Pipeline corridor width for oil and gas pipelines

A unique corridor is not always possible.

International standards and guidelines will exist but I think each country should adopt law suiting there own situation.

In SA we have:

A pipeline act dealing with gas/oil/petrol pipelines.

A Water act dealing with water resource crossings and water pollution spills.

An environmental act dealing with environmental issues.

And law dealing with servitudes where private land must be crossed.

Thanks for your prompt reply. I would be expecting more information on the subject !

I think you should contact your local / national environmental authorities first.

Then tell us what you have and what more you need.

Hi,

I believe that you can seek advice from government authorization organ or international register such as Lloyd's, DNV, ABS. Anyway you could find suggestion in API 1104 and/or DNV 2000. It depend on where is your pipeline: offshore or inland?

Regards,

For cross country hydrocarbon pipelines to be laid in parallel in the same trench, the minimum clear distance between the pipelines being considered is generally 500 mm.

Regards

U r correct, the min distance between pipes shall be 500mm, this again will vary depending on the code and local standards if followed. Sometimes it will be taken to be 2 times the dia of the pipe or 500mm whichever is greater. The main reason for providing would be the the CP system, the two pipes if comes in contact then there would be corossion. To avoid this clerance has to be provided.

My dear

To find the solution, you are kindly requested to read -at least- the following codes and standards :

• ASME Codes for oil and gas Pipelines

ASME B31.4 Liquid Transportation Systems for Hydrocarbons, Liquid Petroleum Gas, Anhydrous Ammonia and Alcohols.

ASME B31.8 Gas Transmission and Distribution Piping Systems. nnASME B13.1 Scheme for Identification of Piping Systems.

• API standards for oil and gas pipelines
