Ship Launching Balloon / Ship Launching Airbags

NANHAI AIRBAG Specialize in Manufacturing Ship Launching Airbag, Marine Airbag, Inflatable Marine Airbag, Air-lift Ship Airbag, Marine Airbag for Ship Launching and Pulling, etc.

Ship Launching Airbags, also known as roller bags or ship launching balloon, are made of heavy-duty synthetic-tire-cord layers with inner and out rubber layers.


Rubber Ship Launching Balloons Application
 
Marine airbags are widely used for ship launching, heavy transportation and marine salvage nowadays. Marine airbags are often called ship launching airbags that indicate the most popular application of these heavy duty airbags is for ship launching. It is estimated that more than 80 percent new built ships who’s DWT below 60,000 are launched by marine airbags.

Major Strengths of Rubber Ship Launching Balloons

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.

Ship Launching Airbags Structure

The structure Nanhai No. 1 Marine airbag  for ship is shown in follow. It consists of a bag body and end-iron component. The bag body is made from vulcanization of base rubber and reinforced fiber material. The end-iron component is made of metal materials and connected to the bag body firmly.


 

The Selection of Ship Launching or Upgrading Airbags

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.
 

Length of Effective (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 Airbags (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.)
