为了规避钻井船月池内发生共振情况带来的危险，本文采用势流理论和CFD数值模型相结合的方式，对钻井船的水动力性能和月池内流体运动进行研究。在入射波为月池共振周期的情况下，将船体有无耦合运动时月池内流体的不同运动进行比较研究，得出船体运动会增大月池内流体运动的结论。
To avoid the safety problems caused by some resonant conditions occurring inside the moonpool, this model intend to do some research on hydrodynamic performance of the drilling vessel and fluid motion inside the moonpool using both potential theory and CFD numerical model. When the moonpool is under the resonant conditions, according to the comparisons whether the vessel has coupled motion or not, we can reach the conclusion that the vessel motions can increase the fluid motion.
