The present invention relates to a boil-off gas reliquefaction system and a ship. The boil-off gas reliquefaction system includes: a boil-off gas compressor for compressing, in multi-stages, boil-off gas generated in a liquefied gas storage tank and supplying the compressed boil-off gas to a consumer; a boil-off gas heat exchanger for performing heat exchange between boil off gas compressed in the boil-off gas compressor and boil-off gas introduced into the boil-off gas compressor; a decompression valve for decompressing the boil-off gas compressed in the boil-off gas compressor and then heat-exchanged in the boil-off gas heat exchanger; and a gas-liquid separator for performing gas-liquid separation on the boil-off gas decompressed in the decompression valve. Lubricant used in the boil-off gas compressor of a high pressure stage is mixed with boil-off gas to be introduced into the boil-off gas heat exchanger. The boil-off gas reliquefaction system further includes a high-temperature boil-off gas transfer line configured to transfer high-temperature boil-off gas discharged from the boil-off gas heat exchanger to a low pressure consumer upstream of the decompression valve, when high-pressure boil-off gas compressed in the boil-off gas compressor is injected into the boil-off gas heat exchanger to remove the lubricant introduced into the boil-off gas heat exchanger.
