The article presents the basic assumptions of the research project aimed, as the main scientific purpose, an identification of the slow-changeable energy processes surrounding the high-cycle fatigue of constructional materials within the plain mechanical system, especially the marine one, for diagnostic purposes. There is foreseen an application of alternative diagnostic methods based on energetic observations of the multi-symptom, continuous and irreversible alterations of the fatigue state within the material and construction of the elements transmitting the stream of mechanical energy from the propulsion engine to the propeller. Such methods will represent an essential supplement of already existing diagnosing systems of marine engines as well as marine propulsions. Only then an implementation of the condition based maintenance within the marine propulsion operation can be seen fit to approve. Second part of the paper demonstrates the results of preliminary experimental investigations conducted on the Schenck fatigue machine. The machine has been especially adapted for the purposes of the planned energy research and equipped with measuring apparatus of vibration, acoustic emission and thermal emission.
