About Pipeline Series
When a discontinuity occurs in a pipeline, use Pipeline Series to adjust facility numbers on the pipeline. A discontinuity typically occurs when an extension is added to the pipeline; the pipeline is re-routed; or when a company designates two pipelines as parallel lines. Instead of physically renumbering pipeline location numbers on-site, Pipeline Series allows you to shift pipeline numbering in PCS Axis using Relative Milepost locations.
A Pipeline Series is an ordered list of milepost locations with a starting milepost and an ending milepost that serve as connectors to preceding and subsequent Pipeline Series. All Pipeline Series snapped end to end map the pipeline. Multiple connected Pipeline Series form a Pipeline Series chain.
Additional characteristics of Pipeline Series include those in the following list:
• All facilities on the pipeline must be assigned to a Pipeline Series when a Pipeline Series is used with a segment of the same pipeline. An entire pipeline can be made up of several Pipeline Series.
The starting milepost of a Pipeline Series corresponds to the starting milepost for a segment of the pipeline. The ending milepost of the Pipeline Series corresponds to the ending milepost for the same segment of pipeline. Each Pipeline Series joins together, end-to-end, to make up the entire pipeline. Pipeline Series defines each segment and is then used to calculate the Relative Milepost.
• A pipeline with several different numbering schemes can be converted into a sequential line using a Pipeline Series for each segment of the pipeline. This allows you to graph the entire distance of the pipeline using the Relative Milepost.
• Pipeline Series supports negative milepost locations. This helps identify milepost locations that are in an opposite direction of other milepost locations in a series.
• Red facility records in a data entry grid identify milepost numbers that require a Pipeline Series be applied to the record.
