Ship Launching Airbags Shock Absorption Strong Resilience Stable Support
Product Description

Marine Rubber Airbags are an innovative, portable, and reliable solution for launching, lifting, and transporting ships and heavy marine structures. Unlike dry docks or rail-based launching systems, they require no permanent infrastructure and can be deployed almost anywhere with minimal preparation. This makes them a cost-effective option for small to large shipyards, offshore projects, and emergency salvage operations.

Each airbag is constructed from multi-layer natural rubber and synthetic cord fabric, designed to withstand high working pressures, repeated rolling, and heavy dynamic loads. Their elasticity and high friction coefficient provide controlled movement of vessels during launching or hauling, while their cylindrical design ensures even force distribution and safe support.

Case Study
In 2022, a ship repair yard in Turkey used 18 Marine Rubber Airbags to haul a 7,000-ton passenger vessel onto shore for maintenance. The operation required minimal site preparation--only compacted soil and anti-slip mats beneath the airbags. Over the course of six hours, the vessel was carefully rolled onto land without hull damage. Compared with traditional dry dock docking, this method reduced operational costs by nearly 40% and avoided weeks of downtime. The successful operation proved the effectiveness of Marine Rubber Airbags as a flexible and reliable alternative to fixed facilities.

Marine Rubber Airbags are now widely recognized as a breakthrough technology in ship launching, salvage, and heavy marine engineering. They enable projects that were once considered cost-prohibitive or logistically complex to be carried out safely, efficiently, and with greater flexibility.

Features
  • Exceptional Load Bearing Capacity: Marine Rubber Airbags are designed to handle enormous loads, from small 500-ton vessels to 20,000-ton or larger ships. The layered rubber-and-cord construction provides high tensile strength, ensuring that the airbags maintain structural integrity under extreme working pressures.
  • Long Term Durability and Weather Resistance: The outer rubber layers are engineered for abrasion resistance, ozone resistance, and UV stability. Marine environments often involve saltwater, temperature fluctuations, and sharp debris, yet the airbags maintain their performance and integrity.
  • Rapid Deployment and High Portability: Compared with constructing slipways or renting floating docks, Marine Rubber Airbags can be deployed quickly with minimal setup. They are lightweight, rollable, and transportable by truck or container.
  • Built In Safety and Shock Absorption: The elasticity of the airbags allows them to absorb shocks during launching, preventing damage to vessel hulls and reducing stress on ground infrastructure.
Applications
  • Ship Launching and Landing: Perfect for both new ship launches and pulling vessels ashore for repairs. They are suitable for fishing boats, ferries, cargo ships, and offshore platforms.
  • Heavy Lifting and Relocation: Used to lift, move, or position heavy industrial structures, floating docks, and large marine components onshore or offshore.
  • Emergency Salvage: Provide buoyancy to refloat sunken vessels or stabilize damaged ships. Their quick deployment makes them invaluable in urgent salvage scenarios.
  • Pipeline and Offshore Support: Assist in transporting and installing subsea pipelines or structures. Their durability and buoyancy control allow them to handle complex offshore tasks with precision.

FAQ
1. What sizes are available?
Marine Rubber Airbags are available in diameters from 0.8m to 2.5m and lengths from 5m to 24m. Customers can choose based on vessel size and project requirements.
2. How are airbags used for launching?
Place the deflated airbags evenly under the vessel hull, then gradually inflate them to lift the ship. Once the vessel is afloat, airbags can be rolled away for reuse. This process is faster and more cost-effective than traditional slipways.
3. What is the service life of the airbags?
With proper maintenance, airbags typically last 8-12 years. Maintenance includes rinsing with fresh water after use, inspecting seams and valves, and storing them deflated in a cool, dry place.
4. Are they safe for large vessels?
Yes. Our airbags are designed to safely handle vessels over 20,000 tons when used in groups. Overpressure relief valves and reinforced layers ensure predictable performance and safe operation even in heavy-duty applications.
