ISO14409 Standard Shipyard Buliding Ship Rubber Airbags
Product Introduction:
Marine 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, Ship 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.
The history of ship rubber airbags dates back to 1981. Xiao Qinghe ship repair and building shipyard, located in Jinan city of Shangdong Province, launched a 60 DWT tank barge with airbag suspension on January 20, 1981. Seven airbags were deployed in that project. One was 2 meters in diameter and 6 meters long and used for elevating. The remaining six airbags were 0.8 meters x 6 meters long and acted as the rollers. The first intention of that trial launch was to develop a prompt, less landform limited ship launching method for warfare purposes.
Comparing to the traditional slipway docking and launching method, the ship rubber airbags are much environmental, It's low cost and low risk. Unlike most other launching methods that are fixed infrastructures, ship docking airbag has relatively less limitations and can be used in versatile ways. It overcomes the disadvantage of fixed track docking in which capacity of shipbuilding and ship repairing is limited by the fixed infrastructures especially in small and medium-sized shipyards.Ship docking airbag can dock a ship at any seaside. Besides, the ship docking airbags need little maintenance and can be used repeatedly.The ship docking airbags provide support to the hull of the ship, its rolling motion take a vessel out of the water or launch into water. Thus it is obviously more safety than other options like sideways launching.

Storage of the Ship Rubber Airbags
1. If the airbags won’t be used for quite a long time, it shall be washed and dried, filled with talcum powder inside and coated with talcum powder outside, place it in dry, shady and ventilated place in the warehouse.
2. Place string the airbags should be far away from the heat source.
3. The temperature of the warehouse should be kept no more than 30℃.
4. Keep the airbags away from acid, alkali, grease and organic solvent.
5. The airbags should be stretched flat when not used. It is not allowed to pile up and stack heavy object on the airbag.
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.
Instruction of Application
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.
