Figure 1.

Overall workflow of the digital twin-based monitoring and maintenance system. Data from pipeline sensors are incorporated into the digital twin via the EnKF, and the updated states are analyzed by a machine learning module. Anomalies trigger maintenance actions, and the entire process adapts over time through continual retraining and model refinement.

Experiment 1 (Baseline Condition): Average residual magnitude remains low and stable, indicating accurate alignment between sensor data and model forecasts.

Experiment 3 (Combined Leak and Blockage): Timeline showing the onset and detection of two simultaneous anomalies. Dashed lines mark the true start of each anomaly, and dots indicate when the system raised alarms.
