6.2.2 Large Vessel No. 11<br />
Subsequently Vessel No. 11 is analysed in <strong>the</strong> same way. Its main dimensions can be found in<br />
appendix A.11. The oating condition shown in table 6.7 is set for Vessel No. 11. The KG<br />
<strong>and</strong> <strong>the</strong>refore <strong>the</strong> GM solid are again r<strong>and</strong>omly varied in <strong>the</strong> range <strong>of</strong> GM solid CE <strong>of</strong> <strong>the</strong> Chicago<br />
Express during <strong>the</strong> accident. The displacement, drafts <strong>and</strong> trim in this oating condition are<br />
kept constant. They also comply with <strong>the</strong> values <strong>of</strong> <strong>the</strong> Chicago Express in its accident .<br />
The resulting compilation <strong>of</strong> loading conditions, consisting <strong>of</strong> <strong>the</strong> mentioned oating condition<br />
<strong>and</strong> a varied GM solid value, is <strong>the</strong>n used to determine <strong>the</strong> respective <strong>seakeeping</strong> behavior.<br />
