Vessel No. 06 has the geometric capacity to carry 4, 253 T EU . Having the main dimensions
according to table 4.11, it is another midsized container vessel which may travel through the
Panama Canal. The following characteristics of Vessel No. 06 are to be noted:
ˆ The lines of the ship shown in gure 4.11 have a c B value of 0.61 on design draft.
ˆ The bilge keel area is not documented for this vessel and is estimated according to chapter
3.9.
ˆ The stability in ballast arrival loading condition is moderately high resulting in a
GM solid = 7.47 m.
ˆ The limiting intact stability criterion (Max. GZ at 25 ◦ ) requires a GM min = 1.33 m.
The calculated transversal accelerations on the bridge and the rolling angles for the three accident
conditions are listed in table 4.12.
