In recent times, there have been a number of studies on reduction in energy consumption in ships. As part of those studies, research to reduce the energy usage of generators and the batteries are underway. In this study, an energy saving method is suggested by comparing a battery-powered ship with an existing ship. For this, we categorized the ship 's operations into different modes and calculated the ratio of the ship's energy consumption for different operation modes for one year. In addition, the average and maximum values of power consumption in each operation mode were obtained and modified to fit the implemented simulator. The experiment was carried out according to the operation mode through the simulator. We calculated the fuel consumption according to the operating mode using the specific fuel consumption (SFC) curve and the engine load obtained from the experiment. The energy saved is calculated by multiplying fuel consumption and operating rate.
