Title (EN) LIQUEFIED GAS FUEL SUPPLY SYSTEM
(FR) DISPOSITIF D'ALIMENTATION EN COMBUSTIBLE GAZEUX LIQUÉFIÉ
(JA) 液化ガス燃料供給システム
Abstract:
(EN) Through a fuel gas supply pipe 20, a boil-off gas (NBOG) naturally generated from liquefied gas stored in a cargo tank 14 is supplied to a main machine 12 as a fuel gas. The liquefied gas in the cargo tank 14 is pumped up by means of a liquid pump 34 and is forcibly vaporized by means of a forced vaporizer 36, so that the resultant gas can be supplied to the main machine 12 as a fuel gas. Of the fuel gas supplied to the main machine 12, a surplus gas is recovered via a gas recovery pipe 26 and reliquefied through a BOG recovery device 22 and an expansion valve 28 for return to the cargo tank 14. By operating the forced vaporizer 36 and a reliquefying means simultaneously, the settable range of a vessel speed is expanded.
(FR) Par l'intermédiaire d'un tuyau d'alimentation en gaz combustible (20), un gaz d'évaporation (NBOG) généré naturellement à partir de gaz liquéfié stocké dans une citerne à cargaisons (14) est fourni à une machine principale (12) sous la forme de gaz combustible. Le gaz liquéfié dans la citerne à cargaisons (14) est pompé au moyen d'une pompe à liquide (34) et est vaporisé de manière forcée au moyen d'un vaporisateur forcé (36), de sorte que le gaz obtenu peut être fourni à la machine principale (12) sous la forme d'un gaz combustible. Parmi le gaz combustible fourni à la machine principale (12), un surplus de gaz est récupéré par l'intermédiaire d'un tuyau de récupération de gaz (26) et re-liquéfié par l'intermédiaire d'un dispositif de récupération de BOG (22) et d'un détendeur (28) pour son retour vers la citerne à cargaisons (14). En actionnant simultanément le vaporisateur forcé (36) et un moyen de re-liquéfaction, la plage de réglage d'une vitesse de navire est étendue.
(JA) 燃料ガス供給管20を通して、貨物タンク14内に貯留された液化ガスから自然発生するボイルオフガス(NBOG)を燃料ガスとして主機12に供給する。貨物タンク14内の液化ガスを液ポンプ34で汲み上げ、強制気化器36で強制気化させて燃料ガスとして主機12に供給可能にする。主機12に供給される燃料ガスのうち余剰なガスを、ガス回収管26を介して回収し、BOG回収装置22および膨張弁28を通して再液化して貨物タンク14へ戻す。強制気化器36と再液化手段を同時に運転することで、設定可能な船速の範囲を拡大する。
