Flexlife, a specialist provider of flexible pipe technologies and engineering services, has successfully completed a field trial in the first application of its FlexGuard riser monitoring system at Chevron’s Captain field in the UK North Sea.

FlexGuard is an ultrasonic device designed to provide continuous real-time data on the condition of flexible risers for remote monitoring, with the data conveyed by acoustic telemetry to a surface vessel.

Luke Wilkinson, project manager and principal engineer at Flexlife said:

"We were invited by Chevron to trial the FlexGuard technology on the 10" flexible riser at the Captain FPSO (floating production, storage and offloading vessel), A bespoke FlexGuard clamp had to be designed and manufactured to fit the riser. This was was installed on the 10” riser 40 metres below the water line during the initial phase of the project in June 2012."

"Data produced showed that the annulus was not flooded where the Flexguard module was installed and therefore had not been exposed to oxygenated seawater which could cause corrosion of the riser’s structural steel wires."

"The trial delivered proof of concept of the product as an early detection system for potential riser integrity issues. FlexGuard is now at a market ready stage and suitable for commercial deployment."

FlexGuard incorporates Flexlife’s patented non-invasive UT scanning technology in the form of a lightweight collar permanently fitted to flexible risers.

The subsea riser monitoring tool provides the operator with instant, continuous monitoring of any riser. This information can be acquired remotely from any location in the world – ensuring a failsafe early warning system providing major cost and safety benefits. The system can be installed either during installation or by retrofit to risers already in operation in the field.

FlexGuard forms part of Flexlife's unique suite of flexible pipe products and services, which also includes annulus testing, FlexGel and Armadillo.
