Abstract : 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)
