Dynamic Compression of Rigid and Flexible Risers: Experimental and Numerical Results
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dynamic compression and buckling are critical issues in the viability analysis of rigid and flexible risers developed for offshore applications, especially concerning deep-water operations. Those ...
URANS Calculations for Smooth Circular Cylinder Flow in a Wide Range of Reynolds Numbers: Solution Verification and Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow around circular smooth fixed cylinder in a large range of Reynolds numbers is considered in this paper. In order to investigate this canonical case, we perform CFD calculations and ...
Mitigation of Vortex-Induced Motion (VIM) on a Monocolumn Platform: Forces and Movements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: 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 ...
Analysis Methodology for Vortex-Induced Motion (VIM) of a Monocolumn Platform Applying the Hilbert–Huang Transform Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: 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 ...
Experimental Comparative Study on Vortex-Induced Motion (VIM) of a Monocolumn Platform
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: 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 ...
An Overview of Relevant Aspects on VIM of Spar and Monocolumn Platforms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: 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 ...
Experimental Comparison of Two Degrees-of-Freedom Vortex-Induced Vibration on High and Low Aspect Ratio Cylinders with Small Mass Ratio
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: 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 ...
