Why can’t I use odometry for ILI runcoms?
(15-minute read) Odometry is understood to be useful for sorting inspection features, but it is useless for comparing them. There is too much disagreement. This article presents an alternative to the common “wheel slip” explanation. It describes odometry errors as an unavoidable consequence of bias introduced during navigation by dead reckoning.

Vocabulary for pipeline inspection matching (runcoms)
(5 Min Read – Industry) I am a data analyst. I have not seen a set of terminology that is from this perspective. These are the terms I use. Help me improve this? What is confusing?

Integrated Cleaning and Inspecting Pig (ICIP): Part 2 – Proximity Sensors (2 of 2)
*(20 Min Read – Technical)* This write-up demonstrates that inexpensive inductive proximity sensors can be used to construct inexpensive inspection tools. Commercial proximity sensors have a proven track record of operating in harsh environmental conditions. They have high shock and vibration resistance. They are chemical resistant and resistant to short circuits. The sensors we used…

Integrated Cleaning and Inspecting Pig (ICIP): Part 1 – Mechanical and Electronics (1 of 2)
*(10 Min Read)* This project aims to build an inexpensive screening pig. The use case is that this screening tool will be run frequently, and a composite understanding of the pipe wall will emerge by combining multiple assessments. To that end, the pig should be easy to operate and repair. A field hand should be…
