Application of time-domain methods for marine hydrodynamic and hydroelasticity analyses of floating systems

The application of transient three-dimensional numerical code ITU-WAVE is presented for the prediction hydrodynamic characteristics floating bodies. time histories unsteady motions are directly with respect to Impulse Response Functions (IRFs). First-order steady forces wave-resistance, sinkage force and trim moment solved as steady-state limit surge radiation IRF. second-order mean using near-field method based on direct pressure integration. structural parts fully coupled through modal analysis solution hydroelastic analysis. A stiff structure then studied assuming that contributions rigid body modes much bigger than elastic modes. discrete control latching used increase bandwidth efficiency Wave Energy Converters (WEC). results different bodies show satisfactory agreements compared analytical, other experimental results.
