Abstract
A vortex induced vibration suppression system for use on a subsea riser system having either a stake or fairing component includes at least one fiber optic sensor mounted on the component. The fiber optic sensor associated with the riser includes at least one sensor for producing a sensor signal. The system may include a plurality of sensors and the plurality of signals produced thereby are combined at a multiplexer for generating a single, composite sensor signal. The signal may be monitored in real time or near real time for observing and monitoring the reaction of the subsea riser to conditions inducing vibration.
