Vasquez, G., Fonseca, N. e Guedes Soares, C. (2016), “Experimental and numerical vertical bending moments of a bulk carrier and a roll-on/roll-off ship in extreme waves”, Ocean Engineering, Vol. 124, pp. 404-418
This paper investigates the experimental and numerical vertical bending moments induced by abnormal waves on two ships, namely, a Bulk Carrier and Roll-on/Roll-off (Ro-Ro). The experimental data was obtained by seakeeping tests with scaled models in head waves at two Froude numbers. The wave traces were predefined and corresponding to wave records measured during storms in the North Sea. These wave records are particularly interesting because each of them include one abnormal wave. The ship models, which are similar in length but different in their geometry, were tested in the same predefined wave conditions. The objective is investigate the hull geometry influence on vertical bending moment under extreme sea conditions. Some conclusions are taken by comparing directly the measured responses from the two models. The experimental data is also used as benchmark to validate the predictions by a partially nonlinear time domain seakeeping numerical model. The numerical model is then used to generalize the comparative analysis between the two ships.
