abstract

Many considerations go into the design of liquid pipelines relative to the placement of valves. Proper consideration of this issue must address not only minimization of capital costs, but the minimization of potential environmental and safety consequences. Critical to minimizing operating risks is the impact of valve placement on the potential outflow during a loss of containment event. In order to optimize the placement of valves in a pipeline, the effectiveness of each of many potential valve placement combinations must be measured by properties of the potential spill behaviour (i.e., average spill volume, peak spill volume, and HCA impacts). Factors affecting spill volume are topography, product properties, detection periods, valve closure timelines, and pump shut-down behaviour. This paper presents a solution to the challenge of optimizing valve placement in both interconnected and isolated systems through iterative generation of valve placement scenarios and hydraulic modeling. Various considerations that designers and operators should address are presented, along with results that are calibrated against real-world incidents.
