Abstract: The phenomenon of sudden changes in hydrodynamic coefficients cannot be neglected when the resonance of a two-dimensional rectangular moonpool occurs; however, it may not be meaningful to discuss the detailed values of hydrodynamic coefficients when the resonance occurs. The analytical solution of the hydrodynamic coefficients of a two-dimensional rectangular moonpool under sway motion derived based on the linear potential flow theory is first improved. The improved analytical results and the results with the far-field method are then compared and verified. The results show that the hydrodynamic coefficients of a two-dimensional rectangular moonpool under sway motion change suddenly at the second resonant frequency, which was not found in the original analytical solution of damping coefficient.
