Electric marine propulsion system is 'world's most efficient'

摘要

ABB has announced a new version of its Azipod electric propulsion system for ships, which, it claims, will further increase vessel fuel efficiencies by up to 20% compared to modern shaft line propulsion systems - or 5-10% more than the previous Azipod version. The efficiency gain of the new Azipod XL design is achieved using a nozzle system that accelerates the water flow into the propeller to increase thrust, and by redesigning the thruster to reduce water resistance.
