PROBLEM TO BE SOLVED: To provide a gas turbine component service life management system and a gas turbine component service life management method capable of highly accurately performing management of service lives of gas turbine components by using the crystal orientation of the gas turbine components as a parameter of service life evaluation. SOLUTION: This gas turbine component service life management system is provided with: a crystal orientation measuring means 11 for measuring the crystal orientation of the gas turbine components; a temperature/stress/distortion amount analysis means 12 for calculating the amount of temperature, stress and distortion of the gas turbine components based on the crystal orientation measured by the crystal orientation measuring means 11; a component service life determining means 13 for evaluating inspection timing and remaining service lives of the gas turbine components based on the crystal orientation measured by the crystal orientation measuring means 11 and the temperature, stress and distortion amount calculated by the temperature/stress/distortion amount analysis means 12; and a control means 15 for making determination regarding repair, reuse and discard of the gas turbine components based on the evaluation of the component service life determining means 13.
