Phased Array Ultrasonic Testing in Stavanger
Multi-element ultrasonic imaging with electronic beam steering for advanced weld and corrosion mapping.
PSA Norway audits NDT records at the asset and corporate level simultaneously — Equinor and partner contractors run NORSOK-grade traceability where a cal-record gap reads as a safety-case deficiency.
How Phased Array Ultrasonic Testing works
A 16- to 128-element transducer is fired with controlled time delays to steer and focus the ultrasonic beam electronically. Sectorial (S-scan) and linear (L-scan) imaging produce real-time cross-sections; encoded scanning produces permanent digital records.
PAUT in Stavanger
Phased Array Ultrasonic Testing in Stavanger is most often pulled into scope when north sea offshore oil and gas or subsea operators need PSA Norway (Petroleumstilsynet)-grade evidence that an asset is fit for continued service. The recurring sites — Equinor Forus HQ and Aker Solutions Stavanger — write PAUT into pre-job inspection plans because multi-element ultrasonic imaging with electronic beam steering for advanced weld and corrosion mapping. Local contractors mobilise calibrated equipment, current ASNT Level II / III credentials, and procedure packages tied to ASME Section V and ISO 13588.

Why PAUT is chosen
Permanent encoded digital record for audit retention
Higher probability of detection vs conventional UT
Replaces RT on many scopes — no radiation exclusion zone
Real-time S-scan and C-scan visualisation
Typical applications
- •Code-case substitute for RT on pipeline girth welds
- •Critical-weld inspection on pressure vessels and piping
- •Corrosion mapping with C-scan visualisation
- •Component-thickness and flaw-sizing on composites
Frequently asked questions
When is PAUT the right method in Stavanger?
PAUT is selected when code-case substitute for rt on pipeline girth welds. In Stavanger, this is the everyday scope at sites like Equinor Forus HQ, where PSA Norway (Petroleumstilsynet) acceptance criteria drive method selection.
Which standards govern PAUT work in Stavanger?
Phased Array Ultrasonic Testing inspections in Stavanger reference ASME Section V, ISO 13588, ISO 19285, ASTM E2491, DNV-ST-F101. Procedure qualification typically rolls up to PSA Norway (Petroleumstilsynet).
What are the limitations of PAUT I should plan for?
Higher equipment cost than conventional UT. Requires Level II PAUT certification plus base UT currency. Procedure development and qualification overhead.
Do Stavanger providers offer encoded / digital PAUT records?
Yes. The NDT Connect provider pool serving Stavanger delivers PAUT packages with encoded scans (where applicable), instrument-level calibration certificates, and Level II/III sign-off — sized to survive PSA Norway (Petroleumstilsynet) audit retention.
How fast can PAUT crews mobilise in Stavanger?
Routine PAUT scopes in Stavanger are typically picked up within 24–72 hours of a posted request. Turnaround and outage support is negotiated against crew rotation — post the scope to NDT Connect to receive parallel quotes from certified Stavanger providers.
