline designed to facilitate the safe, continuous, and efficient transport of slurry in dredging and offshore operations. Constructed with multi-layer synthetic rubber reinforced with high-tensile textile cords or steel wire spirals, it combines excellent mechanical strength, abrasion resistance, and flexibility.
The integrated closed-cell foam flotation system ensures reliable buoyancy, preventing the hose from sinking or misaligning even under dynamic water conditions, such as waves, tides, or strong currents.
The hose's inner lining is made from advanced wear-resistant rubber compounds specifically formulated to handle high-density slurry, including sand, gravel, and silt. This inner lining reduces friction, enhances flow efficiency, and prolongs service life by minimizing wear. The outer layer incorporates a UV- and ozone-resistant compound, providing protection against harsh environmental exposure.
A large offshore sand mining project in the Persian Gulf involved a 22,000 DWT trailing suction hopper dredger tasked with transporting high-density sand slurry over a 2.8-kilometer floating pipeline system. The operation faced extreme environmental challenges, including strong currents, high salinity, and peak ambient temperatures exceeding 45°C.
Hongruntong Floating Dredge Hoses were implemented to form a continuous discharge pipeline, providing consistent buoyancy and superior abrasion resistance. The hoses maintained alignment even under strong wave motion, while the reinforced structure sustained high-pressure pumping with minimal deformation.
As a result, operational efficiency increased by 27%, downtime was reduced by 40%, and maintenance frequency significantly decreased. The client reported enhanced safety conditions due to the hose's stability and leak-free operation.
