New info in the Salem, Westmoreland Co., PA failure of the TETCO (Spectra).
And Spectra took no action.
Andy Drake, vice president of operations for the Houston-based company, says the corrosion was revealed during a 2012 inline-pipeline inspection. It showed a 30 percent decrease in the thickness of the pipeline's wall.
"It was very small. It was smaller than any threshold we would have been required to [take] action on or investigate," Drake says. "The anomaly grew at a significantly higher rate than anything we've seen in the past."
Spectra says, essentially, it failed sooner then we expected.
Wow. 30% wall loss seems like significant corrosion to me.
Why did Spectra do nothing?
but is astounding from a pipeline safety perspective.
Sweet baby Jesus.
So he is implying, something site-specific happened since 2012
even with best technology in 1981 inc. CP,
and a spot of 30% loss is non-actionable... wow.
- 1) wet areas (e.g., creekbeds)
- 2) within 5 miles downstream of a compressor
- 3) nearby sources of stray DC, such as CP systems from foreign pipelines (at crossings and/or co-located ROWs), bridges, railroads, storage tanks, or other sites where CP is used.
May you, and all beings
be happy and free from suffering :)
