Ship launching or landing technology has being seeing a great proliferation in development since 1981, when a 60 Discrete Wavelet Transform (DWT) tank barge with air bag suspension was launched in Jinan city of Shandong Province by Xiao Qinghe ship repair and building shipyard. The definition of air bag and its manufacturing process, utility factors has increased manifold. For every challenging marine mission, Marine Air Bags are completely apt. It is also cost effective in many ways. Most of the shipping corporations have admitted the beneficiaries of such air bags even for warfare purposes also.

Description of Marine Airbags:

Airbags with high performance and high usage technology needs to be procured with quality compositions. Generally there are three levels of fittings. These are 1) external rubber layer protecting the cord layers from scratch and other external injuries,2) synthetic- tire cord rubber layers for holding the pressure and spreading the stress uniformly as reinforcement strategy and 3) air tightness pivot and airbags safety air cove as end fittings.

Better ship launching system:

Where as in the initial year, rubber dipped canvas was used to form strengthening layer for air bags , its use was also  limited to small and flat bottom ships only and fabricated launching slope. However latest technical progress has upgraded its manifold use during emergencies. It also saves time, investment and land space. These are hassle free to use, maintain, clean and operate for the next use. The level of protection also gets revitalized. With Air bag one can redirect the ship or caisson by regulating internal pressure and manage the working height also. It does work against fierce sea wave as well.

Additional use

Use and productivity of air bags can be as versatile as marine applications are in reality. Apart from facilitating shipping movements, like ship launching, landing, floating docks and caisson launching these are also being used for heavy transport, marine salvage, heavy lifting and refloatation etc.

Scope of improvement for Air Bags:

To mention the limitations, side-launch of big ships is not possible with air bags till now. It needs more research and development to be done on design and landing process. Since now any type of ship with a Discrete Wavelet Transform (DWT) below 55,000 can be launched with the help of air bags. But to enable utilizing more spaces, air bags should be devised for DWT 100,000 ships.

Hence before selecting an Air bag supplier company there is some preconditions to follow:

• Presence of Highly innovative and latest technology used to over come the defects.
• Presence Single slide way resolution overcoming use of costly fixing slide way.
• Any fee for slide way construction
• Any need of infected oil
• Reuse facility of the air bags

Maritime consultancy is really important here to explore better application techniques and areas of improvement. Thus Marine rubber bag can be of great help for big transportation industries all over the world with technological modernization.
