Análise estrutural de uma unidade portátil offshore por meio da modelagem não linear dos cabos de içamento

Abstract

The main operation in industrial enviroment is transportation, that is, the displacement of materials from and to the industrial plants as well as the displacement of materials inside of the plant. Normally the loads envolved are above of the human physical capacity, then lifting and transportation machinery is necessary. This machinery may work in onshore, offhore and subsea conditions. In this article, it was performed the structural analysis of the lifting of a portable unit of 1 cubic meter in offshore conditions, using the Finite Element Analysis (FEA). The geometrical discretization was performed using shell elements and the equations discretizations was performed using the Discrete Kirchhoff Theory (DKT). The model was constructed using the software Salome Meca considering the nonlienarity from the cables. It was obtained the maximum admissible load for the estructure, according to DNV 2.7-3.
