Abstract

Global hydroelastic response of the ships carrying liquid cargo (LNG ships, tankers, dry cargo ships in ballast conditions...) can be influenced by the dynamics of liquid motions.The presence of the liquid cargo does not only change the structural natural frequencies but also introduce the additional resonant conditions due to the natural sloshing modes. In order to properly take into account the hydroelastic interaction in between two resonant systems (the floating body and the tanks) a fully coupled model should be used. The development of the fully consistent coupled hydroelastic model for general ship structure such as LNG carrier is quite complex and it is very usefull to have the reference data for validation. The purpose of this paper is to provide those data for the case of the simplified configuration which consists of the vertical circular cylinder with the liquid filled tank on its top. For this case it is possible to provide a highly accurated semi-analytical solution.
