Abstract

The objective of this study is to analyze the global structural strength of a pleasure yacht by advanced FEA approach. This is accomplished by developing and implementing a user FEMAP API script for equilibrating the FEA ship model, in calm water and sagging and hogging wave conditions, for different wave design heights, up to a maximum height of 6.5 meters. The FEA strength is assessed by yielding stress and buckling criteria.
