Application of Intelligent Monitoring System in Crude Oil Storage Tank Leakage Early Warning

The intelligent monitoring system realizes real-time monitoring of crude oil storage tank leakage through fiber optic strain sensors (accuracy ±0.1mm) and infrared spectral imaging technology (resolution 640×512). The system integrates AI algorithms (identification accuracy ≥98%) and can simultaneously detect tank deformation, oil film diffusion, and gas dissipation. The response time is ≤30 seconds, which is 90% more efficient than traditional manual inspection.

The early warning mechanism adopts a three-level linkage strategy: 1) Micro-leakage (<0.1m³/h) triggers audible and visual alarms and pushes notifications to the operation and maintenance terminal; 2) Medium-leakage (0.1-1m³/h) automatically closes associated valves and starts emergency pumps; 3) Large-leakage (>1m³/h) links the fire protection system and generates evacuation routes. The system uses BeiDou positioning (error ≤1m) to accurately locate the leak point and cooperates with the BIM model to realize three-dimensional visual emergency command.

Practical application shows that the system can reduce the discovery time of leakage accidents from an average of 4 hours to within 5 minutes, and reduce annual maintenance costs by 35%. After deployment in a coastal tank farm, it successfully provided early warning for 3 cases of corrosion perforation leakage, avoiding direct economic losses of over 20 million yuan, and meets the requirements of both API 650 and GB 50341 standards.
