WFS Unveils Riser Monitoring System

New solutions unveiled Thursday by WFS Technologies aim to tackle the real-time monitoring of offshore risers both above and below surface, on fixed structures including jackets and braces.

The new Seatooth Assure Riser Monitor 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, the Scotland-based subsea technology company said.

Seatooth communicates through the water-air boundary removing the need for traditional dunkers.

WFS founder and CEO Brendan Hyland said the Seatooth Assure Riser Monitor 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,” he said.

Riser monitoring sensor data is used to validate riser fatigue analysis methods and recalibrate 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.
