Abstract

The aim of this study is.to decrease naval TRIMARAN weight by optimizing CROSSDECK structural elements under SPLITTING MOMENT in the finite element software. Adding sidehulls to mainlhull improves seakeeping and behavior of vessel in waves. In addition, because of asymmetry pressure acts on vessels, designing of CROSSDECK, especially under big angle of effect, is very important. So in this article, the loading of waves is obtained according to Lloyd’s register by using some assumption and simplification. The initial structural design of vessel is done based on some requirements provided by Lloyd’s register. Based on the research conducted on this issue, the hulls and elements of TRIMARAN are simulated with uncomplicated geometry. Before solving the main problem, the present experimental method is validated by comparing with another authentic article. Furthermore, validation process, meshing details and the problem solving results are presented in detail. numerical analysis has shown that structural elements variation could lead to the decrease in the vessel weight. Accordingly, a decrease of 3% in weight based on the change of cross deck structural elements is presented as a result of this study, as an achievement is obtained.
