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, and the split interest.
