Advanced studies on the hydroelasticity of ships and offshore structures within project GCRC-SOP Korea

Hydroelasticity is actual branch of science dealing with ships and offshore structure dynamics, simultaneously considering their motions and elastic deformations. During the last decade the above mentioned problem has been also investigated at the Faculty of Mechanical Engineering and Naval Architecture (FAMENA), University of Zagreb. This paper brings an overview of the main research goals and results of hydroelasticity investigation within the projects funded by South Korean Government through the Global Core Research Center for Ships and Offshore Plants (GCRC-SOP). Among others, project participants are the Pusan National University, Busan, Korea, Bureau Veritas (BV), Paris, France as well as FAMENA Zagreb. All projects, funded through GCRC-SOP are presented, with emphasis to those related to investigation of hydroelasticity. Detailed description of the considered problems is given: development of sophisticated beam structural model and its application in the hydroelastic analysis of large container ships ; formulation of restoring stiffness and its role in the response of tension leg platforms (TLP) ; analytical solution for second order hydroelastic vibrations of vertical circular cylinder.
