Risk Based Inspection
based on API RP 580 & API RP 581
About the course:
The risk-based approach requires a systematic and integrated use of expertise from the different
disciplines that impact plant integrity. These include design, materials selection, operating parameters
and scenarios, and understanding of the current and future degradation mechanisms and of the risks
involved.
Risk-Based Methodologies enable the assessment of the likelihood and potential consequences of
equipment failures. RBI (Risk-Based Inspection) provides companies the opportunity to prioritize
their equipment for inspection; optimize inspection methods, frequencies and resources and develop
specific equipment inspection plans. This results in improved safety, lower failure risk; fewer forced
shutdowns, and reduced operational costs.
Who should attend?
Inspection maintenance, production and other plant engineers and technicians responsible for the safe
on-going operation of pressure containing equipment in oil and gas facilities.
The Participant will learn:
How to apply fundamental principles of risk analysis, using practical application through case histories
and a step-by-step evaluation process for each type of damage mechanism
How to quantitatively determine probability of failure of pressure equipment, analyse consequences of
failure and develop an appropriate inspection plan
About the fundamental principles of component integrity, application of the API rules, material
properties of strength and toughness, and the introduction to stress and fracture mechanics
How to assess the integrity of equipment and make projections about its remaining useful life
Assessment of existing static equipment to increase the equipment capacity and to extend service life
time. API 579-1/ASME FFS-1 provides calculations that can be used to re-rate the component.
To apply and use API RP 580 and API RP 581 recommended practices. For pressurized components
(e.g. pressure vessels and piping), these assessments can be used to determine optimum inspection
intervals through the considered application of ASME section V NDE techniques
