Just imagine, a ship with just azimuth thrusters, no need of a rudder, bow or stern thruster or a controlled pitch propeller. Azimuth thrusters are such a fine piece of mechanism that it has totally eradicated the use of conventional form of propulsion systems. As a result there is a design available to suit virtually any application. A zdrive or zdrive type of azimuth thruster is a propulsion system. Azipod units can rotate 360 degrees to increase maneuverability and operating efficiency, with the proven ability to cut fuel consumption by up to 20 percent compared to traditional shaftline propulsion systems. As a whole, they might well be more accurately referred to as a propulsion and steering system.
