Abstract
In current work the security of chemical facilities is addressed with regard to the elevated terrorist threat due to recent wave of terrorist attacks. Security Vulnerability Assessment using the ANSI/API Standard 780 methodology is conducted. The methodology is applied on an arbitrarily selected oil refinery in Europe as defined in a case study. The facility is characterised in terms of hazards and critical assets. In the course of the assessment 5 attack scenarios are developed. Forensic data about adversary weaponry and capabilities is collected. Vulnerabilities of the selected oil refinery are revealed. The consequences of the formulated scenarios are assessed based on the blast effects of probable improvised explosive devices (IEDs). The blast waves produced by IEDs are simulated in CONWEP© software. The ‘overpressure vs range’ and ‘penetration vs range’ graphs are extracted as a result of the simulation. Afterwards, the escalation thresholds with respect to different types of equipment are applied in order to verify further knock-on effects. Moreover, several overpressure values corresponding to catastrophic rupture, steel support breakage, deformation of vessel are employed in order to estimate the impact zones. Injuries, probable fatalities and glass wounds stand-off zones are estimated. As for human injuries and structural damage, probit analysis is carried out and a percentage of exposed people and buildings is evaluated. Finally, a set of security countermeasures with regard to uncovered vulnerabilities is proposed.
