Product Introduction:

 

Ship Rubber Airbag is China independent intellectual property rights of innovative products, the products are mainly applied to ship launching and landing, weight lifting, handling, installation of underwater buoyancy aid etc. Nowadays, Marine rubber airbags are widely used in the world. The Products are less limited by space, no large mechanical equipment, can shorten the working period and save the unnecessary cost. Through years of development practice, marine rubber airbag is become more safety, effective and green environmental protection.

 

Over the past twenty years, the airbag ship launching system has made advancements in not only the airbag, but also the ship launching/landing technology. The first generation airbags used a rubber dipped canvas as a reinforcement layer to form the air chamber trunk. Two cone-shaped molds were then used to make the ends and everything was stuck together.

With today’s airbags, the whole-enlacing-technology used for manufacturing is done together. Rubber dipped synthetic-tyre-cords are used as the reinforcement layers with the trunk and two cone-shaped ends made at the same time. Everything is then-laced together, so the airbag doesn’t have any joints. Due to the development of rubber chemistry, the performance of the rubber employed in the latest airbags is highly enhanced and about 15 times that of the first generation bag with the same specifications.

The launching and landing technology has also developed. In the beginning, only small and flat bottom ships located on a fabricated slope could be launched with airbags. Now this technology is more flexible and less limited by the ship and landform. Now any type of ship with a DWT below 55,000 and in a place with enough launching space can be launched using airbags. The launching slope even can be sloped upward. It has really developed into a cutting edge technology for launching ships, and especially useful for some marine emergencies.

As a soft flexible body, airbag’s shape depends on various factors, such as the shape of ship bottom, ramp shape, width of ship bottom, length of airbag, position of airbag under the ship, etc.
Users should calculate the bearing capacity of airbags basing on above factors, correct bearing capacity accordingly.

 

Caculation of performance of airbags

Formula: Bearing capacity F=PS

P=pressure in the airbag(MPa)
S=contacting area between ship bottom and airbag(M²)

S= π*(D1-D2)/2

Instruction of Ship Rubber Airbags application in Ship Docking


1. Fasten the hull with the steel cable of traction winch.
 

2. Fill in one or several airbags in the optimum position of the prow bottom. After inflating, the prow shall be lifted to certain height so that the ship can be moved forward by the traction of winch. For ships with flat bottom such as barge and so on, the contacting are between airbags and the bottom is large, if the ship is light, the prow can be lifted by one airbag filled in from the prow. For ships which are difficult to feed in the airbags such as pontoon and so on, the airbags can be threaded from one side to another. If the ship is too heavy, add 1 to 2 or more airbags at certain interval until the prow can be lifted. As to power-driven ship with “V” shaped prow, the airbags must be moved to backward as the lift if not enough due to the small contacting area between the airbags and bottom of ship. Sometimes, the airbags must to be moved backward 1/4 of the length of ship to lift the prow. During being moved backward, precaution shall be taken to prevent scratching on the airbags by the stem. A “V” shaped groove can be dug firstly if possible so as to increase the contacting area between the airbags and the bottom. The coastal shipyard can bury the airbag in proper location during the low tide and pull the ship to where the airbags locate. Inflate the airbags and the ship will be lifted easily. Anyway, the shipyard may adopt applicable methods based on its own conditions.
 

3. Start the winch to move the ship. Feed the airbags gradually in accordance with the requirement of arrangement space until the ship is pulled to the slipway.
 

4. Lift ship with the help of crane, construct hard block, pad ship and remove the airbags.

 

Attention During Application
 

1. Working pressure must be controlled strictly, it is not allowed to exceed the working pressure.
 

2. No sharp and protruding hard object on the contacting surface of the airbags, to avoid the puncture on the skin of airbags.
 

3. Avoid the distortion along the length of airbag.
 

4. Empty inflating test must be performed if the airbags were not used for a long time or after reparation. The pressure should be as same as the testing pressure of our company. Inspectors must be at least 3 meters away from the airbags. For repaired airbag which was damaged in large scale, its working pressure should be lowered reasonably. Besides, annual check should be conducted on airbags which are used frequently.
 

5. Don’t drag the airbags on the ground.
