The hull appendage MT-FAST is an energy-saving device that greatly reduces fuel consumption. Its multiple blades are fitted ahead of the ship’s propeller to reduce the swirl generated by propeller revolutions and thereby enhance propulsion efficiency.

Accelerating the development of innovative technologies to reduce CO2 emissions from vessels is essential to both cope with rising fuel costs and to improve the world environment. This can be achieved through the development of various CO2 abatement technologies, such as low-friction coatings, hybrid contra-rotating propulsion systems, solar power, and liquefied natural gas-fueled plants. We focus on the proprietary Mitsubishi Air-Lubrication System (MALS), which reduces frictional resistance between the vessel hull and seawater using air bubbles along the bottom of the vessel.
