For Container ships, the number of Twenty-foot Equivalent Unit(TEU) containers have been used as a characteristic metric of size. For Cruise ships and Ro-Ro Ferries, the size is determined by Gross Tonnage(GRT) measurements. For the remaining ship types, the Dead weight(DWT) was used for determining ship size. The distribution of values shown in Fig. 8- Fig. 16 are percentile graphs that indicate the full range (minimum to maximum) for each characteristic metric and show the dispersion of values. The graphs depict 50% of all values within the rectangle, which is bounded by the 25th and 75th percentiles and indicate the median of the sample as a line. The dashed horizontal lines indicate the limits of the various size classes per ship type, as defined by the Clarkson's Intelligence Network. To identify potential changes in the distributions, the following figures also compare the accident sample including extreme weather events (N = 277) with the accident sample containing only heavy weather conditions (N = 239). The comparison shows that the distributions indicating ship size and in-stalled power are not observably different if we exclude extreme weather events from the analysis. This will be further elaborated upon in the section presenting the analysis of the prevailing weather conditions.
