1. A method to stabilize flow in a pipeline, the method comprising:
flowing a fluid flow through the pipeline, the pipeline defining a fluid flow path therethrough;
analyzing the fluid flow to detect a non-optimal flow pattern;
determining a location within the fluid flow path to anchor a chokeable pig based on the non-optimal flow pattern;
launching the chokeable pig into the fluid flow path after detection of the non-optimal flow pattern and determining of the location;
anchoring the chokeable pig at the location; and
adjusting the fluid flow through the pipeline.
