恶劣海况下海洋石油116内转塔式FPSO装配载优化

Analysis on Loading Optimization of Inner Turret Moored HYSY 116 FPSO under Severe Sea State

为了减小恶劣海况下的FPSO系泊力,在三维势流理论基础上建立FPSO-转塔-锚链的耦合模型,在时域内对作业于南海海域的海洋石油116FPSO进行系泊分析,获得在该海况下不同装载量和不同装载方式锚链的系泊力,对比表明,FPSO在均布装载时系泊力最大,在靠近FPSO后侧装载时系泊力最小,为FPSO的最优装载工况及实际作业提供优化建议。

In order to reduce the mooting load of FPSO in severe sea state as far as possible, the coupling model, including FPSO, turret and mooting line is established. Based on 3 D potential theory, the mooring condition of HYSY 116 FPSO operating in South China Sea is analyzed to get the mooting force with different loadage and loading ways. Comparing with the mooting forces, it is found that the mooting force is the largest in case of average loadage, and the mooring force is the least when the load is near to the rear. It could provide optimizational suggestion and reference for actual operation.
