Coupled Motion Response of a Moored Floating Body in Breaking a Mooring Line in Waves

摘要

A catenary mooring system has a feature point that is able to make a delay of a propagation of a damage on a mooring line to the other lines, on the other hand, it has been said that it is difficult to detect the damage in the system. In this paper, we introduce a hydrodynamic response of a floating body and mooring lines by numerical simulation results in case that a mooring line contacting the seabed has been broken. Then we discuss the difference of the hydrodynamic response before the breakage and after the breakage.
