Abstract
A life management system for high-temperature parts of a gas turbine has one server system and a plurality of client systems , and , all of which are connected via an Intranet. Further, the server system manages a program for performing evaluation of the remaining life and the life management, and each of the client systems , and has a subprogram for accessing the database and for entering data respectively. The clients are dedicated to different objects and share respective element data such as real component damage, design, materials, etc. which are necessary for the evaluation of the remaining life. Further, this system enables the operation of the gas turbine to be optimized based on the damage of the evaluated parts, hence contributing to operational cost reduction of the gas turbine.
