To provide a liquefaction gas fuel supply system capable of stably supplying fuel gas stored in a gas holder (tank) as fuel for main equipment.SOLUTION: The liquefaction gas is stored in a cargo tank 14. A high pressure gas compressor 22 is provided for compressing boil-off gas (BOG) in the cargo tank 14. The gas compressed by the high pressure gas compressor 22 is supplied to main equipment 12 capable of gas firing as fuel via a main equipment gas supply pipe 24. The gas compressed by the high pressure gas compressor 22 can be stored in a gas holder 28. The gas stored in the gas holder 28 is recycled to the high pressure gas compressor 22 via a return pipe 30, so that it can be recompressed.SELECTED DRAWING: Figure 1
【課題】ガスホルダ(タンク)内に貯蔵される燃料ガスを安定的に主機等の燃料として供給可能な液化ガス燃料供給システムを提供する。【解決手段】貨物タンク14に液化ガスを貯蔵する。貨物タンク14内のボイルオフガス(BOG)を圧縮する高圧ガス圧縮機22を設ける。高圧ガス圧縮機22で圧縮されたガスをガス焚き可能な主機12に燃料として主機ガス供給管24を介して供給する。ガスホルダ28に高圧ガス圧縮機22で圧縮されたガスを貯留可能とする。ガスホルダ28に貯留されたガスを、戻り管30を介して高圧ガス圧縮機22に再循環させて再圧縮可能とする。【選択図】図1
