What oil and gas inspection actually covers

Assets in scope: pressure vessels and separators, process piping and flowlines, aboveground storage tanks, heat exchangers, fired heaters, wellheads and Christmas trees, and gathering and transmission pipelines.

Damage mechanisms that drive the inspection plan

Sulfidation and naphthenic acid corrosion at temperature; wet H2S cracking including HIC and SOHIC in sour service; CO2 corrosion and top-of-line corrosion in wet gas; microbiologically influenced corrosion in dead legs and low points; corrosion under insulation; and erosion-corrosion at elbows and reducers.

Methods applied

Ultrasonic thickness measurement at corrosion monitoring locations, phased array and TOFD for weld examination, radiography including profile radiography for small-bore and insulated lines, magnetic particle and penetrant for surface examination, guided wave for screening inaccessible runs, and MFL for tank floors.

Governing codes and standards

API 510 for pressure vessels, API 570 for piping, API 653 for storage tanks, API 580 and 581 for risk-based inspection, API 579 for fitness-for-service, API RP 571 for damage mechanisms, and ASME Section V and Section VIII throughout.

What makes this sector different

Inspection intervals derive from measured corrosion rate and remaining life rather than a fixed calendar, which makes the quality of the thickness data decisive. Readings that cannot be proven to come from the same corrosion monitoring location cannot support a defensible interval.

The Los Angeles asset base

Los Angeles is the historical heart of California refining, with Marathon Carson (formerly Tesoro/Andeavor — the largest refinery on the West Coast at 363,000 bpd), Phillips 66 Wilmington/Carson, Valero Wilmington, Chevron El Segundo, and Marathon Wilmington collectively processing over 1.4 million bpd of crude. The Ports of Los Angeles and Long Beach handle massive crude and product imports, and the SoCalGas underground gas-storage network (Aliso Canyon, Honor Rancho, Playa del Rey) requires rigorous well-integrity monitoring under CalGEM oversight after the 2015 Aliso Canyon leak. California's AB 1647 refinery-monitoring requirements, CARB low-carbon-fuel standards, and South Coast AQMD rule 1180 create a compliance environment ideally suited to digital twin reporting.

How the work is controlled

Every examination carries its own evidence chain: the technician's certification for the method and level under ASNT SNT-TC-1A or ISO 9712, current on the day of inspection; the calibration status of instruments, probes, wedges and reference blocks, traceable under ISO 17025; and the revision of the procedure and technique sheet in force at the time. An ASNT NDT Level III reviews and signs the final disposition. That bundle is what a client or accreditation audit examines, and it is recorded as the work happens rather than assembled afterwards.
