Mitigation of Vortex-Induced Motion, (VIM) on a Monocolumn Platform: Forces and Movements
(ASME-AMER SOC MECHANICAL ENG, 2010)
A great deal of works has been developed on the spar vortex-induced motion (VIM) issue. There are, however, very few published works concerning VIM of monocolumn platforms, partly due to the fact that the concept is fairly ...
Analysis Methodology for Vortex-Induced Motion (VIM) of a Monocolumn Platform Applying the Hilbert-Huang Transform Method
(ASME-AMER SOC MECHANICAL ENGNEW YORK, 2012)
Vortex-induced motion (VIM) is a highly nonlinear dynamic phenomenon. Usual spectral analysis methods, using the Fourier transform, rely on the hypotheses of linear and stationary dynamics. A method to treat nonstationary ...
Experimental comparative study on vortex-induced motion (VIM) of a monocolumn platform
(ASME-AMER SOC MECHANICAL ENGNEW YORK, 2012)
An analysis methodology is presented as well as a comparison of results obtained from vortex-induced motion (VIM) model tests of the MonoGoM platform, a monocolumn floating unit designed for the Gulf of Mexico. The choice ...
Experimental study on vortex-induced motions of a semi-submersible platform with four square columns, Part I: Effects of current incidence angle and hull appendages
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
An experimental study on Vortex-Induced Motion (VIM) of the semi-submersible platform concept with four square columns is presented. Model tests were carried out to check the influence of different headings and hull ...
Parametric analysis of a phenomenological model for vortex-induced motions of monocolumn platforms
(Associação Brasileira de Engenharia e Ciências Mecânicas - ABCM, 2011)
Phenomenological models are an important branch in VIV (Vortex-Induced Vibrations) and in VIM (Vortex-Induced Motions) studies to complement the results achieved via CFD (Computational Fluid Dynamics), as the latter tool ...
An Overview of Relevant Aspects on VIM of Spar and Monocolumn Platforms
(ASME-AMER SOC MECHANICAL ENGNew York, 2012)
Vortex-induced motions (VIM) of floating structures are very relevant for the design of mooring and riser systems. In the design phase, spar and monocolumn VIM behavior, as well as semisubmersible and tension leg platform ...
Experimental study on vortex-induced vibration of floating circular cylinders with low aspect Ratio
(ASMESan Francisco, 2014-06-08)
Experiments regarding vortex-induced vibration on floating circular cylinders with low aspect ratio were carried out in a recirculation water channel. The floating circular cylinders were elastic supported by a set of ...
Experimental Comparison of Two Degrees-of-Freedom Vortex-Induced Vibration on High and Low Aspect Ratio Cylinders with Small Mass Ratio
(ASMENEW YORK, 2012)
Vortex-induced motion (VIM) is a specific way for naming the vortex-induced vibration (VIV) acting on floating units. The VIM phenomenon can occur in monocolumn production, storage and offloading system (MPSO) and spar ...
