Inspection and Monitoring | Plant Asset Management

Inspection and Monitoring | Plant Asset Management

  1. What mechanisms are used to determine requirements for inspection activities?
  2. What guidelines are used to determine requirements for monitoring damaging mechanisms (such as corrosion, vibration, flow conditions causing erosion or corrosion, etc.); and also for mitigation of these?
  3. Are all corrosion monitoring and inspection locations/datum points clearly identified within engineering drawing (P&IDs, isometrics) and within applicable workpacks?
  4. What guidelines are there for carrying out and reporting “opportunity” inspections, e.g., as part of unplanned equipment downtime?
  5. What procedures are used to inspect normally inaccessible areas of plant?
  6. How are the requirements and qualifications of Inspectors determined?
  7. What is the criterion used to certify inspectors for an inspection process? Are these issued by International Certification Agency or by the plant?
  8. What procedures are used to determine inspection datums, e.g., TMLs?
  9. How are inspection anomalies managed? – Is there a defined procedure highlighting the actions required for each level of anomaly?
  10. Does minimum design thickness data exist for all vessels? If not, what procedures are applied?
  11. What are the minimum acceptable wall thicknesses for piping systems? Have these been calculated according to a recognized standard, e.g., ASME B31.3?
  12. Details of inspection workpacks?
  13. Is appropriate consideration given to the limitations of inspection and monitoring techniques during evaluation of the data?
  14. What procedures are in place to define the requirements for inspection deferrals?
  15. Does the asset produce an annual Integrity Statement or Integrity Status Report?
  16. Are any areas of plant specifically excluded from inspection or monitoring programs?
  17. Are corrosion control matrices employed to monitor and control the main corrosion threats?
  18. Are corrosion inhibitor dosing levels correlated with fluid volumes to optimize dosing?
  19. How are corrosion rate excursions investigated (and correlated with production/chemical data)?
  20. How are remedial actions achieved? For example what procedures are used to optimize inhibitor treatments?
  21. What procedures are in place to ensure that corrosion probes (e.g., ER or LPR) are functioning?
  22. How often are corrosion coupons retrieved for weight loss assessment and examination?
  23. What procedures and frequencies are used for the management of corrosion probe data?
  24. What procedures are used to evaluate the root cause of corrosion incidents and process upsets leading to increased monitored corrosion rates?
  25. What procedures are in place to examine insulation systems and prioritize refurbishment and inspection programs?
  26. Have non-invasive techniques for CUI been successful in detecting areas of damage or wet insulation?
  27. Are paint specifications applied for repainting programs – do these reflect current best-practice?
  28. Are paint inspectors employed to oversee repainting works? Are the certified by SSPC (NACE) or by other authority?
  29. Are written procedures in place for all inspection and monitoring activities?
  30. How is the Inspection History of each item stored – electronic or otherwise? Is it easily retrievable?
