There have been a lot of other first time airbag customers lately who are concerned about using the airbag to assist with launching.
In fact, according to different venues, facilities and ship conditions, there is no uniform process for airbag deployment, but in order to let customers know more about the use of our airbags, I have compiled a simple airbag deployment process for your reference, please understand
If you are a first-time airbag customer, don't worry. If you have any issues after your purchase, I will guide you and help you maintain your airbag to maximize its lifespan.
Feel free to chat with me if you have any questions or are interested in some of these steps.
The airbag launching technology is well-deserved as the “flexible launching technology” because of its high adaptability and many advantages. Now, we introduce the general procedure of ship launching with airbags. Ordinary ship launching can be simply divided into 6 steps.
Before launching, the vessel needs to be hold in position by a holding system. For the large ship, it is better to use ground anchors, winches, wire ropes, and pulleys. For the small ship, the shipyard can use a crawler crane to control for easier operation.
Insert the ship launching airbags between keel blocks. Then, inflating launching airbags to jack-up vessel. With the continuous expansion of the launching airbag, the entire hull is slowly supported by the airbag. Generally, the vessel will be lifted up from one end to another, step by step. Once vessel bottom leaves from support blocks, those blocks will be removed. At this time, the entire weight of the hull is distributed on multiple airbags. So created the conditions for dismantling the shipbuilding and laying aside the pier.
Treatment of site flatness, the flatness of the ground should be ensured as far as possible on the launching slope. If there are pits, they must be filled with bagged sand. If there are obvious protrusions, they should be flattened, and the bottom of the ship should be cleared and the ship passing by All the debris and obstacles that hinder the rolling of the ship launching airbags on all the fields.
That adjustment includes adjusting airbag pressure and vessel position. Sometimes vessel is built far away from the water. So have to move down on slipway before launching. Pressures of ship launching airbags need to be adjusted before the final launching according to practical conditions and the launching calculation.
Arrange mooring ropes on both sides of the ship. The ropes must meet the requirements of traction and must be introduced from the bow, tied to strong ground components such as bollards, and part or all of the hull can be tied if necessary. Remove all the piers under the ship, start the auto-release hooks, or cut the holding wire rope, and make the ship move into the water area with the help of the rolling rubber airbag. If the water area is limited, people can use the control launching, releasing winch ropes to let vessels roll down into water slowly.
The ship is successfully launched, drag the ship to the dock, and recover all rubber airbags, measure the ship’s bow and stern draft, and check whether there is any water leakage in each cabin.
