This paper presents the assessment of risk levels of the worker categories on the onshore LNG terminal regasification facility. Quantitative Risk Assessment are applied to evaluate the process and non-process accidental events at Onshore Regasification Unit (ORU) during offloading and normal operation. Individual Risk Per Annum (IRPA) and Potential Loss of Life (PLL) are the parameters to measure the risk for an individual in a specific worker category on the ORU area. Estimation numerical are provided to allow understanding of the risk exposure and fatality amongst the whole worker category or other areas of interest. QRA studies is used to take into account potential releases of hazardous material, estimated frequency of occurrence and consequences. Major Accident Hazard (MAH) are identified by the hazard identification process to identify all incident possibilities which cause to extensive damage to company assets and severe impact to people. Frequency of hazard occurrences is quantified using Event Tree Analysis (ETA) and fire modelling is utilized to represent the consequence. Evaluation against a set of risk acceptance criteria is carried out to the risk level arising from operation of the ORU area. Finally, a set of Safety Operation Procedure (SOP) and Emergency Response Plan (ERP) are developed to ensure the safety operation of the facility.
