NCS-PIPELINE-DEMO-T17 — Coating Passport

In-line inspection campaign on a 762 mm sour-gas trunk pipeline (commissioned 2003) — TLC corrosion at 12 o'clock, pitting at sag bend, FBE coating disbondment. Severity calibrated to DNV-RP-F101 + B31G fitness-for-service criteria. Same canonical CoatingPassport as our maritime + offshore-wind demos.

Findings detail

corrosion

confidence 92%1287 framesimg-quality 84%severe

General corrosion with 58% wall-thickness loss over a 1.2 m × 0.4 m area at top-of-line. Consistent with TLC (top-of-line corrosion) signature from sour-gas service.

Location: KP 8+420, 12 o'clock orientation (8420, 0, 0)

Recommended action: DNV-RP-F101 / B31G fitness-for-service assessment; consider pressure derating until repair scheduled; plan composite-wrap reinforcement at next inhibitor campaign.

pitting

confidence 87%412 framesimg-quality 81%moderate

Pitting cluster at low point, max depth 3.2 mm. Consistent with water-accumulation at sag bend.

Location: KP 11+200, 6 o'clock (bottom) (11200, 0, 0)

Recommended action: UT thickness confirmation at next dive; monitor sag-bend pigging strategy.

coating breakdown

confidence 81%198 framesimg-quality 76%moderate

FBE (fusion-bonded epoxy) coating disbondment over a 0.5 m circumferential band. Consistent with prior pipeline movement; cathodic-protection compensation adequate per UT.

Location: KP 4+150, full circumference, 0.5 m length (4150, 0, 0)

Recommended action: Re-inspection within 24 months; consider in-situ patch coating if disbondment grows >0.8 m circumferentially.

weld defect

confidence 74%89 framesimg-quality 72%minor

Single inclusion indication at girth-weld root, ~3 mm. Within ISO 19232 / API 1104 acceptance for in-service inspection.

Location: KP 6+885 girth weld (6885, 0, 0)

Recommended action: No action this cycle; document for trending.
