Desenvolvimento e aplicações de um framework orientado a objetos para análise dinâmica de linhas de ancoragem e de risers

Abstract

This work is motivated by the increasing demand that has been stimulated by the oil industry for complex computational systems which are capable to simulate the physical behavior of offshore structures. Computational systems available for dynamic analysis of mooring lines and risers have some limitations for including new implementations. The extension of these codes is possible, though. However, many times the incorporation of new functionalities to these systems demands hard work to implement new functionalities. Moreover, an initial effort is needed for the understanding of code. A framework for geometrically nonlinear dynamic analysis of mooring lines and risers is built to increase the efficiency in the development of these systems. This framework facilitates understanding, reuses, extension and maintenance of code. In addition, this work shows the main aspects that guides framework development, such as the physical problem modeling, important computational concepts, validation of framework through applications and contributions most important of this work.
