Subsea Risers & Flowlines

This application offers advanced features for the digital integrity management of subsea risers, including real-time monitoring, inspection, digital inventory, and failure analysis management. The platform provides precise control of each pipe section along its full length through a cutting-edge pipe discretization feature. By integrating data from mechanical loads, materials and manufacturing details, inspection results and operational conditions, KAIROS generates specific operational envelopes for each set of variables.

This approach enhances a comprehensive digital integrity management for subsea risers, reducing inspection and repair costs, supporting safer and more reliable subsea operations.

As a powerful digital twin, it enables continuous section-by-section monitoring of critical failure modes, such as fatigue and stress corrosion cracking.

Inspections

Integrity assessments for each discretized section along the risers
Comparison of integrity data between different risers or specific sections (e.g., compare all top riser integrity data across the entire floating unit)
Failure patterns identification and critical areas identification

Inventory

Specific numerical models for each discretized section with details of mechanical and material properties
Inspection data associated with individual sections along the riser

Service Life

Virtual sensors to calculate and monitor mechanical loads applied to the risers
Operational envelopes for specific failure modes, such as Stress Corrosion Cracking (SCC)
Real-time fatigue analysis based on virtual sensor data

Fatigue Analysis

Historical data from loads, inspection and repairs, creating a robust foundation for failure analysis and lifecycle assessment
Root cause analysis tools to identify critical factors and optimize intervention planning
