Experimental Study of Ship Motion Effect on Pressurization and Holding Time of Tank Containers during Marine Transportation

Liquefied natural gas (LNG) is the cleanest fossil fuel available, producing less carbon emissions and fewer pollutants than other fuels. Marine transportation a key process in LNG supply chain. The use of tank containers, which are portable equipment, can effectively facilitate multi-mode transportation. evaporation causes pressurization, safety concern during Ship motion environmental temperature main factors affecting pressure variations. In this study, effect ship on pressurization holding time was investigated through three types experiments, namely, prototype, field, self-pressurization experiments. results showed that while increased boil-off generated due to motion, remained stable dynamic cases. Higher rates were obtained under more severe conditions, shortened. two different effects development discussed here facilitation enhancement heat transfer prevention condensation at vapor–liquid interface. These show varied levels predominance over variations depending stages experiments able reach 87 days most condition, long enough for long-term shipping; transporting containers further based experimental herein.
