Introduction
Marine airbags, also referred to as ship lifting/salvage airbags or inflatable pontoons, are flexible rubber devices used for maritime operations. They are commonly employed for ship launching, cargo handling, vessel relocation, and salvage operations, particularly in lifting submerged ships or heavy objects. These airbags serve as temporary buoyancy aids and load-bearing tools in marine engineering applications.
Construction
1) Outer Rubber Layer
A durable rubber exterior protects marine airbags from abrasion and external damage, featuring high tensile and tear resistance to endure harsh conditions.
2) Synthetic Tire Cord Reinforcement
Reinforced with synthetic tire cord (common in tires), layers are strategically angled to evenly distribute internal pressure and stress, delivering robust structural support.
Specifications
How to choose?
Before to provide suitable airbag size and quantity for your ship, please provide below information:
1.Vessel dimensions (Length/Beam/Displacement)
2.Surface type of the construction area (Soil/Reinforced concrete/Other)
3.Vessel classification/category
4.Initial water depth at launch position (in meters)
5.Slipway inclination angle (Measured on land surface)
6.Tidal variation schedule (High/Low tide timings)
7.Support structure elevation beneath hull (Block stand height)
8.Propeller submergence depth from water surface
9.Dry dock-to-water transition distance (Stern to launch point)
