The purpose of this research was to introduce and describe a model for Fire Quantitative Risk Assessment of in petroleum Storage Tanks. A novel model was designed to determine the risk of a fire occurrence using of Loss Causation and Swiss cheese models. Then, based on FTA, model and its integration with our initial proposed model, the final model was obtained for fire hazard determination in hydrocarbon tanks. The risk level of the hazard was identified using the energy trace and barrier analysis (ETBA). The quantitative fire risk assessment in the tank were carried out in accordance to the International Association of Oil & Gas Producers (IOGP) guideline. Base on the results, 22 risks were identified which 4 of them were unacceptable risks and corrective action was proposed for them. This method is commonly used in conjunction with the safety analysis of the system. This technique was the final part of this research.
