    It is the purpose of this paper to present a current research project at Odense Steel Shipyard Ltd., Denmark. The objective of the research is to find new mathematical methods for the design of shell plates and apply these methods at the shipyard. The focus is on double-curved plates as they are the most difficult to design and produce, and often gives rise to gaps in the final assembly stage requiring great expenditure of efforts to rectify.The project aims at approximating a double-curved surface with a (developable) cylinder surface using a new method for approximation. By use of the Gaussian image of a given surface, we determine a projection plane. In the orthogonal projection of the surface onto this plane, a reference curve is determined by use of methods for thinning of binary images. The cylinder surface then can be derived with its directrix in the projected area and rulings perpendicular to the projection plane.Application of the results will be used to analyse the plate layout for production and suggest better alternatives, and thereby minimize the heat input.
