The invention relates to a submergence assisting system for water ballast tanks of an air compressor ballast semi-submerged ship. The system adopts the structure that a ballast make-up water pump is additionally arranged in a ballast adjusting system for the water ballast tanks of the air compressor ballast semi-submerged ship; an overflow collecting pipe, an overflow alarm and an overflow cabin are arranged at the end, near an air compressor, of a water ballast tank vent pipe; the water inlet end of the ballast make-up water pump is connected with seawater tanks; the water outlet end of the ballast make-up water pump is connected with all the water ballast tanks through make-up water adjusting valves; an overflow adjusting valve is arranged in front of the overflow collecting pipe, and communicated with the overflow cabin through the overflow alarm; the overflow alarm is triggered when receiving an overflow signal, and is stopped when receiving an overflow end signal. The system has the key advantages that make-up water facilities for an air compressor ballast system are arranged, that is, the make-up water pump, the overflow collecting pipe, the overflow alarm and other corresponding pipes are arranged, so as to ensure the water ballast tanks can be fully filled with seawater in any working conditions; compared with the prior art, the system provided by the invention can enable the water ballast tanks to be fully filled with seawater, and completely avoid hidden troubles in the ship draught and ship stability caused by the situation that the water ballast tanks cannot be fully filled with seawater.
