Industry standard on pipeline crossing 4

[engr2GW]

Hi all,

what API or other documents (or other resources) can I consult to find industry standards on pipeline crossings. I'm more interested in finding useful information about pipeline crossing for buried (and may be above ground) pipelines.

There was an incident where a still pipeline was installed below an already existing fiber glass salt water line and the filling in between them was not compact enough, afte a few months, the soil inbetween them gave way and the fiber glass line deflected (sagged) to the point where it failed and caused a release. We are currently using sand bags inbtween the top and bottom lines, does any one have any recommendation or experience with that/

Thanks for your help.

As much as possible, do it right the first time...

Might work that way in the wild, wild west, but most civilized places in the world, ya can't do it thataway unless you like the inside of a jail cell.

I gotta say I like the wild wild west, civilized places don't sound like much fun.

LoL.

I can just hear John Wayne: "Well, pardner, do you want to cross my line or don't ya?"

OK, then maybe it's the other extreme here. If you try an unauthorized crossing around these parts, the natioinal guard's industrial defense forces shoot first and ask questions ... never.

Actually it's better yet not to even shoot pictures.

…to add a couple other notable quotes from the past,

“What we have here is a failure to communicate.”

( I of course didn’t say the new “crosser” would win any such arguments, just adding to the obvious that an initially chosen installed weaker pipeline had apparently, and perhaps not surprisingly considering the required over-excavation and structural weakness and unequal three-dimensional strength of such pipe, been compromised per the OP by the crossing that was apparently required to be close underneath.)

As to the new tag line of our most well-known responder, someone who can simplify or has enough knowledge and experience to make very complicated issues at least somewhat understandable for most of us admittedly more unwashed masses is indeed invaluable.

First break it down to extremely simple components and find the similarities. There's always more than the differences.

These days it seems a separate procedure is needed to paint something red, or paint the same thing green.
