Outline of Final Research Achievements

In order to establish a Rankine panel method in the frequency domain as the core calculation method in the prediction system for seakeeping performance (including the fluid-structure coupled responses) of ships in actual seas, an intensive study was made for making the method applicable to a wide range of oscillation frequencies and forward speeds of a ship. Experiments have been also conducted to see the importance of nonlinearity in hydrodynamic forces acting on a ship and it was found that the nonlinearity in the cross-coupling hydrodynamic forces between heave and pitch plays an important role in the nonlinearity in ship-motion amplitudes around the resonant frequency. Furthermore, simultaneous measurements have been successfully made for obtaining the spatial unsteady-pressure distribution on the ship hull by use of 224 FBG-type pressure sensors, together with the measurement of wave-induced ship motions, added resistance, and unsteady wave pattern on the free surface.
