An attempt is made to extend ship-maneuvering analysis for application at low ship speeds. Captive-model experiments are made to investigate effects of non-equilibrium propeller speeds on rudder force and effective thrust. Other experiments are made to explore first-order effects of very large drift angles and pure yaw rotation on hull hydrodynamic reactions. The experimental results, together with previous rotating-arm data, are applied in motion equations, accounting for both extreme propeller actions and the occurrence of large drift angles and turning rates. Also included are propulsion and rudder time lags, and the influence of uniform water current on ship trajectory. The equations are programmed for computation, and ship response to a simple docking maneuver is predicted. The computation is repeated several times to examine sensitivity of ship motions and trajectory to variations of operating parameters, namely, maximum reverse propeller speed, engine response time, and water-current direction.

In the traditional approach to the problems of ship maneuvering, on uses a set of linearized equations of motion that excludes the possibility that the hydrodynamic forces and moments might be affected by the history of the motion. Using ideas introduced by Cummins, one can obtain another linearized set of the equations of motion which contains a 'memory function' as well as the added mass and damping coefficients. These stability coefficients have been evaluated by an impulse-response techniques, a method that is new to ship maneuvering problems and that appears to represent a substantial improvement over the traditional regular-oscillatory-motion tests. Results from both experimental methods are presented for comparison. To examine the effect of the memory function upon predictions of standard ship maneuvers, predictions of a few standard maneuvers have been calculated using both sets of the linearized equations of motion. The differences between the predicted motions were found to be small for all the cases we examined. (Author).

A ship maneuvering motion procedure has been developed to be used in a vessel safety model, utilizing experimental data obtained in free-running model tests. Ship trajectories in terms of steady turning rate, advance, and transfer can be determined as functions of ship length, draft, beam, rudder area, rudder angle, and water depth. Furthermore, speed reduction due to turning can be computed as a function of ship hull parameters and turning rate. The effectiveness of the harbor navigation model is indicated by fairly good agreement between predictions and actual data points. Basic equations of ship maneuvering motion and a summary of existing hydrodynamic data in this area are also presented. (Author).
