Key Facts
Site Overview
The Phillips 66 Sweeny complex includes a refinery with approximately 265,000 barrels per day capacity and integrated petrochemical operations. Located in Old Ocean, Texas, the facility sits in rural Brazoria County about 60 miles south of Houston. The refinery produces gasoline, diesel, jet fuel, and petrochemical feedstocks for the adjacent chemical plants.
Maintenance Organization
Sweeny's maintenance organization is led by a Maintenance Manager overseeing area superintendents for both refining and petrochemical operations. A dedicated reliability engineering team manages condition monitoring, failure analysis, and maintenance strategy across the complex. The turnaround planning group coordinates shutdowns for both the refinery and chemical units.
Procurement and Vendor Management
Phillips 66 operates a centralized procurement organization with corporate category managers in Houston. The Sweeny site maintains local buyers for daily MRO purchasing and expediting. Vendor qualification requires corporate AVL approval, which includes safety prequalification, financial review, and quality system assessment.
Integrated Operations
The integration between refining and petrochemical operations creates interdependencies that affect maintenance scheduling and turnaround planning. A turnaround on the olefins cracker impacts feedstock supply to the polyethylene units, requiring coordinated planning across both sides of the complex. This integration also means vendors must often qualify for both refining and chemical operations.
