"In order to disrupt the Soviet gas supply, its hard currency earnings from the West, and the internal Russian economy, the pipeline software that was to run the pumps, turbines, and valves was programmed to go haywire, after a decent interval, to reset pump speeds and valve settings to produce pressures far beyond those acceptable to pipeline joints and welds," Reed wrote. "The result was the most monumental non-nuclear explosion and fire ever seen from space."
All US (FERC) pipelines are required to multiple pressure relief systems. These are not systems that depend on the process control software. The operators do not have the ability to bypass these without physically being at the facility for a manual operation.
