An enhanced model based on deep operator network for very short-term forecasting of ship motion
The Physics of FluidsVery short-term forecasting of ship motion involves forecasting future ship movements based on learned characteristics from historical motion data. However, ship motion exhibits not only temporal features but also features in the frequency domain, which ...

Near Term Ship Motion Forecasting From Prior Motion
Volume 1B, Symposia: Fluid Mechanics (Fundamental Issues and Perspectives; Industrial and Environmental Applications); Multiphase Flow and Systems (Multiscale Methods; Noninvasive Measurements; Numerical Methods; Heat Transfer; Performance); Transport Phenomena (Clean Energy; Mixing; Manufacturing and Materials Processing); Turbulent Flows — Issues and Perspectives; Algorithms and Applications for High Performance CFD Computation; Fluid Power; Fluid Dynamics of Wind Energy; Marine Hydrodynamics, 2016Ship-motion forecasting can be useful for naval operations such as aircraft landing, cargo transfer, off-loading of small boats, and ship “mating” between a large transport ship and smaller ships. The forecasted ship motion is particularly useful in sea states above SS3 when unanticipated large motions can suddenly occur.

Effect of ship motion on ship airwake aerodynamics
2020The effects of ship motion on the flow field over the deck of the ONR Tumblehome geometry were investigated experimentally. Characterization of the flow field is relevant in the context of safe aircraft operation in the wake region and to provide an accurate prediction of aircraft air-loads in simulators for pilots, and to provide a validation data set

A ship motion simulation system
Virtual Reality, 2008In this article, efficient computational models for ship motions are presented. These models are used to simulate ship movements in real time. Compared with traditional approaches, our method possesses the ability to cope with different ship shapes, engines, and sea conditions without the loss of efficiency. Based on our models, we create a ship motion

Real Time Ship Motion Estimation
OCEANS 92 Proceedings@m_Mastering the Oceans Through Technology, 2005The problem of real time estimation of ship mo- tions is consided. The problem is viewed as a nonlinear adaptive estimation problem for partially unknown time- varying linear systems with non-Gaussian initial conditions. The adaptive Lainiotis partitiong approach is applied and com- parisons are made with the Kalman filter.

PAMM, 2004
AbstractThe ship capsizing problem is one of the major challenges in naval architecture. The criterion of the International Maritime Organization (IMO) regarding capsize stability is still not including dynamic loads. Existing mathematical models of ships taking into account all degrees of freedom as well as fluid–structure–interaction can hardly be ...

Offshore Technology Conference, 1976
ABSTRACT When operating large ships in water depths only slightly greater than the draft, as super tankers at near-shore terminals, it is necessary to know precisely how much clearance is required for safety. Recent developments in hydrodynamics are applied to determine the motions of a ship due to waves and current

From the practical perspective, with large-scale cargoes or nonnegligible hook masses, the centers of gravity of cargoes and hooks do not coincide with each other, and shipboard cranes usually exhibit complex double-pendulum effects during ship-to-ship ...
