Pipeline Configurations A pipeline network is composed of:
injection points: inlet stations where the products are lifted into the line, storage facilities such as tanks and booster pumps are located there.
Delivery points: terminal, product will be delivered to the final consumer or to the other pipeline
Intermediate station: can provide a side stream injection or delivery point
pump stations: located along the line to move the liquid through the pipeline
Block Valve Stations: 1st line of consequence mitigation for pipelines. any segment can be isolated. they're located every 20-30 km
Regulating station: valve station where either pressure or flow is controlled. pressure regulates are located on the downhill side of a peak and flow regulates are found at delivery.

Side Stream Delivery:
dependent on:

delivery flow requirements
availability
nomination status
pipeline operational status

design operations :

Strip delivery through the branch line or at delivery point
ful stream delivery through the branch line
ful stream delivery through the main line

design considerations:

satisfying the delivery pressure requirements at both delivery locations while maintaining sufficiently high pressure at the take off point
using a pipe with a smaller diameter downstream of the delivery point if side stream delivery volume is large
installing an extra facility such as a pressure regulator or pump at the take off point on the branch line to stratify delivery pressure requirement
selecting pumps to meet the maximum and minimum flow requirements: if inlet is shut down flow rate can be lower than side branch flow rate
