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, led by an ASNT NDT Level III. Atlantis is not an Authorized Inspector; your own AI stays inspector of record.

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 reviewer with no stake in the inspection execution, finds those gaps before the regulator does. The review follows the structure jurisdictional inspectors use, so you get a realistic preview — and a prioritised remediation roadmap to close the gaps on your own schedule.

Patterns a program review commonly surfaces at refining, petrochemical and upstream sites.

Atlantis is not an API 510 Authorized Inspector. Your own AI or Authorized Inspection Agency stays inspector of record and signs what the code reserves for the AI.

Founder Anoop Rayavarapu holds ASNT NDT Level III in UT, RT, MT, PT and VT, for NDE procedure review and examiner qualification audit.

The review is aligned to the regulatory body that applies to your plant — ABSA, TSSA, Texas BPV, OSHA PSM, Aramco, ADNOC, PESO, OISD, JKKP or Migas.

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 and any other methods in your program), 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, phased by risk.
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
Every API 510 requirement in scope checked against a documented evidence artefact
Conformance, observation, minor and major non-conformance, each with the evidence behind it
A remediation roadmap with owners and priorities, phased by regulatory and integrity risk
Inspection-of-record matters stay with your own API 510 Authorized Inspector or Authorized Inspection Agency
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. Plants also commission audits proactively before a planned RBI rollout, MoC overhaul, or owner-user re-certification.
API 510 itself does not specify auditor qualifications. Atlantis program audits are led by founder Anoop Rayavarapu, ASNT NDT Level III in UT, RT, MT, PT and VT, with 11+ years of international NDT field experience. Atlantis is not an API 510 Authorized Inspector: the audit reviews your program against the code and the evidence, and your own Authorized Inspector or Authorized Inspection Agency remains the inspector of record.
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.
