The Alaska Pipeline

The Alaska pipeline The Alaska pipeline starts at the frozen edge of the Arctic Ocean

It stretches southward across the largest and northernmost state in
the United States, ending at a remote ice-free seaport village nearly
Line 800 miles from where it begins. It is massive in size and extremely
(5) complicated to operate.
The steel pipe crosses windswept plains and endless miles of
delicate tundra that tops the frozen ground. It weaves through
crooked canyons, climbs sheer mountains, plunges over rocky
crags, makes its way through thick forests, and passes over or
(10) under hundreds of rivers and streams. The pipe is 4 feet in diameter,
and up to 2 million barrels (or 84 million gallons) of crude oil can
be pumped through it daily.
Resting on H-shaped steel racks called "bents," long sections of
the pipeline follow a zigzag course high above the frozen earth.
(15) Other long sections drop out of sight beneath spongy or rocky
ground and return to the surface later on. The pattern of the
pipeline's up-and-down route is determined by the often harsh
demands of the arctic and subarctic climate, the tortuous lay of the
land, and the varied compositions of soil, rock, or permafrost
(20) (permanently frozen ground). A little more than half of the pipeline
is elevated above the ground. The remainder is buried anywhere
from 3 to 12 feet, depending largely upon the type of terrain and
the properties of the soil.
One of the largest in the world, the pipeline cost approximately
(25) $8 billion and is by far the biggest and most expensive construction
project ever undertaken by private industry. In fact, no single
business could raise that much money, so 8 major oil companies
formed a consortium in order to share the costs. Each company
controlled oil rights to particular shares of land in the oil fields and
(30) paid into the pipeline-construction fund according to the size of its
holdings. Today, despite enormous problems of climate, supply
shortages, equipment breakdowns, labor disagreements, treacherous
terrain, a certain amount of mismanagement, and even theft, the
Alaska pipeline has been completed and is operating.
