Abstract

FEM models extended on a portion of the ship’s length, with ship - wave balancing parameters calculated using the equivalent beam model, are suitable for the ship’s body strength analysis in areas where global stresses are dominant, respectively for the central areas of cargo compartments. The purpose of this paper is to verify the induced stresses of a framework element from central area of the chemical tanker ship type. This static calculation was performed by the finite element method with Femap software as modeller and NX Nastran as solver.
