The invention provides a boil-off gas reliquefaction system for a ship. The boil-off gas reliquefaction system includes: a cargo hold provided in a ship and storing liquefied petroleum gas; discharging boil-off gas generated by liquefied petroleum gas from the cargo hold along a gas reliquefaction line and reliquefying the boil-off gas; a compression unit provided in the gas reliquefaction line and receiving the boil-off gas to compress the received boil-off gas; and a condenser provided in the gas reliquefaction line and cooling the boil-off gas compressed by the compression unit, in which the compression unit includes: a first compressor receiving the boil-off gas and compressing the received boil-off gas; and a second compressor that further compresses the boil-off gas compressed by the first compressor and supplies the further compressed boil-off gas to the condenser, and both the first compressor and the second compressor are provided as centrifugal compressors.

    本发明提供一种船舶的蒸发气体再液化系统。蒸发气体再液化系统包括:设置于船舶并储存液化石油气的货舱;沿气体再液化管线,将液化石油气产生的蒸发气体从货舱排出并再液化;设置于气体再液化管线并接收蒸发气体以压缩所接收的蒸发气体的压缩单元;以及设置于气体再液化管线并冷却通过压缩单元压缩的蒸发气体的冷凝器,其中,压缩单元包括:第一压缩机,接收蒸发气体并压缩所接收的蒸发气体;以及第二压缩机,进一步压缩由第一压缩机压缩的蒸发气体并将进一步压缩的蒸发气体供应给冷凝器,并且第一压缩机和第二压缩机均设置为离心压缩机。
