A Storage Tank is an important piece of equipment for oil exploration and exploitation that functions as a large amount of fluid storage. Storage Tanks are very susceptible to corrosion because the material used in making this Storage Tank is made of steel. Therefore, the Indonesian government applies a regulation regarding the determination of the remaining service life of equipment listed in Ministerial Regulation No. 32 of 2021; it is necessary for Residual Life Assessment (RLA) to prevent holes and structural failures of the tank. The method used is the Visual Examination of UT Thickness. Then the thickness value is used to analyze and calculate the required thickness (Treq), Corrosion Rate (CR), Maximum Filled Height (MFH) and the remaining life (Remaining Life) of the Storage Tank. The results of the RLA found that the remaining service life of the Storage Tank was 20 years with a corrosion rate of 0.034 mm/year, while the UT thickness measurement found the lowest component value on the roof section of 5.76 mm. No significant anomalies were found during the inspection, which might affect the storage tank's ability to continue operations safely. However, it is recommended to maintain the condition of the storage tank so that it remains in its service function.
