Ship Moving Rubber Roller Inflatable Air Bags For Launching And Docking

Ship Moving Rubber Roller Inflatable Air Bags For Launching And Docking

Ship and marine airbag is well known as ship launching airbag, marine airbag, rubber airbag, landing airbag, inflatable airbag, air balloon, rubber pontoon. It is composed by airbag body and terminal iron part. The airbag body is composed by natural rubber strength fiber material through vulcanization processing; The terminal iron part is made of cast iron, it is combined closely with the airbag body; One end is for pulling when moving the airbag, and the other is for charging and discharging the air.

Ship and marine airbag size range: Diameter is 0.6-2.8m, Length is 5-24m, layers usually from 3-10layers.

Ship and marine airbags are widely used in ship launching, landing , lifting and moving heavy goods, salvaging stranded boats. And are very popular with shipyard, ship owner, and marine supplies company now.

What are the other uses for this launching system?

Florescence marine airbag are not only used for ships, floating docks and caisson launching but they are also cutting edge for ship landing, heavy transport, marine salvage, etc. It is a versatile tool for many marine applications.

Application of Ship Launching Balloon

1. Ship launching, lifting and refloating

2. Floating bridge and dock construction

3. Rescue and remove of wrecked ship

4. Setting up temporary pontoon bridge pier and water transport channel

5. Blocking debacle of anti-flood and anti typhoon dam

6. Applying to short distance transport of the bridge, concrete piers, drilling equipment

Advantages of ship launching air bags
1.Less land form limited
Only need enough bearing power ground and no sharp objects
2.Minimum fixture needed
Need no more than air compressors,winches and steel ropes

3.Environment Protective
Do no harm to the environment. No chemical needed.
4.Time & money saving
Marine airbags are more cheap and portable than other methods.

Loading of airbags

The requirements of launching ship and relevant equipments.

1.Ship

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 pass 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.

3.Winch
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.

Features of ship landing airbag

1.Less land form limited
Only need enough bearing power ground and no sharp objects
2.Minimum fixture needed
Need no more than air compressors, winches and steel ropes
3.Environment Protective
Do no harm to the environment. No chemical needed.
4.Time & money saving
Marine airbags are much cheaper and portable than other methods.

Ship Landing Airbags Storage

1.The airbags should be maintained in a dry ventilated room and be protected from light.
2.The airbags should be in a relaxed condition free from tension, compression or other deformation.
3.The airbags should be kept away from any heat source.
4.The airbags should be protected from acids, alkalis, oils or organic solvents.
