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

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

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 ...

3D Simulation of Ship Motions to Support the Planning of Rescue Operations on Damaged Ships
Procedia Computer Science, 2015 The paper describes a software system to simulate the ship motions in a crisis situation. The scenario consists of a damaged ship subjected to wave excitation forces generated by a random sea state.

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.

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

Resistance of a Ship Undergoing Oscillatory Motion
Journal of Ship Research, 2010In this paper, we describe extensions to the research of Doctors et al. (Doctors, L. J., Day, A. H., and Clelland, D., 2008, Unsteady effects during resistance tests on a ship model in a towing tank, Journal of Ship Research, 52, 4, 263–273) and Day et al. (Day, A.

The motion of a ship at sea and the consequent motion sickness amongst passengers
Ergonomics, 1986Measurements were made of the motion of a ship, and of the consequent seasickness experienced by passengers. Data are presented for 17 voyages of up to 6 hours duration, involving 4915 passengers. Vertical motion occurred up to 1·0 m s−2 r.m.s. and vomiting incidence of up to nearly 40% was encountered.
