The flexibility of machinery layout and control advantages of electric ship propulsion can be realized with the superconducting electrical machines, without the traditional space, weight and efficiency penalty of the conventional motor and generator.<BR>This paper describes the features and problems of the superconducting electric propulsion system including the onboard refrigerating system, and that the use of the superconducting electric propulsion system offers significant applications advantages to future high performance vessels and ice breaking type vessels.<BR>In order to evaluate the applications advantages, the study of the application of the superconducting electric propulsion system is carried out for ice breaking type LNG carrier, which shows that reduction in the required propulsion machinery space and weight permits a 65% reduction in the propulsion machinery space and a 70% reduction in the propulsion machinery weight with no reduction in the installed power, in comparison with the application of the conventional electric propulsion system.<BR>And, the present status of R&D of the superconducting electric propulsion system, in U.S. and U.K., is reviewed.
