Prediction of Parametric Roll of Ships in Regular and Irregular Sea
… research was done to develop tools to predict parametric roll motion of ships in regular and irregular sea and provide guidelines to avoid parametric roll during initial design stage. A post Panamax hull form (modified C11 Hull form, Courtesy of MARIN) was used to study parametric roll in …

Análise da estabilidade intacta de navios de apoio offshore sob perspectiva da segunda geração de critérios de estabilidade da IMO
… of ships in five modes of stability failure: parametric roll, pure loss of stability, broaching, dead ship condition and excessive acceleration. The present work aims to investigate and analyze these criteria for the case of an offshore support vessel, focusing on the parametric roll and pure …

Estudo das características estocásticas do roll paramétrico
… models are capable of simulating the heave, roll and pitch motions under regular and irregular longitudinal waves. Especial effort has been made in capturing in an accurate and efficient manner the restoring actions in the developed models. This is a fundamental feature required in order to …

Identification of Finite-Degree-of-Freedom Models for Ship Motions
… and predict the ship motions. For linear parametric identification, we use the Eigensystem Realization Algorithm (ERA) to determine the coefficients in the linearly coupled equations and the effects of the forward speed on these coefficients. For linear nonparametric identification, we …
