Use Case

ROV-based subsea pipeline inspection, CP + UT thickness + visual + 3D scan integration. Robotic + drone-based inspection extends inspector reach + improves safety.

Equipment + Payload

Sensor payload selection, calibration + traceability, inspector + pilot dual qualification.

Code Alignment

ASME Section V + API 510/570/653 + IACS Rec 20 acceptance pathways for robotic + drone-collected data.

Atlantis Approach

Atlantis Digital Twin platform ingests drone + robotic data + overlays on 3D asset. Atlantis NDT ERP tracks pilot cert + drone calibration. Free consultation.

Method Physics + Equipment Selection

Defect-detection physics, signal generation, and instrument-selection criteria for this method. Probe + transducer + sensor selection driven by material thickness, expected defect orientation, surface finish, geometric access, and ambient conditions. Atlantis NDT Level III selects the equipment that resolves the dominant damage mechanism in your service — refining sour-service, marine corrosion, aerospace fatigue, power-gen HTHA, or hydrogen embrittlement.

Calibration Block + Reference Standards

Reference standards traced to NIST (US) / NPL (UK) / PTB (DE) / BAM (DE) / NMIJ (JP) / NPL India / NIST China. Calibration block geometry per ASME V relevant Article, ASTM E127/E1158/E2491, ISO 7963/2400 (UT), ISO 19232 (RT), ISO 9934 (MT), or method-specific reference. Calibration cadence: pre-job, every 4 hours, after major adjustment, end of shift. Atlantis NDT ERP automates calibration cert renewal + traceability audit-trail.

Defect Sizing + Through-Wall Resolution

Sizing techniques: amplitude-based (DGS, AVG, DAC), echo-dynamics, time-of-flight, satellite-pulse, focal-law-corrected for PAUT. Through-wall sizing resolution typically λ/2 to λ for the chosen frequency + material velocity combo. Surface-breaking vs embedded discrimination via tandem probe / TOFD parallel-beam / EDM-notch reference. Atlantis NDT digital-twin platform (visualise here) overlays sizing data on 3D asset model for change-tracking across inspection cycles.

Method Limitations + Complementary Methods

This method has inherent limitations — coverage gaps, defect-orientation blindness, near-surface dead-zones, or material-attenuation thresholds. Complementary methods recommended where method limitation creates risk: combine UT + MT for ferritic weld inspection, PAUT + TOFD for full weld-volume coverage, ECA + EC array for stainless weld inspection, IRT + UT for composite bond inspection. Atlantis NDT procedure pack specifies method-pair selection per ASME PCC-3 + API 510/570/653 + EEMUA 159 damage-mechanism guidance.

Atlantis NDT delivers turn-key procedure pack: written procedure (ASME Section V + IX aligned), technique sheet (per defect class), calibration sheet, qualification block, Level III sign-off, inspector training (96% first-pass rate via Atlantis Academy), free retake-grade backstop. Integrated with Atlantis NDT ERP (audit-ready records) + Digital Twin platform (3D defect localisation) + reporting software (offline mobile capture). Free 30-min consultation + tailored quote within 24 hours.

Damage Mechanisms (API 571 Cross-Reference)

API RP 571 enumerates damage mechanisms in refining + petrochem service. For marine + offshore, the dominant mechanisms include: sulfidation (API 571 §4.4.2), naphthenic-acid corrosion (§4.4.6), high-temp H2 attack / HTHA (§4.5.1), amine-stress corrosion (§4.5.4), sour-water cracking (§5.1.3), CUI / corrosion-under-insulation (§4.3.4), MIC / microbiologically-influenced corrosion (§4.3.8), erosion-corrosion (§4.2.14), and chloride stress corrosion of austenitic SS (§4.5.1.4). Atlantis NDT Level III consulting (consult here) maps each circuit to its dominant mechanism + recommends method.

RBI per API 581 — Risk-Driver Decomposition

RBI per API RP 581 decomposes consequence + likelihood for marine + offshore 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 — Financial + Safety + Environmental. Atlantis NDT RBI program design builds the corporate-asset RBI model from ground up — code-aligned, audit-defensible, integrated with Atlantis ERP for live data.

FFS per API 579 — When + Why

Fitness-for-Service per API 579-1 / ASME FFS-1 applies when in-service equipment shows damage exceeding original-design acceptance: general metal loss (Part 4), localised metal loss (Part 5), pitting damage (Part 6), HIC/SOHIC/blister (Part 7), weld misalignment / shell distortion (Part 8), crack-like flaws (Part 9), high-temperature operation (Part 10), creep damage (Part 10A), fire damage (Part 11), dent / gouge (Part 12). Atlantis NDT FFS service delivers Level 1 + Level 2 + Level 3 (FEA-supported) per API 579 — remaining-life recommendation included.

Atlantis NDT Stack Configuration for marine + offshore

Atlantis NDT delivers integrated stack for marine + offshore operators: Atlantis ERP (asset register + circuit hierarchy + inspection schedule + cert tracking + calibration), Digital Twin platform (3D asset model with overlaid damage-mechanism heat-map, RBI tier visualisation, FFS workflow visual), Reporting Software (offline mobile capture with code-aligned templates), and Atlantis NDT LMS (continuous inspector cert refresh per marine + offshore-specific scope).

Frequently Asked Questions

Q1: When should we use PAUT vs TOFD vs conventional UT?

A: PAUT: complex geometry + automated coverage + full-volume scan. TOFD: through-wall sizing precision + crack-tip diffraction. Conventional UT: simple weld geometry + sizing not required. Atlantis NDT procedure pack specifies combo per ASME V Article 4 Mandatory Appendices.

Q2: How does this fit our vertical operational model?

A: 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.

Q3: How does AI-assisted defect detection get code acceptance?

A: ASME V Article 1 establishes "personnel capable of performing the examination" — extends to AI-assisted capture when (1) procedure qualified + Level III approved, (2) AI model validated per ASME PCC-3 + API 581 + IACS Rec-20, (3) human-in-the-loop Level III final disposition.

Q4: What is the typical implementation timeline?

A: 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.
