API 510 In-Service Inspection Program Audit

Find the gaps before the regulator does. Independent third-party audit of your API 510 in-service inspection program, signed by an active ASNT Level III + API 510 Authorized Inspector.

The trouble is that API 510 compliance is a moving target — equipment populations grow, inspectors retire, AI certifications lapse, RBI claims drift from reality, repair packs go missing, and an inspection program that passed the regulator five years ago can quietly accumulate dozens of minor non-conformances that, in aggregate, produce a major finding the next time the auditor calls. A regulator-driven finding can shut down a unit, trigger fines, or cost the plant its owner-user authorisation.

A proactive third-party audit, performed by an independent API 510 AI with no skin in the inspection-execution game, finds those gaps before the regulator does. Our audits mirror the format jurisdictional inspectors use, so you get a realistic preview — and a prioritised remediation roadmap to close the gaps on your own schedule.

Patterns from 40+ recent API 510 audits across refining, petrochemical and upstream sites.

Active API 510 AI credentials with documented continuing education. Findings reports signed by active AI with number + expiry recorded.

UT, RT, MT, PT, VT, ET — full method coverage for NDE procedure review and examiner qualification audit.

ABSA, TSSA, Texas BPV, OSHA PSM, Aramco, ADNOC, PESO, OISD, JKKP, Migas — audits aligned to the specific regulatory body that matters to you.

60-minute scoping call — free, no obligation, NDA available. We will tell you how big the gap is likely to be, what the audit will cost, and how long the remediation will take.

Key points covered

Element-by-element review of your in-service inspection program against API 510 requirements — owner-user inspection organisation, AI qualification, inspection intervals, NDE methods, repair / alteration / re-rating procedures.
Review of Authorized Inspector certifications, examiner ASNT/ISO 9712 credentials, ongoing CEU/CPD compliance, and the documented authority delegation chain from owner-user to AI to examiner.
Inspection procedures (UT, RT, MT, PT, VT, ET, AET), repair procedures, alteration procedures, and re-rating calculations checked against API 510 + ASME Section VIII + relevant jurisdictional requirements.
Equipment files, inspection history, MoC records, repair packs, and condition-monitoring location (CML) data audited against API 510 §7 record-keeping requirements.
If your program uses RBI-based intervals, the API 580 / 581 conformance evidence is audited — corrosion-loop documentation, LoF/CoF calculations, inspection-effectiveness justification, re-assessment triggers.
A defence binder organised against API 510 Annex A audit checklist — every clause cross-referenced to a documented evidence artefact. Drops into your next regulator or AI body audit.
Prioritised gap-closure plan with effort estimates, regulatory risk weighting, and owner-assigned action items. Most plants leave with a 60/90/180 day plan.
Equipment population, regulatory jurisdiction, recent audit findings (if any) and target completion date agreed. We confirm whether the audit drives toward a third-party certification (e.g., API recognised AI body audit) or an internal compliance review.
Inspection program manual, equipment register, recent inspection reports, AI / examiner certifications, MoC log, repair packs, RBI deliverables — collected via a secure document portal.
Every API 510 clause is checked against documented evidence. Findings categorised as conformance, observation, minor non-conformance, or major non-conformance.
Walk-down of CMLs, AI office observation, examiner interview. Confirms that documented procedures match actual field practice — the most common source of audit failures.
Draft findings reviewed with your inspection team. Genuine non-conformances are confirmed; edge-case interpretations are debated and resolved with documented rationale.
Final API 510 audit report issued. Evidence pack assembled. Remediation roadmap delivered with owners assigned.
Optional re-audit after remediation — typically 60-90 days later — to confirm corrective actions are effective and documented.
Inspection intervals exceeded without documented MoC or extension justification
AI certifications lapsed or examiner certifications expired without renewal
Repair / alteration packs missing R-stamp documentation or pressure-test records
Re-rating calculations performed without API 510 §8 + ASME Section VIII conformance
RBI inspection plans claimed but corrosion-loop documentation incomplete or out of date
CML thinning trends not analysed; corrosion rate not updated; tmin not recalculated
External inspection neglected — coating, insulation, supports, anchor bolts, foundations
On-stream NDT performed but examiner qualification not documented per ASNT SNT-TC-1A / CP-189
FFS performed informally without conforming to API 579 documentation requirements
First-time audit pass at three recent client sites (refinery, petrochemical, upstream)
Material findings on follow-on regulator audits after gap-closure roadmap implemented
No regulator-driven shut-down on any audited plant in the last 3 years
Three common drivers: (1) preparing for a regulator or AI body certification audit (ABSA, TSSA, Texas BPV authority, etc.); (2) corporate process-safety committee requirement for periodic compliance verification; (3) recent incident, near-miss or regulator finding that triggered a remediation requirement. We also see plants commission audits proactively before a planned RBI rollout, MoC overhaul, or owner-user re-certification.
API 510 itself does not specify auditor qualifications, but the recognised practice is an experienced API 510 Authorized Inspector with ASNT Level III credentials, multi-site refinery + petrochemical experience, and demonstrable familiarity with the relevant jurisdictional regulations. Our auditors meet all three criteria and have completed 40+ program audits across the Gulf Coast, GCC, India, Canada and Asia-Pacific.
A regulator audit is binding — non-conformances may trigger shutdown orders, fines or jurisdictional sanctions. Our audit is independent and confidential — non-conformances are findings only, with no regulatory consequence. The point is to find and fix gaps before the regulator does. The audit format closely mirrors what jurisdictional inspectors actually do, so you get a realistic preview.
Yes. API 570 (piping) and API 653 (storage tanks) follow the same in-service inspection program structure as API 510 and use the same Owner-User / AI / Examiner framework. We routinely audit all three programs in a single engagement. The 5-7 day on-site time scales roughly linearly with the number of programs audited.
