The author built a total system for the estimate of electric power consumption by a quayside container crane. The model calculates full motions of the spreader in the first step. Using the data as the input condition, the model calculates the electric power consumption. Comparing the estimates calculated by the model with observed data, the author verifies that the model explains rather precisely actual electric power consumption of the crane. Categorizing the combination of container ships and container cranes, the author calculated unit electric power consumption per handling weight used by the model. The sensitivities of related factors to the unit electric power consumption were also calculated in cases to shift crane specs and handling conditions respectively.
