Overview
CorrData calculates risk scores using a multi-factor model that considers:
- Cathodic protection effectiveness
- Coating condition
- Environmental factors
- Operational parameters
- Historical performance
Risk Score Scale
| Score | Level | Description |
|---|
| 0-25 | Low | Well-protected, no immediate concerns |
| 26-50 | Medium | Monitor closely, schedule routine maintenance |
| 51-75 | High | Requires attention, prioritize inspection |
| 76-100 | Critical | Immediate action required |
Risk Factors
Cathodic Protection (40%)
- Pipe-to-soil potential measurements
- Rectifier output adequacy
- Anode bed condition
- Current distribution
Coating Condition (25%)
- Coating type and age
- Holiday detection results
- Disbondment surveys
- Repair history
Environmental (20%)
- Soil resistivity
- Soil pH and moisture
- Proximity to interference sources
- Flooding potential
Operational (15%)
- Product type
- Operating pressure
- Age of pipeline
- Consequence of failure
Risk Trending
CorrData tracks risk scores over time to identify:
- Improving or degrading conditions
- Seasonal patterns
- Impact of remediation activities
- Long-term trends
Risk-Based Prioritization
Use risk scores to prioritize:
- Inspections - Focus on high-risk segments first
- Maintenance - Allocate resources where needed most
- Capital Projects - Justify replacement decisions
- Compliance - Demonstrate due diligence
Customization
Operators can customize:
- Factor weights based on their system
- Threshold values for risk levels
- Inclusion/exclusion of specific factors
- Alert triggers
Risk scores are decision-support tools, not definitive safety assessments. Always apply engineering judgment.
