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 delayof a propagation of a damage on a mooring line to the other lines, on theother hand, it has been said that it is difficult to detect the damage in thesystem. In this paper, we introduce a hydrodynamic response of a floatingbody and mooring lines by numerical simulation results in case that amooring line contacting the seabed has been broken. Then we discuss thedifference of the hydrodynamic response before the breakage and afterthe breakage.
