Temporary Bridge Barrier Field Inflatable Marine Salvage Underwater
Rescue Air Lift Bags
Marine salvage airbags are the system of choice where reliable, controllable buoyancy is
required. They are particularly suited for installation buoyancy on
pipeline float-out, beach pulls, and river crossings. Our marine
salvage rubber airbags have also been used in applications such as
vessel and platform draught reduction in limited water depths. And
as salvage pontoons for temporary bridges and docks. The salvers
can use marine rubber airbags to salvage the shipwreck, rescue the
floating bridge, and dock construction.
Floating Assistance Salvage And Rescue Field Salvage Rubber Airbags
for Sunken Ships or Offshore Facilities
Marine salvage and floatation is another application of ship
launching marine airbags after update. Doowin Marine marine salvage
airbags are designed with lifting belts and shackles equipped on
the updated ship launching airbags.
Marine Salvage Airbags are the toughest air lifting bags. They can
be used as salvage pontoons for supporting docks and other floating
structures. Also suitable for shipwreck salvage, floating bridge
rescue, and dock construction. With the strongest pneumatic rubber
body, these salvage rubber airbags excel in heavy-duty salvage work
under severe environments.

Compared with steel floats, the advantage of lightweight pneumatic
buoyancy airbags is that they can obtain great buoyancy assistance
with lower economic investment, and can be used to complete tasks
such as underwater installation of steel components and ship
salvage.

bags
Primary Applications
Marine salvage airbags excel in demanding environments where
reliable, controllable buoyancy is essential. They are particularly
effective for:
- Pipeline float-out operations
- Beach pulls and river crossings
- Vessel and platform draught reduction in shallow waters
- Temporary bridge and dock pontoons
- Heavy-duty salvage operations in severe conditions

All Doowin Marine marine salvage airbags are manufactured and
inspected fully compliant with ISO 14409 "Ships and marine
technology - ship launching air bags" and IMCA D016, certificated
by CCS, LR, BV.
Why Choose Rubber Marine Salvage Airbags
Rubber marine salvage airbags are made by multilayer heavy-duty
synthetic-tire-cord layers. They are more sturdy and reliable than
PVC air lifting bags commonly used in the diving or marine salvage
indury.
- High Buoyancy Capacity - Salvage rubber airbags create high buoyancy capacity with safer
air pressure, ranging from 4t to 300t.
- Deep Water Operation - These marine salvage rubber airbags can be used for deepwater
salvage lifting and can be equipped with safety valves.
- Abrasion Resistant - Salvage rubber air bags feature 6-12 plies reinforcement layers
to withstand most abrasion and puncture.
Structure of Marine Salvage Rubber Airbags
Marine salvage airbags are equipped with lifting belts and
shackles. For larger sizes, we install safety valves that
automatically release inner air-pressure when reaching the rated
value.
You can select the required diameter and effective length for your
projects. The specifications shown are standard arrangements, but
we can supply other specifications upon request, with buoyancy
capacity up to 300 tons.
