Determining reassessment intervals is a vital part of the pipeline integrity management process that has often not received the level of analysis it should to ensure pipeline safety. Defaulting to the maximum reassessment interval allowed by code and not analyzing each unique inspection segment for each pipeline threat can lead to failures and undermine an effective integrity management program. Operators should have a rigorous, documented process in determining and employing reassessment intervals to ensure pipeline integrity and to ensure that changes to the pipeline system and other new information cause a re-evaluation of the reassessment intervals.
