Statistical Analysis of Performance Test Results

Jan Holtrop
6 pp.

A statistical evaluation of model and trial test results, selected from the archives of the Netherlands Ship Model Basin, was carried out using multiple regression analysis methods. The objective of this study was to develop a numerical description of the ship's resistance, the propulsion properties and the scale effects between the models and the full size. The most important applications of the obtained results are the determination of the required propulsive power without doing specific model tests and further the refinement of the extrapolation method by which model test results are scaled up. The evaluation was performed by applying multiple regression analysis to the results of 1707 resistance measurements, 1287 propulsion measurements carried out with 147 ship models and the results of 82 trial measurements made on board 46 new ships.
