| 摘 要： | 为研究月池开孔对FPSO水动力性能和波浪载荷的影响,基于三维势流理论和波浪诱导载荷理论,分析了不同的月池尺寸、不同的月池纵向位置以及不同的船体吃水时附加质量和附加阻尼的变化趋势。并进行了含月池开孔的FPSO波浪诱导载荷的长期预报,得到了截面垂向剪力和弯矩沿船长方向的分布规律,分析了月池尺寸对波浪诱导载荷的影响。结果表明含有月池的FPSO船体的垂向附加质量和附加阻尼会出现一个峰值,随月池尺寸增加而逐渐减小；月池处垂向剪力和垂向弯矩随月池尺寸增大有小幅度减小。

| Abstract: | In order to study the influence of the moon pool on the hydrodynamic performance and wave load of Deepwater FPSO, based on 3D potential theory and wave induced load theory, analysis additional mass and additional damping in different size of month pool, different position of month pool, different draft of FPSO hull. The long-term prediction of wave induced loading of FPSO with moon pool is also analyzed. The distribution of vertical shear force and moment is obtained. The influence of size of moon pool to wave induced load is analyzed. It is indicated that there is a peak value of the additional mass and additional damping of the FPSO with moon pool. And the value decreases with the increase of the size of moon pool. The vertical shear force and vertical bending moment decreases with the size of the moon pool. |
