What pipeline inspection involves

Pipeline inspection establishes the condition of a line along its length, combining in-line inspection where the line is piggable with direct assessment where it is not, and verifying both against excavation findings.

Scope of work

In-line inspection data review and dig prioritisation from MFL, ultrasonic and crack-detection runs
Guided wave screening of cased crossings and inaccessible sections
Dig verification with ultrasonic wall measurement and magnetic particle crack examination
Coating and cathodic protection survey interpretation
Girth weld examination by automated ultrasonic testing or radiography on new construction

Governing codes

ASME B31.4 and B31.8 for design and operation, B31.8S for integrity management, API 1104 for welding, and the applicable regulator's integrity management rule.

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.

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
