LNG cryogenic flexible hose is one of the key devices in exploitation, transportation and storage of LNG (liquefied natural gas), which is called as the "blood vessel" of LNG transportation system. With the exploitation and transportation of LNG gradually from offshore to deep sea in recent years, there is a broader development prospect for LNG cryogenic flexible hose and its application technology. In order to verify the design theory and safety of engineering application of LNG cryogenic flexible hose, experimental testing technology has become an indispensable analytical means to study the mechanical properties of the hose. This paper focuses on the research of experimental test of LNG cryogenic flexible hose and investigates related technologies. Then both domestic and abroad research progress of experimental testing technology of LNG cryogenic flexible hose is summarized and the future research hotspots of experimental testing technology are prospected. Since China started related research of LNG cryogenic flexible hose relatively late it is of great significance to break through key technologies of LNG cryogenic flexible hose and to realize the domestic manufacturing process.
