Vessel No. 10 has the geometric capacity to carry 2, 478 T EU. Having the main dimensions
according to table 4.19, it is the smallest analysed vessel. In addition it is the only vessel equipped
with cranes and a deck house located at the ship's aft end. The following characteristics of
Vessel No. 10 are to be noted:
ˆ The lines of the ship shown in gure 4.19 have a c B value of 0.63 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 less high resulting in a GM solid = 5.95 m.
ˆ The limiting intact stability criterion (Area (0, 40) = 0.090 m · rad) requires a
GM min = 0.38 m.
The calculated transversal accelerations on the bridge and the rolling angles for the three accident
conditions are listed in table 4.20.

The maximum acceleration of 14.5 m /s 2 occurs for accident situation 2 while the associated
rolling angle of 43 ◦ is the highest calculated value in the whole examination. The statistical
distribution of the transversal accelerations in this situation is shown in gure 4.20.
