DIGITAL SIMULATION ANALYSIS OF MANEUVERING PERFORMANCE
This paper presents results obtained in a series of digital simulations in the area of standard maneuver motion predictions, hull form design, control systems design, and maneuvering control in narrow channels. Hydrodynamic data obtained in captive model tests were used to achieve a realistic modeling of ship dynamic systems. Encouraging correlations are shown for the case of a typical large tanker between digital simulations and available full-scale trial data obtained in various maneuvers, including highly nonlinear ones such as enter-a-turn with a 40-degree rudder angle and emergency stopping from the design speed. Effects of inherent dynamic instability due to wide full-form configurations are examined in digital simulations as well as eigenvalue analysis. Results indicate that a ship with a large degree of inherent instability requires a relatively high sensitivity feedback in yaw-rate to achieve directional stability. Evaluation of maneuvering performance at the design stage is recommended particularly for full-form configurations.
