Workers at the end point of the trans-Alaska pipeline are using saws to cut up large chunks of snow on top of oil storage tanks so they can shove the chunks off the tanks
This March 16, 2022, drone photo provided by Alyeska Pipeline Co. shows snow covering 62-foot tall and acre-wide oil tanks at the Valdez Marine Terminal in Valdez, Alaska. Workers at the endpoint of the trans-Alaska oil pipeline are using saws to cut up large blocks of hard-packed snow on top of the oil storage tanks so they can shove the chunks off the tanks, some of which have damaged infrastructure after more than 4 feet of snow fell in Valdez in a month.
The tanks are located at the Valdez Marine Terminal and Alyeska said it has periodically taken some of the 14 tanks out of service. There have been no disruptions to oil shipments, the company said.As many as 80 contractors wearing respirators to protect them from fumes are working in shifts around the clock to clear the snow off the tanks, Alyeska spokesperson Michelle Egan said. Additional resources are expected.
Each of the 14 tanks is 62 feet tall and spans 1 acre . It generally takes a crew of 10 or 11 people up to two weeks to clear snow from each tank. The tanks hold the oil until it is loaded onto tankers for shipment. Alyeska is owned by affiliates of North Slope producers ConocoPhillips, Exxon Mobil and Hilcorp. The pipeline moves about 500,000 barrels of crude a day through the 800-mile pipeline.Up to four tanks have been taken out of service at various points after the snow pileup sheared off valves installed along the upper edges of the tank roofs.
