• Abstract

  The VIM - vortex-induced motions phenomenon is a particular way to call VIV - vortex-induced vibrations. VIM occurs in offshore platforms due to current incidence. Motions in the transverse direction are in the same order of the platform main dimension. These large amplitudes in the horizontal plane are responsible to decrease the fatigue life of the mooring and riser systems, therefore V…

• Abstract

  The ow around yawed cylinders, or oblique flow, is a common problem in several engineering conditions. An example of offshore application consists on the flow around risers hanged in catenary. A more recent example of application is the ow around the columns of a Tension Leg Platform (TLP). Despite the fact that the ow around a nonyawed cylinder consists on a extensively studied problem w…

• Abstract

  The subject of this work is the study of fluid-structure interactions of rigid and flexible circular cylinders, in number of one and two, similar to risers, by means of experimental and numerical approaches. The main objective is the study of Vortex-Induced Vibrations in such conditions. The student is supervised by Prof. Dr. André Luís Condino Fujarra, of the Departament of Naval Archite…
