This delivery of BSE, our real-time safety evaluation system for boiler pressure parts, provides a field reference in the overseas power generation market.
BSE — Boiler Safety Evaluation
Remaining life of boiler pressure parts, calculated in real time
BSE (Boiler Safety Evaluation) is a 12-stage life assessment pipeline that combines physics-based models grounded in international standards with real-time OPC UA data to predict the remaining life of each asset. It is a field-proven product, delivered in 2024–2025 to an independent power project (PP12) in Saudi Arabia.
Capabilities
Core capabilities
Combines physics-based models grounded in international standards with real-time operating data to quantify pressure part damage.
Metal temperature calculated by inverse analysis based on Green's function, with stress analysis using the Lamé solution (thick-walled cylinder)
Combination of thermal and internal pressure stresses
Fatigue damage assessment using rainflow cycle counting (ASTM E1049) and Miner's rule (D = Σ(n/N))
Creep damage assessment using the Larson–Miller parameter (LMP) and Robinson's life-fraction rule
Remaining life from combined fatigue and creep damage: 25 years × (1 − Dtotal)
Real-time operating data integration via OPC UA, with data cleansing (outlier removal, interpolation, averaging)
Architecture
12-stage life assessment pipeline
From data acquisition and cleansing to temperature calculation, stress combination, damage assessment and remaining life calculation, physics-based models grounded in international standards and real-time OPC UA data work together in a single flow.

Why BSE
What sets BSE apart
01
Physics engine of our physics + AI stack
Preserves the conservatism of deterministic, ASME code-based assessment while refining results with real-time data.
02
In-house developed, independent of imported vendor systems
Supports data sovereignty and reduces dependence on foreign vendors.
03
On-premises, air-gapped deployment
Meets the security requirements of power generation companies.
Impact
Benefits
- Continuous visibility of remaining life for each asset, providing a sound basis for maintenance decisions
- Quantitative management of pressure part damage (fatigue and creep)
- Reliability demonstrated through deployment at an overseas independent power project
Return on investment (ROI) is estimated individually for each deployment.
