Control Systems International Upgrades Alyeska Pipeline Company with UCOS® SCADA

November 162004
Alyeska Pipeline Service Company has broken away from the traditional pipeline SCADA systems and turned to a newer, more efficient technology called UCOS Pipeline SCADA. Alyeska is installing UCOS as the primary SCADA Master Station and Data Historian for the trans-Alaskan Pipeline.

The Alyeska Pipeline Services Company new UCOS SCADA system was supplied by Control Systems International (CSI), which also provided the implementation engineering for the projects.

UCOS (User Configurable Open Systems) applies object-oriented programming and user interface techniques, executes on standard, off-the-shelf hardware, and can be integrated with existing field equipment that often requires no rewiring.

Alyeska Pipeline Services Company

The trans-Alaskan Pipeline is more than 800 miles long and cost 8 billion dollars to build from 1969 to 1977, employing more than 70,000 people. (Actual construction took place from 1974 to 1977.) There are more than 42,000 double joint welds and 66,000 field girth welds. The pipeline is designed to withstand earthquakes using a unique support system that can allow the pipeline to move several feet horizontally without jeopardizing the integrity of the pipeline.

The pipeline is monitored and controlled from a master station at the Valdez Marine Terminal in Prince William Sound, the farthest northern non-freezing port in America. The pipeline climbs and descends three mountain ranges before delivering 17% of our nation’s domestic oil production from Alaska’s North Slope at Prudhoe Bay.

When the Alyeska project is completed, UCOS will provide instantaneous monitoring and control of all significant aspects of operations, including monitoring the pipeline’s leak detection system. Operators using real-time dynamic graphic displays monitor the system 24-hours a day and control oil movement through the pipeline and tanker loading.

UCOS will monitor and control 3,047 input points and 352 control points on the pipeline and 1,074 input points and 461 control points at the marine terminal. It scans 14 data acquisition units on the pipeline (each pump station, the North Pole metering facility and the Petro Star refinery), 24 units at the marine terminal, and 14 metering units. UCOS manages all data acquisition and control; alarm and data processing; display; and historical archiving and reporting. UCOS also interfaces with hydraulic modeling, leak detection, and seismic evaluation systems. By design, UCOS can monitor, control and interface to unlimited input and control points.
