Numerical procedures and practical experience of assessment of parametric roll of container carriers

Abstract

The paper examines several aspects related to practical assessment of parametric roll of container carriers. The numerical procedure is based on application of the Large Amplitude Motion Program (LAMP), the nonlinear potential flow code. Viscous roll damping is included from the roll decay test. The rational choice of the loading conditions is considered. Practical non-ergodicity of the response is taken into account. © Springer Science+Business Media B.V. 2011.
