Marine Rubber Airbag

Florescence Ship Inflatable Marine Rubber Airbags is heavy-duty, inflatable marine equipment designed for vessel launching, haul-out, and salvage operations, complying with the international standard ISO 14409. We use good natural rubber material and unique vulcanization process ensuring wear resistance, airtightness, and high load-bearing capacity. 

Comparing to the traditional slipway launching method, the ship rubber airbags are much environmental, because rubber airbag can launch a ship at any seaside, so there's no need to worry about the construction of launching facilities; besides, the marine rubber airbag need little maintenance and can be used repeatedly(about 65-80 times,10 years).  Nowdays they have become a mainstream, cost-effective alternative to traditional slipways, especially for small-to-medium shipyards and complex operational sites.

Florescence Marine Rubber Airbag Advantages:

1.Dia1.5m airbag stock available, quick delivery.
2.Lifespan:can be re-used for 65-80 times,10 years 

3.Guaranteed period:24 months 

4.Certificates:CCS, BV,ISO, RS etc.

5.Provide repair kits.
6.Material:natural rubber, rubber-dipped nylon cord fabric
7.Factory with over 30 years' experience

8.Cost - Effective: Eliminates costly civil works for slipways/dry docks.

9.Flexible: Works on uneven terrain, in tight spaces, and adapts to various hull shapes.

10.Safe: Even load distribution minimizes hull stress; controlled movement reduces accident risks.

11.Eco - Friendly: Low carbon footprint vs. concrete slipway construction.

Material and Structure of Marine Rubber Airbags

Basic body consists of out rubber layers, synthetic-cord-reinforced rubber layers. It is kind of a cylindrical airbags with hemispherical heads at the both ends. All of these are vulcanized together, and then compress air inside to roll.

Prior to the airbag production, the outer and inner rubber layers shall be tested to meet criteria in the following table in accordance with the test methods given in the interational standard list in the table. While only one satisfactory sample per batch is required for test numbers 1 to 3, all others test numbers4 to 9 annually. If the first sample fails, two additional samples should be tested. If the additional sampies pass the test requirements, the materials will be deemed to have passed the test. Otherwise, the materials will be deemed to have failed the test and another batch of materials shall be selected.

Working Principle

Preparation: Position deflated airbags along the hull's keel path; deploy air compressors, winches, and pressure gauges.

Inflation: Gradually inflate to the calculated pressure to lift the hull evenly, reducing friction and avoiding structural stress.

Movement: The airbags roll or slide, enabling controlled vessel movement into water or ashore.

Recovery: Deflate and remove post - operation for reuse (average service life 6–8 years with proper care).

Accessories: Terminal iron, Pulling ring, Three-way connecting tube, Pressure gauge, Valve, Hose joint
