OS6-5 Development of Risk-Based Maintenance Software for Gas Turbines

Abstract

"RISKWISE^<TM> for Gas Turbines" has been developed to perform risk-based maintenance and inspection planning on gas turbine hot gas path components. The software allows the user to easily prepare a risk matrix, plotting every active damage mechanism for each hot gas path component. Based on the result of the risk assessments the components can be ranked, allowing inspection plans to be focused and prioritised and aiding the user to identify the most appropriate and effective risk mitigating activity within the software. Risk assessments are performed on a component by component basis, with the software's scope including all combustor and turbine hot gas path components. The software also contains comprehensive help documents to aid the user in identifying and assessing peculiar damage mechanisms and prescribing the most effective inspection methods for gas turbines.
