This study is on the comparison of moss and membrane type LNG carrier in cooldown procedure. The cooldown is a preprocess of the LNG loading procedure and is important to analyze Tank's wall temperature, heat transfer coefficient and flowrate of BOG(Boil off gas) This calculated value is used in the process design such as capacity of compressor and line size, and the structural design of tank. To compare two different type carriers, boundary condition that satify the requirement by KOGAS is used. This calculation use unsteady state model concerned heat ingress from hold space to tank's wall.
