They began building the pipeline in 1974 and
finished building it in 1977.
In twenty years more than eleven billion
barrels of oil have gone through the pipeline.
The Alyeska Pipeline Service Company operates
the pipeline. This company is made up of seven oil companies. They
are: BP, ARCO, Exxon, Mobil, Amerada Hess, Phillips, and
Unocal.
88,000 barrels of oil go through the pipeline
in one hour.
There are 42 gallons of oil in one barrel.
The oil in the pipeline takes 4 and a half
days to travel the 800 miles.
When the whole pipeline is full of oil it
holds 9.04 million barrels of oil.
There are people in little buildings along the
pipeline that help to make sure that the oil continues to flow and
that work to prevent spills from happening. There are 10 of these
pumpstations along the 800 miles of the pipeline.
It cost 8 billion dollars to build the
pipeline.
Every year it costs 210 millions dollars to
run the pipeline.
Back in the 1800's oil was stored in barrels.
They put the barrels in a wagon to take it from one place to
another.

This is a picture of an early pig. A
pig is a device that is put into the pipeline to clean
wax off the inside. It also can tell if the pipe is
getting rusty. They are launched at a station and then
taken out at another.
