HEAD AND FOLLOWING WAVE EXCITING FORCE EXPERIMENTS ON TWO SWATH CONFIGURATIONS

The heave force, surge force and pitch moment on a captive model due to regular waves have been obtained for two SWATH configurations. Exciting forces in head seas have been obtained for the SWATH 6D model and the SSP KAIMALINO model, and following-sea excitations have been obtained for the SWATH 6D model. The forces, moments and phase angles are presented for a range of regular wave frequencies. The experiments were conducted with and without propulsion which was found to have no effect on the coefficients. (Author)
