Texas Refinery Turnaround Schedule 2026: Facility Windows, Procurement Timelines, and Vendor Positioning

Every year, refineries and petrochemical plants along the Texas Gulf Coast shut down major process units for planned maintenance. These scheduled outages, known as turnarounds, represent the largest concentration of procurement activity in the energy sector. For vendors selling equipment, services, or materials into these facilities, understanding when turnarounds happen is the difference between a pipeline full of orders and an empty quarter.

The challenge is that no refinery publishes its turnaround schedule publicly. Turnaround timing is considered competitive intelligence because it affects product supply, regional pricing, and contractor availability. What follows is a framework for understanding how turnaround cycles work in Texas, which facilities are most likely in a turnaround window in 2026, and how vendors can position themselves before the spending begins.

How turnaround cycles work

Most large refineries operate on a 4 to 6 year turnaround cycle for major process units. A crude distillation unit that was last turned around in 2021 or 2022 is likely approaching its next major outage in 2026 or 2027. Fluid catalytic cracking units, hydrocrackers, and reformers each run on their own cycle, which means a single refinery may have multiple turnaround events in any given year, staggered across different units.

The Gulf Coast turnaround season historically concentrates in two windows. The spring window runs from late February through May, after winter demand for heating fuels subsides and before summer gasoline demand peaks. The fall window runs from September through November, after summer driving season ends and before winter heating demand returns. These windows exist because refiners want to avoid taking capacity offline during peak demand periods when margins are highest. For a facility by facility breakdown of the upcoming fall window, see the Gulf Coast fall 2026 turnaround schedule.

That said, the traditional two window pattern has shifted in recent years. Refiners increasingly schedule turnarounds based on equipment condition monitoring data rather than fixed calendar cycles. Predictive maintenance programs using vibration analysis, thickness monitoring, and process data analytics allow some operators to extend run times beyond traditional intervals, while others pull turnarounds forward when inspection data reveals accelerated corrosion or equipment degradation.

Facilities likely in turnaround windows in 2026

Based on publicly available information including permit filings, contractor mobilization patterns, and industry reporting, several major Texas facilities are expected to have significant planned outage activity in 2026.

The ExxonMobil Beaumont complex, one of the largest integrated refining and chemical operations in the Western Hemisphere, typically staggers turnarounds across its refinery, chemical plant, and polyethylene units. The Beaumont refinery processes over 360,000 barrels per day of crude oil. With the last major crude unit turnaround believed to have occurred in 2022, a 2026 event is consistent with the typical cycle. ExecGraph tracks over 700 contacts at the ExxonMobil Beaumont complex across operations, maintenance, engineering, and procurement.

The Valero Port Arthur refinery

is one of the largest in North America at approximately 395,000 barrels per day. Valero operates on disciplined turnaround cycles and discloses aggregate turnaround spending in quarterly earnings calls without specifying which facilities are involved. Based on the typical 4 to 5 year cycle for major units, Port Arthur is within the expected window. ExecGraph maps 267 contacts at Valero Port Arthur including operations managers, turnaround coordinators, and procurement leads. See the full Valero Energy org chart for the complete decision chain.

The Motiva Port Arthur refinery, owned by Saudi Aramco, is the single largest refinery in the United States at 630,000 barrels per day. Motiva has historically scheduled major turnarounds in alignment with Saudi Aramco's global maintenance planning cycle. Turnaround activity at this facility creates significant demand for scaffolding, heat exchangers, rotating equipment services, and catalyst handling. View the Motiva Enterprises org chart to map the decision chain.

The TotalEnergies Port Arthur complex includes both refining and petrochemical operations producing polypropylene, HDPE, and aromatics. TotalEnergies has been investing in reliability improvements across its Gulf Coast portfolio, and scheduled maintenance at Port Arthur typically involves both the refinery and the adjacent chemical units.

The Marathon Galveston Bay refinery in Texas City, formerly the BP Texas City refinery, processes approximately 593,000 barrels per day. Marathon acquired this facility in 2013 and has invested heavily in upgrades. Major unit turnarounds at this scale facility involve hundreds of contractors and tens of millions of dollars in materials procurement. See the Marathon Petroleum org chart for operations and maintenance leadership.

What turnarounds mean for vendors

Turnaround procurement typically begins 12 to 18 months before the execution date. Long lead items like heat exchanger bundles, large bore valves, specialty alloy piping, and catalyst loads are specified and ordered more than a year in advance. Services like scaffolding, crane rental, NDT inspection, and specialty welding are contracted 6 to 12 months ahead.

The procurement chain for a major refinery turnaround follows a predictable sequence. The turnaround manager and planning team develop the work scope 18 to 24 months out. Engineering reviews and material takeoffs happen 12 to 18 months out. Purchase requisitions flow to procurement 9 to 15 months out. RFQs go to vendors 6 to 12 months out. Material deliveries and contractor mobilization happen in the 3 months leading up to the outage.

For vendors, this means the window to influence a turnaround is not during the turnaround itself. It is 12 to 18 months before execution, when the work scope is being defined and material specifications are being written. The contacts who matter during this phase are turnaround planners, reliability engineers, maintenance managers, and rotating equipment engineers, not the procurement department. By the time a purchase order reaches procurement, the specification is locked and the vendor selection is largely decided.

How to position for turnaround business

The most effective approach is to build relationships with turnaround planning teams and reliability engineers well before the outage cycle begins. These are the people who decide which equipment gets replaced, which repairs get specified, and which vendors get invited to bid.

ExecGraph maps the complete organizational structure of every major refinery and chemical plant in Texas, including turnaround planners, reliability engineers, maintenance managers, and the procurement contacts who execute the purchase orders. The platform identifies warm path connections between contacts at different facilities, showing where career overlaps create introduction opportunities.

Understanding who is responsible for turnaround planning at your target accounts, and reaching them 12 to 18 months before the expected outage, is the single highest value activity for any vendor selling into the Texas refining sector. The turnaround schedule may not be published, but the organizational structure and the people behind it are knowable. Start your free trial at execgraphenergy.com/trial.

Frequently asked questions

When is Texas refinery turnaround season in 2026?

The Texas Gulf Coast turnaround season concentrates in two windows: spring (late February through May) and fall (September through November). Major process units at facilities like ExxonMobil Beaumont, Valero Port Arthur, and Motiva Port Arthur operate on 4 to 6 year cycles, with several facilities expected to have significant planned outage activity in 2026.

How far in advance do refineries procure turnaround materials?

Procurement begins 12 to 18 months before the execution date. Long lead items including heat exchanger bundles, large bore valves, and catalyst loads are specified and ordered more than a year in advance. The turnaround manager and planning team develop work scope 18 to 24 months out, which means the window to influence vendor selection is well before the event itself.

Which Texas refineries are the largest by capacity?

The five largest Texas refineries are Motiva Port Arthur (630,000 bpd), Marathon Galveston Bay (593,000 bpd), Valero Port Arthur (395,000 bpd), ExxonMobil Beaumont (360,000 bpd), and ExxonMobil Baytown (584,000 bpd). Combined, the Texas Gulf Coast refining complex processes nearly 6 million barrels per day.

Who controls vendor selection for refinery turnarounds?

The turnaround manager and reliability engineering team control the technical specification and vendor shortlist 12 to 18 months before the event. Procurement executes the purchase orders but rarely overrides the technical team's vendor recommendations. Building relationships with turnaround planners, reliability engineers, and maintenance managers is the most effective path to turnaround business.
