Summary
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 in long cylindrical balloon shape. Ship
launching airbags can be used for the ship launching or ship
landing of tanker, tugboat or barges, carrying vessel, carrier,
ferry and other special vessels (AHTS, DSV) and so on. The biggest
vessel launched by ship launching airbags up to 100,000 DWT.
Advantage Ship launching relying on ship launching airbags is a innovative
ship launching technology, comparing with "end-on launching", "side
ship launching", "float-out". This ship launching technology
overcomes the restrictions of fixed launching track of side-launch.
Ship launching airbags are accepted by more more shipyard world
wide because of its advantages of saving time, saving investment,
flexible, safety.

Application
Now the marine airbag for ship launching are widely used for
hoisting and transporting heavy structure, refloatation, salvaging
sunken ship or heavy immersed steelstructure, erecting floating
bridge or pipeline in the marine field and shipyards.
tructure of the TEAMWORK marine airbags
Please check TEAMWORK inflatable rubber airbag structure as below.
It is composed by airbag body and terminal iron part. The airbag
body is composed by natural rubber and strength fiber material
through vulcanization processing; The terminal iron part is made of
cast iron, it is combined closely with the bag body; One end is for
pulling when move the airbag, and the other end is for charging and
discharging the air.
"TEAMWORK" Marine Rubber Airbags' structure is consists of the
outer rubber layer synthetic cord reinforced rubber layers and
inner rubber layer.
Its shape characteristics: central body cylindrical + tapered on
both ends. Cord layers:4,5,6,7,8,9,10,1ayers
Accessories: Pressure gage, Inlet valve, Pipe fitting and seal end
ring..
Materials
An airbag is to be constructed of an outer rubber layer, one or
more synthetic-tyre-cord layers, and an inner rubber layer. The
arrangement of synthetic-tyre-cord reinforcement layers is shown in
the picture below, all materials shall be vulcanized firmly.
Prior to the airbag production, the outer and inner rubber layers
shall be tested to meet criteria in the following table in
accordance with the test methods given in the international
standard list in the table. While only one satisfactory sample per
batch is required for test numbers 1 through 3, all others must be
tested for test numbers 4 through 9 annually. If the first sample
fails, two additional sample should be tested. If the additional
samples pass the test requirements, the materials will be deemed to
have passed the test. Otherwise, the materials will be deemed to
have failed the test and another batch of materials shall be
selected.
If the launching airbags or ship landing of tanker, caters to your
requirement, welcome to buy or wholesale with our factory. As one
of the leading manufacturers and suppliers in China, we will offer
you the most competitive price and the best service.
