Abstract

Based on the direct time domain method of hydrodynamic calculation of floating body and the static analysis method of mooring line, the time domain motion equation of combined mooring system under external load input is established, and the mooring capacity of main mooring line is improved by adding anchor chain counterweight, and the main mooring line is used as the main position and attitude control module of the system for in-depth research. The results show that the horizontal traction on the platform edge is reduced by 36.7% on average by using the combined mooring method. Compared with the four-point mooring system, the horizontal restoring force provided by the combined mooring system is increased by 27% on average, and the mooring tension is decreased by 34% on average. The combined mooring system not only meets the mooring conditions of the floating platform, but also greatly reduces the impact on the wave fluctuation characteristics of the platform.
