A MonteCarlo based methodology for the evaluation of the uncertainty connected with the parameter estimation from experimental results of large amplitude rolling motion in a regular beam sea has been developed. The application to two typical cases, a fishing vessel with quasi-linear righting moment and a frigate with highly nonlinear righting moment was considered. The results indicate that the separation capability between damping and excitation parameters is excellent, while that between different damping contributions is not completely satisfactory.

Abstract
A MonteCarlo based methodology for the evaluation of the uncertainty connected with the parameter estimation from experimental results of large amplitude rolling motion in a regular beam sea has been developed. The application to two typical cases, a fishing vessel with quasi-linear righting moment and a frigate with highly nonlinear righting moment was considered. The results indicate that the separation capability between damping and excitation parameters is excellent, while that between different damping contributions is not completely satisfactory.File in questo prodotto:
