EHP VALUE OF MINI LNG SHIP WITH FORM FACTOR FROM PROHASKA AND IRLS METHOD USING SHIP RESISTANCE TESTING DATA

The ship model test was believed to be one of the effective methods for figuring out boundaries and reliability ship's horsepower. form factor determines a full-scale Determination value can done experimentally through Prohaska method. new method proposed in this study is employed regression Iteratively Reweighted Least Squares (IRLS) by utilizing principle dimension ship, such as LWL, B, CB, CP, CM, WSA, T, ∆. etc. Indonesian Hydrodynamics Laboratory has database ships with various dimensions which have undergone towing test. Through database, predicted IRLS then verified validated result shows good agreement obtained results from also show that EHP & Resistance calculations are identical old fashion methods. residual bias established comparison generated Comparison between two small error.
