Document Type and Number:
Japanese Patent JP6898796
Kind Code:
B2
Abstract:
To provide a monitoring system effective for identifying a device which is a main cause of deterioration in a propulsion system of an electric propulsion ship.SOLUTION: This monitoring system according to an embodiment of the present invention is provided with: a processing device that has a processor; and a display. The processing device acquires an input value and an output value of each of sections divided so as to include one or more devices in a propulsion system, calculates section efficiency in each section on the basis of the input value and the output value, calculates reference efficiency corresponding to the acquired output value on the basis of a relationship between the prestored output value and the reference efficiency, and displays efficiency deviation obtained by subtracting the reference efficiency from the section efficiency time-sequentially for each section.SELECTED DRAWING: Figure 1
