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.
