1. An air supply apparatus for a ship, comprising:
a first turbocharger having a first compressor and a first turbine being drivable by exhaust gas provided from one or more engines, wherein the first compressor is coupled to the first turbine via a transmission between the first compressor and the first turbine, said transmission having a variable transmission ratio such that a speed of the first compressor is changeable with respect to a speed of the first turbine; and
wherein the first compressor supplies air to generate bubbles under a hull of the ship to reduce water-hull friction of the ship.
