Hongruntong Marine Inflatable Salvage Tubes are engineered for offshore construction, maintenance, and vessel stabilization applications. Manufactured from reinforced multi-layer PVC fabric, these tubes deliver exceptional strength, elasticity, and resistance to abrasion, UV exposure, and saltwater corrosion.
Designed to provide stable and controlled buoyancy, the tubes can be deployed individually or in groups to support vessels, floating platforms, and subsea modules during installation, maintenance, or temporary stabilization operations. Industrial-grade inflation valves with safety overpressure mechanisms enable precise buoyancy adjustment, allowing gradual lift while minimizing structural stress.
Lightweight, portable, and reusable, these salvage tubes offer cost-effective solutions for repeated offshore operations. They enhance operational safety, reduce reliance on cranes or tugs, and provide flexible support in dynamic marine environments.
During maintenance operations on a 2,200 DWT offshore supply vessel, deck equipment replacement required temporary stabilization to prevent vessel tilt from uneven weight distribution. Conventional lifting methods proved impractical due to wave motion and limited deck space.
Hongruntong Marine Inflatable Salvage Tubes were deployed beneath the hull along the vessel's sides. Incremental inflation distributed lift evenly, maintaining trim and stability throughout the procedure. The operation was completed safely with minimal crane dependency, significantly reducing operational costs and time.
Post-maintenance, the tubes were deflated, recovered, and stored for future offshore projects. The client reported improved safety, reduced equipment usage, and confirmed the tubes' suitability for redeployment in similar offshore operations.
