Inflatable Marine Airbag
1.High safety level: equipped with a reliable safety valve, our airbags can stand the maximum pressure up to 4 times that of the operating pressure.
2.Good air tightness: pressure decreases less than 10% for a period of 24 hours.
3.Long lifespan: it is guaranteed that our airbags can sustain their designed operating pressure for 3 years.
4.A complete set of solutions is available.
The Selection of:
Diameter : General speaking, the diameter of airbags for ship used is Dia1.5m. If the piers' height is a little higher, we could choose the larger diameter airbags, such like Dia1.8m or Dia2.0m; and for the Dia1.0m or Dia1.2m airbags are suitable for some smaller sized ships.
LengthEffective (Le): The Le of airbags is the length of airbag's cylinder part, and does not include the length of head vertebral body.
(1) Ship width≤20m: In theoretical, Le of airbags= Ship width (B); and if the length of airbags could not feet the ship width, airbags could be put under ships for two rows.
(2) Ship width>20m: Generally speaking, airbags will be put under ship as two rows, as butt arrangement or cross arrangement. Operating Pressure of Airbags: Less than DWT 1,000 could choose S1 Category Airbags; Larger than DWT 1,000 could choose S2 Category Airbags; S3 Category Airbags are used for the special higher working pressure requirement situation.
NO.s of (N): The numbers of airbags required is decided by the length of ships/vessels, and N is equal to the NO.s of putting under ship body (N1) plus the spare ones (N2), which is formula: N1+N2=N (N1 stands for the pieces under ships, N2 stands for the pieces of spares). The main factors to decide numbers of airbags required is ship DWT and category of airbags. (NOTE: N1=DWT / (Bearing Capacity of Unit for airbags×Le), spare airbags are decided by the fact situation.)

FAQ about Ship Launching Airbags:
Q: "Can I use the ship's landing airbag for ship launching and docking?"
A: Ok. Our ship landing rubber ballons are widely used for ship launch/lift/move and salvage.
Q: "What are the advantages of your ship's landing airbag compared to the slipway?"
A: 1) Our ship landing rubber airbag is much cheaper than the slipway, but it can be reused, it can save money and labor.
2) Our ship landing airbags are inflatable, which saves time and is more flexible
3) Our boat inflatable marine airbags are much softer than the slipway and do not cause any damage to the bottom of the ship.
Q: "I have a boat, but I don't know how to choose the size of the ship's rubber airbag. Can you help me?"
A: Don't worry. We have more than 20 years of experience. Please tell me the information about your boat and we can suggest the right size for you.
Q: "I want to try your docking airbag, but I never use it and don't know how to use it. Can you help me?"
A: Of course. We will send instructions along with our ship landing airbags. We also have videos. We can teach you to use the on-site landing air bag.
Q: "What is the service life of your landing rubber airbag?
A: Our ship landing airbags have a design life of 6 to 8 years.
Q: "What kind of certificate can you provide for a landing airbag?"
A: CCS, BV, ABS, ISO certificates are available.
