Marine Salvage Airbag

Marine Salvage Airbag

Overview:

A marine salvage airbag is a specialized inflatable device used in maritime operations to raise sunken or grounded vessels from the seabed or shallow waters. It is designed to provide buoyancy and lifting force by utilizing compressed air.
The airbag consists of a durable and flexible outer rubber layer, typically made from reinforced synthetic materials that can withstand the harsh marine environment. Inside the outer layer, there are several airtight compartments or chambers, often arranged in a cylindrical or spherical shape. These chambers are interconnected to allow for even distribution of air pressure.
To deploy the marine salvage airbag, it is first positioned strategically around the submerged or stranded vessel. Compressed air is then pumped into the airbag using specialized equipment, filling the compartments and causing the bag to inflate. As the airbag expands, it creates a lifting force underneath the vessel, helping to dislodge it from the seabed or the shallow area.
One of the key advantages of marine salvage airbags is their versatility and adaptability to different vessel sizes and shapes. Multiple airbags can be used simultaneously, and their placement can be adjusted based on the specific requirements of the salvage operation. Additionally, the buoyancy and lifting capacity of the airbags can be controlled by adjusting the air pressure, allowing for precise control during the lifting process.
Marine salvage airbags are widely used in ship salvage operations, wreck removals, and other maritime rescue missions. They offer a cost-effective and efficient alternative to traditional salvage methods such as cranes or dry docks. The use of airbags minimizes the need for heavy equipment and infrastructure, making them particularly useful in remote or inaccessible locations.

Advantages of Marine Salvage Airbag:

. Not easy to be affected to wind and wave;

. Easy to transport and store while the airbags are deflated;

. Super-high tensile strength;

. Excellent resistance against abrasion and scratch;

. Low maintenance;

. High flexibility and cost effectiveness.
