Buried pipelines are critical infrastructures that transport water, petroleum, gas, and other substances. However, they are susceptible to damage from third-party interference (TPI) and other threats, which can lead to environmental contamination, explosions, fires, and sinkholes. Detecting such threats in advance has been a significant challenge for pipeline management entities.
The Korea Research Institute of Standards and Science (KRISS) has developed a groundbreaking early detection system designed to prevent buried pipeline failures. This system represents a significant advancement in the field of pipeline safety and monitoring.
The system operates by utilizing a pair of sensors placed several hundred meters apart along the pipeline. These sensors monitor the impact signals occurring between them, allowing for real-time detection of potential threats. The technology is akin to seismological centers that detect earthquakes by analyzing the arrival time of seismic waves.
Key Features:
- Real-time Monitoring: Capable of identifying activities that could potentially damage the pipelines before they occur.
- Elastic Wave Analysis: Uses precise measurement and analytical models of the elastic wave propagated upon impact.
- High Accuracy: During testing, the system detected impacts over roughly 20 kN with an accuracy rate of more than 95%.
Applications
The early detection system by KRISS is suitable for various types of pipelines, including those for water, oil, gas, and heat supply. Its ability to provide early warnings can significantly reduce the risk of pipeline damage and the associated environmental and safety hazards.
The KRISS team’s early detection system is a testament to the innovative strides being made in the field of infrastructure protection. It offers a proactive approach to safeguarding buried pipelines, ensuring the uninterrupted flow of essential resources.
