The invention discloses a ship air lubrication and resistance reduction system, which belongs to the technical field of marine navigation ships, and is technically characterized by comprising a structure and system, the structure and system comprises an air source device, an air supply pipe system, an air layer bubble generation device, an air escape prevention device and a monitoring control system, the air source device adopts an air compressor and an air bottle, and the monitoring control system adopts an air supply pipe system; the installation position of the air layer bubble generating device is adjusted for normal work of the transducer of the log or the depth finder; and EEDI calculation and verification, the EEDI calculation and verification are used for providing a related calculation method and verification guidance for the ship in which the energy-saving effect generated by the air lubrication drag reduction system is included in an AttinedEEDI calculation value, and the method has the advantages that a proper amount of air is injected into the bottom of the ship body by utilizing the difference between the density and the viscosity of air and water, and the energy-saving effect generated by the air lubrication drag reduction system is calculated by the AttinedEEDI calculation value. And a gas-liquid mixing layer or a gas layer is formed and kept at the bottom of the ship, so that the frictional resistance of the ship is reduced.
