An autonomous system for blowing ballast for eliminating negative buoyancy of a submarine and a method of blowing the same. The autonomous system includes air supply balloons arranged in an area of the submarine protected from mechanical damage; trunk pipelines connected to the balloons for supplying gas to FDT of the submarine; shutoff devices In submarine technology a vent is a valve fitted to the top of a submarine's ballast tanks to let air escape from the top of the ballast tank and be replaced by water entering through the opening(s) called "flood ports" or "floods" at the bottom of the tank.

Ballast tanks are located between the inner and outer hull of a submarine. When a submarine needs to submerge it fills these tanks with sea water. This changes the buoyancy of the submarine. Special ballast tanks, located forward and aft, are known as “trim tanks.” They are filled with air or water allowing the bow or stern of the submarine to rise and sink. One of the most popular ballast systems in Europe is the Piston Tank Ballast System, made most famous by the German submarine kit manufacturer Alexander Engel. These systems can be quite simple (basically a large plunger moving in a sleeve driven by a motor), or very complicated with multiple tanks and computerized control.
