Ship Launching Airbags
Ship Launching Airbags are also referred to Marine Airbags, which is a ship operation equipment made of high-strength rubber and synthetic fiber, featuring a reinforced layer of fabric and wear-resistant rubber structure. It includes an inflation valve and a tow-end assembly, generating buoyancy to support the ship’s weight through inflation. Its production complies with the JT/T 302-1996 “Technical Specification for Marine Airbags,” and has obtained international certifications such as from China Classification Society and French Bureau Veritas. It is primarily used in scenarios like ship launching, caisson transportation, and heavy cargo handling, capable of withstanding the launching pressure of vessels with a deadweight tonnage of 100,000 tons. The burst pressure exceeds industry standards, and the air tightness pressure loss is less than 3% within 24 hours.
Marine Airbags
What is bearing capacity of air bag?
It is maximum load carrying capacity of the air bag, while it suffers no permanent deformation or damage
What is body of air bag?
It is cylindrical part of the air bag after being fully inflated with compressed air
What is burst pressure?
It is internal pressure at which the air bag bursts
What is diameters of air bag?
It is diameter of the air bag body
What is head of air bag?
It is conical parts connecting the body and the mouth of the air bag
What is initial internal pressure?
It is air pressure that fully inflates the air bag, before compression
What is length of air bag?
It is lenght of the air bag body
What is mouth of air bag?
It is metal valves mounted on both ends of the air bag for charging air
What is percentage of deformation?
It is ratio of the deformed height to the original diameter of the air bag while the air bag is being compresssed
Ship Launching Marine Airbags
P= (D-H)/D
Where
P is the percentage deformation(%)
is the original diameter of the air bag (%)
H is the height of the compressed air bag (m)
What is rated working pressure?
It is maximum allowable internal pressure of the air bag while supporting a weight or load equal to the rated bearing capacity of the air bag
What is Synthetic-tire-cord layers?
It is reinforced layer of the air bag which is made of rubber coated synthetic-tire-cord fabrics
What is total length of air bag?
It is overall length of the air bag
What is the type and model of air bags?
Marine air bags are categorized by the following two types according to the bearing capacity, per meter in lenght:
a) QP – ordinary air bag’
b) QG – high-bearing capacity air bag
What is the size of ship launching airbags?
Diameters of air bag (d) varies such as 0.8m, 1.0m, 1.2m, 1.5m and 1.8m, etc.
Length of air bag (L) is to be specified by the user.
