Super-Cavitation Technology to Enhance Fuel Efficiency in Ships

It is no surprise that you might have heard a lot about “Super-Cavitating” technology beforehand. This technology is relevant where we are required to reduce the hull friction. The application of the technology now extends to the design of boats and ships too. It is already proved that the technology will helps to cut the fuel demand in cargo ships by 25- percent.

The improvement in fuel efficiency is achieved with the generation of bubbles, while the cargo ship cruises in the water. An excellent illustration of the technology is hosted in Mitsubishi’s Air Lubricating System (MALS).

The MALS uses the infinite amount of streams of tiny air bubbles created in the bottom of ship, with the help of large powerful air pumps. This bubble will create a layer of air between the body of the ship and water below it.

Now the ship is in a suspended position in the air, over the water. Since the ship isn’t touching the surface of water, friction between the water and hull of ship is reduced. Thus the reduction in friction in turn increases the fuel efficiency and improves the cruising speed.

The Super-Cavitating technology has multiple implications. It will improve fuel efficiency, reduce the time taken for travel, and even reduce the carbon-dioxide emission into the environment.

The military has been interested in the super-cavitation for the increase in speed achieved with it. Russian’s “Shkval” torpedo, which uses this technology, is reported to have a speed of 350 mph, akin to a submarine developed by DARPA, which records a speed of 115 mph underwater. And, the technology is moving on to create more wonders!
