RMC-00-86 RISK-BASED ASSESSMENT OF MECHANICAL DRIVE STEAM TURBINES

Description:

This paper details development of the STRAP model, demonstrates the application of this model in evaluating a single turbine and a fleet of turbines and displays the results achieved through testing of the analysis. The STRAP model is incorporated into a computer program that allows “what if” scenarios for individual turbines to be evaluated on a cost- Risk-benefit basis. These results are then used to optimize the overhaul and inspection process as well as to make sparing and upgrade decisions. The tool also allows for benchmarking of the turbine with other similar size turbines, turbines from the same industry, turbines driving the same equipment, and turbines made by the same OEM.
