Abstract

With the rapid advancement of technology, it is necessary to supply the energy for these technologies. Most of the energy supply in Indonesia comes from the oil and gas industry. The oil and gas industry has much equipment needed to support the business process. Such as pipeline, tank, heat exchanger, heater, etc. The tank is the most widely used equipment in the industry. The tank is used for temporary storage of production. American Petroleum Institute (API) is one of the most commonly used standard in the oil and gas industry worldwide besides the DNV-GL standard. PT. XXX which is a national company engaged in oil and gas also apply the API standard during the installation process of the tank. Because the tank is one of static equipment, the maintenance strategy that can be applied is Risk Based Inspection (RBI). By using RBI, the company will get information based on risk analysis to make inspection plan for equipment. The basis for implementing RBI is Probability of Failure and Consequence of Failure. However, the random scenario of damage must also be considered and calculated. In this final project used Risk Based Inspection method in risk analysis as well as determining the proper maintenance type of each damage factor which become the object of analysis. In this final project, damage factor in this case already being screened is thinning damage factor and external corrosion damage factor possibly happened to Condensate Storage Tank BANG-T-05 that own by PT.X. The following results are obtained the risk value of the Condensate Storage Tank BANG-T-05 is 0.51 ft2/year. Inspection planning for Condensate Storage Tank BANG-T-05 planned at 1,3 years after RBI Date. Which is 29th June 2019. Schedule and inspection method for operation for 10 years, there are: Inspection method for thinning damage factor is at least 5% UT scanning, automated or manual and also Inspection method for external corrosion damage factor at least 60% visual inspection of the exposed area with follow-up by UT, RT or pit gauge as required. The inspection schedule based on RBI analysis is on 29th June, 2019. The results are shorter than the provisions of SKPP Migas, which is every 3 years. The different schedule of inspections can be caused by incomplete data. Damage Factor value after inspection in target date can be lowered by 4,12 factor. So, the new damage factor at plan date after inspection is 7,01.
