Description
Hongruntong Marine Inflatable Salvage Tubes are rapid-deployment buoyancy solutions designed for emergency rescue, accident response, and temporary vessel stabilization. Constructed from reinforced multi-layer PVC fabric, they provide high tensile strength, durability, and resistance to saltwater, abrasion, and UV exposure.
These tubes deliver controlled lift and stability to flooded, grounded, or damaged vessels, helping prevent capsizing or further structural compromise. Industrial-grade inflation valves with safety pressure release ensure gradual and adjustable buoyancy, allowing safe stabilization even in urgent situations. Lightweight and portable, the tubes are ideal for rapid deployment by rescue teams, salvage operators, or port authorities.
Designed for repeated use, the tubes offer a cost-effective solution for emergency operations, providing reliable performance under challenging marine conditions.
Case Study – Stabilization of a Flooded Fishing Vessel
A 450 GT fishing vessel collided with a submerged object near a coastal bay, causing hull breach and rapid flooding. Immediate stabilization was critical to prevent capsizing and ensure crew safety. Conventional lifting equipment was not readily available, requiring a fast, deployable solution.
Hongruntong Marine Inflatable Salvage Tubes were transported and positioned along the vessel’s hull. Sequential inflation allowed gradual lift, stabilizing the vessel’s trim and preventing further water ingress. The operation enabled safe crew evacuation and temporary patching of the hull.
Within two hours, the vessel was secured, and the tubes were recovered for future use. The rescue team reported significant time savings, reduced operational risk, and reliable performance under emergency conditions. This case demonstrates the tubes’ effectiveness in urgent situations, providing rapid, repeatable, and safe buoyancy support.

Features
Compact and Modular Design for Confined Spaces
The cylindrical tubes can be configured in multiples, allowing flexible placement along hulls and shallow-draft vessels. Their compact deflated state facilitates storage and transport within port facilities.
Durable Multi Layer Fabric for Frequent Deployment
High-quality PVC-reinforced fabric provides resistance against abrasion from docks, rocks, and other submerged obstacles. Tubes are engineered to maintain airtight integrity over repeated deployments.
Precision Buoyancy Control
Industrial-grade inflation and overpressure valves allow operators to carefully regulate buoyancy. Gradual lift prevents sudden movement, reducing operational risk in confined waterways.
Cost Efficient Reusable System
Designed for repeated use in daily port operations, the tubes reduce dependency on heavy cranes and tugs, lowering operational costs while maintaining operational safety.
Applications
Barge and Workboat Refloating
Ideal for ungrounding barges and small vessels in shallow harbor areas with minimal structural risk.
Temporary Buoyancy for Docking and Maintenance
Supports vessel trim adjustment during inspections, hull cleaning, or minor repairs in port facilities.
Emergency Response in Ports
Rapid deployment during accidental groundings or flooding incidents to prevent delays and congestion in busy channels.
Advantages
Specialization in Port and Inland Waterway Operations
Design and engineering tailored for confined spaces, shallow waters, and tidal variations.
Flexible Customization for Vessel Types
Buoyancy, dimensions, and modular configuration can be adapted to barge, ferry, or workboat requirements.
High Quality Materials and Testing Standards
All tubes undergo strict inspection for seam integrity, valve performance, and airtightness to ensure reliability under repeated use.
Operational and After Sales Support
Technical guidance and deployment recommendations provided to port authorities for safe, efficient operations.
FAQ
1. Can these tubes be used in shallow ports and canals?
Yes, the cylindrical design allows effective deployment in shallow waterways with limited clearance.
2. What are typical deployment times?
