data. The pipeline is available to the operator end-to-end at the computer
workstation for any purpose his operation or maintenance may require.
Temperature, pressure, slope and defect information can be displayed on
the screen with the data, or graphically displayed for the entire line. Notes can
be added to a file that will always follow the pipeline location. This feature
allows the operator to view prior history notes with a simple key stroke. Notes
might contain information on origin of defect, repair made, defect growth,
etc.
