PROBLEM TO BE SOLVED: To provide a movable 13A gas supply method without defects found in a conventional supply facility wherein many apparatus for heating value adjustment and odorization are required, and control and operation in LNG charging while carrying out the heating value adjustment and odorization are complicated, and moreover the cost is naturally high as the whole apparatus. SOLUTION: The method of vaporizing LNG (liquefied natural gas) from a movable low-temperature LNG storage vessel to supply 13A gas to a required area comprises (1) a process for charging the low-temperature LNG storage vessel with LNG, (2) a process for exhausting methane gas with a low boiling point from the low-temperature LNG storage vessel to adjust the calorie of LNG in the low-temperature LNG storage vessel, (3) a process for vaporizing the LNG from the low-temperature LNG storage vessel by an evaporator, and (4) a process for mixing gas mainly composed of methane containing an odorant, in NG (vaporized natural gas) to obtain supply gas.
