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 ...
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 ...
Conceptual Design of Monocolumn Production and Storage With Dry Tree Capability
(ASME-AMER SOC MECHANICAL ENG, 2010)
A new concept and a preliminary study for a monocolumn floating unit are introduced, aimed at exploring and producing oil in ultradeep waters. This platform, which combines two relevant features-great oil storage capacity ...
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 ...
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 ...
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 ...
Semi-submersible hub platform with and internal dock model testing
(ASMESan Francisco, 2014-06-08)
The recent discoveries and development of the Pre-salt reservoir in Brazilian coast require a new logistical model for crew transportation and transhipment to the drilling and oil rigs due to the large distance from coast, ...
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 ...
