Marathon, Garyville Platformer Heater

Location: Marathon, LA

WORLD’S LARGEST PLATFORMER HEATER, VARIOUS OTHERS

Marathon embarked on the Garyville Major Expansion project (GME), one of the largest refinery expansions in U.S. history. The GME project was conceived as a way to enhance the refinery’s ability to adjust feed-stocks and yields, and to make rapid production changes according to market shifts. The GME increased Garyville’s production capacity by 180,000 barrels to 436,000 per day, making it the fourth largest refinery in the country.

OnQuest was retained by Marathon to design and build nine separate heaters for Garyville. Our scope including engineering and installing the world’s largest heater.
