Introduction
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
Objectives
·
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.
