The Pipeline Analysis Code, PLAC, is utilized to study the flow generated from a shallow dip in a long pipeline. It shows that much longer and infrequent slugs are formed when liquid is swept out of the dip than would be expected from horizontal pipeline data. These slugs eventually propagate along the entire length of the pipeline. These dip-induced slugs are similar to the one-in-a-thousand slugs reported from existing long pipelines.
