Abstract

Vortex-induced vibration (VIV) is a crucial contributor to the fatigue damage of slender marine structures such as offshore risers and wellhead and must be accounted for during design. Currently, engineering methods that predict VIV for such structures commonly rely on VIV databases for cylinders but fail to account for surface defects resulting from factors such as corrosion. Therefore, resulting predictions may overlook the magnification effect of vibration caused by surface defects, leading to an underestimation of structural vibration amplitude and fatigue damage. To address this issue, a model experiment was conducted to analyze the flow-induced vibration response characteristics of defective cylinders with varying defect depths and incoming flow angles. The results showed that the modal properties of the defective cylinder were complex, exhibiting several modes such as galloping, VIV, and resonance modes. Surface defects can induce galloping vibration mode and significantly increase the cylinder's vibration amplitude, up to a maximum of 7.5 times. Furthermore, at an attack angle of 0°, the defective cylinder demonstrated the highest amplitude and largest resonance range, while at an attack angle approaching α=90°, the amplitude of the defective cylinder sharply decreased and was lower than that of the intact cylinder. Surface defects can also suppress vortex vibration modes, thereby suppressing galloping. The cylinder had the maximum galloping amplitude at a defect depth of 7.5%. In addition, surface defects can also lead to an increase in the range of resonance flow velocity.
