Abstract
Because the increase of oil demand to fulfil the human needed for daily basis makes the market to use the oil storage tank increasing too. It makes storage tank become one of the critical equipment used in the oil and gas industry. The tank condition should be monitored. It is to make sure that the storage tank always in ready to be operated condition. When the tank was not in ready to be operated condition it can ruin the oil distribution process to the customer. There should be an inspection or maintenance process to control the storage tank condition. The oil storage inspection process commonly done by focused on the tank condition. The inspection commonly done with the time-based inspection. With RBI method that assess into Tank 21 that located in PT.X gresik it can determine the risk ranking of the tank. The risk ranking is used to determine when the inspection should be done for the next inspection. The standart that used to assess the tank with the RBI method is API 581 STD. RBI method determined the equipment based on the risk that the equipment has. There will be a risk ranking from the equipment that has a high-risk level until the equipment that has a low-risk level. The inspection can be done based on the risk that the equipment has. From the RBI calculation to determine the probability of failure and the consequences of failure. From both of them each tank shell course risk will catagorized. The risk should be determined on the RBI date and Planned date. From both of them each tank shell course risk will catagorized. The tank has 6 shells course. So, each tank course shell has different risk, the risk of each shell course around = 0,068m^2/year. After the RBI calculation, the tank shell has Probability of Failure value = 1,43E-04 failure/year. For the consequences of failure value it can be determine as 477,65 m^2. From that calculation the risk can catagorized into 2C. The Inspection planning can be determine based on the damage factor or the risk. From the calculation the isnpection planning date is longer than the planned date which is on 17/10/2022 and 19/10/2022.
