There is some regulation to justify that the pipeline does not need to be buried

There is some regulation to justify that the pipeline does not need to be buried

(OP)
I am in the process of designing a line of flow for crude with 6 "pipeline, the terrain where the pipeline route is designed has a very rugged geography, which would make trenching difficult, I have existing H frame supports, besides The local conditions do not present very high temperatures nor very low, for this reason the preliminary proposal was that the pipe is AG "Above Ground", however the client wants the pipe to be buried for this reason consulted if it exists in some regulations or some paper of good practices Some support to indicate that my pipe can be aerial.I appreciate your help.

RE: There is some regulation to justify that the pipeline does not need to be buried

bvrs,

If the terrain is very rugged and difficult to trench, then it will be equally difficult to build your supports at ? spacing. Or are they there already?

Regulations are specific to your location and need to be discussed with the relevant authority - you don't say where you are.

Design codes for pipelines recognize that most pipelines are buried for reasons of safety, continuous support, visual disturbance, disturbance to agriculture, animals and people traversing the pipeline, however also recognize that some pipelines are above ground.

Clearly the Alyeska pipeline (TAPS) on the north slope is a classic example, but many above ground pipelines existing in the Middle East.

RE: There is some regulation to justify that the pipeline does not need to be buried

It is unlikely that you will convince your client to change their mindset. In fact most regulations call for burial, except in very unusual circumstances. It is also unlikely that construction and burial is as difficult as you profess. Pipelines left on the surface are extremely vulnerable to many different factors, washout, sliding, subsidence, coating damage, terrorist and vandal activities and they are not environmentally friendly, as they make a formable barrier that many animals cannot, or do not like to cross, or make things extremely difficult, or inconvenient to cross. Nothing makes someone as mad as having to drive 2km or more one way and the same again back to cross a pipeline at a designated crossing point.

If you can say where is this pipeline is being built, there is a slight chance that I may be able to give you some local examples where pipelines were installed above ground, or tell you some specific reasons why it could be an extremely bad idea.

LittleInch and BigInch, on the route we have existing supports within the right-of-way, in access to housing and at road junctions the pipeline is designed as buried, however the question is because most of the pipeline is designed above ground Due to the difficult maneuverability of machinery to perform the trench, we also want to avoid cathodic protection if we have buried pipe, with respect to cathodic protection: if I have pipe is above ground, would also require cathodic protection?

What's on the existing supports?

The key risk is accidental or deliberate damage and the impact on the people and land around them.

If there are flowlines there now, what's the issue?

We are going to replace an existing line but now the client requests that it be built buried, and for that reason I need to justify that the pipe should be above ground

RE: There is some regulation to justify that the pipeline does not need to be buried

If you buried it would you remove the supports or are there other pipes on it.

Just give him the costs of the two options and let him choose - his money.
