In March of 2022, snow accumulated on Alyeska Pipeline Service Company’s crude storage tanks at the Valdez Marine Terminal and damaged several of the tank pressure vacuum pallets (or vents). The vent damage caused a leak of crude oil vapor from inside the tanks. This report by Taku Engineering summarizes their independent investigation of the damage, the associated vapor release, Alyeska’s response, and the proposed repair methods.
