Enbridge Pipeline System directly linked to the pipeline. Another point in Lockport, Illinois connects two pipelines to Patoka, Illinois, plus a longer link to Cushing, Oklahoma. A relatively short link from Stockbridge, Michigan connects to two refineries in the Toledo, Ohio area.

Pipeline transport operational commands (open/close valves, turn on/off compressors or pumps, change setpoints, etc.) through the SCADA system to the field. To optimize and secure the operation of these assets, some pipeline companies are using what is called "Advanced Pipeline Applications", which are software tools installed on top of the SCADA system, that provide extended functionality to perform leak detection, leak location, batch tracking (liquid lines), pig tracking, composition tracking, predictive modeling, look ahead modeling, and operator training. Pipeline networks are composed of several pieces of equipment that operate together to move products from location to location. The main elements of a
