Multiscale attention-based LSTM for ship motion prediction

, 2021
Ship motion prediction is applied to the shipboard stabilized platform to keep the equipment on the platform stable all the time, which is of great practical significance to the safety and efficiency of shipboard equipment operation.

Nonlinear Ship Motions

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 ...

Research on Ship Motion Prediction Algorithm Based on Dual-Pass Long Short-Term Memory Neural Network

IEEE Access, 2021
When forecasting ship movements, the random errors of the inertial navigation system (INS) seriously affect the accuracy of general prediction methods. In actual measurement, the main causes of the random errors are electrostatic bias and micro-electric ...

Ship Motion Prediction

IFAC Proceedings Volumes, 1993
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.

Dynamics of Ship–Motion

PAMM, 2003
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

An online identification approach for a nonlinear ship motion model based on a receding horizon

Transactions of the Institute of Measurement and Control, 2021
The ship motion system is a nonlinear control object, and its system parameters exhibit time-varying characteristics with the ship motion state, which increases the difficulty of control.
