Trans-Alaska Pipeline System (TAPS)

​​TAPS

The Trans-Alaska Pipeline System (TAPS) was the world’s largest privately funded construction project when it was built, at a cost of $8 billion. The system includes the 800-mile-long pipeline, which runs from Prudhoe Bay to Valdez, and the Valdez Marine Terminal, where oil is loaded onto tankers for shipment to market.

The pipeline has become an engineering icon and has set a standard for design which endures to this day. Its distinctive zig-zags allow the pipe to flex in the event of an earthquake. More than half the pipeline runs above ground on 78,000 vertical support members. Construction of the pipeline project began in April 1974 and finished in June 1977. A total of 70,000 people were involved in building the line.

ConocoPhillips is one of three companies that owns TAPS. The pipeline is operated by Alyeska Pipeline Service Company (Alyeska) on behalf of its owners. Alyeska also operates the Ship Escort/Response Vessel System (SERVS), helping to safely transport tankers through the Prince William Sound and providing extensive spill response preparedness.
