Ship Launching Airbag High Strength Durable Easy Deployment
Product Overview
Marine Rubber Airbags are reinforced inflatable marine handling devices engineered for ship launching, vessel landing, hull shifting, temporary support, and controlled load transfer operations in shipyards and marine construction environments. The product is designed to provide a flexible load-bearing interface between a vessel hull and the supporting ground, allowing substantial vessel loads to be transferred through controlled internal air pressure rather than through fixed mechanical structures.
This operating principle makes Marine Rubber Airbags suitable for shipyards and marine contractors that require adaptable vessel-handling equipment for projects where permanent slipways, dry docks, or heavy lifting systems are limited.
Case Study: 3,600 Ton General Cargo Vessel Launching in Turkey
A coastal shipyard in western Turkey successfully launched a 3,600 ton general cargo vessel using Marine Rubber Airbags. The vessel was fabricated on a reinforced shore-side construction area approximately 20 meters from available water access. The shipyard lacked conventional fixed slipway infrastructure suitable for the completed vessel.
Marine Rubber Airbags were selected after reviewing vessel weight, hull dimensions, available launching distance, surface condition, and required support capacity. The airbags were positioned beneath the hull according to planned support spacing, with inflation performed progressively while monitoring vessel support conditions.
The vessel reached the water access area without structural damage to the hull or airbag system. The operation demonstrated the importance of coordinated pressure control, support spacing, surface preparation, and continuous monitoring when using inflatable load-transfer equipment for large marine structures.

Key Features
High Strength Multi Layer Reinforcement Structure: The primary load-bearing component features multi-layer reinforcement with high-strength synthetic tire cord embedded between rubber layers, creating a composite structure capable of resisting tensile forces generated by internal air pressure.
Pressure Controlled Load Transfer: Uses controlled internal air pressure to generate supporting force beneath vessels, allowing support capacity to be adjusted within the specified working range for controlled transitions from fixed supports to inflatable supports.
Wear Resistant Rubber and Environmental Adaptability: Outer rubber layer provides resistance to abrasion and mechanical wear while maintaining flexibility and tolerating common marine environmental conditions including moisture, saltwater exposure, and humidity.
Reusable Structure for Repeated Marine Operations: Designed to be deflated and redeployed for multiple marine handling operations, providing particular value for shipyards and contractors handling multiple vessels over extended operating periods.
Applications
Ship Launching and Vessel Landing: Transferring newly constructed or repaired vessels between shore-based construction areas and water access points for cargo vessels, fishing vessels, workboats, barges, pontoons, and other vessel types.
Shipyard Vessel Shifting and Relocation: Providing temporary rolling support for relocating vessels between fabrication zones, maintenance areas, assembly platforms, and launching positions where conventional heavy transport systems are unavailable or inefficient.
Temporary Hull Support During Marine Repair: Creating access to areas that would otherwise remain below the waterline during repair, inspection, coating, and maintenance operations while reducing reliance on isolated lifting points.
Why Choose Hongruntong Marine
Established Marine Manufacturing Capability: Over 30 years of manufacturing experience in marine rubber products and ship-handling equipment, with production processes organized around industrial marine equipment requirements.

Material and Process Quality Control: Application of production controls to maintain consistency during material preparation and assembly, with finished products subject to dimensional, appearance, and pressure-related testing.
Technical Support for Project Deployment: Provision of technical product information covering installation considerations, handling procedures, maintenance requirements, and project coordination documentation.
Frequently Asked Questions
How are Marine Rubber Airbags sized for a vessel launching project? Sizing is based on vessel weight, hull dimensions, airbag diameter, effective length, operating pressure, contact condition, and required support arrangement. The total number of airbags is determined through engineering calculation considering actual vessel load and required operational safety margin.
What working surfaces are suitable for Marine Rubber Airbags? Suitable surfaces include properly prepared concrete, compacted soil, sand-based launching areas, and other stable surfaces. Sharp stones, exposed reinforcement, steel edges, broken concrete, and other concentrated hazards must be removed before deployment.
How frequently should the airbags be inspected? Visual inspection should be conducted before and after each major operation, covering rubber surface, seams, reinforcement-related deformation, end fittings, valves, and any signs of leakage or abnormal wear.
Can Marine Rubber Airbags be supplied with customized dimensions? Yes. Diameter, effective length, overall length, reinforcement configuration, working pressure, and end fitting arrangements can be customized according to project requirements.
What documentation should be requested for an industrial project? Documentation may include product specifications, material information, inspection records, pressure test information, operating instructions, and other manufacturing or quality documents.
