An outlet connection part (17) comprising a liquefied gas supply valve (19), a connection joint (20), and a purge gas supply gas (21) is provided to a liquefied gas supply facility (12) side. An inlet connection part (18) comprising a liquefied gas on-off valve (29) and a connection joint (28) in communication therewith and connected to the connection joint (20) is provided to a ship (11) side. The liquefied gas supply valve (19) is closed to stop the supply of liquefied gas. The purge gas supply gas (21) is opened to supply purging gas to the outlet connection part (17) and the inlet connection part (18). Monitoring is carried out to determine whether liquefied gas has been purged from both connection parts (17, 18). After confirmation that purging has been completed, the liquefied gas on-off valve (29) is closed and the connection of the connection joints (20, 28) is disengaged. |
