Anchorage, AK – The Trans Alaska Pipeline System was restarted at 5:45 p.m. Monday, June 20, after workers completed a series of projects during a scheduled maintenance shutdown. The shutdown lasted nearly 36 hours. Key work activities included installing infrastructure at Pump Station 4 to prepare the station for Alyeska’s Strategic Reconfiguration project, replacement of two pig trap valves at Pump Station 4, and installation of a 48-inch mainline check valve at Pump Station 7. In addition, approximately 40 other work tasks were performed during the shutdown at other pump stations, remote valve sites, and at the Valdez Marine Terminal.

This was the first of two maintenance shutdowns scheduled this summer. The second shutdown is planned for July 23-24 and will also last approximately 36 hours.

Alyeska Pipeline conducts line-wide shutdowns nearly every year to allow maintenance crews time to work on projects simultaneously along the pipeline and at the terminal. These shutdowns coincide with the producers’ routine maintenance on equipment and facilities on the North Slope.

The shutdown work was completed safely with no injuries or spills on the pipeline.
