Cyclic nonlinear analysis of new-type deepwater mooring systems

The deepwater taut-wire mooring systems use the synthetic fiber ropes as the main part of the mooring lines.It is the complicated mechanical properties of the mooring lines and the characteristics of the mooring systems that bring new problems needed to be acquainted with profoundly in the design,analysis and!engineering application of the taut-wire mooring systems.The dynamic analysis of a mooring floater is conducted to examine the dynamic stiffness of the fiber ropes under cyclic load,and the dynamic response of both the catenary mooring system and the taut-wire mooring system is compared.The analysis indicates that the mooring performance of the taut-wire mooring system is better but the tension response is more complicated.These cognitions will provide significant reference for the research development and engineering application of the taut-wire mooring system.
