摘要
针对墨西哥湾海域和西非海域,1 828.8 m水深转塔式FPSO系泊系统,利用水动力通用软件AQWA,建立风浪流作用下船体/锚链耦合系统模型,得到FPSO系泊系统频域与时域的动态响应。着重分析了浪向角180°和225°情况下的各自由度一、二阶响应。利用AQWA的缆索动力学模块,设计校核了系泊缆索受力情况。AQWA提供的时域、频域、缆索动力学多模块耦合分析,能迅速准确模拟大型复杂FPSO系泊系统响应,有很高的工程实用价值。
In this paper, by using the hydrodynamics software AQWA, a hull/mooring coupled dynamic analysis program in frequency and time domain is developed for the global motion simulation of a turret-moored,tanker based FPSO designed for 1828.8m water depth, corresponding to the 100-year storm conditions in Golf of Mexico and the sea condition of West Africa. This paper especially concerns the firstorder and second-order responses to the waves at 2 different wave incident directions 180°and 225°. The cable dynamics,a subprogram of AQWA, provides numerical results of forces and motions of each mooring line. The compound software AQWA enables fast and accurate analyze of large, complex FPSO mooring system, provides high practical value.
