Alaska pipeline running at about 5 percent


The shutdown of the 800-mile trans-Alaska oil pipeline continued for a second day Sunday as engineers and regulators worked on how to safely get oil flowing again in the dead of winter.

Alyeska Pipeline Service Co. cut the flow of oil to the main pipeline Saturday morning after workers discovered a leak on a secondary line.

… The effort is complicated by the cold. With the pipeline suddenly shut down, the oil already in it is cooling. Alyeska and government regulators are concerned about ice forming in the pipeline, which could cause additional problems when the oil begins flowing again.

…About 200 Alyeska employees and contractors are working on the problem, Egan said.
