Disclosed are a liquefied gas carrier and an operating method thereof. According to one embodiment of the present invention, the liquefied gas carrier includes: a storage tank receiving liquefied natural gas therein when sailing to a demand source of natural gas from a producer of the natural gas and receiving liquid nitrogen when sailing to the producer from the demand source; a buffer tank supplied with the liquid nitrogen from the demand source to receive the same; a boil off gas re-liquefying line supplied with boil off gas generated therein to re-liquefy the same when receiving the liquefied natural gas in the storage tank; a nitrogen supply line supplied with the liquid nitrogen from the buffer tank to convert the same to nitrogen gas and supplying the same to a nitrogen demand facility in a hull; and a heat exchanger heat-exchanging the boil off gas transferred along the boil off re-liquefying line and the liquid nitrogen transferred along the nitrogen supply line.

    액화가스 수송선 및 이의 운용방법이 개시된다. 본 실시 예에 의한 액화가스 수송선은 천연가스의 산지로부터 천연가스의 수요처로 운항 시 내부에 액화천연가스를 수용하고, 수요처로부터 산지로 운항 시 내부에 액체질소를 수용하는 저장탱크, 수요처에서 액체질소를 공급받아 수용하는 버퍼탱크, 저장탱크에 액화천연가스 수용 시, 내부에 발생하는 증발가스를 공급받아 재액화시키는 증발가스 재액화라인, 버퍼탱크로부터 액체질소를 공급받아 질소가스로 변환하여 선체 내 질소 수요설비로 공급하는 질소 공급라인 및 증발가스 재액화라인을 따라 이송되는 증발가스와 질소 공급라인을 따라 이송되는 액체질소를 열교환하는 열교환장치를 포함하여 제공될 수 있다.
