摘要

In this paper, the electric propulsion has been discussed and evaluated from various viewpoints, for example, fuel saving effect, decreasing sound noise for crew and passenger, optimizing engine room space for making cargo space bigger, improving redundancy of navigation, reducing maintenance work, and suppressing initial cost. After dual fuel engine was developed for 2 cycle marine diesel engine, the electric propulsion has gone to second position or less because of fuel economy and initial cost, especially for merchant cargo ship. On the other hand, it is inevitable system for large cruise liner due to low vibration, low noise, high redundancy, and large hotel load. Recently, autonomous navigation technology has become attractive themes for not only car industry but also marine sector. A part of engineers believe that the electric propulsion system is necessary to realize it. However, it is hard to find reasonable discussions why the electric propulsion is in main stream of the autonomous vessel. Many topics to be discussed has appeared and disappeared in our marine sector.
