| 摘 要： | 采用数值模拟的方法，分析了不同尺寸、位置、吃水的月池对FDPSO船体附加质量和阻尼系数的影响。建立FDPSO三维水动力模型，采用水动力计算软件AQWA，研究了月池在不同尺寸、位置、吃水情况下对FDPSO横荡、垂荡、横摇附加质量和阻尼力的影响。结果表明：月池内流体的“活塞”振荡会增大船体的垂荡运动；FDPSO船体附加质量和阻尼力在频域范围内存在极值，垂向附加质量和阻尼力极值对应的波浪频率位置与月池尺寸、吃水有关，与位置无关。

| Abstract: | The influence of fluid motion in moonpool on the FDPSO hydrodynamic performance emphasizing on added mass and damping is investigated by numerical simulation approach, 3-D hydrodynamic models of FDPSO with different size, location and draught moonpool are established. With the calculation software AQWA, the effect of moonpool with different size, location and draught on sway, heave and roll of FDPSO has been studied. The result shows that the fluid piston motion in moonpool increases the heave motion of the hull and that added mass and damping of FDPSO exhibit a peak walue in frequency domain. The peak walue position of added mass and damping in heave motion is closely related to the size and draught, but unrelated to the location of moonpool. |
