Pipeline integrity study improves inspection process
Alyeska engineers have devised a better way
to find hidden dents and other mechanical damage to the Trans
Alaska Pipeline System (TAPS).
They developed a technique to review data collected by an
ultrasonic in-line inspection tool, better known as a "pig,"
to efficiently discover and examine the extent of mechanical
damage to pipeline walls.

In the Field
Pump Station 1 connected to Prudhoe Bay Power
Grid
Alyeska reached a pipeline reconfiguration
milestone this spring when workers connected Pump Station 1
(PS 1) to Prudhoe Bay's central power grid.
PS 1 will use as much as 21 megawatts (MW)
of electricity during normal operation after electrification
is complete: enough power to serve 7,000 homes.

President's Message
David Wight, President and CEO
Preparing minority students for science and engineering careers
Alyeska understands the importance of having a diverse work
force and supports programs that increase minority
participation in engineering and science. Every summer we
select a group of engineering students to work for 12 weeks as
interns at Trans Alaska Pipeline System sites. These students
gain valuable professional and on-the-job experience.

years of her life away from Alaska, when she was studying at
the University of Hawaii. Anne has a business management
degree and worked for the State of Alaska, the Municipality of
Anchorage and First National Bank Alaska before joining
Alyeska as HR operations manager. She likes to camp and fish

Pipeline 101
Corrosion Control
Corrosion occurs naturally any time metal and electrolytes,
such as water, come into direct contact. External pipe
corrosion poses the biggest challenge along the Trans Alaska
Pipeline System's 380 miles of buried pipe. Alyeska's
corrosion monitoring and repair program limits pipeline
corrosion to insignificant levels. It uses standard industry
corrosion analysis techniques plus more rigorous computer
analysis programs that account corrosion depth and surface
extent.
