AI Technical Summary
Existing passive control devices have limited effectiveness in suppressing vortex-induced vibrations and their adaptability to complex and variable ocean current environments needs to be improved.
Design a vortex-induced vibration suppression device, including a fairing and a bearing. The outer surface of the fairing is a circumferentially closed arc-shaped curved surface, and it is equipped with multiple turbulence-inducing parts and a tail fin structure. Through the synergistic effect of the fairing, turbulence-inducing parts and tail fin, the width and scale of the vortex are reduced, thereby reducing the vortex-induced force.
It effectively suppresses vortex-induced vibration around the marine riser, extending the service life of the marine riser.
