RiserMonitoring
Rigid Risers
OngoingR&D
The movement of the rigid risers requires consistent integrity monitoring to guarantee production and reduce operational risks.
Monitoring in rigid risers offers excellent thermal insulation and high resistance to CO2 contact. This system, installed before the pull-in, eliminates the need for intervention during production, optimizing the process and reducing operational risks.

Strain
TopStrain
The Top Strain Monitoring System provided by ouronova uses fiber optic sensors to measure strain and stress at the top of rigid risers, axial tension and bend moment.
- Passive system (no electric current)
- High resistance to corrosive environments
- Lower signal degradation over time
- High precision

Inclination
TopInclination
ouronova´s Top Inclination Monitoring System is designed to measure roll and pitch of rigid risers to assess the wear of the polymeric materials. The system, installed at the top of rigid risers, does not require alignment with the catenary to be installed before pull-in without diver intervention.
- No misalignment tool is required
- Retrievable System
- Retrofit System
