FLEXASSURE™ is a result of over 15 years experience in monitoring risers, using standard off-the-shelf products developed and deployed by 2H on numerous offshore developments.
The system uses state-of-the-art sensors to detect the following key parameters on-line, providing instant feedback at the vessel, as well as relaying the data to 2H’s office for more detailed analysis and identification of long-term trends:
Benefits
- Detects armor wire failure using a range of sensors to identify the signature response when an armor wire under tension breaks
- Detects the presence of gas build-up in the pull-tube: using a gas detection system in the I-tube
- Detects the build-up of corrosive gases in the riser annulus using a gas detector on the riser vent valve
- Vessel offset monitoring: via a GPS system
- Riser top tension: comparing vessel offsets and riser top angle, the riser top tension is recorded, and periods of excessive tension identified
- Riser VIV: using accelerometers and inclinometers on the riser to detect VIV signatures
