To warm up a liquefied gas storage tank on a vessel or on a floating structure, without installing a gas compressor for warming-up or supplying high-temperature gas from the outside.SOLUTION: A boil-off gas treatment system of a vessel or floating structure is configured to supply boil-off gas (BOG) occurring in a liquefied gas storage tank 12 from the liquefied gas storage tank 12 to gas consumption equipment such as a binary fuel heating power generation engine 20 or binary fuel heating boiler 22, through a gas compressor 28, wherein the liquefied gas storage tank is configured to store liquefied gas. On a discharge side of the gas compressor 28, a pipeline 40 is provided for returning gas back into the liquefied gas storage tank 12.SELECTED DRAWING: Figure 7

    【課題】ウォームアップ用のガスコンプレッサを設置したり、外部から高温のガスを供給したりすることなく、船舶上あるいは浮体構造物上において液化ガス貯蔵タンクのウォームアップを行う。【解決手段】船舶または浮体構造物のボイルオフガス処理システムにおいて、液化ガスを貯蔵する液化ガス貯蔵タンク12からガスコンプレッサ28を通して液化ガス貯蔵タンク12内で発生するボイルオフガス(BOG)を2元燃料焚きの発電機関20や2元燃料焚きのボイラ22などのガス消費機器に供給する。ガスコンプレッサ28の吐出側に、液化ガス貯蔵タンク12内にガスを返送する配管40を設ける。【選択図】図7
