In ships with electric driven or electro-hydraulic driven cargo handling equipment, good care should be given in designing ship's power sources. Because the required electric power for cargo handling equipment greatly fluctuates in a short period, how to evaluate this electric power is the point in determining the capacity of generators. Various studies have been made on estimation of this electric power, and actually the results have been taken into consideration in planning power sources of ships. We present, in this paper, a statistic estimating method which has been so far studied, and describe its application to actual ships, how the generators will be affected by the fluctuating electric power and to what points attention should be paid in designing power sources of ships.
