Alyeska completes 2nd scheduled shutdown
Alyeska Pipeline Service Co. has completed the summer’s second scheduled maintenance shutdown of the trans-Alaska oil pipeline.
The shutdown, which began July 31, ended Aug. 1 at about 1:35 p.m., the company said in an Aug. 2 statement.
Major work completed during the shutdown included replacement of a 36-inch valve at Pump Station 9 that is used for weekly pig passage; replacement of the gas supply lines to the Pump Station 3 and Pump Station 4 turbine generators; and replacement of the six-inch bypass piping on a check valve near Pump Station 1
Numerous other work tasks were completed at the pump stations and at the Valdez Marine Terminal.
Alyeska said it conducts line-wide shutdowns annually to allow maintenance crews time to work on projects simultaneously along the pipeline and at the Valdez Marine Terminal. Alyeska’s shutdowns typically coincide with producers’ routine maintenance on equipment and facilities on the North Slope, the company said.
