For determining the optimum size and consequently the hydrodynamic performance of a pipeline, your best approach would be to initially obtain a pipeline size from a parametric study using one of the commercially available steady state hydraulic analysis tools.<br>
<br>
However for a complete analysis, you would be advised to employ a transient analysis tool which would provide a detailed pipeline pressure profile, liquid handling characteristic and other peretinent information for optimising the pipeline and designing the downstream reception facility. <br>
<br>
I work for a specialist company that provides engineering services for the design and installation of marine pipelines, not only for oil and gas applications but also for demanding special design considerations such as high pressure, high temperature, deepwater, arctic service or aggresive fluids. Our experience includes a number of pipeline design projects in the Caspian Sea. <br>
