Liquefied natural gas (LNG) terminals ensure the production, storage, and transportation of LNG. Therefore, it assembles critical equipment that can cause hazards to personnel, assets, and the environment. This paper presents a risk assessment for an LNG storage tank release in an LNG terminal. Risk assessment was conducted by applying a HAZOP study, Bowtie analysis, fault tree analysis, and ALOHA (Areal Locations of Hazardous Atmospheres) simulation. The results were to identify causes, consequences, and safeguards of hazards related to over and under pressure in an LNG storage tank. Moreover, a bowtie analysis was established for LNG loss of containment (LOC) from flammable liquids storage tanks. In addition, a fault tree analysis was presented to identify the causes of tank failure considering pressure hazards. Finally, the consequences of LNG released from the storage tank are simulated using the ALOHA software
