| Outline of Final Research Achievements |
As a cleaner alternative to other fossil fuels, the demand for liquefied natural gas (LNG) is steadily increasing. This has resulted in technical innovations in the LNG supply chain. Among the various LNG tank systems, the membrane LNG tank and the spherical LNG tank are mainly used as practical storage systems. Increases in the size of the tank and the emergence of new operation modes of LNG carriers such as their usage as shuttle tankers for FLNG can lead to a partially filled condition which was not common in the past. In this context, the prediction of the dynamic behaviors of liquid cargo has become essential topics. Fundamental information was obtained regarding the sloshing motion, such as the criteria for the generation of sloshing and swirling, the coupling effect between the ship motion and the liquid motion, etc. In this study, we proposed a simple anti-sloshing floating device to be installed inside liquid cargo tanks and examined the performance of the proposed device.
