Abstract

Non-linear mathematical models of ships comprise one hundred parameters or more, and differences between full-scale trials and model tests are difficult to associate with the individual terms. Direct identification of parameters would be advantageous. The paper employs a sensitivity approach in an attempt to achieve this. Using the method on full-scale data from a container ship, a good fit in roll and yaw is obtained, but the method reveals that this does not imply good determination of individual parameters. The sensitivity method is found to be easily applied for both identification and evaluation of the reliability of parameter estimates
