Eigen frequencies for vertical vibration of very large and comparatively flexible floating structure exist continuously in relatively high frequency zone due to the buoyancy effect. On the other hand, the lowest eigen frequency for horizontal vibration may appear in the lower frequency zone than the heave-mode frequency, because of no effect of buoyancy on the horizontal deflection behavior. Therefore it is important to investigate the dynamic response in the lower frequency zone than the heave-mode frequency. This paper deals with the dynamic behavior for the horizontal deflection of a very large floating structure using the combined model considering the shear rigidity of the main structure and mooring effects. Effects of mooring characteristics and structure parameters on the dynamic response are discussed.
