Techno-economic and supply chain model of a small-scale LNG for BMPP in Sambelia

Abstract This paper addresses a method for creating the supply chain model of liquefied natural gas (LNG) to a barge-mounted power plant (BMPP) of 30 MW in Sambelia. This paper conducts the supply chain using a landing craft tank (LCT) ship as the LNG carrier, equipped with a specific principal dimension, and an ISO tank as the LNG storage facility. The use of LCT has the advantage of being able to sail in coastal areas and can be converted using existing ships. This comprehensive techno-economic assessment consists of calculating the LNG demands for the BMPP, the arrangement of ISO containerized tank stacking in the LCT, and identifying the LNG terminal facilities. Moreover, the research points for a future LNG economy are highlighted; cost-effective production and utilization solutions for enhancing the feasibility of LNG. The Landing Craft Tank (LCT), a vessel with a load capacity of 32 container tanks (20 ft) and a volume of 20.38 m 3 , distributes LNG to BMPP Sambelia. The economic analysis of LNG distribution patterns from Benoa LNG Terminal to BMPP 30 MW Sambelia, using LCT ships with FSRU (Floating Storage and Regasification Unit) receiver terminals, reveals that at a margin of $2.2, the most optimal option has an IRR of 11.6%, a payback period of 5.7, and an ROI of 17.41%.
