IChemE - Creeping Change Types, Risks and Detection

Creeping change are changes in process conditions or external conditions that take place slowly over an extended time period. This change can be undetected until an incident occurs or a plant becomes inoperable. This talk is an overview of creeping change types, risks and detection, drawing on real-life examples. Case studies include the San Bruno Gas Pipeline Explosion in the US as well as three cases from the presenter’s career: an offshore NGL leak, an onshore fractionation train upset and a wellhead platform that became inoperable overnight. Detection techniques for creeping change will be discussed in the webinar.
