The KBXM ship hull structure

The paper deals with the outline analysis of the transitional types of the double skin side hull structures between the "Classical" and the "Unidirectional Girder System" duble skin hull structures. The KBXM family of structures, as a result of the analysis, are defined as the three layers structures. The first layers are shell platings, the second ones are longitudinals of inner and outer platings and the third one consists of the transversal/longitudinal distant members. That enables high technological performance of the KBXM structure family, nearly equal to the "Unidirectional Girder System" type of structure, what was the first research aim. The KBXM structures are expected to be nearly equal in weight to the "Classical" type of structure, what was the second aim. The further research activities on the KBXM hull structures are also defined.
