Pipeline Quick Facts
The Trans Alaska Pipeline System was designed and constructed to move oil from the
North Slope of Alaska to the northern most icefree port in Valdez, Alaska.
Length: 800 miles.
Diameter: 48 inches.
Crosses three mountain ranges and over 800 rivers and streams.
Cost to build: $8 billion in 1977, largest privately funded construction project at that
time.
Construction began on March 27, 1975 and was completed on May 31, 1977.
First oil moved through the pipeline on June 20, 1977.
Over 15 billion barrels have moved through the Trans Alaska Pipeline System.
First tanker to carry crude oil from Valdez: ARCO Juneau, August 1, 1977.
Tankers loaded at Valdez: 19,625 through April 30, 2008.
Storage tanks in Valdez 18 with total storage capacity of 9.1 million barrels total.
The mission of Alyeska's Ship Escort Response Vessel System is to safely escort
tankers through Prince William Sound.
More than 70,000 people worked on the project at some point
31 people died
Delivers 20% us oil production
Permafrost & Vegetation
Oil runs through pipes at 82 degrees C. This would melt the permafrost which
would destroy the delicate environment. Melting permafrost would cause
subsistence which would cause the pipeline to sink and break
420 miles of pipeline are above the ground
4 miles are refrigerated below ground
For 376 miles of thawstable and nonpermafrost areas, the pipe is laid below the
ground
Vegetation in the Tundra can take 20 years to grow again once disturbed due to the
short growing season and harsh conditions. Quick growing species were introduced
once construction finished to stabilise the area
The pipeline has been designed with radiators to allow heat to escape into the air
rather than the ground
