Web-based Pig Tracking
Web-based Pig Tracking
An Above Ground Marker (AGM) is a sensor device used in pipeline inspection to detect and track pigs as they move through the pipeline. AGMs detect magnetic, acoustic, or RF signals emitted by the pig, recording the time and GPS location of its passage. This data is transmitted in real-time to central monitoring systems and stored locally for backup. AGMs are crucial for accurate pig tracking, ensuring pipeline inspection integrity, and identifying anomalies. They are typically installed at key locations like bends and valve stations, and can be powered by batteries, external sources, or solar panels.
An Above Ground Marker (AGM) detects the magnetic field generated by a pigs
magnets, Signals form an EM Transmitter, or the acoustic signal produced as the pig moves through the pipeline. This detection is achieved through sensors embedded in the AGM that can pick up specific magnetic, acoustic, or radio frequency (RF) signals.
Once a signal is detected, the AGM records the exact time and location of the pig’s passage. This data is then transmitted to a central monitoring system for real-time tracking and analysis. AGMs help pipeline operators maintain accurate records of pig movements, ensuring thorough inspection and maintenance of the pipeline.
AGMs are crucial in inline pigging because they provide precise tracking of the pig’s position, which is essential for maintaining the integrity of the pipeline inspection process. By accurately recording when and where a pig passes, AGMs enable operators to identify the exact locations of any detected issues or anomalies within the pipeline. This precise tracking helps ensure that all potential problems are detected in time and necessary maintenance and repair activities are planned. It enhances the overall safety and reliability of the pipeline infrastructure.
AGMs are strategically placed along the pipeline route at key locations such as bends, valve stations, and other critical points, where the pig’s movement might change direction. These strategic placements allow accurate detection and tracking of the pig throughout its journey, which is vital for effective pipeline inspection and maintenance.
AGM locations are determined based on several factors, including the geometry of the pipeline, specific inspection requirements, and accessibility. Pipeline bends, valve stations, and other critical points are often chosen to ensure comprehensive coverage. Additionally, operators consider the need to monitor areas where pipeline conditions might change, such as transitions in diameter or material. The goal is to strategically place AGMs to provide accurate and consistent tracking of the pig’s journey through the entire pipeline, ensuring that all potential issues are detected and recorded for further analysis and maintenance planning.
