Strength Analysis of a RO-RO SWATH Ship Deck Layout

The purpose of the paper is to obtain the loads that occur in the connecting deck of a multihull ship, considered on a beam wave. Therefore, is written and used a macro command for obtaining the displacement distribution in order to simulate the bending generated by the beam waves loading. A strength analysis of the loaded connecting deck layout is also performed, to obtain the loads that act upon the structure. In order to determine the stress hot spots and to compare the stresses to the yield point, a linear static analysis is considered.
