摘要

Conventional risk assessment methodologies are not able to quantify dynamic changes in process. To bridge this gap, dynamic operational risk assessment methodology provides a mean to measure operational risk due to dynamic behavior of process. In dynamic risk assessment, ageing of equipment/component is an important time-dependent criterion that can increase equipment/component's failure rate, which hasn't been addressed in previous researches. In this paper, ageing factors are integrated in the framework of dynamic operational risk assessment methodology to analyze the effect of system degraded behavior on dynamic risk. A case study on commonly used oil/gas separators on offshore plants illustrates this model.
