Large Marine Inflatable Airbags generate tremendous buoyancy through inflation, providing a safe, efficient, and cost-effective solution for launching, discharging, grounding, salvaging, and heavy object handling of ships. As an indispensable key equipment in the fields of shipbuilding and ocean engineering.
Our large marine inflatable is a versatile "sea strongman" from launch to rescue, made of high-strength synthetic rubber and multi-layer nylon cord, capable of withstanding the pressure of 100000 deadweight tons of ships, with a 24-hour air tightness loss of less than 3%. It is a "flexible heavy vehicle" for modern shipbuilding, port engineering, and marine rescue.
Our large marine inflatable airbags are the full chain guardians from the shipyard to the deep sea. The airbags we produce and manufacture, although born in China, have already gone global.
When the ship is launched, inflatable airbags are placed at the bottom of the hull to gradually inflate and lift the ten thousand ton giant ship into the sea. When the ship is deployed, it can also be operated in reverse to allow the hull to smoothly return to shore for maintenance or dismantling, especially suitable for remote ports without dry docks.
When transporting heavy objects, inflatable airbags can also transform into "offshore cranes", helping ports lift caissons, bridge components, and even entire offshore drilling platforms;
In ocean rescue, our inflatable airbags can also quickly inflate and straighten stranded or capsized ships.
The large marine restart airbags produced by the Aorunda factory have high cost-effectiveness, low investment costs, and low maintenance costs, making them an ideal choice for shipyards and engineering companies to control costs.
The airbag is packaged in a foldable plastic woven bag, which is small in size, light in weight, and convenient for long-distance transportation. It can be flexibly selected from sea freight, air freight, logistics, and other methods.
From raw material testing to finished product delivery, airbags undergo over 13 quality control processes to ensure that each batch of products meets standards and provides a 24-month quality assurance.
Aorunda's large marine inflatable airbags come in a wide variety of basic specifications. Their diameters span from 0.3 meters to 3 meters, effective lengths cover the range of 0.5 meters to 32 meters, and the number of layers can be customized to satisfy requirements of different tonnages and operating scenarios. What makes it advantageous is not just its three well-known major application fields, but also its excellent performance in extreme environments. Take certain products as an example: through material enhancement, they are capable of normal operation even in extremely cold conditions of -50℃, thus meeting special demands like polar scientific research. By adopting high-strength cords (e.g., dtex3 type), superior rubber formulas, and more advanced production techniques (such as integral winding), we have taken a leading position among other enterprises and realized overall superiority in load-bearing capacity, safety factor (which can reach 4.5 times), and service life.
When inflating, it is necessary to use a matching air compressor and strictly follow the symmetrical order from the stern to the bow, while closely observing the pressure gauge to avoid local overpressure causing bursting. After the airbag is inflated to the working pressure, a precise balance needs to be formed between the support provided by it, the frictional force experienced by the hull, and the gravity of the ship to ensure that the ship can glide smoothly and controllably.
After use, the airbag should be cleaned, dried, folded, and stored in a dry, cool, and ventilated environment. There should be no sharp or protruding hard objects on the surface in contact with the airbag to prevent puncturing the airbag body; Stay away from heat sources and chemicals to extend their lifespan.
