A Multidisciplinary Method for Evaluating Ship Stability

The aim of this paper is to present the main results arisen from the joint efforts of the public-private partnership in being between CCII (Centro Cultura Innovativa d'Impresa) of University of Salento and Apphia s.r.l.. This paper will focus on the results of the core of the OBSS (on board stability system) module that, starting from the exact 3D geometry of a ship hull, described by a discrete model in a standard format, the distribution of all weights onboard and the data acquired by the system, calculates ship floating conditions (in draught, heel and trim). The proposed approach is based on geometry meshes represented by an universally accepted file format (named OBJ) first developed by Wavefront Technologies. Demonstration of the validity of the results is done by the authors using as hull model a simple rectangular box.
