Contribution to Conference
In this study, the peak-over-threshold method is applied to investigate the influence of the threshold used in the statistical analysis of sloshing loads. Weibull distribution, generalized Pareto distribution, and log-logistic distribution are used to the statistical analysis. In addition to the previously used moment method, the parameters of distributions are estimated using the L-moment method and the maximum likelihood function estimation. Statistical analysis is performed based on the experimental data obtained from 20 repeated experiments of 5 hours in real scale. In order to compare the results between statistical models, the probability plot correlation coefficient and the 3-hour most probable maximum are used. The results of this study can be one of the indicators for the statistical analysis for sloshing load prediction according to experimental conditions.
