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
【課題】電気推進船の推進システムにおける劣化の主な原因となる機器を特定するのに有効な監視システムを提供する。【解決手段】本発明の一態様に係る監視システムは、プロセッサを有する処理装置と、ディスプレイと、を備え、処理装置は、推進システムにおいて一又は複数の機器を含むように区分けされた各セクションの入力値及び出力値を取得し、入力値及び出力値に基づいて各セクションにおけるセクション効率を算出し、予め記憶した出力値と基準効率との関係に基づいて、取得した出力値に対応する基準効率を算出し、セクション効率から基準効率を差し引いた効率偏差をセクション毎に時系列でディスプレイに表示する。【選択図】図1
