Marine Airbags For Ship Launching And Landing Marine Airbag 008mpa
Floating Marine Airbag
The main supporting elements of the slip are air bag . Ship
transferring from the building area to the slip is produced
approaching the deflated air bag under the vessel and inflating
with compressed air. The launching is made on the air bags used as
the rollers. This launch can be both uncontrolled and controlled.
In the latter case the launching speed is regulated by the traction
mechanism which is located at the head of the slip.
The distance between the air bags depends on the light-ship, the
length and width, but not more than 6 m from the bag centers. To
install the bag the space at least 25 cm in height and width at
least the half of the circumference of the air bag is required.
Construction features
1. Outer and inner Rubber Layer
The outer rubber layer that covers the outside of marine airbag to
protect under layers from abrasion and other external forces.
This compound has sufficient tensile and tearing strength to
withstand any condition and hard usage.
2. synthetic-tire-cord layer for reinforcement
The reinforcement cord layers,which are made of synthetic-tire-cord
commonly used in tires, are arranged at ideal angles to hold the
internal pressure and distribute stress evenly. So they can provide
strong efficient reinforcement
3. End Fittings
End fitting include Air Tightness swivel and Safety Air Inlet.
*These end fittings are enclosed when airbags leave our factory.
| Diameter | 0.5-2.5m |
| Length | 5-26m |
| Cord Layers | 3-12 layers |
The requirements of launching ship and relevant equipments.
1.Ship
The engineering work under water line shall wholly be finished,
especially those equipments, valves and others that are to be
installed at the openings under ship waterline,the installations
should be approved by inspection. All the burrs, welding beading
and the like on the ship bottom or appendages should be ground
away. All the welds on the shell plate must pas inspection and
tightness test. The main dimensions of the ship should be measured
up and the mark of loadline must pass inspection. All the paint
work of the shell plate has been finished.
2 Ramp way
The ramp way on which the airbags will rolling should be cleaned
and be clear of sharp fends such as iron nail. The ramp way should
be leveled and the level error from left to right should less than
80mm. The ground caved in should be filled up and the ground
bearing capacity should be relatively equalized. The ramp made of
mud land, sanded land, sands or concrete, however, its bearing
capacity should be twice as big as the working pressure of airbags.
The slope of ramp is to be determined according to the size of the
launching ship and is generally no bigger that 1/7. In the range of
the whole length of the ramp way, the shape may be of multiple
combination with slope line, are line and others. However, the ship
bottom should not contact the ground even when the airbags are at
their lowest working height. The ramp way should extend into water
for certain length.
3.Winch
In general, a slow winch is to be selected, its veering speed is
about 9-13/m/min. The moving speed of a ship must not be more than
6m/min with the control of hauling force of winch wire. If the ship
weight is less than 200t, the moving speed can be increased
properly. The wire must be inspected and replaced regularity.
4.Air compressor
The type and capacity of the air compressor is to be selected
according to the total volume of all the airbags provided for the
launching and time required for air filling and the air pressure.
The gas tank of air compressor should be installed with adjustable
pressure limiting valve.
1.For ship upgrading, conversion or new/repair launching (Ship
launching airbags)
2.Marine airbag for salvaging sunken ship or heavy immersed steel
structure
3.For hoisting and transporting heavy goods up to 10,000 tonnes
structure on land
4.For floating use purpose as improve the draft.
5.Pneumatic rubber core for architecture engineering Container for
storing and transporting gas and corrosive chemical liquid and
pure water for voyage
6.Rubber bag for ship ballast
7.Rubber airbags used for culvert making.
