Uncertainty Analysis for Ship Maneuvering in Model Scale and Full Scale Measurements

In this paper the uncertainty analysis (UA) of the coefficients present in 4 DoF modular maneuvering mathematical model (Hull + Propeller + Rudder) has been done by considering error in data measurement and mathematical model. Asymmetric behaviour of rudder forces of starboard and port side rudder was analyzed. All relevant maneuvering coefficients were calculated from respective PMM tests and verified with available literature. There are sources of errors in data measurement, model structure, model algorithm, etc which are still to be analyzed. The DTMB 5415 was selected because of its added complexity due to twin-propeller twin-rudder configuration.
