Abstract: Acceptable steel structure scantlings are mandatory during the early design process. For merchant ships the designer has to fulfill the structural constraints posed by the Classification rules. However, the tools provided by the Classification societies are not well adapted to the early design process where frequent changes to all ship design parameters are crucial. For this purpose, we have created a link between the ship design system E4 and the DNV rule scantling tool Nauticus Hull. The link allows for seamless exchange of scantlings information and quick assessment of Class conformity thereby reducing time spent on the steel iterations. The link is demonstrated through the application to a Ro-Pax design. For the scantlings the focus is on rough weight and strength estimation as well as assuring class conformity. A more flexible and comprehensive data exchange is achieved by working directly with the XML storage format of Nauticus Hull.
