Abstract: As a clean energy, liquefied natural gas plays an important role in adjusting the energy structure and building a clean, low-carbon and efficient energy system. Based on Cruise software, the gas-powered simulation model of 4×2 liquefied natural gas carrier is established by selecting appropriate parameters of powertrain, gas supply system and transmission system, to analyze the dynamic economy of liquefied natural gas transporter, which provides an important basis for the design and development of liquefied natural gas products in this paper.
