Buoy salvage method, also known as Marine air bag salvage method. This is the most common method of wreck salvage, by filling the buoy with water, sinking to the bottom, and then adjacent to the ship, the water in the buoy can be salvaging the wreck. In the process of wreck salvage, in order to ensure that the wreck can have a rough trim Angle and floating rate in the process of floating, and maintain the strength of the ship position after the wreck comes out of the water, it is usually decided to float the wreck out of the water in the low tide era. Therefore, in the development of salvage plans, it is necessary to strictly control the amount of buoyancy at the time of formulation to specify the number of rules, which may lead to unexpected circumstances, so that the salvage obligation will prevail.

Second, full internal buoyancy fishing method. In this way, if the high pressure atmosphere is output to the shipwreck cabin to form a fixed internal buoyancy and make the shipwreck float up gradually, it can save a large amount of underwater sealing obligation, and it will float and sink the ship first in the stormy sea area, drag the wreck to the shallow water area or the sea area with less wind and waves, and then stop sealing.

Third, the large floating crane lifting method, this method is mainly assumed to be used for large shipwreck salvage.
