Trans-Alaska Pipeline (1977)
The United States built a 1,287-kilometer pipeline across Alaska to move crude from Prudhoe Bay, then the largest oil field in North America. At peak, it carried about 2.1 million barrels per day, roughly 105 million tonnes a year, from the Arctic to the ice-free port of Valdez.
The pipeline transformed Alaska's economy and anchored U.S. domestic production for decades.
It remains the model for moving Arctic crude through hostile terrain, though the field has since declined.
Vostok Oil is comparable in scale and logistics difficulty, but Russia's route runs through the open Arctic Ocean rather than to a warm-water port.
