Abstract:A dynamic analysis model of deep water mooring lines with buoys system is established in time domain. The contact interaction between mooring line and seabed is considered, the fluid drag force and inertia force on the mooring line are calculated according to the Morison formula. The dissipated energy by a mooring line from the floating platform as a result of its oscillation is applied to calculate the mooring-induced damping. Analysis on the impact that buoys system has on the mooring line tension and damping on which they are attached. Moreover, the parameter sensitivity analysis of buoys size and location are executed. The results above may be helpful for reducing the tension in the design of mooring system for deep water floating platform.
