Background

The project includes three pipelines: a 34-mile crude oil pipeline connecting the LOCAP Oil Terminal to Motiva’s Norco Oil Refinery; a 12-inch, 35-mile pipeline connecting the Norco Oil Refinery and Motiva’s Convent Oil Refinery; and an additional six-inch, 34-mile pipeline between the two refineries.

Construction began in 2015. According to the Quanta Services Inc, responsible for permitting and construction, the project was completed in 2017.

Ownership

In October 2018, SemGroup sold 49% of its interest in the Maurepas Pipeline to investment funds managed by Alinda Capital Partners for $350 million. SemGroup will remain the majority owner and operator of the pipeline system, which consists of three separate transportation pipelines serving refineries in the Gulf Coast region of Louisiana.
