ABSTRACT: Modern way of machines? exploitation, due to their high level of structural complication, requires proper level of supervising. That supervising is generally based on detection of pre-failure states and evaluation of machines? single elements or components condition. In the frame of development of the research capacity of the Mechanical Faculty of Maritime Academy in Gdynia, has been developed the Exploitation Decision Aid System for marine engines exploitation. The system was based on existing test bed with the marine diesel engine Sulzer AL 25/30 as a core element. Modernization of the measurement equipment, significantly extended research capacity, what resulted with improvement of quality, extension of the span, and acceleration of conducted research and development works in the domain of safety of exploitation and diagnostics of marine power plants. Investments in modern measurement apparatus enables also an extension of the range of research and expertise related to engines? failures and pollutants emission, in relation to broad spectrum of implemented fuels. The goal has been achieved in way of modernization of engine?s monitoring system and stands in Technical Diagnostic Laboratory.
