Targeted Riser Repairs for FPSO Systems
Riser systems on floating production units operate in high-stress environments where motion fatigue, corrosion, and contact damage can reduce integrity. SubseaPartner performs precision repairs on risers and support hardware in place, restoring operability without removal.
Our riser repair scopes include:
- Installation of engineered clamps over localized damage
- Reinforcement or realignment of riser support brackets and guides
- Splash zone clamp replacement and fastener renewal
- Bend stiffener inspection and restoration work
- Diverless Bend Stiffener Connector (DBSC) inspection & repair
All riser repair services are:
- Executed by ROV intervention and/or diving intervention
- Planned with inhouse engineering and specialist competence
- Documented with photographic and written verification
- Compatible with class follow-up or conditional certification
We support repairs as part of:
- Life extension programs
- SPS-driven findings
- Contingency repairs of compromised risers
SubseaPartner ensures all riser repair activities are performed safely, with focus on reinstating operational readiness and deferring major replacement costs.
Operational Scenario
Real Results: Bend Stiffener Repair Restores Riser Integrity.
Challenge
During an inspection campaign on the Balder FPSO, a bend stiffener on one of the turret-connected risers had become detached and had slid down the riser to the hog bend at -120msw.
Solution
SubseaPartner mobilized a certified dive team and together with the clients ROV vessel recovered the bend stiffener and reattached it to the DBSC. All work was executed on-station, without removing the riser or disrupting production.
Outcome
The stiffener repair successfully reinstated safe load distribution at the riser interface. The intervention allowed the riser to remain in full service, supported compliance with class requirements, and avoided early replacement.
