Vessel Maneuvering Simulation.

Abstract

Ship maneuvering motion equations were formulated to evaluate maneuvering performance in standard maneuvers, stopping maneuvers, and harbor entering maneuvers with inclusion of various forcing functions such as those due to rudders, propellers, water depth, and control (i.e., autopilot or helmsman). Utilizing available hydrodynamic data and theories, the hydrodynamic coefficients in motion equations were evaluated for a typical medium-size tanker. Subsequently, simulation experiments were carried out for standard maneuvers and compared with available full-scale trials of a similar type tanker. Encouraging correlations were indicated between predictions and full-scale trials of a similar type tanker. Encouraging correlations were indicated between predictions and full-scale test results. Furthermore, harbor-entering maneuvers were carried out on a digital computer for the case of New York Harbor entering into Kill van Kull from New York Bay. Results demonstrate that this computational procedure is a useful tool to promote harbor traffic safety, although further refinement should be made to achieve realistic modeling of the ship-waterway systems.
