The Navy is developing the technology base for high power electric ship drive machinery which will be reduced in size compared to current units. The location and operating flexibility of such systems can significantly reduce both machinery space and fuel tankage requirement with a consequent reduction in ship size. The availablity of small diameter, high torque motors can make propulsion pods a feasible alternative to open shaft propeller arrangements further reducing ship size by reducing appendage drag and main hull volume requirements and improving propeller efficiency. Propulsion pods may additionally permit quieter propeller configurations and improve construction and machinery replacement by external mounting. This study compares podded electric propulsion to conventional mechanical and electrical drive arrangements. Comparison parameters are ship size and displacement, energy consumption, performance, arrangement, damage stability and maneuverability.
