Minimizing the resonant behavior of the entrapped water within a moonpool is beneficial for marine operations. However, analyzing various methods for minimizing this behavior is difficult, as properly capturing the resonant behavior numerically has proven to be difficult. Traditional analyses utilizing potential flow theory have grossly overestimated the amount of amplification. This paper utilizes the advanced analysis technique of SPH (Smoothed Particle Hydrodynamics), to perform a comparison of the beneficial effects on the resonant behavior of the entrapped water by altering the moonpool geometry. Analyses are performed on a simplified drillship using forced heave oscillations.
