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.
MT-FAST fits multiple blades ahead of the ship’s propeller and thereby reduces both the swirl generated by propeller revolutions and the energy lost in that swirl. Tests have demonstrated that it reduces fuel consumption by about 4%. It can be fitted to both ships under construction and existing ships.
