Zusammenfassung:To provide an LNG satellite facility capable of starting operation of a power generation device and continuing the operation even if power supply from a power system is stopped for a long time.SOLUTION: The present invention relates to an LNG satellite facility comprising a fuel gas supply unit 30 for supplying a fuel gas containing a natural gas obtained by vaporizing LNG to a power generation device 11, and the power generation device 11. The LNG satellite facility comprises an auxiliary power supply device 20 which includes a power storage unit 21 and is capable of supplying power for activating the power generation device 11 to the power generation device 11. The fuel gas supply unit 30 includes a vaporizing section 36 for vaporizing LNG and a heat supply section 31 for supplying heat to the vaporizing section 36. A power supply switching device 8 supplies power being supplied from an AC line 2 to the vaporizing section 36 in a case that power is being supplied from at least one of a power system 1 and the power generation device 11 to the AC line 2, and supplies power being supplied from the auxiliary power supply device 20 to the vaporizing section 36 in a case that power is not being supplied from both the power system 1 and the power generation device 11 to the AC line 2.SELECTED DRAWING: Figure 1 【課題】電力系統からの電力供給の停止が長時間になっても、発電装置の運転を開始してその運転を継続できるLNGサテライト設備を提供する。【解決手段】LNGを気化して得られる天然ガスを含む燃料ガスを発電装置11に供給する燃料ガス供給部30と、発電装置11とを備えるLNGサテライト設備であって、蓄電部21を有し、発電装置11を起動するための電力を発電装置11に供給できる補助電源装置20を備え、燃料ガス供給部30は、LNGを気化する気化部36と、熱を気化部36に供給する熱供給部31とを有し、電源切替装置8は、交流線2に電力系統1及び発電装置11の少なくとも一方から電力が供給されている場合、交流線2から供給される電力を気化部36に供給し、交流線2に電力系統1及び発電装置11の両方から電力が供給されていない場合、補助電源装置20から供給される電力を気化部36に供給する。【選択図】図1
