Risk based inspection planning
- ARCO Chemical Co., Channelview, TX (United States)
The Refining and Petrochemical Industry has devoted considerable time and effort to develop methodologies for Risk Based Inspection (RBI) over the last several years. RBI is a technique for prioritizing inspection and is designed to focus more attention on safety and reliability on the more critical processes and provide cost savings on the least critical processes. RBI meets the requirements and intent of OSAH 1910.119(j) and Appendix C for fixed equipment. This is a brief overview of the ARCO Chemical approach to RBI in the Gulf Coast area and discusses the incentives for RBI, the components of this RBI technique, and the software approach used to implement RBI. This presentation describes the overall technique used to calculate a priority for each piece of equipment by combining a probability of failure assessment with a degree of hazard assessment. The priority will define a frequency of inspection consistent with ACC and industry standards. Implementation of the technique relies on a software approach which integrates the RBI Planner with ultrasonic thickness software and the plant workorder database.
