FEM Structural Analysis and CAD Hull Modelling for a Bulk Carrier - a Case Study
1 Mircea cel Bătrân Naval Academy, Constanța, Romania
ABSTRACT: Due to the frequent damage encountered in the hull of bulk carriers in operation, it is necessary to analyse the possibilities to increse the performances by structural and dimensional modeling of the central area of the hull of the vessel under the effect of combined general stresses (and specific local stresses. The present paper analyzes the response of the central section of the bulk carrier of 165000 tdw for three representative cases of total stress, re-evaluated by simulation with the help of finite element analysis software. Following the interpretation of the results obtained by the finite element analysis, the authors propose some solutions to increase the structural strength of the central area of the bulk carrier of 165000 tdw. The present study shows that the structure of the cylindrical area of the hull of the analyzed ship, remodeled by finite element, ensures the compromise between the operational requirements and the design requirements imposed by the norms The structural characteristics of the central section of the ship were analyzed, the practical validation being provided by the finding that the bending moments do not exceed the permissible values imposed by the class society. Work was done on three separate cases of ship loading and corrections were made for 12 sections of the hull. The use of high-strength steel has led to a weight reduction of 22%.
