Simulation of Ship Motion in Seaway
Accurate modelling and simulation of ship motion in seaway is essential to test applications of ship motion control strategies. In this report, we review the mathematical description of ocean waves, and their effect on the motion of marine vehicles. We present a simple method suitable for accurate simulation that incorporates parameters related to the recommended spectral family and particular ...
متن کاملNumerical Simulation of Damaged Ship Motion in Waves
The coupling motion of heave, pitch and roll of intact ship and damaged ship in waves, and the flow of flood water in damaged tank have been simulated based on viscous theory. The calculation model is a 29000 t tanker model moving at a constant speed with damaged tank in midship area. Three cosine waves including head waves, beam waves and oblique waves are simulated by boundary input method re...
متن کاملHeavy Weather Ship Handling Simulation With and Without Motion
Despite the fact that high risk sailing operations are often caused by heavy weather and characterized by vigorous ship motions, the vast majority of (full mission) bridge simulators are Earth fixed. We therefore evaluated the value of adding motion to ship simulation in terms of technical feasibility, measurability of performance, and effects on training. Of eighteen navy personnel, nine recei...
متن کاملA Nonlinear Ship Manoeuvering Model: Identification and adaptive control with experiments for a model ship
Complete nonlinear dynamic manoeuvering models of ships, with numerical values, are hard to find in the literature. This paper presents a modeling, identification, and control design where the objective is to manoeuver a ship along desired paths at different velocities. Material from a variety of references have been used to describe the ship model, its difficulties, limitations, and possible s...
متن کاملShip Roll Motion Control
The technical feasibility of roll motion control devices has been amply demonstrated for over 100 years. Performance, however, can still fall short of expectations because of deficiencies in control system designs, which have proven to be far from trivial due to fundamental performance limitations. This tutorial paper presents an account of the development of various ship roll motion control sy...
