Ship launching airbags, also known as marine airbags, inflatable boat airbags, roller bags, airlift bags and rescue bags, are made of heavy-duty synthetic tire cord layers with inner and outer rubber layers in the shape of a long cylindrical balloon. Ship launching airbags lift the limitations of traditional skateboard technology that is usually used to build small and medium-sized ships, and it provides an economical alternative to expensive dry docks. Its size can reach 2.5m in diameter and 25m in length, and can be used for hoisting and transporting heavy structures weighing more than 10000 tons.
The outer layer of the shipping launch airbags is made of rubber, which is designed to protect the inner rope layer from external forces such as abrasion. The material used for the outer layer is strong enough to withstand different weather and physical conditions. The synthetic reinforcement layer is similar to the reinforcement layer in tires. The cord layers are organized at specific angles so that the stress is evenly distributed to provide adequate reinforcement. Airbags also have end fittings, including safety air inlets and airtight rotary joints.
Airbags for ship launching and landing is an extremely promising mature technology, it overcomes restrictions of traditional methods, which are limited by the building and repairing capability of small ship factories, and developed into an extremely flexible technology, which has the advantage of labor-saving, time-saving, economical saving, flexible and a prominent economic benefit. Boomarine is a professional manufacturer and supplier of marine fenders, our airbags are widely used in ship launching or landing, heavy lifting and conveying, sunken ship salvage, and stranded ship saving.

1. Overpressure Control
The length and diameter of each vessel's launching bladder are measured at rated working pressure to within ±3%.
2. Appearance Inspection
The appearance of each of our marine launch bladders is smooth and shiny, free from imperfections such as cracks, blistering, delamination, pits or impurities.
3. Airtightness Inspection
Airtightness is tested according to ISO 14409 without carrying any load. The pressure loss within 1 hour is less than 5% of the rated working pressure.
3. Avoid Sharp Objects
When using it, make sure there are no sharp objects and make sure the ground is level and clean to prevent the airbag from bursting.
