Batch Tracking terminology

Anomaly

An anomaly is a mark used by the Batch Tracking application to track a point of interest in the fluid stream. An anomaly displaces a negligible volume, but moves through the pipeline system together with the batches.

Batch

A batch is a movement of a product, crude oil, or chemical feedstock consisting of only one product type.

Fragment

A fragment is a contiguous portion of a batch that exists in one pipe segment. A batch consists of one or more fragments, depending on the number of pipe segments that it currently spans.

Legs

A leg is the length of pipe between two profile points. The term "leg" can refer to both the pipe and to the fluid contained within the pipe. A pipe segment contains one or more legs. Legs do not span pipe segments.

Node

A node is a location on the pipeline system that is connected to one or more pipe segments.

Pipeline System

A pipeline system is an autonomously operating pipeline that consists of a network of pipe segments bounded by flow meters at the extreme ends. A pipeline system may consist of several receiving and delivery stations, as well as connected pipes.

Pipe Section

A pipe section consists of one or more pipe segments grouped together as required for your convenience. Linepack values are summed for all the pipe segments in a pipe section.

Pipe Segment

A pipe segment is a piece of pipe with constant capacity and uniform characteristics, such as pipe wall thickness and outer diameter. Pipe segments must be joined either to other pipe segments or to nodes.

Profile Point

Profile points are locations on the pipeline at which elevation is configured. At the profile points, temperature and pressure values are calculated or measured. Profile points exist at both ends of all segments, and are configured at other locations as required.

Station

A station is a collection of one or more nodes that represent a physical station. Station records are used to identify the meters, nodes, and so on, that exist at a physical station, both for reporting purposes and for use by other applications.
