United States
Founded

Cayenne Pipeline, LLC is a Delaware registered company whose single asset is the Cayenne pipeline, a natural gas liquids line in southern Louisiana. It moves mixed NGLs from the gas processing plant at Venice, near the mouth of the Mississippi, to an interconnection with a third party NGL pipeline at Toca, from where the barrels travel on toward fractionation. The line was originally a natural gas pipeline and was converted to liquids service, entering operation in that role on 28 December 2017. The venture was formed in August 2017 when American Midstream Partners brought in Targa Midstream Services as a partner in what had until then been a wholly owned subsidiary, the two agreeing to share the conversion and construction costs, with Targa acting as operator of both the pipeline and the venture. The pipeline is registered as a common carrier with the Louisiana Public Service Commission rather than being regulated by FERC.

Where each figure comes from

A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.

What this page is not

It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Cayenne Pipeline, LLC where a holder stated one, and are missing where no holder did.
