Paper presented at the PSIG Annual Meeting, May 16–19, 2023
Paper Number: PSIG-2315
... Abstract When a simulator is configured for an existing pipeline, it always needs adjustment to get it reproducing the line’s exact behavior. The engineer must determine unknown quantities such as pipe roughness and ground thermal parameters, but also identify which things they think they know...

... Greenfield and expansion pipeline projects pipeline roughness. Absolute pipeline roughness of 0.0018 inch (0.04572 mm) is often selected by default based on published industry information for hydrocarbon liquids. In practice, default pipeline roughness can be shown to vary based on product when pipeline...

The challenge lies in the fact that measured data all contain varying degrees of uncertainty, and the system becomes more...
