Product Description

Why you should care our airbags:

Do you spend a lot of capital in increasing your shipbuilding or ship repair capacity without knowing that FLORESCENCE ISO14409:2011 Airbags can do the same with more versatility & lower costs?Conventionally, building Dry Docks, Cradles & Rollers are extremely expensive & time consuming. What's worse? The amount of ship repairing businesses you can take, is limited to the number and dimension of docks you have. However, businesses today should be agile and should possess highly versatile equipments to adapt to the ever-changing economy.

Ship launching or upgrading 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 airbag 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, even up to 60,000 DWT.


ship launch details

The requirements of launching and ship and relevant equipment:




The engineering work under water line shall wholly be finished, especially those equipments , valves and others that are to be installed at the openings under ship waterline,the installations should be approved by inspection. All the burrs, welding beading and the like on the ship bottom or appendages should be ground away. All the welds on the shell plate must pas inspection and tightness test. The main dimensions of the ship should be measured up and the mark of loadline must pass inspection. All the paint work of the shell plate has been finished.


2. Ramp way 


The ramp way on which the airbags will rolling should be cleaned and be clear of sharp fends such as iron nail. The ramp way should be leveled and the level error from left to right should less than 80mm. The ground caved in should be filled up and the ground bearing capacity should be relatively equalized. The ramp made of mud land, sanded land, sands or concrete, however, its bearing capacity should be twice as big as the working pressure of airbags. The slope of ramp is to be determined according to the size of the launching ship and is generally no bigger that 1/7. In the range of the whole length of the ramp way, the shape may be of multiple combination with slope line, are line and others. However, the ship bottom should not contact the ground even when the airbags are at their lowest working height. The ramp way should extend into water for certain length.




In general, a slow winch is to be selected, its veering speed is about 9-13/m/min. The moving speed of a ship must not be more than 6m/min with the control of hauling force of winch wire. If the ship weight is less than 200t, the moving speed can be increased properly. The wire must be inspected and replaced regularity.


4.Air compressor


The type and capacity of the air compressor is to be selected according to the total volume of all the airbags provided for the launching and time required for air filling and the air pressure. The gas tank of air compressor should be installed with adjustable pressure limiting valve


Our marine airbags' accessories:



Marine salvage airbags can be inserted between vessel bottom and seabed to lift sunk vessel 

which can partly restore buoyancy of vessel itself. In theory, the combination of our airbags can lift any ships, as long as the ship is not too deep under the water. For stranded vessel salvage this heavy lift 

function is extremely useful.To send a stranded ships back to water marine airbag is the most 

convenient tool. People can insert airbags to the bottom of vessel and then inflate them. With the pull of a tugboat or push of a bulldozer, ship can easily move into water with the roll of airbags.


How to use airbags to salvage ship: 


1.)what equipments are needed to install / securing / inflate the air bags(for salvage)?
You will need diver to go under the water(install); and tie our deflated airbags with rope or net to the 

bottom of your ship(securing); then inflate the airbag with air compression machine linked by rubber 

hose on the land.



2.)what is our warranty?


We cans assure that we can lift any ships as you wanted, as long as we get enough proper information of the project.


Besides the airbags, we can design suitable solution for your projects and provide any equipments that are need druring the salvage, including rope or rope net,  rubber pipe and air compression machine, etc


Our Services

 What we can do (Services supplied):

we offers total pack for launch and haul-out projects which include launch design, airbags supply, on site support

and worker training also we can provide launch or haul out service according to demand. After years of practice

and accumulation of experience,  we have developed this ship launching techniques from facilitating the launching

of only 1, 000 DWT ships to current 60, 000 DWT ships.  And now this launching technology has become into a

flexible,  promising, secure and mature technology.  Besides that, Florescence marine airbags are widely used in

launching and haul-out of vessels of all sizes.

How much space should be between two airbags ? also find the suitable quantity airbags will save you much cost.Below is some tips for your reference:

 In fact, the max. space of airbags should not exceed 6m,the minimum of the airbags is decided by airbags diameters.the follow chart shows the minimum space with different diameter airbags:


       Airbag diameter   1m 1.2m  1.5m  1.8m  2.0m
       Minimum space 1.5m 1.8m  2.2m  2.8m  3.0m
