Pré e pós-processamento gráfico para análise global de risers e linhas de ancoragem

Abstract

This work is the result of the combination of Offshore Engineering and Computational Engineering knowledge ainnning to produce a group of pratical and efficient tools for the analysis of structural components used offshore by the petroleum industry. The engineering mathematical models used in this work, have been taken from previous work performed at the PETROBRAS. Hence, the basic philosophy behind this thesis was to enhance the ability to analyse such knowledge, by means of graphical pre and post processing, applied to offshore structures, mainly flexible risers and mooring lines, which are extensively used by PETROBRAS. As a result, two computacional systems providing for the pre and post processing of the ANFLEX [ 2,3 ] program, for analysis flexible risers, were implemented.
