Subsea Riser Maintenance Under Live Offshore Conditions
Subsea riser maintenance ensures the structural integrity and continued operation of critical offshore infrastructure connecting subsea wells to surface facilities. Fairtex delivers full-scope maintenance programs covering inspection, repair, and life-extension strategies for steel catenary risers (SCR), flexible risers, and hybrid systems.
Our teams operate in live offshore environments, coordinating with platform operations to execute inspection and intervention work without disrupting production. Maintenance scopes are aligned to API RP 2A, DNV-ST-N001, and ISO 13628 standards.
When to deploy riser maintenance: detected corrosion, fatigue cracking, coating degradation, marine growth accumulation, or scheduled integrity reassessment.
What this service covers
Inspection & Integrity Assessment
ROV-based visual inspection, ultrasonic thickness measurement, and fatigue hotspot analysis to detect degradation and assess remaining life.
Repair & Intervention
Clamp installation, coating repair, anode replacement, and localized reinforcement for damaged riser sections.
Corrosion Control
Deployment of cathodic protection systems and advanced coatings to mitigate corrosion in harsh subsea environments.
Key Takeaways
- Maintains riser integrity without shutdown
- Extends asset life and reduces replacement cost
- Fully compliant with offshore integrity standards
