Abstract (en)

Disclosed herein is a method and apparatus for stable supply of natural gas (312) to a gas demand side (350) in an LNG carrier. With the method, natural gas comprising natural boil-off gas (313) generated in a cargo tank (310) containing LNG and forced boil-off gas generated by vaporizing LNG pumped from the cargo tank (310) is supplied to the gas demand side. The forced boil-off gas or a mixed gas of the forced boil-off gas and natural boil-off gas having a predetermined pressure or more is returned to the cargo tank or to a gas header connecting a plurality of the cargo tanks to one another to supply the natural gas at the predetermined pressure or more.
