How Do Marine Salvage Airbags Work?

Marine Salvage Airbags are devices that are filled with air to help lift a sinking or stranded ship. They work like big inflatable life preservers but are made for large ships and heavy objects. .Henger’s Marine Airbags are made of strong, multi-layered rubber. These materials enable the airbag to cope with a wide range of harsh underwater environments. In operation, divers place the airbags underneath a sinking vessel or building and then inflate the airbags. As the airbags fill with air, they expand, creating enough lift to Smooth surfacing bring the submerged object back to the surface.

These airbags are widely used in marine salvage operations. Common applications include shipwreck rescue, bridge platform construction and underwater pipeline laying. As an important tool, they help to recover heavy objects from the water quickly and economically.

Whether it’s the rescue of a sunken ship or the salvage of a submerged structure, Henger’s airbags offer a flexible and efficient solution. We also offer a wide selection of sizes and specifications for different types of salvage tasks, ensuring that we can meet the demands of a variety of complex environments.

How Marine Salvage Airbags Work

Henger’s Marine Salvage Airbags help submerged objects to surface by providing buoyancy through inflation.

The principle of operation is simple. Inflated by an air pump, the airbag generates strong buoyancy underwater, lifting the sinking object from the bottom. By controlling the inflation rate of the airbag, the object can rise smoothly and steadily without accidents due to excessive buoyancy. Specific use steps are as follows:

Laying the airbag: The diver places the airbag underneath the wreck or submerged object, usually using a sling to hold it in place. This step needs to be precise to ensure that the airbag is in the correct position to generate buoyancy.

Inflation process: An air pump slowly inflates the airbag. Our airbags are equipped with a safety valve that automatically releases excess air pressure when the air pressure reaches a certain level, preventing over-inflation. When the airbag is inflated, it generates the buoyancy needed to lift the object.

Buoyancy enhancement: By adjusting the amount of inflation, the salvage team can control the rate at which the object rises, ensuring that the object surfaces safely from the seabed.

Key Designs for Marine Salvage Airbags

The design of Marine Salvage Airbags focuses on simplicity and effectiveness, here are a few key designs of the airbags. These designs ensure that salvage airbags can work efficiently and safely in an underwater environment.

Multi-layered construction: the airbag has multiple layers of protection. The outer layer is a strong rubber that can withstand scratches and impacts underwater. It has a strong inner layer of synthetic cord, which acts like a very strong net to help the airbag keep its shape and withstand great pressure. In this way, the airbag will not be easily damaged even in the harsh environment underwater.

Sling and Buckle: Each airbag is fitted with a sturdy sling and buckle to securely fasten the airbag to the object to be salvaged. This ensures that the airbag will not move during the ascent, ensuring safe and stable operation.

Safety valve: the airbag is also equipped with a safety valve. When the pressure inside the airbag is too high, the valve automatically opens to release air. This prevents the airbag from bursting due to overinflation. This feature is especially important for larger airbags, as it can greatly increase the safety of rescue efforts.

Different types of salvage airbags & applications

As a professional Marine Salvage Airbags manufacturer. Henger offer different types of airbags to suit various underwater salvage scenarios. There are two common types of salvage airbags according to different needs:

Fully enclosed airbags: these airbags are particularly suitable for salvage operations in shallow water. For example, if a small boat or an object sinks in shallow water, this fully enclosed airbag can come in handy. It provides stable buoyancy through inflation, lifting the sunken object slowly and safely to the surface. It is characterised by its simplicity of operation and is suitable for light salvage tasks, such as the salvage of small boats, vehicles or pipelines in shallow water.

Rubber Salvage Airbags: For deep sea salvage or lifting heavy loads, Henger’s marine salvage airbags are the best choice. They can withstand extreme pressure and are ideal for wreck rescue and deep sea operations.. Designed with multiple layers of rubber, these airbags are both durable and safe. In addition to being able to carry large vessels, they are ideal for complex tasks such as floating deep water pipelines.

Summary

Marine Salvage Airbags play a key role in marine salvage operations, especially in heavy objects and deep sea salvage. They create strong buoyancy, helping shipwrecks and large underwater structures to resurface. Henger’s rubber salvage airbags are flexible and can be used for different types of salvage tasks. In addition, our multi-layer rubber design ensures durability in harsh environments and is more cost-effective than other salvage equipment. Whether you are rescuing a wreck or working underwater, Henger’s marine salvage airbags are an efficient, safe and cost-effective solution.
