Abstract

Oil and gas industries around the world are subjected to more threats and accidents as they are handling highly hazardous materials Downstream sector faces many challenges as their safety is primarily governed by the societal consequences Detailed mathematical analysis and accident modelling of such scenarios as applied to oil and gas industries are scarce in the literature Quantified risk assessment is therefore mandatory for all petrochemical industries to restrict risk within the permissible limits It is therefore important to develop tools to manage risk efficiently The present study describes the consequence and risk analysis of the selected accident scenarios for a liquid petroleum gas LPG filling station Consequence analysis will give the hazard distances for dispersion and thermal radiations for leakages jet fires and fireballs Risk analysis will give the individual and societal risk due to the selected accident cases of the plant The study is carried out using the software DNV Phast Risk Various consequence scenarios that may arise from the plant such as dispersion jet fires and fireball are studied and the risk are determined in terms of the quantified hazard distances
