In 1977, the Trans-Alaska Pipeline System (TAPS) began transporting crude oil from Alaska's North Slope 1,288 km (800 miles) south to the Valdez Marine Terminal--the northernmost ice-free port in North America. Long considered to be one of the most difficult engineering feats, the pipeline crosses several major mountain ranges and rivers. TAPS transports approximately 20% of the crude oil produced in the US, averaging 1.10 million BPD in 1999. A comprehensive Corrosion Control Management Plan (CCMP) was introduced by Alyeska earlier this year to ensure that sound engineering practice is being used to determine the adequacy of cathodic protection (CP) on TAPS. Corrosion is a significant issue mainly on the 612 km (380 miles) of buried pipeline. The remaining 676 km (420 miles) of pipeline are located aboveground. The paper describes the maintenance of the cathodic protection system.
