Desain Konstruksi Kapal Katamaran Tipe Axe Bow Lambung Asimetri

A catamaran is a type of multihull vessel consisting of two hulls connected by a bridging structure and has structural characteristics that differ from those of a monohull vessel. This study discusses the structural design of an asymmetric-hull Axe Bow catamaran based on predetermined principal dimensions. The purpose of this study is to determine the dimensions of the ship's structural elements, including plate thickness, stiffeners, structural profiles, and connecting structures between the two hulls, in accordance with the rules of Biro Klasifikasi Indonesia (BKI), and to produce a three-dimensional structural model as a representation of the proposed structural design. The research method includes a literature review, collection and processing of the vessel's principal data, material selection, determination of material factors and speed correction factors, calculation of design loads, determination of plate thicknesses and section moduli of structural elements, and three-dimensional modeling using Rhinoceros 3D. The structural design employs Aluminium Alloy 5083-H116 in accordance with the applicable BKI requirements for ship structural design. The calculation results are used to determine the dimensions of plates and structural profiles, which are subsequently implemented in the three-dimensional model. The results of this study consist of the structural design of an asymmetric-hull Axe Bow catamaran, including hull and deck plating, transverse frames, longitudinal frames, web frames, floors, girders, deck beams, cross-deck structures, and other supporting structural elements. The resulting three-dimensional model illustrates the overall arrangement of the structural elements and can serve as a basis for preparing structural drawings and for further development of the structural design of an asymmetric-hull Axe Bow catamaran.
