Analysis of global and local strength using 3D FEM models extended over 3 cargo holds of a 47600 dwt chemical tanker
Keywords:
chemical tanker, finite element method, stress concentration, structural strength analysis, global and local strength, hull girder structure, ship structural integrity.
Abstract
This study examines both the local and global structural strength of a 3D finite element model (FEM) representing the three cargo holds of a 47600-DWT chemical tanker. Vessels of this type require a detailed assessment of their structural behavior under extreme loading conditions as well as routine operational demands. The analysis of stress distribution and structural strength enables the identification of critical areas within the hull,
providing essential insights for enhancing the vessel’s structural integrity and overall performance.
