Uncertainty analysis of resistance tests in ata nutku ship model testing laboratory of istanbul technical university

In this study, some systematical resistance tests, where are performed in Ata Nutku Ship Model Testing Laboratory of Istanbul Technical University (ITU), includes transactions in order to determine the uncertainties. Experiments which are conducted in the framework of mathematical and physical rules for the solution of engineering problems, measurements, calculations include uncertainty. To question the reliability of the obtained values, the existing uncertainties should be expressed as quantities. The uncertainty of a measurement system is not known if the results do not carry a universal value. On the other hand, resistance is one of the most important issues that should be considered in ship design process. Ship resistance during the design phase of a ship cannot be determined precisely and reliably due to the uncertainty resources in determining the resistance value that are taken into account. This case may cause negative effects to provide the required specifications on the latter design steps. The uncertainty arising from the resistance test has been estimated and compared for a displacement type of a ship according to ITTC 2002 and ITTC 2014 regulations which are related to the uncertainty analysis methods. Also, the advantages and disadvantages of both ITTC uncertainty analysis methods have been determined.
