A liquefied gas shipping system is disclosed. The liquefied gas shipping system according to an embodiment of the present invention comprises: a first compression part that receives and compresses boil-off gas generated inside a second storage tank during a shipping process of supplying liquefied gas from a first storage tank on a supply side to the second storage tank on a receiving side; a second compression part that receives and compresses at least a part of the boil-off gas generated inside the second storage tank; and an ejector that receives the boil-off gas compressed by the second compression part as a driving fluid and sucks in at least a part of the boil-off gas generated inside the second storage tank, wherein a mixture of the boil-off gas compressed by the first compression part and the fluid discharged by the ejector is returned to the supply side. Thus, an embodiment of the present invention is to provide the liquefied gas shipping system that can efficiently process boil-off gas generated in a storage tank on the side that receives liquefied gas when shipping liquefied gas.
