Risk Based Design of LNG Regasification Terminal in Kupang

The government of Indonesia has decided to switch fossil fuel to LNG for power plant fuel supply. According to Indonesian Ministry of Energy and Mineral Resources Decree RI No. 13K/13/MEM/2020, the government of Indonesia has decided to switch fossil fuel to LNG for 52 power plants in Indonesia, PLTMG Kupang Peaker is one of them. Currently, there are no facilities for receiving and regasification LNG in Kupang. Therefore, this research will accommodate the design of LNG regasification terminal by utilizing the vacant land in PLTMG Kupang Peaker area. The design is based on NFPA 59A and evaluated through fire risk assessment. In this research, the fire risk assessment consists of identifying hazards with HAZOP studies according to BS IEC 61882 : 2001 standard, frequency analysis through fault tree analysis (FTA) and event tree analysis (ETA), consequences analysis using fire modelling software ALOHA, and risk mapping using f-N curve UK societal risk criteria for process facility. From the risk mapping, there are 4 scenarios that are in the intolerable region. After mitigation using Layer of Protection Analysis (LOPA), the frequency value decreases and the risk for 4 scenarios that previously in the intolerable region can be lowered to the acceptable region.
