"Optimization of liquid gas transport for LNG vessels by fluid structure interaction studies" project submitted to the Spanish R+D National Plan 2013, call, has been funded under these spanish Ministry programs .
Transport and storage of Liquefied Natural Gas (LNG) is a crucial challenge from a technological and scientific point of view due to several reasons, such as security, economic profitability and energetic dependence. In this case, transport and storage is performed at extremely low temperatures, which prevents the partitioning of the containers.. In this context the accurate calculation of the dynamic loads caused by the impact of violent fluid in the containers (sloshing) is something highly relevant. This sloshing phenomenon could cause structural problems and amplify the movements of the vessel, affecting its own security. Currently, the uncertainty in the calculation of these dynamic loads causes very strict limitations in the fillings of the containers, therefore affecting its corresponding economical costs.
