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

What are the Goals?

• 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

Who is this Training Course for?

• Operations Engineers
• Maintenance Engineers
• Engineering Managers and Supervisors
• Technical Staff with responsibilities for inspection, maintenance, assessment and mitigation of plant equipment degradation, and who want to use RBI effectively in their plants
