Abstract

Riser system is an indispensable structure connecting offshore platform and submarine wellhead, which is very common in offshore engineering. When the fluid flows through the riser system, the vortex falls off on both sides of the riser and stimulates the riser vibration, resulting in the fatigue damage of the riser. The vortex-induced vibration under oscillating flow is analyzed in this paper. The results show that the vortex-induced vibration of cylindrical structures in oscillating flow is more regular when the reduced velocity is low. The oscillating flow causes multi-mode vibration of the cylindrical structure, and the locking interval increases with the increase of KC number. The shed vortices will pass through the cylinder again after changing the flow direction, changing the fluid force on the cylinder structure.
