For the sake of easy fabrication, hull structure has been usually composed of uniform members which are arranged in regular position. For instance, side frames, stiffeners of panel and web frames have uniform cross sectional shapes in way of span and are arranged in equal spacing. The thickness of steel plate, which composes a hull structure, is also uniform in a certain limited part. These uniformities have brought the advantage of easy fabrication under the conventional production systems. However, it has recently become not important for easy fabrication to keep these uniformities when modern high self-controlled automatic instruments are applied. In some cases, more rational design can be attained by introducing non-uniformity into the hull structure. In this paper, authors have introduced some applications of non-uniform thickness steel plate into ships hull structure as shown as followings. 1) Stiffened Panel 2) Longitudinal Frame with Tapered Thickness Face Plate Plate thicknesses in these applications are varied with sine-curve shape in one direction to keep the uniform strength in accordance with the stress distribution. The design concept would aim at not only the uniformity of structural strength but also saving of material at the same time. In the application to the actual ships, there would be some problems such as the productability, the conformation to rules of classification societies and correlation with another requirement in design factor. However, it is expected to be not so far future that the hull structure composed of the introducing non-uniform thickness steel plate would be realized if only a proper part would be selected for application.
