The present invention relates to an insulation system for a liquefied gas storage tank and a ship having the same. The insulation system for a liquefied gas storage tank of the present invention includes: a cofferdam heating part for heating a cofferdam by using a heat medium; a cooling part provided on a wall of the liquefied gas storage tank to cool the liquefied gas storage tank by using a refrigerant; and a heat exchange part for exchanging heat between the refrigerant of the cooling part and the heat medium cooled while the cofferdam is heated. Therefore, a boil-off rate (BOR) can be reduced without the application of an insulation material having excellent insulating performance.
