Marine Air Bubble Lubrication Systems (MALS) are being developed to increase ship energy efficiency. These systems release compressed air from an air blower to reduce friction between the ship’s hull and seawater, using the air bubbles as a cushion.

Calnetix Technologies’ Magnaforce™ PM motor on Powerflux™ magnetic bearings directly coupled to the compressor’s impeller eliminates bulky, low-speed motors and oil lubricated gearboxes, which require a significant amount of space and maintenance, increasing efficiency and reducing maintenance costs for ship owners and operators.
