COMPARISON OF SELECTED PARAMETRIC METHODS FOR PREDICTION OF INLAND WATERWAYS SHIP HULL RESISTANCE IN TOWING TANK TEST

Abstract

In the paper selected approximate methods for calculation of inland waterways ship resistance and their verification by towing tests, compared on the example of a small urban ferry, are presented. The test results are made for both the bare hull and the hull with appendages (skeg, azimuthal propeller). Significant differences between results of the theoretical methods and experimental ones, especially in the case of the model with skegs and propulsion, are pointed out. The purposefulness of using several parametric methods and the use of average results at the preliminary design stage were also discussed.

Keywords:

ship resistance, inland waterways
