【摘要】：当FPSO服役于目标油田时,将受到风浪流的作用力。其中,风力给FPSO一个恒定的静力,使其偏离原来的位置。风力计算在FPSO系泊系统的分析过程中是非常重要的。设计人员常常参考OCIMF进行风力计算,或者参考API规范得出。OCIMF为针对油轮的计算规范,但使用OCIMF计算FPSO风力及流力的方法,与FPSO的适应性仍需要进一步论证。API规范针对海上浮式系统,其计算风流力的方法使用也非常广泛,其原理为将FPSO上部各个模块风力叠加得出。以FPSO风载荷为研究对象,开展了风洞模型试验,获得了典型FPSO风载荷特性曲线,并将试验结果分别与OCIMF结果和API规范计算结果进行对比分析,最终给出FPSO风力计算方法的建议。本数据可用于FPSO的风力计算,也可为FPSO运动、系泊的设计研究提供参考。
[Abstract]:When FPSO serves in a target oil field, it is subjected to wind, wave and current forces. Where the wind gives FPSO a constant static force, Wind calculation is very important in the analysis of FPSO mooring systems. Designers often refer to the OCIMF for wind calculation or refer to the API specification for the calculation of tankers. However, the adaptability of the OCIMF method to the calculation of FPSO wind force and current force needs to be further demonstrated. The API specification is aimed at the floating offshore system, and the method of calculating the wind current force is also widely used. The principle is the wind superposition of each module in the upper part of FPSO. Taking the wind load of FPSO as the research object, the wind tunnel model test is carried out, and the characteristic curve of wind load of typical FPSO is obtained. The experimental results are compared with the results of OCIMF and API code. Finally, the method of FPSO wind power calculation is suggested. This data can be used in the calculation of FPSO wind force, and can also provide a reference for the design and study of FPSO motion and mooring.
