Interactive Simulation of Ship Motions in Random Seas based on Real Wave Spectra
نویسندگان
چکیده
The current paper presents a methodology to compute and represent the ship motions at interactive frame rates, when navigating on a virtual sea defined by a real wave spectrum. The Inverse Discrete Fast Fourier Transform algorithm is used to compute the sum of all ship motions components induced by the waves and get the final irregular ship motion. Currently, this is the most efficient method to simulate the ship motions in interactive ocean simulations using wave spectra to describe the sea states. The visual realism and physical accuracy of the simulations turns this method into a powerful tool for developing interactive ship

Numerical Simulation of Random Irregular Waves for Wave Generation in Laboratory Flumes
Understanding of wave hydrodynamics and its effects are important for engineers and scientists. Important insights may be gained from laboratory studies. Often the waves are simulated in laboratory flumes do not have the full characteristics of real sea waves. It is then necessary to present reliable methods of wave generation in wave flumes. In this paper, the results of numerically simulate...
متن کاملRisk and Simulation-based Optimization of Channel Depths: a Case Study at the Entrance Channel of Cam Pha Coal Port
This paper presents a new simulation model for long-term optimization of channel depths in which the risk of ship grounding due to wave impacts can be considered for every ship transit. This new model includes four main components: (1) an exponential probability law for a number of ship departures; (2) a parametric model of the wave-induced ship motions; (3) modeling effects of tidal variations...
متن کاملRANS Computational Fluid Dynamics Predictions of Pitch and Heave Ship Motions in Head Seas
This work extends the previous effort in unsteady Reynolds averaged Navier-Stokes (RANS) simulations developed by the ship hydrodynamics group of the University of Iowa Iowa Institute of Hydraulic Research to the capability to predict pitch and heave motions of ships with forward speed in regular head seas. The simulations are performed with CFDSHIP-IOWA, which is a general-purpose, multiblock,...

For stabilization of zero speed ships active anti roll tanks and gyro stabilizers are used. Because of anti roll tank limitations on working frequencies gyro stabilizers are proposed. A nonlinear model for ship is used to simulate hydrodynamic forces. Wave’s disturbances are considered as non-parametric uncertainty. A sliding mode controller is used for roll stabilizing. A nonlinear h infinity...
