Model Experiment on Parametric Rolling of a Post-Panamax Containership in Head Waves

A study on the effect of parametric roll on added resistance in regular head seas

“…So far, the effect of dynamic heave and pitch motions on parametric roll has been investigated by many researchers and its mechanism is well established. The existing research revealed that restoring arm variation depending on dynamic heave and pitch motions is essential for accurately predicting parametric roll in head waves (Taguchi et al, 2006). However, these theoretical works do not deal with the effect of added resistance on parametric roll.…”

Influence of ship dynamics modelling on the prediction of fishing vessels roll response in beam and longitudinal waves

“…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).…”
