PROBLEM TO BE SOLVED: To provide a re-liquefier of a liquefaction gas carrier capable of optimizing a processing capacity.SOLUTION: Boil-off gas of liquid gas loaded into a cargo tank 12 of a liquefaction gas carrier is compressed by a gas compressor 14 and supplied to a marine engine as fuel gas. The compressed boil-off gas which is not used as the fuel gas is re-liquefied by a re-liquefier 16 and a liquid component separated by a separator 20 is recovered to the cargo tank 12. The processing capacity of the re-liquefier 16 is set to a value corresponding to the fuel gas consumption of the marine engine at a vessel speed in which the appearance frequency of the vessel speed becomes a specified value. The surplus boil-off gas, which cannot be processed by the re-liquefier 16 in the boil-off gas that is not used as gas fuel, is incinerated in fuel gas firing equipment 18.

    【課題】処理容量が最適化された液化ガス運搬船用の再液化装置を提供する。【解決手段】液化ガス運搬船のカーゴタンク12に積載された液化ガスのボイルオフガスをガスコンプレッサ14で加圧し、舶用機関へ燃料ガスとして供給する。燃料ガスとして使用されない加圧ボイルオフガスを再液化装置16で再液化し、セパレータ20で分離された液体成分をカーゴタンク12に回収する。再液化装置16の処理容量を、船速の出現頻度が所定値となる船速での舶用機関の燃料ガス消費量に対応する値に設定する。ガス燃料として使用されないボイルオフガスのうち再液化装置16で処理できない余剰ボイルオフガスをガス燃焼装置18で焼却する。【選択図】図1
