Alyeska Pipeline Service Company annually conducts several planned pipeline shutdowns which last from 12 to 18 hours. These line-wide shutdowns provide maintenance crews with the time and opportunity to work on coordinated projects along the pipeline and at the Valdez Marine Terminal while the pipeline is not in its regular operating state.

Alyeska employees and contractor crews will conduct three planned maintenance shutdowns of the Trans Alaska Pipeline System (TAPS), set to occur between June 15 and July 6.

Employees from Alyeska, the pipeline operator, and TAPS contractors will complete projects at various locations along the 800-mile pipeline, from Pump Station 1 in Prudhoe Bay to the Valdez Marine Terminal, during scheduled shutdowns. Crews will accomplish the work during three 12-hour shutdowns and one 18-hour shutdown. Planned work includes:

 

  • Enhancing Safety Integrity Pressure Protection System (SIPPS)
     
  • Preparing for inline inspection of the pipeline that will begin this fall
     
  • Replacing 6-inch bypass valves and spool of a mainline check valve
     
  • Conducting annual inspection and maintenance of Pump Station 9 power substation

 

“Planned major maintenance plays a critical role in sustaining TAPS for decades to come,” said Tom Barrett, Alyeska President. “Alyeska maintains the pipeline as our commitment to the integrity of the system and people of Alaska.”

A successful shutdown involves multiple organizations that work on TAPS, as well as months of preparation and coordination between field locations and Alyeska’s Operations Control Center.
