Predicting Pipeline Strain at geohazard Sites
Track and forecast bending strain in buried pipelines using historical inertial measurement unit (IMU) inspection data.
C-FER develops custom models that help operators understand how deformations evolve over time at geohazard-prone locations.
How It Works
Analyzes repeat IMU inspections
Applies weighted linear regression to prioritize recent data
Offers three regression methods:
- Age-weighted using all inspections
- Last two inspections
- Last three inspections
Users can input strain measurements from different time points and receive a predicted strain demand distribution for a future date—supporting proactive pipeline integrity management.
