Robotics ROI at Refinery Scale:
Marathon Garyville
Marathon Petroleum's Garyville refinery, on the Mississippi River in St. John the Baptist Parish, is publicly reported at approximately 600,000 barrels per day of capacity — consistently ranked among the largest refineries in the United States. Facilities at this scale make the ROI case for autonomous inspection, security, and warehouse robotics unambiguous, and Actel Robotics serves the greater New Orleans river-parish corridor it sits in.
A Benchmark Refinery on the Mississippi River
Publicly available sources place Garyville's refining capacity at roughly 600,000 barrels per day, with public reporting consistently describing it as one of the largest refineries in the country (exact published figures vary somewhat by source and shift over time with expansions and turnarounds). The site is reported to employ approximately 900 direct personnel, supplemented by several hundred contract workers who support ongoing operations and periodic turnarounds.
Garyville sits in St. John the Baptist Parish, part of the greater New Orleans metropolitan area, roughly midway along the river corridor between Baton Rouge and New Orleans — one of the densest refining and petrochemical regions in the country. A facility of this scale is a useful reference point because it illustrates the same automation logic that applies, at smaller scale, to mid-size refineries and chemical plants across Texas, Louisiana, and Oklahoma.

Where Automation Pays Off in a Large River-Corridor Refinery
Inspection Coverage
Thousands of inspection points across process units, tank farms, and pipe racks limit manual inspection frequency to what labor cost and hazardous-zone access allow. Autonomous robots remove both constraints.
Riverfront Perimeter Security
A riverfront footprint with dock, rail, and pipeline infrastructure creates a large, irregular perimeter that is expensive to patrol continuously with people alone.
MRO & Spares Warehousing
Turnaround planning depends on knowing exactly what parts and materials are on hand, where, and in what condition — a warehouse automation and inventory-accuracy problem at real scale.
Robotics Built for This Environment
Autonomous Inspection in High-Hazard Process Units
Spot conducts thermal, visual, and acoustic inspection rounds in energized zones, toxic atmospheres, and confined process areas — building an audit-ready inspection record without repeated human entry.
All-Terrain, All-Weather Perimeter Coverage
Vision 60 and Asylon's DroneDog and Guardian system extend continuous coverage across large, irregular riverfront perimeters — in Gulf South heat, humidity, and rain — at a fraction of the cost of a comparable human guard force.
Serving the Greater New Orleans River-Parish Corridor
Actel Robotics is based in Sugar Land, Texas and actively serves the Louisiana river-parish corridor — from Baton Rouge to greater New Orleans — as part of its broader Texas, Louisiana, and Oklahoma coverage area.
Marathon Garyville & Refinery-Scale Robotics — FAQ
Is Actel Robotics affiliated with Marathon Petroleum or the Garyville refinery?
No. Marathon's Garyville refinery is referenced here as a publicly known example of refinery scale on the Mississippi River corridor Actel Robotics serves. Actel Robotics is an independent, authorized robotics integrator and is not affiliated with, endorsed by, or a vendor to Marathon Petroleum unless a specific engagement is separately disclosed.
How large is the Garyville refinery?
Public sources place Garyville's capacity at approximately 600,000 barrels per day, consistently cited among the largest oil refineries in the United States, with roughly 900 direct employees plus several hundred additional contract personnel supporting operations. Exact published figures vary slightly by source and change over time with expansions.
What kind of robots suit a large river-corridor refinery?
Boston Dynamics Spot for thermal, visual, and acoustic inspection inside process units and hazardous zones; Ghost Robotics Vision 60 and Asylon's DroneDog and Guardian system for all-weather perimeter security across large, riverfront footprints; and warehouse-side automation for MRO parts and spares inventory supporting turnaround planning.
