Generic Spec - Oil&Gas

[digitalsurveys]

Hi all,

We've been carrying out a lot of scanning work in the heritage sector but are now looking to get more involved in industrial applications. English heritage have a generic spec for any heritage work, is there an equivalent in the industrial sector?

Are there any QA bodies that have generic specs or does it all depend on the project?
Also how do people account for data voids in pipe runs etc where you cant see, is this something included in the spec for example allowing for 10% data voids ?

Many Thanks
Ben

Hello Ben,

Specs are based on the plant its self as in a pipe number will be normally broke down so 15BD150-4"-A2 is really 15 is the plant number BD is blow down so the process 150 is the tag number and 4" is size and A2 is the spec and in a plant there can be over 50 specs. I think if you are wanting to draw up Plants from Laser scans 2 things you need are the P&ids and the specs for the plant without those two things its alot of work trust me

also with the voids bit that is something you will have to make sure is written up in the contact to start

Hi Ben,

I've done a lot of work on Oil & Gas projects, give me a call and I'll answer as many questions as I can.

I concur on this - Luke knows an awful lot about this sector and it would be well worth discussing it with him.

All the best for your future work!

In my experience, models will only be required for pipe engineers to route new pipes through existing plant.

Small plant locations will be better for intelligent models rather than large areas. Remember that when you deal with a large site, there are many engineers involved and they all have a different goal in mind.

If you are trying to generate an intelligent model from a refinery, then good luck, nobody has yet.

Dont get me wrong, I think that having an as-built model of a plant that can be used as a magament tool is a great idea. But thats all it is right now, an idea.

My advice is do what you know you can do and keep it simple or you will be in a world of pain.

Sorry Matt,

But i dont think what you said is true as we have a model with over 4000 pipes in and 1000 bits of equipment in are software with fully working specs and a full 3D model so i really think it can be done we can also go down to one valve and find everything about it and all costs area done and parts list. so not just a 3D model is a management tool to.

Hi Matt,

Do you mean an entire refinery? There have been quite a few laser scanning projects where "intelligent models" have been created from refineries but I'm not sure that an entire facility has been done yet. I'm sure we all know how large and complex these places can be.

Also dont forget that companies are already using models for management operations on lots of facilities including large refineries, the difference being that the model is usually based on "as designed" plant created during the design process and not necessarily "as built" models created from measured or scanned survey information. This is particularly true for facilities designed and built within recent years ( we worked on one particular LNG plant in Pakistan that was very new and the full design model was available in a PDS format to all the engineers working on any projects at the site).

I think that the biggest thing to get your head around on these projects is understanding the customers requirements, which as Matt suggested can be a problem on a large site because there are so many departments and organisations involved. Once you've cracked this then you can work with your customers to design a solution that works for them.

Hi Again luke,

what you say is true but as you seen we had are plant drawn that was a working as built model, we have now converted that too are new software so we have a as built plant running in a management tool as its now broke down into different areas. 1. is just a view so can see pipe and vessels 2. is the design side to add or change old pipes mainly used for engineers 3. a ISO and section part and final a costing a weight part. This software tags every part of the plant and works well. So i do believe Luke that is a as built plant in a PDMS system. I do agree tho it is alot to do with what the custmer wants that is why we broke are software up so can give people what they need.

plus all you need with our software is a center line so that means from any scan of any plant with any software out you can get the center lines from the scan of a as built plant and even if the plant has no documents you can work backwards and get the specs for each line and ISOs and soon P&IDs with only a scan.
