Risk Based Strategies for Inspection & Maintenance (RBI & RBM)

Start Date: 10 Mar 2019
End Date: 14 Mar 2019
Duration: 5
Country: Lebanon/Beirut
Category: Engineering and Technical Programs


Risk Based Inspection (RBI) methodology enables the assessment of the likelihood and potential consequences of pressure equipment failures. RBI provides companies the opportunity to prioritize their equipment for inspection; optimize inspection methods, frequencies and resources; develop specific equipment inspection plans ; and enable the implementation of Reliability Centered Maintenance. This results in improved safety, lower failure risks, fewer forced shutdowns, and reduced operational costs.

The risk-based approach needs:

         To be multi-disciplined

         To be realistically applicable to plant integrity

         Design with future scenarios in mind

         Consideration of all potential degradation mechanisms

         Understanding of the risks involved

         Awareness of Fitness for Service assessment techniques


         To provide clear understanding of the key aspects of Risk Based Inspection, its advantages and limitations

         To provide a clear understanding of how it is linked to reliability-centered maintenance

         Understand how fitness-for-service assessment affects the Risk

         To show you how to develop a successful RBI program at your facility

         Provide you with the practical and effective methods you need to perform practical likelihood and consequence analysis

         Show you how to develop optimum Inspection intervals for individual equipment based on the assessment of the active degradation mechanisms

Training Methodology

The course combines presentation of the key principles, methods, and best practices and enforces the learnings with case studies and Question & Answer workshops to maximize the benefits to the participants. The comprehensive course notes and presentation material will provide valuable reference.
