LNG has proven to be a green enegy source and reliable for environmentally, it's combustion residue produces much cleaner pollutants than other fossil fuels. The Ministry of MEMR shows that the increasing demand for national electricity reaches 7.5% each year. Mini LNG carrier is an alternative solution for distribution liquid natural gas to archipelago areas with an operational cost effectiveness challenge. Power plants located in Bali and Nusa Tenggara Island are used as a case study. The aim of this study is to calculate LNG distribution using mini LNG carriers, estimate the operational cost in each power plants and risk assessment. The capacity of vessel and power plants set as the constraint, LCT non-conventional as mini LNG carrier carry out 32 ISO Tank 20ft. Hence its is need 26 mini LNG carrier to supply power plant in Bali and Nusa Tenggara as scenario 1, while 7 mini LNG carrier have to provided to supply power plant in Bali and Lombok as scenario 2. Scenario 1 is inefficient because it requires high investment and operational aspects. The final risk assessment based on hazard analysis due to hydrocarbon handling an F-N curve was found to be in ALARP compared to acceptance criteria.
