Physical Model Tests on Dynamic Behavior of a Moored Large Bulk Carrier affected by Pretension and Fender Type under Wave

In our previous study, investigations on property of ship motions due to characteristic of mooring system such as mooring line and fender was conducted through a numerical simulation and a field observation of ship motions and mooring loads. From the investigations, it was concluded that large sway motion, namely sub-harmonic motion which was caused by an asymmetrical mooring of mooring line and fender, and large roll motion were induced in beam seas. In this study, we have conducted a physical model test on ship motions and mooring loads for a large vessel moored along dolphin to confirm the effect of pretension of mooring line and fender property.
