영문 초록

This study is about the thermal design program that calculates temperature distributions of hull and insulation and analyzes the Boil-off ratio on the membrane type LNG carrier in the laden voyage. The calculation model is 1/4 of cargo tank and cofferdam on the No.3 parts of LNG carrier. The mesh number is selected 77,890 mesh for the degree of accuracy and time on the calculation. The lowest air temperature in compartments is calculated as -21.81°C under the USCG condition(Tair=-18°C, Tsw=32°C and the highest temperature in compartment is 38.02°C under the IMO IGC condition(Tair=45°C, Tsw=32°C of the maximum boil-off condition. At now BOR value is 0.1006%/day and it is the lower value than 0.15%/day required by KOGAS.
