Abstract
Ship maneuvering affects many aspects of naval ship performance, including collision avoidance, safety against capsize, and defence against hostile forces. Predictions of ship maneuvering can also be useful for design, training, and operational planning. This report compares predictions of turning circle parameters made by a ShipMo3D application called HalManeuver, and predictions from the FREDYN program, with maneuvering trials data for HALIFAX. The intent is to establish the limits of accuracy of these models, which are state-of-the-art tools for ship motion prediction. It also identifies the range of uncertainty associated with the specific HALIFAX models. The comparison shows that the FREDYN model is usually more accurate in terms of smaller mean and maximum error values. However there are many modeling uncertainties that could affect the comparison, and it is reasonable to say that both codes provide comparable results if model parameters are chosen carefully.
