Pipeline operators in oil, gas and city gas distribution walk thousands of kilometres of right of way to check that cathodic protection is doing its job. Much of that ground has no signal, and much of the data is still cleaned up after the fact by subject-matter experts in the office.
What goes wrong when data is cleaned later
- Readings transcribed by hand from the voltmeter
- Positions approximate, with no record of GPS accuracy
- Under-protected sections found weeks after the survey
- Uploads lost or duplicated on poor networks
What we built
For a pipeline-integrity services firm, we built an offline-first mobile collector for cathodic-protection surveys. Every reading lands in on-device storage first; a digital voltmeter connects over Bluetooth; each reading carries its GPS position and accuracy; and readings that breach the protection criterion are flagged on the spot. Sync runs in batches with acknowledgement and retry, and a CSV export matches the platform's import mapping.
Four survey types, one capture surface
As built
| Survey | What it finds |
|---|---|
| CIS | Protection levels along the line, on and off potentials |
| DCVG | Coating defects and their severity |
| ACVG | Coating defects from an applied AC signal |
| ACCA | Coating condition from signal current loss |
Note: Survey types supported by the collector.

Where to start
Start with one line and one survey type, run the collector alongside the current process for a season, and compare the time from survey to integrity decision.
