Alyeska Pipeline PUMP Stations

No.11 - 1984


Throughout much of the life of the pipeline, crude oil was moved down the line by a series of ten operating pump stations. An additional facility provided oil control capability and could have become a pump station if expansion by the system had been required. A twelfth station site was also available. Today only six of the original ten pump stations are being used to move oil through the line.(Production of oil on the North Slope has been declining because of the age of the oil fields, thereby reducing the amount of throughput of oil in the line, and thus requiring fewer pump stations.)

The heart of each station is the main pump building that houses gas-turbine-driven mainline pumps. Most stations have three pumps, each of which can move 22,000 gallons of oil each minute, or up to 754,000 barrels a day (one barrel equals 42 gallons).
