Uncertainty Assessment of Free-running Maneuvering Model Test for Surface Ships

Free-running maneuvering model tests of surface ships are important to assess the maneuvering performance of ships. As one part of model test data analysis, uncertainty analysis is performed to estimate model test results. But the method of uncertainty analysis has not been well established for free-running maneuvering model tests. In this study, based on ITTC recommended procedures and guidelines (2008a) and adopted with the ISO-GUM method, uncertainty analysis for free-running maneuvering model test was conducted. Uncertainty analysis of free-running model test for the YUPENG ship, including turning test and zig-zag test, was given in the paper. © 2021, Editorial Office of Ship Building of China.
