What are the advantages of airbag devices ?

When a ship navigates in shallow water, it will generate shallow water effects, increase resistance, cause the hull to sink, intensify wave propagation, and even capsize small boats. When some deep draft vessels have limited draft and cannot fully load the tide, airbag devices can be used to make the vessel float and pass through channels with insufficient water depth. In the lower reaches of the Yangtze River in Jiangsu Province, there are many low freeboard sand boats and barges. If there is a little wind and waves on the river, there is a risk of the ship sinking. The airbag device can provide reserve buoyancy for the barge, which can be released into the water in harsh sailing environments, increasing the buoyancy and stability of the vessel and reducing the risk of accidents.

Stranding refers to a state in which a ship cannot navigate when it is placed on an obstacle, except for navigation, anchoring, and berthing. Obstacles include underwater objects such as reefs, shallow waters, sunken ships, etc. that hinder the navigation of ships. After the ship ran aground, it was unable to leave the shallow water area on its own. Airbags can be placed around it to inflate and provide buoyancy, reduce the draft of the ship, and with the help of the airbag device, move it away from its resting position. When a ship is placed on shallow waters or reefs, the present invention can provide buoyancy and support for the ship, prevent the ship from tilting and causing secondary damage to the hull, and assist the ship in escaping shallow water. At the same time, in the waters of the sea or port, if two ships collide or other reasons cause damage to the ship and it is unable to maintain stable upright floating, the airbag device can effectively compensate for the loss of buoyancy in the damaged cabin of the ship, allowing the ship to quickly leave the accident area with less external assistance and avoid traffic congestion in the water.

The airbag device has many unique advantages when used to assist ships in navigation and rescue maritime accidents:

(1) Airbag device is a ship launching and transportation tool in China. Chinese scholars and experts have conducted years of research on the manufacturing and application of airbag devices, and the theory and technology of new ship launching technologies can be successfully transplanted to assist ship navigation and sunken ship salvage.

(2) Marine airbag repair manufacturers believe that installing airbag devices on commercial or engineering ships can increase their stability during rough sailing, reduce sailing risks, and provide passengers and crew with a more comfortable sailing environment.

(3) The airbag device can increase the buoyancy of deep draft ships, reduce their draft, and enable them to safely pass through waterways with limited draft. For stranded or damaged ships, airbag devices can provide reserve buoyancy, maintain the stability of the ship, enable the ship to escape autonomously, and save the required manpower and material resources.

(4) In terms of salvaging sunken ships, airbag devices can effectively compensate for the defects of steel floats and soft floats, and can be used as a substitute for steel floats or as an auxiliary means of correcting the floating state of sunken ships; Meanwhile, the airbag device provides a solution for controlling the floating speed of sunken ships and ensuring the safety of floating vessels.
