Mathematical models for capsizing due to broaching, one of the great threat to ships running in following and quartering seas, have been developed by many researchers. However these models can predict it only qualitatively. For realising quantitative prediction of broaching, we have conducted systematic captive model experiments with large heel angles up to 50 degrees in severe following waves. As a result, the details of nonlinear heel-induced hydrodynamic forces with respect to heel angle in waves are presented. Then comparisons between a free running model experiment and the numerical simulation with direct use of the measured heel-induced hydrodynamic forces are carried out. As a result, the mathematical model for realising quantitative prediction of broaching in severe following and quartering seas is presented. Finally the simplified mathematical model is also proposed for more practical uses with less experimental efforts. © Springer Science+Business Media B.V. 2011.
