The Development of Corner Membrane for LNG Storage Tank

LNG저장탱크용 코너 멤브레인 개발

Both analytical and experimental studies are presented to investigate the strength of the membrane which is designed by Kogas and will be used as a sealing for a LNG tank. Kogas has already developed the Ring-Knot type membrane, but new type had yet to be developed. This paper reports on the results of investigations into this new type of membrane. Various theorical analyses using FEM and experiments are conducted on the basis of RPIS, and it is found that the RPIS is fully satisfied.
