The results listed in table 6.8 show, that Vessel No. 11 at rst does not experience excessive
transversal accelerations . However for GM solid = 9.28 m a slightly maximum for the transversal
acceleration of 5.5 m /s 2 is already considered to be noticeable. So for this specic sea condition
within accident situation 1, a GM solid value of about 9 m leads to the highest, but insignicant
accelerations.

Following from this result, another compilation of displacement, trim and GM should be
determined, where the constant excitation of the seaway results in high accelerations. For this
reason the vessel is immersed slightly deeper. The new oating condition shown in table 6.9 is
set. A new compilation of loading conditions is then created by varying GM in the same scope
as before.
