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 Seattle asset base
Seattle is the headquarters of Boeing Commercial Airplanes (Everett 737/747/767/777/787 fabrication), Phillips 66 Ferndale Refinery (105,000 bpd), Andeavor/Marathon Anacortes Refinery (120,000 bpd), and BP Cherry Point Refinery (236,000 bpd) at the strategic Strait of Juan de Fuca corridor. Trans Mountain Pipeline's Westridge marine terminal and the Olympic Pipeline product distribution network drive PHMSA integrity-management work. The combination of Boeing's NAS 410 aerospace NDT (composites and metallics), Cascadia subduction-zone seismic risk, and the maritime corrosion environment make Seattle a uniquely diverse digital twin market.
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.
