Introduction
High Load Capacity Marine Rubber Airbag have emerged as a revolutionary technology in the maritime sector.
These airbags play a crucial role in various operations related to
ships, offering a cost - effective, flexible, and efficient
alternative to traditional methods.
Function and Working Principle
The primary purpose of high load capacity marine rubber airbag is to utilize their unique properties of low - pressure air
charging and large - area bearing capabilities. This enables the
completion of airbag discharging or launching operations for ships.
The airbags are designed with specific characteristics. They have a
low inflating pressure, which means that they can be easily
inflated without the need for high - pressure equipment. Their
large bearing area allows them to distribute the weight of the ship
evenly, reducing the stress on any single point. Additionally,
after undergoing large deformations, they are easy to roll.
The process of using these airbags for ship launching is as
follows: First, high load capacity marine rubber airbags are used to lift the ship from the pier. This carefully controlled
lifting action ensures that the ship is safely raised off the
ground. Then, the ship is placed onto rolling airbags. Finally,
steel cables are used to tow both the ship and the airbags,
gradually moving the ship into the water.
Construction and Durability
High load capacity marine rubber airbags are constructed from a composite material made up of high -
strength fabric and rubber. This combination provides the airbags
with the necessary strength and durability to withstand the heavy
loads associated with ship launching and other operations.
One of the significant advantages of this construction is its
repairability. In the event of damage, the airbags can be easily
repaired. This not only extends their lifespan but also reduces the
overall cost of ownership for shipyards and other users.
Application Scope and Adaptability
This method of using high load capacity marine rubber airbag is highly adaptable. It can be applied to launching areas with
different slopes and soil qualities. This flexibility makes it a
viable option for a wide range of shipyards, especially those in
inland rivers.
In China, for example, some small inland river shipyards have
successfully used high load capacity marine rubber airbags to launch small barges, tugboats, and flat - bottom boats with a
dead weight of less than 200T. This shows the practicality and
effectiveness of this technology in different scenarios.
Application Fields of Marine Airbags
Ship Upstream and Downstream
Thanks to extensive practice, the technology of using airbags for
ship upstream and downstream activities has been proven safe and
reliable.
This technology has been widely recognized in the shipbuilding and
port construction industries at home and abroad. It has been
successfully promoted in countries like the US, European nations,
and those in Southeast Asia. It has become popular because it is
flexible, cost-effective, and has a relatively simple operation
compared to traditional ship-launching methods.
Marine airbags are extensively utilized in various aspects of port
construction, especially in caisson jacking, transportation, and
launching. In these operations, the unique properties of high load capacity marine rubber airbags, such as their large bearing area and ability to distribute
weight evenly, make them an ideal choice.
Buoyancy Aid Salvage
Thanks to their high buoyancy and strong load - bearing capacity, high load capacity marine rubber airbags have become a popular choice in the rescue of stranded ships
and other floating salvage operations. They can provide the
necessary buoyant force to lift sunken or stranded vessels,
facilitating the salvage process. This application not only helps
to recover valuable ships and cargo but also contributes to
maintaining the safety and order of waterways.
