- Abstract
- This paper investigates the possible failure modes of an incident of ultrasonic (UT) pig lodged in a Corrosion Resistant Alloy (CRA) clad pipeline during a baseline in-line inspection as part of pre-commissioning pipeline activities. The paper establishes the pipeline integrity following the incident and determines whether it remains fit for the intended service. The paper also discusses the suitability of using UT pigging for in-line re-inspection of the damaged pipeline, the effect of hoop stress due to pipe-wall thinning and the possibility of crack growth. Additionally, the possibility of undetected damage is considered alongside rigorous fatigue crack growth and fracture mechanics assessments of the pipeline to ascertain the pipeline integrity. It was concluded that the probability of the pipeline sustaining flaws exceeding a minimum depth of 1.8 mm is minimal. Due to the robust manufacturing process of the CRA clad pipeline, it was also concluded that the gouges left during the pigging incident do not affect the ability of the clad layer to provide corrosion protection. © 2022 Elsevier Ltd
