The Subsea vibration monitor is non-intrusive. It takes use of 3-axis accelerometer to monitor movements at subsea structures and pipes. It can monitor in both high and low frequency areas, making it possible to minimize risk of fatigue failure of pipes and other structural components. It can be supplied for permanent installations or for temporary inspections as a battery empowered solution. Typical sources of vibration include vortex induced vibration (VIV) and flow induced vibration (FIV). This instrument has become a valuable tool to monitor the state of the subsea pipework and structures. In several cases the application has enabled the operator to safely increase production as the measured level of vibration has been less than conservative models predict.
