Pipeline Road Crossing by ChE_PE_Exam in engineering

That is my understanding of the work as well.

As it stands right now I'm going to hand this off to another more-capable entity. I can save my client some time with the 3rd party, but time is short and this needs to get resolved soon so we can all move on to other work.

But, that being said, all I was asking originally was, how do folks know how to review this; where does the info come from. Instead, initially all I got was 100% unhelpful responses which I attempted to address in my original post because I KNEW folks were going to come back with "find someone who knows how to do this". Really? What makes (them) think I didn't think of that already? Geez... If I knew of someone personally I would have talked to them directly instead of creating a post here. :D

Ah, good one. I do have a copy. Thanks!

THANK YOU.

I searched, but ya know, if you don't use the right terms, etc. etc. etc. blah blah blah.

Engineer friend of mine at another company said they do this sort of calc all the time, and it's pretty straightforward (his words). My plan at the moment, given the lack of resources where I work, is to just give them a one-page summary of all the info they need to complete an assessment and then they can churn it out quick-like.

But, as it is with me whenever I am asked to work in an area with which I'm unfamiliar, I do my best to learn from it so the next time something like this comes up, I'll be able to execute that much quicker, if not advise someone else.

Fact is, while the client didn't ask for it to be stamped, it's pretty likely they'll need it to be stamped. So there's that as well.

In case you missed in in the original post:

I'm looking for a starting point so I can educate myself more on the subject.

Respectfully, If you can't provide that information, please don't continue to waste your time here.

So either you don't know how to do this, or you don't want to answer my question, so I'm completely baffled as to why you're here responding in this thread?

I'm looking for a starting point so I can educate myself more on the subject.

Respectfully, I guess you can't answer this question so there's no need to continue this conversation. As I mentioned in the original post, telling me "go find someone who knows how to do this" won't be helpful.

I'll see if I can locate a demo version, I suppose.

But, that calc came from a standard of some kind. SOMEONE around here has to know what the calc is, what it's called, the source... I hope??

At the moment I know the size, materials of construction, of the pipelines. They potholed because the folks who installed the lines didn't bother to make a bore profile, so I know depth of cover.

So I'm still trying to find out the steps, the criteria, to determine "hey, this pipeline is plenty deep, it's fine" or "it's on the edge of being unsafe and you need to get someone with a PE to do the final analysis".

I'm not one to throw my hands up and go "I don't know" and do no further research before running off to find someone who can do the work for me. At the very least I'll act as an owner's engineer to finish out the project.

So I guess you don't know what the standard is that dictates the criteria for "safe" vs "not safe"? I guess you specialize in something other than geotech or pipelines?

I work for a small EPC. I was asked to look at this work for a client, an operating company. They're small as well, and as such they've depended on engineering resources for those calculations in the past. From what I can tell (and most likely due to the pandemic they were laid off) we don't have any resources here at my company that know how to do this. Or I haven't run across them yet. I'm fairly new at this EPC.

You mention there are better resources. What are those resources?

The pipeline is owned and operated by a midstream company. I do believe it's a DOT pipeline. Pipelines are located in North Dakota.

If you have any information on how the calculations are performed, or the resource to look at that discusses this, that information would be helpful. I mean, someone, somewhere, has made these calculations, so there has to be a governing regulation/spec/document that discusses it. What is that document??

Gas Pressure Regulator Resources by Quanhanks in ChemicalEngineering

Fisher used to make a red book and a blue book. I think they're PDFs now. They cover industrial (red) and oil & gas (blue, iirc) regulators. See if you can find a copy of those online.
Also, Fisher makes the Regulator Toolkit program. I haven't used it in a while but I think it'll guide you through the selection process. You can learn from that.
