Abstract

The study of the phenomenon of vortex-induced vibrations (VIV) is very important in the offshore industry, when risers, pipelines and platforms, all in cylindrical metallic structures, vibrate when there is a passage of the marine current. The marine current becomes the determining factor as oil exploration in deep waters, and these cilindrical structures are subject to cyclic loading situations that significantly reduce their useful life due to fatigue. Thus, this article shows a test done in a current channel and comparisons with a commercial program widely used in the oil industry called SHEAR7® and a finite element program called ANSYS®. A brief explanation of the programs will be presented, and the test performed with the cylinder. The purpose is to predict and compare, as close as possible to that observed in the channel, the displacements of rigid cylinders, proving that today there are tools on the market that demonstrate the complex phenomenon that are vibrations caused by vortices
