How airbags salvage sunken ships

Air bags are also widely used in shipwreck salvage operations. During shipwreck salvage, air bags are often placed on the sides or bottom of the wreck. These air bags inflate to provide buoyancy, allowing the wreck to float or partially float, allowing it to be towed or lifted. Often, multiple air bags are used in different locations to provide adequate buoyancy and support. This method is more efficient and safer than traditional salvage methods, such as using lifting equipment or divers to operate underwater.

The air bag is usually operated through the following steps when salvaging a sunken ship:

1. Assess the site: First, the wreck and its surrounding environment must be assessed. This includes determining factors such as the location, depth, condition of the wreck, seabed conditions, and conditions in the surrounding waters.
2. Determine the salvage plan: Based on the on-site assessment results, formulate an appropriate salvage plan. This may involve selecting the appropriate type and size of air bag, determining where to place the air bag, and determining a plan for air bag inflation and deflation.
3. Airbag deployment: Deploy the airbags to appropriate locations around the sunken ship. Air bags can be placed on the sides or bottom of a wreck, depending on the condition of the wreck and the salvage plan.
4. Inflate the air bag: Once the air bag is in place, you can start inflating it. A high-pressure air source is usually used to fill the bladder with air or other gases to provide sufficient buoyancy to float or partially float the sunken ship.
5. Floating the sunken ship: When inflated, the air bag will provide buoyancy to float or partially float the sunken ship. This facilitates subsequent towing or lifting operations.
6. Control process: During the refloating process of a sunken ship, it is necessary to continuously monitor and adjust the inflation and exhaust of the air bag to ensure the safety and effectiveness of the salvage process.
7. Hoisting or towing: Once the sunken ship is refloated, it can be moved to a target location using a crane, tugboat or other equipment, such as towing to a repair yard or off the waterway.
8. Clean up the site: After the salvage is completed, the site needs to be cleaned up to ensure water safety and environmental protection.

The entire process requires a highly specialized salvage team and equipment to ensure the operation is safe and successful.
