A vaporizer of a cargo system for an LNG ship is provided to separately install an evaporator and a forced evaporator in a single shell and selectively use the evaporator and the forced evaporator depending on necessity. A vaporizer of a cargo system for an LNG ship includes a first partition wall(1), a second partition wall(5), a shell(8), first and second evaporation tubes(9,10), first and second supply valves(11,12), first and second discharge valves(13,14), and an equalizing valve(15). The first partition wall divides the shall into first, second and third chambers(2,3,4). The first and second chambers are divided by the second partition wall into an evaporation chamber(6) and a forced evaporation chamber(7) of the shell. The first and second evaporation tubes are in communication with the evaporation chamber and the forced evaporation chamber. The first and second supply valves are installed at the evaporation chamber and the forced evaporation chamber to supply the LNG. The first and second discharge valves are installed at the evaporation chamber and the forced evaporation chamber to discharge the liquefied LNG. The equalizing valve is installed at the evaporation chamber and the forced evaporation chamber to make the pressure thereof uniform.
