Physics-grounded, code-aligned, ASNT NDT Level III led.</p>\n<h2>Equipment + Calibration</h2>\n<p>Instrument selection, reference standards, calibration cadence per the relevant ASTM/ISO/ASME standard.</p>\n<h2>Acceptance Criteria</h2>\n<p>Defect classification + sizing + acceptance limits per construction + in-service codes.

Record which examination and acceptance references they invoke; do not assume that standards from different applications are interchangeable.</p>\n<h2>Mandatory vs Non-Mandatory Appendices</h2>\n<p>Check the status of annexes, appendices and referenced documents in the applicable edition. Resolve proposed departures through the authority responsible for the work; the route depends on the governing requirements.</p>\n<h2>Inspector Qualification + Method Authorisation</h2>\n<p>Confirm the personnel qualification and authorisation requirements invoked for this work. Record who performs the examination, who reviews the results and who has authority to decide disposition. These responsibilities are not identical in every scheme.</p>\n<h2>Acceptance Criteria + Defect Disposition Decision Tree</h2>\n<p>Describe each indication using the characteristics required by the examination procedure. Apply the specified acceptance rules within the authorised scope and refer unresolved findings to the responsible technical authority.</p>\n<h2>Common Audit Findings + Atlantis NDT Procedure Pack</h2>\n<p>For the review, retain the applicable procedure revision, personnel authorisation, equipment checks, location references and examination results. Ask the customer which additional evidence and approvals the contract requires.</p>\n\n<h2>Damage Mechanisms (API 571 Cross-Reference)</h2>\n<p>API RP 571 enumerates damage mechanisms in refining + petrochem service. For refining, the dominant mechanisms include: sulfidation (API 571 &#xA7;4.4.2), naphthenic-acid corrosion (&#xA7;4.4.6), high-temp H2 attack / HTHA (&#xA7;4.5.1), amine-stress corrosion (&#xA7;4.5.4), sour-water cracking (&#xA7;5.1.3), CUI / corrosion-under-insulation (&#xA7;4.3.4), MIC / microbiologically-influenced corrosion (&#xA7;4.3.8), erosion-corrosion (&#xA7;4.2.14), and chloride stress corrosion of austenitic SS (&#xA7;4.5.1.4). Atlantis NDT Level III consulting (<a href=\"/consulting/ndt-consulting-level-iii\">consult here</a>) maps each circuit to its dominant mechanism + recommends method.</p>\n<h2>RBI per API 581 &#x2014; Risk-Driver Decomposition</h2>\n<p>RBI per API RP 581 decomposes consequence + likelihood for refining equipment: (1) Generic Failure Frequency (gff) by component class; (2) Damage Factor (DF) per active mechanism; (3) Inspection Effectiveness Factor (A-E) based on prior inspection thoroughness; (4) Consequence &#x2014; Financial + Safety + Environmental.<a href=\"/erp\">Atlantis ERP</a> for live data.</p>\n<h2>FFS per API 579 &#x2014; When + Why</h2>\n<p>Where findings require engineering assessment, the responsible integrity team must define the assessment scope, necessary measurements and applicable methodology. Atlantis NDT can discuss examination evidence; it does not provide an engineering fitness-for-service assessment.</p>\n<h2>Atlantis NDT Stack Configuration for refining</h2>\n<p>Atlantis NDT delivers integrated stack for refining operators: <a href=\"/erp\">Atlantis ERP</a> (NDT reports, technician certificates, crew dispatch and equipment calibration), <a href=\"/digital-twins\">Digital Twin platform</a> (3D asset model with overlaid damage-mechanism heat-map), <a href=\"/best-ndt-reporting-software-2026\">Reporting Software</a> (offline mobile capture with code-aligned templates), and <a href=\"/lms\">Atlantis NDT LMS</a> (continuous inspector cert refresh per refining-specific scope). Affordable, accessible, fully customizable.</p>\n<h2>Frequently Asked Questions</h2>\n<h3>Q1: What is the typical scoping conversation cover?</h3>\n<p><strong>A:</strong> Asset-class scoping, damage-mechanism review (per API 571), code-stack mapping (ASME + API + ISO + NACE + EN), inspector roster review, software-stack scoping, delivery model preference. Tailored quote on request.</p>\n<h3>Q2: How does this fit our vertical operational model?</h3>\n<p><strong>A:</strong> Atlantis NDT delivers vertical-specific procedure packs + inspector cert rosters + asset-integrity playbooks. Free 30-min discovery call scopes your specific asset class + damage mechanisms + code requirements + delivery model preference.</p>\n<h3>Q3: How does AI-assisted defect detection get code acceptance?</h3>\n<p>Automation needs a documented scope, representative performance evidence and an agreed review process. Confirm whether the governing examination requirements permit the proposed technique. A software feature or general risk-planning standard does not establish code acceptance.</p>\n<h3>Q4: What is the typical implementation timeline?</h3>\n<p><strong>A:</strong> 4-20 weeks depending on team size + scope. SMB: 4 weeks. Mid-size: 8-12 weeks. Enterprise multi-region: 12-20 weeks. Atlantis NDT delivers phased rollout with clear milestone gates.</p>\n<h3>Q5: Does Atlantis NDT publish pricing?</h3>\n<p><strong>A:</strong> No &#x2014; pricing varies by region, scope, delivery model, and team size. Atlantis NDT is positioned as affordable, accessible, and fully customizable. Free 30-min consultation + tailored quote.</p>\n<h3>Q6: How does Atlantis integrate with our existing stack?</h3>\n<p><strong>A:</strong> Atlantis ERP has an open REST API, so it connects to SAP, Maximo, NetSuite or any other system that accepts API connections; each integration is scoped with you during implementation. Free integration scoping consultation.</p>\n<h3>Q7: How do I start?</h3>\n<p><strong>A:</strong> Request a free 30-min consultation at <a href=\"/contact\">/contact</a>. We reply within one business day. We scope your asset class + damage mechanisms + code requirements + delivery model preference + integration needs in a single call.</p>\n<h2>Related Atlantis NDT Resources</h2>\n<ul><li><a href=\"/asnt-certification\">ASNT certification</a> &#xB7; <a href=\"/api-510-certification\">API 510</a> &#xB7; <a href=\"/api-570-certification\">API 570</a> &#xB7; <a href=\"/api-653-certification\">API 653</a></li><li><a href=\"/consulting/ndt-consulting-level-iii\">ASNT Level III consulting</a></li><li><a href=\"/erp\">Atlantis NDT ERP</a> &#xB7; <a href=\"/digital-twins\">Atlantis Digital Twin platform</a> &#xB7; <a href=\"/best-ndt-reporting-software-2026\">NDT reporting software</a> &#xB7; <a href=\"/marine-offshore-ndt-services\">Marine &amp; offshore NDT</a></li><li><a href=\"/lms\">Atlantis NDT LMS</a> &#xB7; <a href=\"/ai-ndt-defect-detection\">Atlantis AI for NDT</a> &#xB7; <a href=\"/ccs-inspection\">CCS inspection</a> &#xB7; <a href=\"/atlantis-academy\">Atlantis NDT Academy</a> &#xB7; <a href=\"/atlantis-partner-program\">Atlantis Partner Program</a></li></ul>\n<p>Atlantis NDT &#x2014; Anoop Rayavarapu (ASNT NDT Level III).
