Uzunoglu, E., Ribeiro e Silva, S. e Guedes Soares, C. (2015), “Numerical and experimental study of parametric rolling of a container ship in regular and irregular head waves”, Maritime Technology and Engineering, Guedes Soares, C. & Santos T.A. (Eds.), Taylor & Francis Group, London, UK, pp. 1047-1058

This paper deals with the validation of a theoretical model that is employed to foresee the susceptibility of a vessel to the occurrence of parametric rolling. The results of a series of experiments carried out on a C11 type container vessel are compared with the six degrees of freedom numerical code. Severity of the motion is discussed utilizing time series. Regular and irregular head waves are presented and the presence and the effect of coupling are examined. In addition to head waves, irregular waves are numerically and experimentally evaluated also in slightly oblique waves. Numerical results are presented in polar plots for regular and irregular waves for all headings and speeds of the vessel.
