Evergreen Air-bags (Intense pneumatic tire) are widely used in ship launching and landing, sunken ships salvage and refloatation, heavy lifting and conveying. This is one great ship launching ways. 

Ship launching or upgrading depending on Evergreen floating Air-Bag is an innovative technology having utmost bright prospect in shipbuilding. Now the Flexible Launching Technology is full of mobility, with advantages such as saving effort, saving time, saving work load, saving investment, flexible, safe, reliable, and outstanding benefit, etc. The technology of apply air gasbag to the launching and landing of ships overcomes the restrictions of traditional slide board technology which is commonly used in building small or medium size ships. 

Evergreen floating air bag for upgrading and launching is an advanced technology with bright prospect which has got over the shortcoming of previous ship building factory's traditional technology and developed into a flexible upgrading and launching technology, with such advantages as labor saving, time saving, strength saving, investment saving, being flexible, sate, reliable and obvious economic benefit. 

Ship launching by Evergreen Floating Airbags is a highly innovative and promising technology. It overcomes the defects that small and medium shipyard capacities are limited by: the fixing slideway. Additionally, this technology also supplies another way for shipyards that do not have a fixing slideway.
