This paper discussed chosen operation and diagnostic problems with steam turbines in steady states. Wear rate monitoring is the main goal. The material creep affects components wear under heat load in steady state. The paper presents the methodology of comprehensive diagnostic information development, which supports operation, repair and modernization decision. An example is shown of such a support based on operation decision making in order to decrease its components wear rate.
