I've been communicating with Steven Kohlhase since I first spotted this:

Steve has a very interesting theory that some pipeline failures are caused by
low-frequency mechanical vibrations in the pipeline itself, which can be
first heard and felt. Over times, these vibrations might lead to weld failures,
and catastrophic ruptures.
We've been discussing the likely cause of these vibrations.
So far, it seems the likely source to be one or more of the following:
- Vibrations which originate in compressor stations, then form destructive
"resonant tanks" due to the physics of pipelines. (Think if a pipeline as
being analogous to a giant piano string) - Vibrations which occur due to internal frictional forces.
- Vibrations which are caused by Cavitation or Fluid-Hammer

- http://en.wikipedia.org/wiki/Water_hammer
- Cavitation is a problem with high-viscosity high-pressure
Dilbit (tar sands) pipelines, like the Keystone XL:

If his theory is correct (and I think there is certainly something to it)
this could mean that ALL PIPELINES are subject to
random catastrophic failures over time.
This could also explain the many reported weld failures in the Millennium Pipeline.

Here is Steven's latest filing with FERC (it's big... 2.5mb)

Please send this to other groups fighting compressor stations or pipelines.

Hi Bill, just quickly scanned and will revert back later today (have a honey do list right now). I will definetly comment. On MOnday I filed a formal complaint to FERC- attached.
