5 days
EIM/PLINS-E
Sessions
This course is not scheduled.
Who should attend?

Audience

    • Managers, experienced engineers and staff involved in inspection, maintenance and operation in the petroleum, petrochemical and chemical industries.

Level

  • Foundation
  • This course covers the necessary background for setting up RBI for static equipment.
Learning Objectives
  • Upon completion of the course, the 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.
Course Content

FUNDAMENTALS OF RISK BASED INSPECTION

0.5 day

  • API 580 overview, concept, probability & 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

2 days

  • Corrosion loops based on process conditions.
  • Design data and inspection data identification.
  • Damage factors identification based on corrosion standards such as API 571.
  • Calculate probability of failure based on damage factor - Quantitative approach using API581 workflow.
  • Calculate consequence of failure - Quantitative & 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 industrial RBI strategy implemented.
  • RBI Semi quantitative approach based on simplified excel spreadsheet.

APPLICATION OF THE RBI METHOD WITH MINI-PROJECTS CASE STUDIES

2.5 days

  • 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 simplified excel spreadsheet and compare the 2 methods.
  • Each group present its RBI analysis and conclusion.
Ways & Means
  • An interactive course based on actual case studies.
