Air lubrication Technology

 This refers to a technique by which compressed air is pumped into a recess  in the bottom of the ship’s hull over the length; the entrained air reduces the  frictional resistance between the water and the hull and reduces the propulsion  power demand. An injection system delivers air to the recessed area of the  hull through a system of automated compressors and valves, while a control  system monitors the volume and pressure of air and maintains the optimal  air level in the air cavity. Mitsubishi came out with their Air Lubrication System, it was just one of the several energy-saving techniques for ships. The Mitsubishi Air Lubrication System (MALS) was the first system of its kind which promised energy saving and emission reduction from ships using the innovative technology of Air Lubrication. Abatement potential  10–15% for tankers and bulker carriers, 5–9% for container  vessels. Market barriers Large capital investment requirements, an...
