As a preventive action, government of Indonesia had issued a regulation that obligate every Oil and Gas Company to conduct a technical inspection of storage tank with Time-Based or Risk-Based Method. Time Based Inspection often results in ineffective inspections method or excessive inspections interval, while Risk-Based Inspection is more effective and efficient. This study aims to determine inspection plan of Crude and Refined Oil Storage Tank in Indonesia Refinery Plant using Risk Based Inspection method. There are 3 damage mechanisms defined in shell of Storage Tank: Atmospheric Corrosion, General Corrosion, and Corrosion under Insulation. Risk analysis calculation using defined damage and technical data collected, shows all Storage Tank which being studied belong to medium risk category. Inspection method suggested were visual inspection and UT thickness/scanning, while inspection interval can be extended to 10 years. Based on this study, implementation of RBI will benefit refinery plant with more effective and efficient inspection method.
