Watanabe, I. and Guedes Soares, C. (1999), “Comparative Study on the Time-Domain Analysis of Non-Linear Ship Motions and Loads”, Marine Structures, Vol. 12, N.º 3, pp. 153-170

A benchmark study has been performed by comparing the predictions of different non-linear time-domain codes applied to study the vertical wave-induced bending moment in a containership in waves of different steepness. Most methods are based on strip theory formulations applied both to rigid body and to flexible hull formulations, but one adopts a 3-D formulation. It has been shown that the results are consistent with the linear estimates in the lower wave height region. However, the agreement among the computed values becomes poor in the higher wave region when the elastic behaviour of the hull has a significant role.
