Hi-viz poles to allow the chopper to follow the pipeline route easily.

They're not just markers, I'm sure they can actually let off gas.

They are simple makers for the helicopter that checks the pipeline to
follow with its airborne leak checker. One of the high pressure
pipelines runs close to me. They also mark the no dig zone at the
roadside (permission required from the pipeline owner Ineos or Shell).

That seems unfair; after a boring day mashing up roadside culverts and
the occasional fibre duct, a high pressure gas pipeline would be quite
an exciting find for JCB operator.



Somebody 'found' the underground fuel line when it ran through the
grounds of a large estate, and they dug down, tapped into it and
nicked loads of diesel.

Yeah, the pipeline company never bothers to measure how much product
enters and leaves the pipeline, so they'd never notice such a crime.
