摘　　要：Polyester mooring has become increasing popular to serve as permanent station-keeping system for deepwater floating system during recent years. Comparing to the traditional steel wire mooring,polyester mooring provides significant benefits in deepwater,such as reduced installed capital expenditure (CAPEX) and smaller vertical loads on host platform. Polyester rope is a visco-elastic material,and its stiffness is nonlinear and affected by mean load,load range,loading period and loading history. There is a perception that the polyester stiffness model has significant impact on the floating system's performance. This paper presents a detailed description and comparison of two stiffness models and three analytic approaches,and provides a systematic study of the impact of polyester mooring stiffness modeling on the deepwater floating system performance.
