... and 60 deg F to maintain similarity between cases. In the sections below we examine the pressure profiles that would exist in the pipeline following a leak event: 25 mmscfh Leak on Zero Initial Flow Figure 13 shows the pressure profile every 2 minutes for the first 10 minutes following the onset of a 25...

... will be considered first with a specific focus on the crude export pressure profile registered at the Tartan platform. This is depicted in Figure 19, where the sequence of known events is super-imposed on the pressure traces. Multiple scenarios were studied wherein different sizes of leaks were modeled in order...

... is to understand how the flow and pressure profiles evolve both spatially and temporally after an event, to help dispatchers have a better understanding of events and fluid dynamics within the pipes. 1.2. EQUATIONS FOR THE BASIC SCENARIO Doing the same hypothesis and variable changes as in [2], the 1-dimensional...
