PURPOSE: A method for calculating input thermal energy into a cargo space, capable of inducing an evaporation rate of a cargo space, is provided to perform accurate calculating the thermal energy input from a cargo space supporting part. CONSTITUTION: A method for calculating input thermal energy into a cargo space is as follows. It is supported on hull with a cargo space supporting part. The thermal energy flowing into the cargo space for storing LNG having an insulation part at the external side of the supporting part is calculated. The average heat capacity coefficient of the heat input amount is calculated through a supporting part and the insulation part according to CFD analysis per a plurality of materials comprising the cargo space supporting part and the insulation part. The heat input amount to the cargo space is calculated by using a calculated coefficient(S101). The characteristic length is controlled according to the shape of independent angular domains by dividing the cargo space into a plurality of sections after modeling(S102). The average heat capacity coefficient of the heat input amount through the supporting part and insulation part are in something drawn with the CFD interpretation. The temperature value of hull and section is initialized(S103). The overall heat transmission coefficient including the average heat capacity coefficient at the angular domain is in something drawn.
