Project Description

Marathon Petroleum completed the construction of a $3.7 billion mega project major expansion at its Garyville, Louisiana refinery.  As a result, the refinery's capacity was increased by nearly 180,000 BPD to 465,000, making this one of the top refineries in the United States. In all, eight new grassroots production units were added to this world-class facility. In addition, 1,200 pieces of equipment from twelve different countries were installed.
