Abstract: A system (100) for liquefying a gas comprises a liquid piston gas multistage compressor (2). It can be arranged on-board a liquefied gas carrier for recycling boil-off gas. Such system may be easily adapted or controlled for matching wide requirement ranges for variations of the liquefaction capacity. In addition, at least part of the liquid piston gas multistage compressor can be shared between the gas liquefying system and an extra gas-fed device. Such extra gas-fed device may be in particular a gas-fuelled or hybrid fuel propulsion engine of the vessel.
