The use of marine airbags to launch a ship and to land it back in a dock is a very novel process. The concept was developed in the year 1981 in the Jinan province of China. In these past thirty years, this concept has undergone a lot of development and revolution and is now one of the most recognised methods of launching and landing a ship.
Salvage Rubber Airbag is made of rubber material, which is different from the metal material another salvage equipment. It can produce water buoyancy, the overall sealed, submerged in water can bring huge buoyancy, So it is mainly used for salvage sunken Vessels, weight lifting and moving and some other emergency rescue projects etc.
Through filling the compressed air to produce buoyancy, then using
buoyancy to salvage, easy operation and safe and reliable.
In addition to hang a vessel in a fixed position or connected with
lifting jack of the bottom of Vessel, Marine Rubber Airbags also
can be placed inside the Vessel cabin, through filling out the
cabin water to provide buoyancy.
The use of airbags helps to remove the hindrance of using tows and tugs as launching and landing instruments. Moreover since the airbags use synthetic rubber and a high defined system as their core design, it has become easy to use such airbags for any ship that has a DWT (Dead Weight Tonnage) of less than 55,000.
Airbag Size:
Another most important advantage of using an airbag for the purpose
of launching ships is that the process is re-doable. The airbags
after they have served the purpose of either launching a ship or
landing a ship in a dock can be pressed out of the inflating gas and then folded for using
them again at some future date. This ensures that there is no extra
financial burden involved unlike when the more traditional methods
of ship launching and shoring are used.Additionally, the revolution carried out in the process of using
airbags as launching tools also has the advantage of being used for
any kind of ship. This factor is very important because in the
initial days when the marine airbags were newly launched in the
shipping industry.
