One Consideration to Characteristics on Natural Period and Damping Effect of a Moored Large Bulk Carrier

大型係留船の固有周期と減衰特性に関する一考察

In the previous study, investigations on property of ship motions was conducted through a numerical simulation and a field observation of ship motions and mooring loads. From the investigations, it was concluded that low-frequency motions such as sway, surge and yaw were induced significantly by resonant effects with the long-period wave, and resonant roll motion also occurred at the berth due to the swell component of the wave. It is important for the investigations on property of the ship motions to estimate the natural periods of each ship motion and damping effects precisely as possible. In this study, the authors have conducted a physical model test on free oscillations of the model ship for a large vessel moored along dolphin to obtain the property of the natural periods and the damping effects.
