Keywords: Risk based work selection; Progressive failure approach; Final failure approach; Risk based in spection; Work optimization; Structural anomaly Abstract Risk based Work Selection Method (RBWS) helps asset owners and operators to identify, prioritize and optimize maintenance activities taking into consideration the Safety, Health, Environmental and Economic consequences. There are two approaches to assess the risk associated with a structural component anomaly: Final failure & progressive failure approach. It has always been a challenge for an integrity engineer to select an appropriate approach to decide the risk and mitigation plan for a structural anomaly. This paper in-detail discusses the applicability of these approaches for different structural members based on their functionality and criticality in the overall structural arrangement and help the engineers make a judicious decision in planning the maintenance activities without compromising the integrity of structure. © 2025 The Authors.

Introduction For long term reliability of processing facilities, schedule turnarounds are planned, where a unit or entire facility is shutdown to perform major maintenance as well as inspection. These planned events also provide the owners and operators with an opportunity to upgrade the process & improve production efficiency. Incompetent and inconsistent methods of risk screening and selecting maintenance work can lead to missed opportunities for improvement and a poor return on investment. Risk based work selection method is systematic process for prioritizing maintenance work using risk to screen each work items.
