Mathematical models are essential for the design and control of offshore systems, to simulate the fluid?structure interactions and predict the motions and the structural loads. In the development and derivation of the models, simplifying assumptions are ...

Parametric resonance is a dynamic instability due to the internal transfer of energy between degrees of freedom. Parametric resonance is known to cause large unstable pitch and/or roll motions in floating bodies, and has been observed in wave energy conv...

This review focuses on the most suitable form of hydrodynamic modeling for the next generation wave energy converter (WEC) design tools. To design and optimize a WEC, it is estimated that several million hours of operation must be simulated, perhaps one ...
