Abstract:Applying buoys to the catenary mooring system in deep water may reduce part of the weight and radius of mooring. In order to investigate the effect that buoys system has on the dynamics of mooring systems and the motion responses of platform, the global responses of a semi-submersible platform are numerically simulated in the time domain. Firstly, the governing equations of mooring line and the hydrodynamic model of semi-submersible platform are built. Secondly, different size and location of buoys are designed to attach on the mooring line. Finally, the three hours simulations under 100-year return period of South China Sea are executed. The results may give another approach in the design of catenary mooring system.
