Figure 14: Stability curve<br />
According to the above printout from the shipboard computer (Fig. 13), the<br />
permissible longitudinal bending moments were exceeded in two places. They were<br />
exceeded by 11.4% at Frame 104 and 6.6% at Frame 125 and in formal terms the<br />
vessel should not have set sail.<br />
3.2.8 Investigation of the longitudinal strength, stability and roll oscillation<br />
In the course of the investigation, the BSU requested stability and trim calculations<br />
from the Institute of Ship Design and Ship Safety of the TU Hamburg-Harburg<br />
(TUHH) in order to clarify the following issues:<br />
• Did the vessel's stability due to the high GM value lead to the damage?<br />
• What options existed for the master to make the vessel softer and thus more<br />
steerable with the existing ballast water tanks?<br />
