Impact of Connection Properties on Dynamic Response of Modular Floating Structures

A geometric model is established based on pre-existing model tests, and the rigid module flexible connector (RMFC) concept is adopted to perform hydrodynamic analysis of the modular floating structure. To obtain knowledge of the impact of tri-axial stiffness combinations, a large number of cases are designed and the dynamic performances are plotted. In order to reduce the extreme response induced by the structural resonance, damping components are designed and integrated with elastic connectors. Cases of tri-axial combinations with different damping ratios are also put into dynamic analysis. Finally, qualitative knowledge of the impact of connection properties on the dynamic response of modular floating structures is obtained and advices on the design and optimization of connecting structures are proposed.
