A liquefied natural gas (LNG) loading system and a liquefied natural gas loading method for sea trials of a propulsion ship are disclosed. According to one aspect of the present invention, the LNG loading system for sea trials of a propulsion ship comprises: a storage tank provided in a hull; a spray crossover line that selectively delivers liquid nitrogen for cooling or LNG from an onshore terminal or bunkering ship; a spray main line that selectively receives the LNG or liquefied nitrogen for cooling from the spray crossover line and supplies the same to the storage tank; a liquid main line that receives LNG from a liquid crossover line and supplies the same to the storage tank; and a vapor main line connected to the storage tank to discharge boil-off gas generated inside the storage tank to the outside.
