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