Risk Based Inspection of Stationary Equipment Course
Introduction:
Course Objectives:
Upon the successful completion of this course, participants will be able to:-
· Identify the degradation mechanism for a corrosion loop,
· Describe the RBI methodology for a petrochemical or chemical plant,
· Determine the probability and consequence of a failure,
· Set up a suitable inspection plan.
· Interpret the definitions and acronyms used in Risk-Based Inspection (RBI) and determine its purpose, scope, approaches, and planning process
Who Should Attend?
The course is aimed to: Managers, experienced engineers, and staff involved in the inspection, maintenance and operation in the petroleum, petrochemical and chemical industries. Also, this course covers the necessary background for setting up RBI for static equipment.
Course Outlines:
FUNDAMENTALS OF RISK BASED INSPECTION
- API 580 overview, concept, probability and consequence of failure, risk ranking.
- API 580 methodology benefits and limits, workforce, and schedule necessary to perform RBI study.
- API 581 scope, probability of failure based on management factor and statistical failure frequency.
QUANTITATIVE & SEMI-QUANTITATIVE RISK BASED INSPECTION APPROACH
- Corrosion loops based on process conditions.
- Design data and inspection of data identification.
- Damage factor identification based on corrosion standards such as API 571.
- Calculate the probability of failure based on the damage factor - Quantitative approach using API581 workflow.
- Calculate consequence of failure - Quantitative and semi-quantitative approach using API581 workflow.
- Evaluate the overall risk on API matrix.
- Define inspection strategy: mitigations actions or inspection scheduling extension.
- Overview of available commercial software “RBEYE”.
- Example of an industrial RBI strategy implemented.
- RBI semi-quantitative approach based on a simplified Excel spreadsheet.
APPLICATION OF THE RBI METHOD WITH MINI-PROJECTS CASE STUDIES
- Application of API 581 RBI method using mini-projects - Case studies as teamwork:
- Select the appropriate corrosion loops and pressure vessels.
- Identify the degradation.
- Apply API 581 workflow to define POF, COF and overall risk.
- Analyze the risk and propose: risk mitigation with more efficient NDT, adapt the inspection frequency.
- Apply RBI semi-quantitative approach based on a simplified excel spreadsheet and compare the 2 methods.
- Each group presents its RBI analysis and conclusion.
