Product Description
Inflatable Marine Airbags
Inflatable Marine Airbags are flexible pressure-bearing equipment developed for vessel launching, hauling, shifting, landing, and temporary marine support operations. The product consists of a reinforced rubber body, internal high-strength synthetic cord layers, end fittings, and an inflation system.
Case Study: 3,600-Ton Cargo Vessel Launching
A shipbuilding contractor in South Asia successfully launched a 3,600-ton cargo vessel using our marine airbags. The vessel was constructed onshore at a coastal fabrication facility that lacked permanent dry dock or conventional launching systems.
Hongruntong Marine provided specially configured airbags that were positioned beneath the vessel according to calculated load distribution. The system allowed controlled movement across prepared surfaces, with continuous monitoring and airbag repositioning throughout the operation.

Key Features
  • Optimized Rubber and Reinforcement System: Multiple layers of high-strength synthetic tire cord provide tensile strength while maintaining flexibility for deformation under load.
  • Controlled Load Distribution: Creates effective contact zones beneath the hull to distribute vessel weight across multiple flexible support points.
  • Resistance to Mechanical Wear: Outer rubber layer designed to withstand operational abrasion, compression, and repeated loading cycles.
  • Adaptable Dimensions: Available in various diameters and lengths to accommodate different vessel sizes and project requirements.
Applications
  • Launching newly built vessels from onshore construction sites
  • Ship repair and maintenance operations requiring vessel relocation
  • Marine construction and temporary vessel positioning
  • Bridge construction and repair operations
  • Marine salvaging and wreck removal
  • Heavy machinery and equipment transportation on water
Why Choose Hongruntong Marine
  • 30+ Years Manufacturing Experience: Established production foundation for reinforced rubber equipment in demanding marine environments.
  • Technical Selection Based on Actual Conditions: Custom configurations based on vessel weight, dimensions, and project requirements.
  • Comprehensive Quality Control: Manufacturing controls at all production stages including reinforcement assembly, bonding, and vulcanization.
  • International Project Support: Experience with international transportation, technical documentation, and coordinated delivery schedules.
Frequently Asked Questions
  • What is the main operating principle?
    The airbag uses controlled internal air pressure to create a flexible load-bearing structure that distributes vessel weight across multiple support points during movement.
  • Can airbags operate on concrete surfaces?
    Yes, on properly prepared concrete surfaces free from sharp edges, exposed reinforcement, and other hazards.
  • How does working pressure affect performance?
    Working pressure influences supporting conditions and deformation under load. Appropriate pressure is established based on airbag specification and vessel conditions.
  • How should used airbags be maintained?
    After operation, airbags should be deflated, cleaned, dried, and inspected for damage before proper storage.
  • Can you manufacture custom airbags?
    Yes, we can configure products according to specific vessel weight, dimensions, operating environment, and project parameters.
