Enbridge Pipeline System Line 55 (Flanagan to Cushing). As of 2013 there were expansion plans for the pipeline system which would, if permitted and fully built, provide the capacity to transport an amount of dilbit from the Athabasca oil sands into the United States and the Gulf Coast equal to that of the Keystone Pipeline. In 1991, Enbridge's Line 3 pipeline spilled 1.7 million gallons of oil in Grand Rapids, MN. This was the largest inland spill of oil ever in U.S. history. Deliberations over construction of a new Line 3 pipeline have drawn resistance from climate justice organizers and Native communities in
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
