You mean with regard to global warming, or just normal summer thaw? The 48-inch diameter steel pipeline runs 800 miles and crosses three mountain ranges and over 800 rivers or streams. Typical pipeline construction at the time involved burying most pipelines, but because of the temperature, the oil had to be heated for it to flow which necessitated that about 400 miles of the pipeline be elevated above ground to keep the permafrost from melting. Areas where the pipeline had to go over permafrost had to have special supports so the pipeline would not move when the ground thawed. So, I don't think your concerns are warranted in that regard, backstop.
As to other vulnerabilities--on October 4, 2001, a surveillance helicopter for the Trans-Alaska Pipeline spotted a massive oil spill 80 miles north of Fairbanks. As it turned out, a drunken local resident had pierced the pipeline with a bullet from a .338 caliber rifle. The single shot resulted in the release of more than 285,000 gallons of crude oil across two acres of tundra forest. It also essentially shut down the pipeline for more than three days. While the economic and social disruption from a massive terrorist strike on a pipeline would likely be enormous, the Alaska incident illustrates how even "minor" attacks on the U.S. pipeline system can have widespread downstream implications.
