A Coupled Hydrodynamic–Structural Model for Flexible Interconnected Multiple Floating Bodies

Evaluating the structural safety and seakeeping performance of very large floating structures (VLFS) using rigid module flexible connector (RMFC) method remains challenging due to complexity coupled hydrodynamic–structural responses in this system. In study, a frequency–time domain model is developed based on RMFC employing planar Euler–Bernoulli beam elements investigate dynamic multi-module systems. To reveal characteristics systems, are investigated frequency–time-domain numerical with viscous correction, which mass stiffness attributes connectors incorporated into Given effects hydrodynamic interaction, consideration given case three modular boxes connected by beams aligned series shallow water validate present model. Higher efficiency accuracy can be found system correction potential flow theory introducing state–space replace convolution terms Cummins equation for time domain. Moreover, extended considerable number modules, provides possibilities analyze N-module
