摘要
作为海上油气开发的主要设施,浮式生产储油卸油平台(FPSO)受到了研究人员和工程技术人员的高度重视。依靠自开发的时域分析代码研究系泊缆水动力系数和波浪参数对FPSO运动的影响。为验证该代码的准确性,采用水动力分析通用软件—AQWA进行FPSO运动对比研究。在不规则波浪条件下,发现由代码和AQWA得到的结果吻合良好。并对FPSO运动做了系泊缆水动力系数和波浪参数的敏感性分析。结果表明,系泊缆水动力系数和波浪参数对FPSO的运动有较大影响。同时,由于转塔式系泊的配置,波频运动不受系泊线水动力系数的影响。该研究所得结论对于FPSO系统的初始设计具有一定的参考价值。
As the main facilities for offshore oil and gas development,floating production storage and offloading platforms(FPSOs)have received much attention from researchers and engineering technologists.This paper studies the influence of mooring line hydrodynamic coefficients and wave parameters on FPSO motions using an in-house time domain analysis code.To verify the accuracy of the code,a comparative study of FPSO motions was carried out using the commercial hydrodynamic analysis software AQWA.Under irregular wave conditions,the results obtained from the code and AQWA were found to match very well.Therefore,the code can be considered reliable.Subsequently,sensitivity analyses of mooring line hydrodynamic coefficients and wave parameters on FPSO motions were performed.The results show that mooring line hydrodynamic coefficients and wave parameters have a significant influence on FPSO motions.However,it should be noted that the heave motion is not affected by the mooring line hydrodynamic coefficients due to the turret mooring configuration.In summary,the conclusions obtained in this paper have certain reference value for the initial design of FPSO systems.
