IHI GROUP-DEVELOPED 'DUCKPELLER' WIDELY USED FOR HARBOR TUGBOATS

A new type of propulsion equipment with large capacity and high performance has been devloped for use in harbor tug boats. This equipment features a nozzle-propeller driven by the vertical shaft and bevel gears which can turn 360 degrees. This means that the vessel can make full thrust in any desired direction with maximum propulsive efficiency and obtain excellent maneuverability. Some features of this system include: the 360 degree steering unit, thereby eliminating the rudder; the capability to deliver the maximum thrust per horsepower; ease of installation; and remote control by a single lever type remote control unit. Other features and specifications of the system are also listed in the article.
