This is the engineering summary of an open reference architecture. The paper, its object model as JSON and the model register are free to reuse under CC BY 4.0: https://codeatoms.ai/dc-interference-gas-pipelines-pakistan/ . The operator is described by class, never by name.

A gas pipeline operator in Pakistan has two buried lines within a kilometre of a high voltage direct current electrode station. When the HVDC link runs in monopolar mode, up to 1.3 kA returns through the ground, and some of it rides the operator's steel. The question the operator cannot answer today: along which sections does that current push pipe to soil potential past the cathodic protection criterion of minus 0.85 V against a copper sulfate electrode, and what mitigation, with what bill of quantities, restores it?

The records that should answer it are scanned survey sheets, coating reports, layouts and soil investigations with no provenance on any value, and the tender quotes a single backfill resistivity for ground the same records…
