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, ship landing work. 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. The biggest vessel launched by ship launching airbags up to **0,**0 DWT.
Ship launching airbags are to be constructed of an out rubber
layer, multilayer heavy-duty synthetic-tire-cord layers, and an
inner rubber layer vulcanized firmly. Ship launching airbags are
cylindrical balloon body, with two conical head and end mouth. Air
tightness swivel and air inlet kits are screwed with end mouth.
Refer below picture.
• Synthetic-tire-cord layer
Reinforcement layer of the ship launching airbags which are made of
rubber coated synthetic-tire-cord fabrics. Many synthetic-tire cord
layers are twined at ideal angles by unique and patented “Holistic
Wrapping Technology“. To hold the internal pressure and to
distribute the stress evenly. Buoder use the ***0 dtex/2 type
synthetic-tire-cord fabric. The warp is over *5 cords per **0 mm in
width, and the breaking strength is more than **0N per cord.
• The outer rubber layer covers the outside of ship launching
airbags. To protects the cord layers from abrasion and other
external forces. This compound has sufficient tensile and tear
strength to withstand any weather condition and hard usage.
Prior to the air bag production, the out and inner rubber layers
are tested to meet the requirements of below table
Inflatable marine airbags can be equipped with the lifting belts
and shackles, used for marine salvage and refloatation work as
marine salvage airbags.
This type marine salvage airbags are the toughest buoyancy units.
It can be used as salvage pontoon for the supporting docks, and
other floating structures. Also can be used to salvage the
shipwreck, rescue the floating bridge and dock construction,
buoyancy loading from any depth water. It really come into own when
marine salvage airbags employed in heavy duty salvage work under
severe environment.
Inflatable marine salvage airbags have better air tigtness than
ship launching airbags. It can be used in water for long time
without inflating air. All end fittings are stainless steel to
resistance the corrosion of seawater. We also can equip the auto
safety pressure relief valves upon request, which can be opened
when the inner pressure reach rated value.
Marine salvage airbags are to be constructed of an out rubber
layer, multilayer heavy-duty synthetic-tire-cord layers, and an
inner rubber layer vulcanized firmly. It has the cylindrical
balloon body, with two conical head and end mouth. Air tightness
swivel and air inlet kits are screwed with end mouth.
Polyester webbing lifting straps are located symmetrically along
the body of marine salvage airbags. The pick points of every strap
are then connect to one screw pin shackle. The total lifting of
these straps shall maintain a minimum 6:1 safety factor of the
operational load.
PVC air lift bags have been widely used for the diving or marine
salvage industry. Our marine salvage airbags are made by multilayer
heavy-duty synthetic-tire-cord layers. It’s more sturdy and
reliability than PVC air lifting bags, which is made only by one
layer PVC coating fabric. The disadvantage of marine salvage
airbags is too heavy, not easy to transport and operate.
Super-high tensile strength – Heavy-duty synthetic-tire-cord layers
is framework material of our marine salvage airbags. The breaking
strength of each synthetic-tire-cord layer is more than *5,**0 N /
5cm, which is two times of PVC coating fabric material.
Resistant to abrasion – The thickness of our marine salvage airbags
is up to *2mm or more. The PVC air lift bag only is about 1.5mm. In
bad environment, the PVC air lift bag is easily scratched or
damaged by sharp objects. But our marine salvage airbags can
resistant the scratch. Even the out rubber was damaged, the inner
synthetic-tire-cord layer also can work well.
Multiple application – Normally, the parachute type PVC lifting
bags used for the lifting work from underwater. The enclosed type
lifting bags used for the buoyancy support of surface. But our
marine salvage airbags are qualified for these two work, because of
its high working pressure and burst pressure.
