Quantitative risk analysis is part of risk assesment which applied detail and aim to assess risk in oil and gas industry. Risk can be assessed by multiplying likelihood of failure and consequence of failure. Piping system has a main role in oil and gas industry but can cause a high risk if leak. Therefore, quantitative risk analysis has to be applied into piping system.<p> <br /> <br /> <br /> <br /> <br /> The methodology of quantitative analysis for piping system consists of 5 steps as follows: analysis data collection, calculation of release rate/mass, type, and duration, calculation of likelihood of failure (LoF), calculation of consequence of failure (CoF), and determination of risk using risk matrix. LoF is estimated by multiplying generic failure frequency, equipmet modification factor, and Process Safety Management (PSM) modification factor. CoF consists of flammable, toxic, environment, and business interruption consequence.<p> <br /> <br /> <br /> <br /> <br /> The case study is 16 piping of process gas, compression gas, export and metering gas system in MoGPU Hang Tuah Platform. The result of quantitative analysis is 5 piping categorized as medium-high risk and the other 11 piping as medium risk. The damage mechanisms that occur in the piping are sand erosion, CO2 corrosion, corrosion under insulation, SSC, dan HIC/SOHIC.
