Homoclinic Phenomena in Ship Motions
Journal of Ship Research, 2017In the article will be reviewed the changes of ship motion patterns originating from a special class of phase space phenomena identified in the nonlinear dynamics literature as homoclinic (When the term appears in italic, it will imply truly homoclinic as well as heteroclinic events).

PARAMETRIC ESTIMATION OF THE DIRECTIONAL WAVE SPECTRUM FROM SHIP MOTIONS
International Journal of Maritime Engineering, 2021A parametric estimation of the directional wave spectrum based on ship motions is presented. The estimation of the sea- state parameters is essential to have an updated data base of the main characteristics of the sea-state, which are useful for several ...

EFD and CFD Study of Forces, Ship Motions, and Flow Field for KRISO Container Ship Model in Waves
Journal of Ship Research, 2020Ship motion responses and added resistance in waves have been predicted by a wide variety of computational tools. However, validation of the computational flow field still remains a challenge.

Journal of Ship Research, 1998
A nonlinear numerical method has been developed to compute motion responses for a ship traveling in steep ambient waves. The method is based on an approximate theory and is an extension to a well-established linear time-domain numerical method. The nonlinear solution is found to be greatly improved over the classical linear and quasi-nonlinear ...

Abstract In this paper we describe an indirect approach to short-term prediction of the rolling motion of ships. A key assumption used in the development is that for short time periods, the spectral content of the motion is concentrated in narrow-bands.

AbstractThe ship capsizing problem is one of the major challenges in naval architecture. The IMO criterion regarding capsize stability is still the righting lever curve of static stability calculated for calm water. For the prediction of large–amplitude motions the dynamic loads have to be included. The capsizing of a ship in regular waves is resulting

International Journal of Adaptive Control and Signal Processing
Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using

Numerical Simulation of Ship Motions in Regular and Irregular Waves
Marine Technology Society journal, 2019A numerical simulation method is presented in this study to predict ship resistance and motion responses in regular and irregular waves. The unsteady RANS (Reynolds Average Navier-Stokes) method is selected as the governing equation, and a volume of ...
