Various studies are being conducted recently on land piping for supplying and carrying cryogenic (‐163 °C) LNG to ships. In transportation through land piping, however, the problem of BOG (Boil Off Gas) happens frequently due to difficulty in insulating the outside of the pipe. One of the methods for minimizing the occurrence of BOG is using double pipe in piping. However, research has not been made enough for the method of minimizing heat loss through inserting insulator with high insulation performance inside the double pipe and vacuuming. Thus, in planning vacuum insulated piping, this study selected the optimal combination of design factors for vacuum insulated piping using experimental design among optimal design techniques. In addition, numerical analysis was conducted together in order to test the combination of design factors, and the results are expected to provide basic information for vacuum insulated piping design.
