LNG demand has been rapidly increasing in Korea for a variety of reaso including stable supply, non- polluting, and high combustion efficiency characteris As a result the construction and expansion of LNG storage facilities have b continuing at a vigorous pace. One of the most important structural core elemen the LNG storage tank is the membrane, consisting of stainless steel. The memb to be applied inside of LNG storage tank is provided with corrugations to abs thermal contraction and expansion caused by LNG temperature. From the viewp of strength design, however. it is essential to confirm that the membrane undergo a stable deformation and has a sufficient fatigue strength Experim studies are presented to investigate the deformation and strength of the memb which is designed by Kogas. All experiments are conducted on the basis of RP and we found the results is fully satisfied with the RPIS.

Natural gas became one of the major sources of energy in Korea. As the consumption of natural gas increase, the more capacity of the LNG storage tanks Is required. Recently, Korea Gas Corp.(KOGAS) has developed the technology nt' designing the LNG storage tanks. In this study, some of the finite element analysis has been made for designing of the roof structure of LNG storage tanks. The load case and safety code used In this study were followed by BS7777.
