Ship Launching Balloon High Pressure Resistance Strong Airtightness Lightweight And Portable
Description
Inflatable marine airbags are engineered with multi-layer synthetic rubber and strong cord reinforcement, providing exceptional load-bearing capability and flexibility. They are widely used for ship launching, docking, and haul-out operations across shipyards and coastal industries.
( Case : In a shipyard in Turkey, a 2,000-ton cargo vessel required a cost-effective launching solution.
Traditional dry-docking was ruled out due to time constraints. The shipyard deployed 10 high-strength marine airbags along the keel. Within hours, the vessel was smoothly launched with no hull damage or delay. This operation saved the company over 40% compared to fixed launch systems. )

Features
High Load Capacity
Built with multiple layers of reinforced synthetic-tire-cord rubber, airbags can support vessels ranging from 100 to over 10,000 tons.
Excellent Elasticity and Flexibility
Superior elasticity allows airbags to adapt to uneven surfaces and maintain consistent load distribution during launch or haul-out.
High Safety Margin
Designed with a 4–6 times safety factor compared to working pressure, ensuring reliable performance under heavy loads.
Multi Layer Construction
Typically composed of 3–10 layers of rubber and fabric, providing extra strength and burst resistance.
Applications
Stern Launching in Remote Shipyards
In remote areas where infrastructure is limited, airbags enable stern-type vessel launching with minimal equipment and preparation.
Salvage of Fishing Boats in Harbors
When smaller vessels capsize or run aground near docks, marine airbags provide a quick recovery tool without heavy salvage cranes.
Oil Spill Barrier Deployment
Inflatable airbags can be used to help deploy or support floating barriers used in oil spill containment in ports or offshore.
