Oil & Gas

Vertix’s most extensive sector. Engagements span exploration and production facilities, gathering and transmission pipelines, gas processing plants, LNG terminals, refineries, and petrochemical complexes — the full hydrocarbon value chain. The integrity risk profile is dominated by sulphidation, hydrogen-induced cracking (HIC), naphthenic acid corrosion, amine and caustic stress corrosion cracking, corrosion under insulation (CUI), and erosion-corrosion in high-velocity service. Inspection is performed to ISO and ASME standards and aligned to the API 510, 570, 653, 580, and 579 framework, with the API 571 damage mechanism library used to drive technique selection.

Capabilities deployed:

• Pressure vessel inspections to ASME / API 510 / CSA B51
• Process piping inspections to ASME B31 / API 570 / CSA B51
• Pipeline integrity inspection to CSA Z662 (oil and gas pipeline systems)
• Aboveground storage tank inspections to API 653 (in-service and out-of-service)
• National Board / NBIC in-service inspection of fired pressure equipment and boilers
• Risk-Based Inspection (RBI) programmes to API 580 / 581
• Fitness-for-Service (FFS) assessments to API 579 / ASME FFS-1
• Damage mechanism reviews and Root Cause Failure Analysis to API 571
• Conventional and advanced NDE to ISO and ASME standards — UT, PAUT, GWT, RT, MT, PT, MFL, vacuum-box, drone
• NACE/AMPP-credentialled coating inspection
• IRATA rope access for elevated and confined-space inspection
