The paper presents an original computer based method used for the discretization of the ship hull cross sections, activity which is a part of a larger project -the ship hull analytical model. We started the discretization process with the so called 'typical sections'. The resulting 'templates' are useful because the parameterized analytical models may be reused for a particular frame which has particular dimensions, i.e. thickness of the side outer/inner shell plates. The section was divided

A sign which may be either +1 or -1 is assigned to each 'simple' shape in order to create a Boolean algebra. The specific data which define the 'simple' shapes was stored in spreadsheet documents where it can be easily identified, filtered and saved in CSV format in order to be loaded in the upper-level data processing application. We already created an application which lists the data included in a selectable CSV file in order to test the header files already developed in the 'calculus domains' software development project and to verify the correctness of the cross section discretization. The results are used to compute the weighting forces which are used to develop the loads' model. The discretization is also useful to compute the geometrical characteristics of the sections to be used in the calculus of the stresses and of the displacements.
