![]() ![]() So the fundamental method of producing these shapes is an interesting example of reverse engineering.įigure 1: Production of non-developable surface Non Developable Surface: These are 3D surfaces which cannot be achieved by direct rolling or hydraulic bending of straight plates. ![]() There are two basic types of 3D geometries: To bend and develop steel plates and stiffeners to required 3D curvatures in order to make them fit the shape of the hull, special methods are used by a shipyard.īefore understanding these processes, it is important to appreciate two very important aspects of developing curved surfaces. It might seem quite easily achievable on a 3D modelling software package, but production of the same is not. Plate BendingĪ ship’s hull usually has multiple curvatures (unless only straight plates are used in the design). Following surface preparation, machining of plates and sections are carried out in the hull shop where they are made ready to be welded into two dimensional and three dimensional structures. We will see how the plates and sections are given shape and curvature according to the design of the hull. This article will take the material flow forward. ![]() We also discussed the methods used to carry out the above processes. In the last article we discussed how material is shifted from the stockyard to the surface treatment plant, then marked, nested and cut to required shapes. ![]()
