Abstract (en)
A method for monitoring a life usage of at least one engine part of an engine (2) comprising the steps of: (a) detecting (S1) engine parameters of each monitored engine part of said engine (2) to provide engine parameter data of the respective engine part; (b) synchronizing (S2) the detected engine parameter data of said engine part to a common time basis; (c) converting (S3) the synchronized engine parameter data of the respective engine part to derived stress-like parameter data for all detected engine parameters of said engine part; and (d) calculating (S4) a damage value for the respective engine part on the basis of the converted stress-like parameter data to assess the life usage of the engine part.
