In this study, uncertainty analysis based on ITTC(International Towing Tank Conference) Recommended Procedures is carried out in thetowing-tank experiment for motion responses and added resistance. The experiment was conducted for KVLCC2 model in head seacondition. The heave, pitch and added resistance were measured in different wave conditions, and the measurement was repeated upto maximum 15 times in each wave condition in order to observe the uncertainty of measured data. The uncertainty analysis was carriedout by adopting the ISO-GUM(International Organization for Standardization, Guide to the Expression of Uncertainty in Measurements)method recommended by ITTC. This paper describes the details about the analysis method, uncertainty and the measured uncertaintyfor each source. The uncertainty analysis results are summarized as a tabular form. To validate the accuracy of the presentmeasurement, the experimental results are compared with the results of numerical computation and other experiment. From the presentuncertainty analysis, the main sources of uncertainty are identified, which can be very useful to improve the accuracy for addedresistance experiment.
