WFS Technologies, a global provider of Subsea Internet of Things (SIOT®) devices, has unveiled solutions to tackle the real-time monitoring of offshore risers both above and below surface, on fixed structures including jackets and braces.

The new products allow for the measurement of 9-axis motion (vibration, orientation), local analytics and the reporting of real-time information through the water-air boundary with WFS’ patented Seatooth® technology; a first of its kind for the industry.

Seatooth communicates through the water-air boundary removing the need for traditional dunkers. The benefits of removing the use of dunkers include improved safety, reduced operating risk, real time information in the most extreme weather conditions.

Riser monitoring sensor data is used to validate riser fatigue analysis methods and re-calibrate existing predictive models. The WFS sensors are enabled with edge computing that can be used to validate the model in subsea conditions, and report data in real time. Edge computing enables the fatigue model to be uploaded to each sensor. Analysis is undertaken locally, with the relevant data logged on the sensor and any deviation from the model communicated wirelessly by exception.

“Seatooth Assure Riser Monitor is the most advanced riser monitoring solution on the market,” said Brendan Hyland, founder and CEO of WFS Technologies.

“Building on proven and qualified subsystems, it provides operators with real time, actionable information on riser condition in all operating environments. We believe this will lead to improved safety, reduced risk of environmental incidents and reduced costs.”
