Vortex-induced vibration of catenary riser: reduced-order modeling and lock-in analysis using wake oscillator

, 2009
A new reduced-order model capable of analyzing the vortex-induced vibration of catenary riser in the ocean current has been developed. This semi analytical-numerical approach is versatile and allows for a significant reduction in computational effort for

Numerical Simulation of Vortex-induced Vibrations and Fatigue Life Factor Analysis of Marine Riser

Shiyou jixie, 2016
As it is difficult to implement 3D numerical simulation of VIV of marine risers due to its high cost and low calculating efficient,an equivalent 2D model based on spring-mass model is proposed to solve the vibration parameters (amplitude and frequency ...

The Effect of Shifting Natural Frequency on the Reduction of Vortex-Induced Vibrations of Marine Risers

International Journal of Coastal and Offshore Engineering, 2017
Many procedures suggest for reduction of responses of riser to Vortex Induced Vibrations (VIV). Natural frequencies of marine risers is an important parameter that can affect the responses of riser to VIV.
