1. Marine airbags and salvage airbag are widely used in maritime salvage AIDS in floating, including the rescue of stranded ships or AIDS in floating and sinking ships and so on. Due to the unexpected and time-sensitive nature of maritime salvage projects, if the salvage company adopts conventional lifting methods, it is often subject to large lifting equipment or needs to spend high costs. By adopting the auxiliary technology of salvage airbag, the salvage company can complete the salvage work quickly and flexibly.
2. The overall salvage methods of large sunken ships mainly include buoy salvage and floating crane salvage. At present, the buoy used in the buoy method is almost rigid buoy of hard material. Rigid buoys have high lifting capacity and are easily affected by the underwater environment when they are submerged and tied to sunken ships. In addition, the buoys occupy large space and incur high storage and transportation costs.
3. Large floating cranes are the main tools for maritime salvage, but they are often limited by the lifting capacity of cranes and high transportation costs, which will lead to the increase of salvage costs.
4. The Marine salvage airbags made of flexible materials is flexible and multi-purpose, which can be folded or rolled into a cylinder for storage and transportation or diving, greatly improving the salvage ability of the salvage company. The salvage airbag can be inserted into the flooded cabin or fixed to the sunken ship deck, which has little force on the unit area of the hull and is beneficial to the safety of the hull. The influence of hydrological condition is relatively small when the salvage airbags dives, and the underwater operation efficiency is high.
5. Marine salvage airbag and Marine airbags can not only provide buoyancy for ship salvage, but also have great advantages in rescuing stranded ships. Through the launching airbags can be inserted into the bottom of the stranded ship, salvage airbag inflated can be jacked up the ship, in the action of dragging or after the thrust, the ship can be smoothly into the water.
1. Marine airbag launching is an innovative technology with independent intellectual property rights in China.
2. It overcomes traditional craft restrictions and is a promising new process for small and medium-sized shipyards.
3. Hoisting gasbag and scroll airbags are used to lift and transport ships safely into the water.
4. Qingdao beierte Marine airbag has developed a new type of high strength airbag, providing an effective guarantee for large ship launching technology. Ship launching airbags are available in low, medium, and high pressure options.

Remark: |
According to different launching requirements, different ship types and different ship weights, the slope ratio of berth is different, and the size of Marine airbag is different. If there are special requirements, can be customized. |
