What tank inspection involves

Aboveground storage tank inspection covers the shell, floor, roof and appurtenances, establishing minimum thickness by course, floor condition, settlement, and the resulting inspection intervals under API 653.

Scope of work

External inspection of shell, roof, appurtenances, foundation and containment
Ultrasonic shell thickness by course with minimum-required-thickness calculation
Floor scanning by magnetic flux leakage with ultrasonic prove-up of indications
Settlement survey and evaluation against API 653 Annex B criteria
Vacuum box testing of floor welds and, where required, hydrostatic testing after repair

Governing codes

API 653 for inspection, repair, alteration and reconstruction, API 650 as the construction code, API 575 for practice, and API 579 where fitness-for-service assessment is required.

The Oman asset base

Oman operates a strategically critical hydrocarbon sector spanning Petroleum Development Oman's onshore production (>700,000 bpd from Mukhaizna, Marmul, Yibal, Lekhwair), the OQ refining complex at Sohar plus the OQ Salalah methanol plant, and the Oman LNG export terminal at Qalhat (Sur) with 10.4 mtpa capacity. The Ministry of Energy and Minerals oversees integrity management across PDO, OQ, BP Khazzan (deep gas), and Daleel Petroleum assets. Remote desert location, sour-gas production, and the strategic location at the mouth of the Strait of Hormuz make digital twin remote-monitoring and life-extension evidence a strong fit for Oman operators.

How the work is controlled

Agree personnel qualification, equipment checks, procedure revision and review responsibilities for the examination. Retain those records with the results and coverage limitations.

What you receive

A report in your required format, with findings located against the component and, where relevant, against a persistent corrosion monitoring location so trends stay continuous between campaigns
Raw data in the instrument-native format plus an open export, so the dataset outlives any single supplier relationship
The procedure revision, technician certification state and instrument calibration status applicable at the time of examination
Where a finding affects continued service, the specific code clause governing the acceptance decision
