Product DescriptionBow Blowing Hose SetStructure and FunctionThe Bow Blowing Hoses Set is an important part of the bow blowing system on Trailing Suction Hopper Dredger(TSHD). Itincludes a set of flexible hoses connected with the bow blowing system on the TSHD and the floating pipeline. It is composed ofa head float, a buoyancy-free hose (Hose A), a tapered floating hose (Hose B) and mainline floating hoses (Hose C and Hose D),with the quick coupling, Bow Blowing Hose Set can quickly be connected to or disconnected from the bow blowing system.SpecificationApplicationsBow Blowing Hose Sets:Essential for marine vessel operations, these hose sets inject high-pressure air through bow thrusters to clear silt, seaweed, and debris from seawater intakes and sea chests. Critical in sediment-heavy harbors, tropical algae zones, and river estuaries where clogged filters risk engine failure. Their saltwater-resistant construction (reinforced rubber/steel braid) withstands corrosive ballast discharge, tank cleaning, and emergency bilge pumping. Vital for dredgers, offshore supply vessels, and tankers operating in clog-prone waters. Advanced models feature quick-release flanges for rapid deployment during tidal changes or urgent maintenance, ensuring continuous cooling system flow and compliance with SOLAS safety standards.Features(1) With high tensile strength.(2) Excellent flexibility, can bend to 360° in any direction.(3) It has sufficient buoyancy and can float in the water on its own.(4) There are obvious markings on the external surface of the Head Float for easy identification and safe operating.On new Trailing Suction Hopper Dredgers In China, the functions of the Head Float and the Buoyancy-free Hose are combinedby using a new half-floating hose as A Hose instead. In comparison, this solution reduces the manufacturing cost, but alsoreduces the bending performance of the Bow Blowing Hoses Set, and the hose set with a half-floating hose is not as soft andflexible as using a Head Float and a Buoyancy-free Hose combination.Best Bow Blowing Hose Set (for Trailing Suction Hopper Dredger) Manufacturer and Supplier | CDSRThis street light features high brightness, energy saving, environmental protection, and easy installation.

It maps the entire sediment transport route, starting with the Sinking Hose resting on the seabed for initial material intake, often near a cutter. Jet Water Hoses are strategically positioned to fluidize compacted sediments near the suction point. The critical transport path is formed by connected Section Hoses, comprising the main pipeline. Buoyancy is managed using Floats supporting sections requiring surface positioning. Tapered Floating Hoses facilitate smooth connections between pipes of differing diameters or at transition points. Where the seabed slopes significantly, Slope Adapted Hoses accommodate these contours without excessive stress. The majority of the surface pipeline often consists of Full Floating Hose sections, kept buoyant along their entire length. Approaching the discharge location, Discharge Hoses handle the final transport of the sediment-water mixture. Finally, Bow Blowing Hoses are specifically deployed for direct connection to barges or vessels, enabling precise sediment placement during discharge operations. The visualization clearly highlights how each hose type – from sinking intake to floating transport to specialized discharge – is optimally positioned to handle depth variations, seabed topography, buoyancy requirements, connection challenges, and the final placement of dredged material, ensuring efficient and effective sediment transfer throughout the system.Drawings & DimensionsDetailed CAD drawings and dimensional diagrams are available for download here or upon inquiry.
