Abstract: Most of the transportation industry is still dependent on fossil fuels. The use of fuel oil in the transportation industry has a negative impact on environmental pollution because fuel oil contains CO2. With the increasing use of fuel oil and environmental pollution problems, Compressed Natural Gas (CNG) is now being developed in the transportation industry. When compared to fuel oils such as gasoline, diesel, and Liquified Petroleum Gas (LPG), CNG emits less harmful gas during combustion. CNG distribution requires a storage device, namely a buffer storage tank which is a closed vessel to accommodate liquids and gases with different temperatures and pressures according to environmental conditions. Buffer storage tanks have a very large risk of accidents including leaks that pose a hazard of fire, explosion, and environmental pollution, which has an impact on technical and financial aspects. Seeing the risks posed by the buffer storage tank, it is necessary to take precautions, inspections, and maintenance to minimize the risk of accidents. The results are the Probability of Failure value based on Art was 1, Leakage Risk Assessment was 247.87 ft2, and Economic Consequence was $199,514.04. Based on the results of risk analysis referring to API RBI 2008 for CNG buffer storage tanks, it means that leakage consequences are 1B (low risk) and the risk value for economic consequences is 1C (medium). The remaining life of the CNG buffer storage tank shell section is 10.14 years, and that of the head section is 10.42 years. This research is expected to be able to produce an appropriate inspection scheduling decision model for CNG buffer storage tanks and recommendations for preventive actions based on leakage risk and financial aspects.
