Abstract
Inspection strategy is an important activity in processing plants, and one of the key tools used for such strategy is the risk-based inspection (RBI) methodology. Risk-based inspection is a methodology for optimization of inspection strategy. Based on principle of the risk-based inspection methodology in API 581, the risk assessment for vessels and pipelines in olefins conversion plant is carried out. The main failure modes and damage mechanisms of vessels and pipelines are identified. All vessels and pipelines in this plant are prioritized based on the level of risk. Risk reduction measures and optimal inspection strategy are proposed. This application of risk-based inspection will provide reference for the inspection of the olefins conversion plant.
