<p>A boil-off gas processing device which re-liquefies a boil-off gas (22) generated within a liquefied gas tank (2) that stores a liquefied gas (21), and returns the re-liquefied gas to the liquefied gas tank (2), and which has a boil-off gas discharge line (3) that discharges the boil-off gas (22) from the liquefied gas tank (2) to the outside, and a boil-off gas reliquefaction line (4) a portion of which is immersed in the liquified gas (21) inside the liquefied gas tank (2). The boil-off gas reliquefaction line (4) has a pressure maintenance means (42) that maintains the pressure required for reliquefaction of the boil-off gas (22), and the reliquefaction line (4) has a length (L) capable of absorbing the amount of heat required for reliquefaction of the boil-off gas (22).</p> |
