This paper presents a development of the known qualitative method for assessment of engine operation, applied to ship main diesel engine as an example. According to this interpretation engine operation can be presented as a physical quantity. In this aspect, based on the selected functional system of the engine, was assessed usefulness of the quantity for description reliability features of the system. To the analysis was applied Poisson's uniform process which made it possible to elaborate a model of run of worsening the considered system's operation taken as a random process of identical independent decreases of energy efficiency within a given time interval. The presented method is a valuable supplement for description reliability features of ship main engine what is important for realization of shipping tasks by sea. Additional advantage is versatility which makes that it can be applied to reliability analysis of any ship device or ship energy subsystem. Classification of the engine serviceability states with taking into account the assessment of its operation in energy-time aspect, schematic diagram of lubricating system of RTA48-TB engine and values of lubricating oil parameters in steady conditions for the engine load, graphical presentation of lubricating oil cooler operation graphical interpretation of the decreasing of oil cooler efficiency are presented in the paper
