Effects of Varying Tension and Stiffness on Dynamic Characteristics and VIV of Slender Riser
A time-domain approach for predicting dynamic characteristics and vortex-induced vibration (VIV) response of deepwater risers is proposed by coupling finite element simulation and a hydrodynamic model. Numerical results indicate that axially varying structural parameters can efficiently change the m...
