Abstract
An air supply apparatus for a ship is described. The air supply apparatus includes a first turbocharger having a first compressor and a first turbine being drivable by exhaust gas provided from one or more engines. The first compressor is coupled to the first turbine via a transmission configured for changing a speed of the first compressor. Additionally, the air supply apparatus includes an air lubrication device for resistance reduction of the ship. The first compressor is connected with the air lubrication device for supplying air to the air lubrication device.
Claims20
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.
A ship comprising an air supply apparatus, the air supply apparatus 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 lubrication device.
A method of supplying air for air lubrication of a hull of a ship, comprising:
- driving a first turbocharger by using exhaust gas from one or more engines;
- changing a speed of a first compressor with respect to a first turbine of the first turbocharger by using a transmission coupled to the first turbine and to the first compressor of the first turbocharger, said transmission between the first turbine and the first compressor, wherein the transmission has a variable transmission ratio such that the speed of the first compressor is changeable with respect to a speed of the first turbine;
- and
- supplying air from the first compressor of the first turbocharger to generate bubbles under a hull of the ship to reduce water-hull friction of the ship.
