Trans-Alaska Pipeline System; a large-diameter pipeline built from the oil rich North Slope of Alaska to the warm-water port of Valdez on the state's south shore. The 48-inch, 800-mile pipeline was completed in the summer of 1977. Its designed throughput is 1.2 million barrels a day. The Valdez crude oil terminal covers 1,000 acres and is one of the world's largest. The terminal has four loading berths for tankers up to 200,000 deadweight tons displacement.
