AbstractThis is the 2nd phase of a research program designed to develop a procedure for Experimental Uncertainty Analysis (EUA) for ice tank ship testing. The latter is a task for the 23rd and 24th ITTC specialist committee on ice. In this report, the results of Phase-II ship resistance in ice test program (IMD report TR-2003-07) were used to formulate the EUA procedure. The "total uncertainty" is the sum of a "bias uncertainty" and a "random uncertainty". Bias uncertainties are due to system set up and calibrations of equipments and instrumentation. Random uncertainties are associated with the degree of repeatability (accuracy) of the test results. Major sources for random uncertainties are model misalignments, effects of the surrounding environment (such as change in temperature during testing), human factors, ?etc. The procedure for EUA presented in this report validates the applicability of the preliminary EUA procedure (proposed by Derradji-Aouat, 2002) to the laboratory measurements from both phases of testing. Consequently, this EUA procedure will be recommended to the 24th ITTC (during its general meeting, Scotland, 2005).
