... Abstract Vortex-induced vibrations (VIV) are induced on a bluff body when it is introduced to a fluid flow, which produces vortex shedding. Many times, the presence of VIV attributed due to vortex shedding is considered undesirable since it leads to fatigue induced damage on structural elements...

... directions under a low damping ratio of 0.01 and a mass ratio of 6.9. The results of this study will provide valuable insight and aid the development of passive suppression devices for deep-sea structures. vortex-induced vibrations splitter plate passive suppression circular cylinder Proceedings...

... Abstract Vortex induced vibrations (VIV) of a flexible dynamic power cable in lazy wave configurations were investigated experimentally to understand their behaviour under currents of various magnitudes. The preliminary study investigates the effect of increasing current magnitudes in the range...

... Abstract This paper discusses some of the results and observations that were made in the Drilling Riser VIV and Wellhead Fatigue Joint Industry Project that was formed by a consortium of industry partners with the goal of studying wellhead fatigue that is caused by Vortex Induced Vibrations...

... 22 05 2009 Hydrodynamic interaction and clashing of two long flexible cylinders in uniform steady current have been studied. Model tests have been performed in the towing tank at Marintek in Trondheim. The riser models were free to move in vortex induced vibrations (VIV) and wake...

... 04 03 2009 Vortex Induced Vibrations (VIV) of elastically mounted rigid cylinders, with low mass-damping parameter values, are strongly dependent on the added mass coefficient. This paper aims to contribute to the technical literature by presenting some results from experiments carried...

... 09 01 2009 Vortex-induced vibrations (VIV) of slender structural elements (marine cables, pipes and risers) are very important aspects to be considered in the design stage of many offshore structures, because the fatigue life of risers installed in deep water are often dominated by VIV...
