Structural Finite Element Method (FEM) analysis provides a solid basis for evaluating the structural behavior of ships and contributes directly to the identification of critical areas in terms of strength and design validation. Inconsistent and non-compliant design can result in operational risks, high maintenance costs, early degradation, or even structural collapse. The present study aims to evaluate the overall structural behavior of a 1400 TDW inland navigation barge under real operating conditions, during ballast and full load navigation, both in calm water and under design-equivalent wave loads. The wave height of 1.2m was considered as imposed by the navigation area. To enable an effective evaluation that accurately reflects the barge’s actual condition, the 3D FEM model represents the idealized structure of the barge with average element size of 200mm. The model equilibrium was achieved using Orca3D software. The results were assessed based on the Von Mises criterion and the maximum deformation values, allowing for the identification of regions with increased risk in terms of structural strength.
