Structural strength is becoming a key issue in marine transportation. A Semi-Small Water-plane Area Twin Hull (SWATH) ship is a combination of a SWATH ship and a conventional catamaran. Due to twin hull design, the strength analysis is most important especially in transverse direction to prevent from structural failure in the middle location. This research introduced a complex finite element analysis, focused on evaluating the strength o f transverse Semi-SWATH bulkhead compartment beam structure. The early findings for finite element analysis are able to compute the critical stress of SemiSWATH structure especially in transverse direction. The results were compared with scale down experimental and good agreements are found.
