Risk Based Inspection (RBI)

EIM/PLINS-E

Who should attend?

  • This course covers the necessary background for setting up RBI for static equipment.
Audience :
  • Managers, experienced engineers and staff involved in inspection, maintenance and operation in the petroleum, petrochemical and chemical industries.

Level : Foundation

Course Content

  • 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 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

      • 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 presents its RBI analysis and conclusion.

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.

Ways & Means

  • An interactive course based on actual case studies.
