PT. Sarihusada Generasi Mahardhika uses natural gas in the form of Compressed Natural Gas (CNG) for the heating process of boilers by producing steam that is used for production. The damage caused by CNG fires varies, ranging from minor damage to the destruction of the installations and injuries to deaths in humans. Mitigation is action taken to reduce the impact of an unwanted event before the event occurs, through mitigation efforts that can be carried out through the control of hazard sources and risk-based exposed objects. Safe risk value changes can be achieved after applying appropriate mitigation techniques. Research relates to mitigation techniques that have been developed through reducing risk directly but do not look at the relationship with the risk distribution that exists. One effort can be made by conducting risk analysis and determining mitigation based on risk distribution. Analysis of the calculation of risk values using the fault tree method and consequential calculation is done through the ALOHA simulation model approach. The mitigation technique is determined based on the risk distribution contained in the ALOHA simulation which reflects the level of risk in the object exposed around the source of the hazard. Leaks on CNG tanks were calculated using leaky hole diameters of 1 cm, 5 cm, and 7.6 cm. The probability value in the largest CNG fire scenario is found in CNG tank leaks with a probability value of 6.56 e-05 events/year. At 1 cm leaky hole diameter has a risk value in the red zone 6.56 e-05, orange zone 0 and yellow zone 0. The diameter of the leaking hole 5 cm has a risk value in the red zone 19.68 e-05, orange zone 131,2 e-05and yellow zone 6,56 e-05. At 7.6 cm leaky hole diameter has a risk value in the red zone 354.24 e-05, orange zone 196.8 e-05 and yellow zone 6.56 e-05. The mitigation technique is determined based on a pessimistic assumption if the CNG safety system cannot run properly and does not change the existing plant. [ABSTRACT FROM AUTHOR] |
