Development of ANN Model for the Prediction of VIV Fatigue Damage of Top-tensioned Riser
MATEC Web of Conferences, 2018 Marine riser experiences vortex-induced vibration (VIV) caused by current, leading to fatigue damage if VIV is not considered in design of riser. Estimation of VIV fatigue damage is essential in designing feasible and operable riser.

Improved VIV Response Prediction Using Adaptive Parameters and Data Clustering
Journal of Marine Science and Engineering, 2020 Slender marine structures such as deep-water riser systems are continuously exposed to currents, leading to vortex-induced vibrations (VIV) of the structure. This may result in amplified drag loads and fast accumulation of fatigue damage.

Experimental study on vortex induced vibration of risers with fairing considering wake interference
International Journal of Naval Architecture and Ocean Engineering, 2017 Vortex Induced Vibration (VIV) is a typical flow-structure interference phenomenon which causes an unsteady flow pattern due to vortex shedding at or near the structure's natural frequency leading to resonant vibrations.
