Recently an air lubrication method (ALM) has been recognized as one of promising techniques to save energy in naval engineering. In the present article, a brief introduction of ALM in naval architecture is presented. Since ALM requires the additional power to inject air bubble beneath the ship bottom, an air supply method with much less energy consumption should be a key technology to make ALM be promising method for large ships. A scavenge gas bypass method is proposed as one of breakthrough technologies. In the article, recent application of ALM to large commercial ships, including the scavenge gas bypass system, is introduced.
