Fire Impact Modelling on Human Due to Leakage of Storage Tank at LNG Terminal Using Fire Dynamics Simulator

Abstract

The increasing demand for Liquified Natural Gas (LNG) is directly proportional to the risk of LNG Facilities. One of the risks is fire due to leakage of the LNG storage tank at the LNG terminal. This study aims to predict the impact of jet fire on humans due to leaks of LNG storage tanks using Fire Dynamic Simulator and predict the probability of injury or death due to the accident. This simulation uses LNG storage tank capacity as variations including primary data obtained from field surveys. The first results are Hazard and Operability (HAZOP) analysis which found that the cause of the leak was caused by 3 aspects: overpressure, temperature, and corrosion. In addition, the simulation results show 21 deaths due to thermal radiation that occurred in the 20000 m3 storage tank, with a radius of 250 m from the LNG storage tank and a radiation dose of 9,787,223 W4/3sm−8/ 3. Finally, it is recommended that the LNG storage tank be 1200 m3. have a minimum radius of 80 m from the office or housing while the LNG storage tanks of 7500 m3 and 20000 m3 must be 185 m and 250 m apart from the residence.
