超强台风下“南海奋进”号FPSO系泊能力分析

摘要

Based on the theory of hydrodynamic analysis and the theory of three-dimensional diffraction-radiation,the hydrodynamic calculation of the underwater part of the "NANHAI FENJIN" FPSO floating body is carried out by the frequency domain analysis method.Based on the hydrodynamic analysis results,the semi-infinite coupling analysis method is applied to analyze the mooring system of FPSO under the super typhoon.The results show that for the"FENJIN" FPSO in the draft within the scope of 14.0 m～14.5 m the mooring system bears the smallest force,mooring force decreases by 9％ to 12 ％,the anti-typhoon capacity is the strongest in this loading state,and the critical condition is improved to level 16.%基于水动力分析理论和三维绕射-辐射理论,采用频域分析方法,对“南海奋进”号FPSO浮体水下部分进行水动力计算.基于水动力分析结果,利用时域半耦合分析法对FPSO进行超强台风下的系泊系统分析,结果表明:“南海奋进”号FPSO在吃水为14.0～14.5 m内系泊系统的受力最小,系泊力下降约9％至12％,抗台风能力在该装载状态下最强,临界工况提高到16级.
