The LPTi offered training module is designed primarily for mechanical and industrial engineers engaged in the operation, maintenance, repair and/or overhaul of gas turbine engines and other types of turbomachinery. The focus is on factors affecting the degradation of engine components and on ways of ensuring the continued safe operation of life-limited parts. The training program also describes procedures for investigating and performing lifing analysis. The training modules help the client to:
● Understand what materials are used in different engine parts and why
● Understand the primary methods used for creep and fatigue life prediction
● Understand what information is necessary to make accurate life predictions
● Understand how to interpret and use life predictions
● Determine what methods will be most effective for their applications
● Maximize use of existing capital investments in aging turbines and reduce risk of catastrophic failures that can otherwise result in lost revenues and service availability, i.e address a classical example of an operator's maintenance dilemma
● Accurately determine when each part on a specific engine in a fleet needs to be replaced based on actual in-service operating conditions and specific damage accumulating
● Accurately schedule inspection and overhaul cycles of each engine in the fleet based on actual usage and operating conditions
● Reduce or eliminate inventory of spares
● Develop intervention strategies for life extension before it is too late
