Abstract: A pipeline integrity management system was developed based on the theory of dynamic risk assessment in relevance to the unique characteristics of an oil/gas pipeline project. Furthermore, the cycle pattern of continuously updating integrity management was explored. The feasibility of applying integrity management system was then validated against the case with the close connections between a number of small cycles, indicating that the proposed integrity management system can better fulfill the requirements from dynamic management of pipeline safety.

Key words: oil and gas pipeline, dynamic integrity management, dynamic risk assessment
