A liquefied natural gas (LNG) management system that stores natural gas in a liquefied state in an isothermal storage tank. A modular multi-fueling platform is in fluid communication with the isothermal storage tank. The modular multi-fueling platform includes a LNG conditioning tank, a compressor, a heat exchanger, a heater, plumbing, associated valves, various sensing transmitters, and a programmable logic computer (PLC). Data acquired by the PLC determines actions by the modular multi-fueling platform, including operation of valves, the compressor, etc. The system transfers LNG between the storage tank, the conditioning tank, and a cargo tank (consumer's vehicle tank). The system employs steps of heating and compressing the LNG and boil off gas to maintain the LNG at temperature. The system employs pressure differences for transferring the LNG between tanks.
