Abstract
In the existing whole ship analysis, topside was modeled as mass element. However recently, the topside is modeled as beam element due to the owner’s requirement to improve the maturity of the whole ship FE model. To follow the owner’s requirement, detailed information for topside drawing and modeling, which may delay analysis schedule, is needed. However, it is hard to respond effectively to this matter due to the lack of study on the topside from the hull perspective. Therefore in this study, the effect of the topside on the hull is investigated when the topside is modeled as a mass element or beam element respectively. In addition, the interface modeling method is analyzed to verify modeling method used in the existing whole ship analysis. The results indicate that the interface and topside modeling method used in existing whole ship analysis are appropriate. This conclusion will be the technical basis for responding to owner’s requirement about the topside modeling method.
