At the Portland Pipeline

Since opening in the autumn of 1941 Portland Pipeline has delivered more than 4 billion barrels of crude oil to Canada. The 100 acre tank farm and marine terminal in So. Portland receives about 22 tankers a month and the tank farm has a capacity of about 3.2 million barrels of oil. The tank arm in Montreal has a capacity of approximately 1.5 million barrels. PMPL’s two pipelines, 18 inch and 24 inch in diameter, are monitored and controlled by a computerized supervisory control and data acquisition computer system (SCADA) operated from a control center located in So. Portland. SCADA provides operating intelligence and controls to the pipeline operator and enables the operator to remotely control pump intelligence and controls to the pipeline operator and enables the operator to remotely control pump units at the eight pump stations and to direct and follow the crude oil into and out of PMPL’s storage tanks. In 2002, deliveries to Montreal averaged 418,000 barrels per day from a total of 235 tankers.
