To provide a method for transition method for liquefied gas and a transition method for boil-off gas capable of suppressing enlargement of a generator or an increase in number as well as reducing personnel necessary for operation of a power generator facility of a vessel during standby.SOLUTION: A transition method for liquefied gas is the transition method for the liquefied gas using a vessel provided with a tank for storing the liquefied gas and includes: a process for lowering temperature or pressure inside the tank toward a second target value which is lower than a first target value of the temperature or the pressure necessary when reliquefying the boil-off gas generated by having the liquefied gas gassified by operating a reliquefying device of the vessel by power supply from an outside power system; and a step for navigating the vessel to carry the liquefied gas and supplying the liquefied gas inside the tank to an outside supply source.SELECTED DRAWING: Figure 5
【課題】発電機の大型化や台数増加を抑えるとともに、待機中に船舶の発電設備を運転するために必要な人員を削減することができる液化ガスの移載方法、ボイルオフガスの移載方法を提供する。【解決手段】液化ガスの移載方法は、液化ガスを収容するタンクを備えた船舶を用いた液化ガスの移載方法であって、外部の電力系統からの電力供給によって前記船舶の再液化装置を運転することで、前記液化ガスが気化して生成されたボイルオフガスを再液化させる際に必要になる温度又は圧力の第一の目標値よりも低い第二の目標値に向けて、前記タンク内の温度又は圧力を低下させる工程と、前記船舶を航行して前記液化ガスを運搬し、前記タンク内の前記液化ガスを外部の供給先に供給する工程と、を含む。【選択図】図5
