にする。First, BOG is filled from the BOG line 20 into the cold insulation layer 14 between the inner and outer tanks 12 and 13 through the BOG filling line 21. At this time, there is a temperature difference between nighttime and daytime, and in the daytime, since the outer tub 13 absorbs heat in direct sunlight, the BOG pressure between the inner and outer tubs 12 and 13 is:
It changes drastically between day and night. Therefore, for example, a maximum pressure value Pmax between the inner and outer tanks 12 and 13 in the daytime is set, and a pressure value 500 mmAq lower than that is set as Pmin, and the maximum and minimum pressure values Pmax and Pmin are determined by the pressure compensator 25. When the BOG pressure between the inner and outer tanks 12 and 13 falls below the minimum pressure value Pmin at night, the pressure control valve 23 is controlled to transfer the BOG from the BOG filling line 21 to the inner and outer tanks 12 and 13.
13 to prevent the pressure from exceeding the minimum pressure value Pmin, and when the pressure exceeds the maximum pressure value Pmax during the daytime in summer or the like, the BOG between the inner and outer tanks 12 and 13 is discharged to the atmosphere.
Alternatively, if the pressure between the inner and outer tanks 12 and 13 is higher than the BOG line 20, the inner or outer tank 1 may be returned to the BOG line 20 via the pressure control valve 23 or may be caused to flow to another line.
The pressure between 2 and 13 is reduced below the maximum pressure value Pmax.

This makes it possible to substantially reduce the amount of the used gas such as N 2 to zero.
