<p>PURPOSE:To make it possible to perform continuous running for a long time and reduce failure by making the same kind of heated gas as liquefied gas spout into the liquefied gas. CONSTITUTION:The LNG gas or the like having collected in the top section of a cargo tank 1 is compressed by a gas compressor 3 through a pipe 2 and then heated by a gas heating device 4. A blowoff device 11 for loading navigation is arranged to a position lower than a loading navigation liquid level L1 and a blowoff device 12 for ballast navigation to a position lower than a ballast navigation liquid level L2 in the tank 1. Heated gas is fed to the device 11 through the pipe 13 forked from a pipe 2A and in addition the device 12 through a pipe 14. During loading navigation, a valve 16 opens to blow gas off from the device 11 into the liquefied gas in the tank 1 gasifying the liquefied gas enforcedly. And during ballast navigation, the valve 16 closes and a valve 7 opens to blow gas off from the device 12 into the liquefied gas gasifying the liquefied gas enforcedly.</p> |
