“…In the case of parametric roll resonance, it is also well worth mentioning also 3-DOF models, which include the dynamic coupling effects of pitch and heave on roll motion, which are of paramount importance for the correct evaluation of the phenomenon (Munif and Umeda, 2006;Taguchi et al, 2011). An example of this alternative was presented by Neves and Rodríguez (2006), which has been applied to the evaluation of the behaviour of parametric roll in regular longitudinal waves for the case of fishing vessels (Neves and Rodríguez, 2009) and other cargo ships (Rodríguez et al, 2007).…”
