1 Technical Note of NILIM (2) Analysis of container ships by type (Under-Panamax 3) Over-Panamax type (Figure 3-49 to Figure 3-52). Panamax Over-Panamax) Loa, Lpp, B, and D, were analyzed by the average In Figure 3-10, the B analysis diagram for DWT, B is value analysis method, with the following classification a constant value of about 32m from approximately set for ships of 55,00 DWT and higher. 30,000 DWT regardless of the increase of DWT, and over 55,000 DWT or higher, less than 65,000 DWT. 50,000 DWT, it clearly rises discretely. This is caused by 65,000 DWT or higher, less than 75,000 DWT. restrictions on overall width of ships passing through the 75,000 DWT or higher, less than 100,000 DWT.

If B does not reach approximately And in the case of the Over-Panamax type, Table 3-6. 32m, it is called Under-Panamax type, and if it exceeds presents the one-fourth value (25% value) and the approximately 32m, it is called Over-Panamax type. three-fourth value (75% value) when, instead of statisti- Therefore with B = 32 m as the threshold, they are cal analysis results, the dimension for each ship class are analyzed in three types: Under-Panamax, Panamax, and aligned in rising order.

Both Loa and Lpp were analyzed by the logarithmic regression analysis method, obtaining R2 = for Loa and R2 = for Lpp. ii) B (Figure 3-47). B was analyzed by the average value analysis method. iii) d (Figure 3-48. d was analyzed by the linear regression analysis method, obtaining R2 = Table 3-4 shows the results of analysis of each main dimension according to the ship class that was set.
