Abstract:
 A series of berthing tests are conducted on a 1∶40,scale model of the new floating mooring system in the
non-wave-induced condition to analyze the influence of vessel’s displacement and berthing velocity and other factors
on the dynamic response of the new floating mooring system,and the test results of the new floating mooring are
compared with the results of rigid berthing system in the same conditions,and further berthing analysis of the floating
mooring system is done by the model tests in the wave with wave height of 2,m,wave period of 6,s and 90°incident
angle to obtain the dynamic response of the floating mooring system with the different berthing velocities. The results
show that the impact force is smaller and the absorption of energy is larger in floating berthing compared with those in
rigid berthing. Berthing velocity and displacement of the vessel are the main factors of the berthing dynamic
response,and the impact force on fenders and displacement of berthing and mooring platform will increase greatly
with the increase of berthing velocity and displacement of the vessel. Owing to the uneven distribution of vessel
mass,berthing takes place first at bow berthing and mooring platform,most of the energy is absorbed by the bow
berthing and mooring platform while the stern berthing and mooring platform absorbs only a very small proportion of
the berthing energy. Especially when the initial berthing energy is small,the differences of the two platforms in the
energy absorption are more obvious. As the berthing velocity and displacement of the vessel increase,the time interval
between the bow and stern berthing becomes smaller,the differences of platform displacement and impact force
on fender between two berthing and mooring platforms become smaller,and energy-absorbing ratio of stern berthing
and mooring platform gradually increase.
