しまうという問題があつた。 The above-mentioned known concept for the energy supply of liquefied natural gas tankers can be said to be the most economical at present. However, it is a safety issue to have multiple reliquefaction machines so that if the drive means of one reliquefaction machine fails, the drive means of the other reliquefaction machine will liquefy the vapor from the cargo tank. Complying with regulations is expensive. That is, two reliquefaction machines must be provided, and separate engines and generator sets must be provided to drive these reliquefaction machines, which increases costs. Furthermore, the safety regulations mentioned above require that each reliquefaction machine must be capable of reliquefying the maximum possible amount of liquefied gas that is vaporized. As a result, there was a problem in that equipment costs became increasingly expensive.

is opened and switch 45 is closed, thus
At this time, the sets 13, 14 together with the device 15 supply power to the reliquefaction machine. The valve 42 is partially open, so that some of the steam rising in the load tank 18 is pumped 43 to the additional combustion device 40 of the boiler 11, thus increasing the amount of steam. is made to cover the increased steam consumption of sets 13 and 14.

ことである。 If both sets 13, 14, 16, 17 fail and therefore power is not available to reliquefy the evaporated liquefied gas, the valve 42 is fully opened and the load tank 18 is turned off. All steam generated is combusted in an additional combustion device 40. The three-way valve 52 of the steam supply line 21 is switched to a line 53 extending to the condenser so that the entire amount of steam produced in the boiler 11 is sent to the condenser 23 and condensed. Another possibility is that all the steam produced is connected to the three-way valve 52;
The water is blown directly into the seawater 26 via the pipe 54.
