Security of chemical facilities has become an issue after terrorist attacks of 9/11 since the hazardous materials involved can cause significant damages in case of a security event like terrorist attacks. Among chemical facilities, oil and gas pipelines can be potential targets for intentional attacks partly due to relatively weaker physical security barriers and partly due to their passage through industrial and populated areas. As a result, the security risk of pipelines needs to be evaluated, and appropriate measures should be allocated to protect the pipelines against intentional attacks. The majority of current methodologies are mostly qualitative or semi-quantitative and thus strongly subjective and biased. In the present study, an innovative security vulnerability assessment methodology is developed based on Discrete-Time Bayesian Networks (DTBN). The DTBN is developed considering the security countermeasures that need to be disabled by an attacker in a given mission time. The consequence analysis and attractiveness assessment are carried out using conventional methodologies developed in previous studies. The security risk is accordingly defined as the product of vulnerability, consequence and relative attractiveness. Dividing an illustrative pipeline in several segments, each with specific operational and environmental characteristics, the developed methodology is applied to calculate and rank order the security risks of the segments. The developed methodology can be applied to security vulnerability assessment of a wide variety of chemical facilities.
