Computational techniques and empirical data do not yet allow determination of a mathematical manoeuvring model for a specific ship in rather extreme conditions, such as harbour manoeuvres in very shallow and restricted water. Therefore, experimental techniques, and in particular the execution of captive manoeuvring tests, will keep fulfilling an important task for several purposes. Time consuming series of stationary model tests are compared to alternative non-stationary captive model tests during which several test parameters are varied continuously with the view to obtaining all information needed in a limited number of test runs. Considering the difficulties related to the determination of mathematical models for the simulation of harbour manoeuvres, the authors intend to report on a first evaluation of the possibilities and limitations of these alternative captive model tests, rather than presenting a completely innovative PMM test procedure.
