摘要：

The hydrodynamic behavior of a submerged horizontal cylinder moored in waves was studied through numerical methods as a participant of the COER Hydrodynamic Modeling Competition. The potential theory with additional viscous damping has been used to model the problem. Three different simulation cases have been constructed to identify (i) the general behaviors of the cylinder subjected to the input wave, (ii) the effect of the second-order hydrodynamic forces, and (iii) the effect of exact wetted surface issue. Computational results were compared to the experiment, and a reasonable degree of accuracy has been confirmed.
