Thanks BibInch and zdas04 Among the references I have found on the internet on the topic, the "Introduction to Pipeline Economics - Presentation" by Tom Miesner is interesting. Thanks again. Sam066

Hi all, I am looking for information on pipeline construction and operations life cycle costs. I have heard about a ratio of around 15% for construction and 85% for operations over a 30 year span. I understand that this ratio could vary depending on pipes, product, etc. Has anyone got any...

To cloa (Petroleum) "how good will this drying be" That's the question

Re-thanks. One more question though. What would you fire the PM? Sam

Thanks zdas04 for your input, How would you ideally deal with this situation knowing that the pipeline commissioning will take place from one to two years after the construction is completed? Sam

urquiam, I am not really aware of any detailed code or procedure (that would be public) that deal with this kind of operation (cut-out and tie-in). Regardless to the length of your spool, and I am sure that you are aware of that, one has to be aware that any hot work, performed on a hotline...

Thanks pmover, It's a fairly long pipeline & big inch, but the pressure and drying are done on sections of pipe anyway. I'll reformulate my question: Because of the use of a water/methanol mixture during the pressure test, and as the drying may not allow us to get rid of all water/methanol...

Hi all, Is it recommended to run a batch of corrosion inhibitor (oil-based for instance) after hydrostatically testing a pipeline with a water/methanol mixture in case the pipeline commissioning is delayed or a pipeline drying may be sufficient to get rid of the water/methanol mixture? Thank...
