LIVINGSTON, UKWFS Technologies has introduced products for real-time monitoring of offshore risers above and below the sea surface, on fixed structures including jackets and braces.

These allow for measurement of nine-axis motion (vibration, orientation), local analytics and reporting of real-time information using WFS’ Seatooth technology.

Seatooth communicates through the water-air boundary, removing the need for traditional dunkers. The benefits are said to include improved safety, reduced operating risk, and availability of real-time information even in extreme weather.

The system uses riser monitoring sensor data to validate riser fatigue analysis methods and re-calibrate existing predictive models.

The WFS sensors make use of edge computing to validate the model in subsea conditions, and report data in real time.

Edge computing allows the fatigue model to be uploaded to each sensor. WFS performs analysis locally, with the relevant data logged on the sensor and any deviation from the model communicated wirelessly.
