What pipeline inspection actually covers

Assets in scope: transmission and gathering lines, girth and seam welds, pump and compressor stations, road and rail crossings, river crossings, and above-ground installations.

Damage mechanisms that drive the inspection plan

External corrosion under disbonded coating and at holidays; internal corrosion at low points and water accumulation; stress corrosion cracking, both high and near-neutral pH; manufacturing defects in older seam welds; third-party mechanical damage; and geotechnical strain in unstable ground.

Methods applied

In-line inspection using MFL, ultrasonic and crack-detection tools; guided wave for cased and inaccessible sections; direct assessment excavation with ultrasonic and magnetic particle at the dig; close interval potential survey and DCVG for coating and cathodic protection condition; and automated ultrasonic testing on new girth welds.

Governing codes and standards

API 1104 for girth welding, ASME B31.4 and B31.8 for design and operation, ASME B31.8S for integrity management, NACE/AMPP standards for corrosion control, and the applicable regulator's integrity management requirements.

What makes this sector different

Integrity decisions rest on fusing in-line inspection data with cathodic protection and coating survey data and with dig verification. The recurring failure is treating each dataset separately, which produces dig programmes that verify the tool rather than manage the risk.

The San Francisco asset base

The San Francisco Bay Area hosts Chevron's corporate headquarters in San Ramon, Chevron Richmond Refinery (245,000 bpd), Phillips 66 Rodeo (now being converted to renewable diesel), Marathon Martinez (the largest US renewable-fuels conversion project), and Valero Benicia. The transition from petroleum to renewable diesel — at Marathon Martinez (48,000 bpd) and Phillips 66 Rodeo (50,000 bpd) — requires extensive pressure-equipment re-qualification under new feedstock conditions. CARB low-carbon-fuel standards, BAAQMD rule 12-16 refinery emission limits, and California AB 1647 inspection requirements drive systematic digital twin adoption.

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.
