Hose Floats are engineered flotation devices specifically developed to support dredging pipelines and floating slurry transport systems operating in coastal reclamation projects, port expansion works, river dredging operations, and marine infrastructure construction. The primary function is to provide controlled buoyancy for dredge hoses while maintaining pipeline alignment, operational stability, and efficient material transportation under dynamic working conditions.

The product consists of a high-buoyancy closed-cell foam core protected by a heavy-duty polyethylene shell manufactured through rotational molding technology. This construction combines lightweight flotation performance with exceptional resistance to impact, abrasion, ultraviolet radiation, seawater exposure, and harsh marine operating environments.

A major port expansion project in Southeast Asia required transportation of over 18 million cubic meters of dredged material across five kilometers. The project faced challenges with pipeline instability, uneven flotation, and accelerated hose wear due to strong tidal currents and vessel traffic.

Following engineering assessment, a customized Hose Float solution was implemented. The modular split-body design enabled rapid installation without pipeline disassembly. Within six months, the contractor reported measurable improvements in dredging efficiency, pipeline stability, and reduced maintenance requirements.

• Good flexibility, excellent impact resistance, particularly suitable for construction in open sea
• Lightweight design for easy installation and handling, low transportation costs
• High corrosive resistance, 3 times longer life than steel floats
• Higher cost performance than steel float alternatives

Custom float configurations are available upon request.

Manufactured with heavy-duty polyethylene shells engineered to withstand demanding dredging environments. The rotational molding process creates a seamless structure with uniform wall thickness, reducing stress concentrations and improving impact resistance.

Internal flotation medium consists of high-density closed-cell foam designed to deliver reliable buoyancy under long-term marine exposure. The closed-cell structure prevents water ingress and maintains stable buoyancy characteristics throughout the operational lifecycle.

Engineered to create controlled buoyancy distribution along floating pipelines, helping maintain alignment and reducing excessive movement caused by waves, currents, and equipment operation.

Split-body construction enables installation around existing hose systems without disconnecting pipeline sections. Modular design facilitates transportation, storage, and deployment across large project sites.

Hose Floats can be manufactured for a wide range of dredging hose diameters. Custom internal dimensions and fastening arrangements can be developed to accommodate project-specific hose configurations.

Yes. The outer shell is designed to withstand demanding dredging environments involving abrasive materials, mechanical impacts, and continuous marine exposure.

Calculations consider hose weight, slurry density, pipeline diameter, water depth, environmental conditions, and desired pipeline geometry to determine the required flotation capacity.

Yes. The modular split-body design allows individual float units to be removed and replaced without disassembling the entire pipeline system.

Service life depends on operating conditions, environmental exposure, handling practices, and maintenance procedures. Under normal dredging conditions, properly engineered Hose Floats provide long-term buoyancy performance and structural reliability.
