Risk Based Inspection (RBI) is a risk assessment and management process that is focused on loss of containment of pressurized equipment in processing / transportation facilities, due to material deterioration / degradation. These risks are managed primarily through threat identification, inspection, monitoring and mitigation measures. Risk Based Inspection (RBI) process is focused on maintaining the mechanical integrity of high pressure pipelines and minimizing the risk of loss of containment due to deterioration. Frequency of inspection & monitoring activities are fixed in cost effective way which based on the risk ranking.
This paper discusses the development, implementation and maintaining a risk-based inspection (RBI) program for high pressure long petroleum pipelines. It provides guidance to operators of pressure-containing pipelines for developing and implementing an inspection program. This technical paper includes means for assessing an inspection program and its plan. The approach emphasizes safe and reliable operation through risk-prioritized inspection and monitoring program. This also includes practical implementation case study of Wolrd’s longest heated crude oil pipeline operated and maintained by M/s Cairn India Limited.
