Alyeska Pipeline Service Company · Anchorage, AK United States

Named after the Aleut word for mainland, The Alyeska Pipeline Service Company operates the 800-mile-long, 48-inch-diameter pipeline that transports crude oil from Alaska's North Slope to the marine oil terminal of Valdez in Prince William Sound. Founded in 1970 to make the newly discovered finds in Prudhoe Bay commercially accessible, the company was assigned the task of designing, building, operating, and maintaining the Trans-Alaska Pipeline System (TAPS). The $8 billion pipeline was completed in 1977. The volume of oil flowing through the pipeline averages about 1 million barrels per day. TAPS is owned by a consortium of oil and gas firms, including BP (47%), ConocoPhillips (28%), and Exxon Mobil (20%). To read the full description, subscribe now.
