This system was proposed as part of a new chlorine pipeline project, accepted in November, 1998. The system functional specifications were developed, 5 site industrial control panels and enclosures were fabricated, and installation began mid February, 1999. The new pipeline was in operation for the first time in late April, 1999, with all 5 automation sites actively controlling the pipeline.
This system included an EDM designed product, our Trip-Wire© subsystem. Third Party damage is one of the leading causes of incidents for chemical, hazardous liquid, and gas pipelines. EDM Services has developed an intrusion detection system, which utilizes fiber optic technology and sophisticated communications equipment to detect intrusions before a third party damages a pipeline or other buried facility. In addition, the system can locate the potential intrusion within approximately one meter. When this equipment and software are incorporated into an integrated control system, the operator can be notified in real time of a possible intrusion situation. Personnel can then be dispatched to the exact location, preventing leak incidents.
This system included:
- High Availability/Redundant Host Servers
- Wonderware Human/Machine Interface (HMI)
- Redundant Allen-Bradley Programmable Logic Controllers (PLCs)
- EFA Leak Detection with redundant application servers, fully integrated with the HMI application
- Redundant Fiber optic network, including data and voice to each site to facilitate installation and trouble shooting
- Fiber optic EDM Trip Wire© subsystem
