Abstract: The technical principle of the ship air lubrication drag reduction, the generation mode, the formation mechanism of the bubble, and the influencing factors are introduced in the current study. The state-of-art of the current domestic and the foreign research institutions for the bubble drag reduction and the air layer drag reduction, and their commercial full-scale ship applications are also introduced respectively. It points out that there is a gap in the applications of the air lubrication drag reduction technology at home and abroad, while the bubble drag reduction is more mature than the air layer drag reduction. The problems that should be paid attention to in the application of the bubble drag reduction and the air layer drag reduction are put forward according to the current application status.

Key words: bubble drag reduction, air layer drag reduction, full-scale ship application
