Alyeska announces pipeline maintenance schedule

JUNEAU, Alaska (AP) -- The operator of the trans-Alaska pipeline system has announced several planned shutdowns for maintenance.

Alyeska Pipeline Service Co. says the first shutdown is scheduled for Friday. It is set to last four hours to allow for valve maintenance along the 800-mile line.

The company, in a release, also announced maintenance shutdowns for June 8, June 30, July 8 and Aug. 9. The longest of these are expected to last 18 hours.

Alyeska says it conducts maintenance shutdowns each year to allow time to work on projects along the pipeline and at the Valdez Marine Terminal.

The company says the shutdowns typically coincide with the routine maintenance schedule for equipment and facilities by the North Slope oil companies.
