ESTIMATION OF MANOEUVRING QUALITIES FOR ACTUAL SHIPS BY MODEL TESTS
The Authors discuss techniques for estimating the manoeuvring properties of ships from model tests, and, to solve the difficult problem of scale effect in such predictions, propose two model-test techniques. In one of these, a free-running model with a length of about 15 m is used; the other technique, in which a planar motion mechanism is employed, uses a captive model about 3 m long. The use of a large model for the free-running tests, and the incorporation of improvements in the captive-model technique (for example, by choosing an adequate swaying or yawing frequency), should solve the scale-effect problem. The manoeuvring characteristics, for three large full-form ships, estimated by these model techniques agree well with those determined in full-scale tests, so confirming the Authors' views.
