Other shortcomings
28 The system also had other shortcomings that could fairly easily have been remedied:
Monitoring screen
29 There was only one visual display screen for the data provided by the ATG system on a number of tanks which meant that the status of only one tank could be fully viewed at a time. On the night of the incident the display relating to
Tank 912 was at or near the back of a stack of four other tank display ‘windows’. Only one computer was provided, with no back up, to run the entire ATG system. The supervisors relied heavily on the ATG system to control tank filling so having no back up for this critical control process was inadvisable.
