The Life-Management System (LMS), for optimizing the reliability and maintenance costs of hot-gas-path components, was developed previously. Based on LMS, the Life-Management System with Remote Monitoring (LMSRM) for the real-time evaluation of damage and the residual life times of the hot-gas-path components of gas turbines was developed in the current work. Damage to these components is accurately evaluated by using a new equivalent operating time that takes data gathered by on-line sensors into account. The new equivalent operating time is thus calculated by using the number of start-ups/shut-downs, the number of variations in loading, and by such real-time data, as temperature, pressure, and composition of intake air.
