本文以我国南海某条FPSO的内转塔式单点系泊系统为例，研究内转塔式单点系泊的不同参数对于FPSO的运动和系泊张力的影响，确定单点系泊系统不同参数的敏感性。本文从系泊系统材料、系泊系统重量以及系泊缆预张力3个方面考虑其对系泊系统受力及FPSO的运动等设计参数进行敏感性分析。通过分析确定了FPSO的运动和单点系泊系统的动力响应对于系泊系统不同参数的敏感程度。
Based on a turret-moored FPSO and STP mooring system working in the South China Sea, the influence on turret's motion and mooring lines' tension affected by different coefficients of STP are analyzed. Considering mixed mooring line and clumps, a FPSO-mooring system coupled model is built up. From three aspects which are the materials, weight and the pre-tension of the mooring system, the sensitivity of the design parameters of the mooring system is checked. According to the analysis, the sensitivity of mooring system's coefficients, influencing on the dynamic response of FPSO and mooring system, is checked.
