【Abstract】 Soft yoke mooring system has been widely used in ocean oil production activities in Bohai Bay of China to permanently moor a floating production,storage and offloading(FPSO) in shallow water and withstand various environments.A theoretical model of the soft yoke mooring system was founded to simulate its properties and mechanism.A numerical iteration algorithm based on error estimation was developed to calculate the dynamic response of the mooring system due to 6D motions of FPSO.Model test is carried out to verify the numerical simulation.It is shown that the numerical simulation takes only a few iteration times and the errors are small.Furthermore,the agreement of comparisons between the numerical and experimental results is quite good.Based on the efficient model and numerical algorithm,developing a real-time monitoring system is proposed to observe the dynamic performance of soft yoke moored FPSO under real various sea environments.更多还原
