VORTEX-INDUCED VIBRATION SUPPRESSION DEVICE AND MATING COLLAR SYSTEM

摘要

A system including a vortex-induced vibration (VIV) suppression device dimensioned to suppress a vortex-induced vibration of a support structure, the VIV suppression device having a base portion that encircles at least a portion of the support structure and a support member formed along the base portion. The system further including a collar having a body portion defining an annular channel and a flange portion extending outwardly from the annular channel, the flange portion dimensioned to form a receiving channel around the support structure for receiving the support member. The support member is received within the receiving channel to secure the VIV suppression device to the support structure and the VIV suppression device is capable of rotating around the support structure along the receiving channel.
