Texas Refinery Turnaround Schedule 2026: Season Windows And Vendor Deadlines

In 2026, major Texas refineries are concentrating planned turnarounds in their usual spring and fall seasons, with procurement for critical materials and services starting 12 to 18 months before the outage date. Large crude and conversion units generally run on 4 to 6 year cycles, which puts several Gulf Coast complexes in active planning or execution windows during 2026.

This page summarizes how Texas refinery turnaround cycles work, which large facilities are likely in play during 2026, and when vendors must be in front of turnaround planners, reliability engineers, and maintenance leadership to win work.

Quick view: Texas refinery turnaround timing in 2026

Refinery turnarounds are planned outages for inspections, repairs, and upgrades that cannot be performed while units are online. Along the Texas Gulf Coast, these events represent one of the largest recurring procurement opportunities in the industrial economy.

ExecGraph also maintains a separate modeled schedule of 2026 events covering 12 turnarounds across 8 Texas facilities on the dedicated Texas turnaround schedule. This article focuses on how to use those windows and the underlying decision chain to position your offering.

How Texas refinery turnaround cycles work

Most large Texas refineries align their major-unit turnarounds with both long-run mechanical cycles and seasonal product demand. Understanding those two drivers is essential context before looking at specific facilities.

Typical outage windows along the Texas Gulf Coast

Historically, Texas Gulf Coast refineries concentrate planned maintenance in two main seasons to avoid pulling capacity during peak product demand.

• Spring window: The spring turnaround season generally begins in late February and runs through May. Refineries use this period after winter heating demand fades and before peak summer gasoline demand to take crude and downstream units offline.
• Fall window: The fall season typically runs from September through November. Facilities schedule work after the summer driving season but before winter distillate demand strengthens again.
• Demand and margin protection: These windows exist because taking capacity offline during peak seasonal margins would directly impact profitability and regional supply, so operators cluster major work in the shoulders of the year.

How 4 to 6 year cycles shape 2026 activity

Most major process units in Texas refineries operate on multi-year cycles that determine when large capital and maintenance work will next occur.

• Major crude units: Crude distillation units commonly operate on 4 to 6 year turnaround cycles. A crude unit with a major turnaround executed in 2021 or 2022 is statistically in range for another large outage in 2026 or 2027, depending on condition and commercial priorities.
• Conversion and treating units: Fluid catalytic cracking units, hydrocrackers, and reformers each follow their own cycles, often offset from crude units. This staggering can produce multiple turnaround events inside a single facility over a few years, each with its own procurement wave.
• Condition-based adjustments: Increasingly, Texas refineries adjust timing based on condition monitoring data rather than a fixed calendar. Predictive programs using vibration analysis, wall-thickness monitoring, and process analytics can safely extend runs or force earlier outages when inspection data indicates accelerated corrosion or equipment degradation.

The result for vendors is that 2026 is not defined by a single event or quarter. Instead, it is a cluster of turnarounds that align with these seasonal windows and unit cycles at individual sites.

Major Texas refineries likely in 2026 turnaround windows

ExecGraph surveys publicly available information such as permit filings, reported capital projects, contractor mobilization patterns, and industry reporting to identify facilities that are likely to have significant planned outage activity in 2026. The focus here is on large refineries where a single turnaround can translate into substantial procurement volume.

Combined, these refineries represent approximately 2.97 million barrels per day of crude capacity. The wider Texas Gulf Coast refining system processes nearly 6 million barrels per day when all facilities are considered.

ExxonMobil Beaumont complex

The ExxonMobil Beaumont complex is one of the largest integrated refining and chemical operations in the Western Hemisphere. The Beaumont refinery itself processes over 360,000 barrels per day of crude oil.

Based on historical patterns, ExxonMobil typically staggers outages across the refinery, chemical plant, and polyethylene units rather than taking everything down at once. Evidence from previous crude unit turnarounds indicates that a major crude event believed to have occurred in 2022 would be consistent with another large-scale outage entering its planning or execution window around 2026 or 2027.

ExecGraph tracks over 700 contacts at the ExxonMobil Beaumont complex across operations, maintenance, engineering, and procurement, providing visibility into the decision chain that drives turnaround scope and vendor selection.

Valero Port Arthur refinery

Valero's Port Arthur refinery is among the largest in North America at approximately 395,000 barrels per day of capacity. Valero publicly discusses aggregate turnaround spending in its quarterly earnings calls without specifying which refineries are involved.

The company is known for disciplined, repeatable turnaround cycles. On a 4 to 5 year interval for major units, Port Arthur is within a reasonable planning window for significant maintenance activity aligning with the 2026 spring or fall seasons.

ExecGraph maps 267 contacts at Valero Port Arthur, including operations managers, turnaround coordinators, and procurement leads. This coverage enables vendors to identify which roles influence scope definition, technical specification, and award decisions for turnaround work.

Motiva Port Arthur refinery

The Motiva Port Arthur refinery, owned by Saudi Aramco, is the single largest refinery in the United States with capacity of about 630,000 barrels per day. Its scale makes any major turnaround a regionally significant event for labor, materials, and logistics.

Motiva has historically aligned major turnarounds at Port Arthur with Saudi Aramco's broader global maintenance planning cycle. When large units are taken down, demand spikes for scaffolding, heat exchanger services, rotating equipment repair, and catalyst handling, among other specialized services.

ExecGraph's Motiva Enterprises organizational mapping allows vendors to view the broader corporate and site-level decision chain when targeting Port Arthur turnaround opportunities.

TotalEnergies Port Arthur complex

The TotalEnergies Port Arthur complex includes both refining and petrochemical operations. On-site units produce polypropylene, HDPE, and aromatics in addition to fuels.

TotalEnergies has been investing in reliability improvements across its Gulf Coast portfolio. At Port Arthur, scheduled maintenance often touches both the refinery and adjacent chemical units, creating cross-unit opportunities for vendors who can service multiple asset classes.

Marathon Galveston Bay refinery (Texas City)

The Marathon Galveston Bay refinery in Texas City, formerly the BP Texas City refinery, processes approximately 593,000 barrels per day of crude. Marathon acquired the facility in 2013 and has invested heavily in modernization and reliability improvements.

Major unit turnarounds at a facility of this scale involve hundreds of contractors and significant materials procurement. Individual events can require large volumes of specialty alloy piping, heat exchanger bundles, and rotating equipment work, alongside extensive scaffolding and crane support.

ExecGraph's coverage of the Marathon Petroleum organizational structure highlights operations and maintenance leadership roles that are central to turnaround planning and approval.

What a 2026 Texas refinery turnaround means for vendors

For vendors, a turnaround is not just an outage window on a calendar. It is a long, structured decision process that begins years in advance and passes through several internal gates before any RFQ is issued.

Typical 24 month turnaround planning and procurement sequence

While each operator has its own internal playbook, large Texas refineries repeatedly follow a broadly similar sequence for major-unit turnarounds.

• 18 to 24 months before execution: The turnaround manager and planning team develop the preliminary work scope. They review inspection histories, equipment condition data, and regulatory requirements to decide which units and components are in-scope.
• 12 to 18 months before execution: Engineering reviews and material takeoffs translate that scope into specific work packages. During this period, engineers and planners are highly receptive to technical input that can reduce risk, shorten duration, or improve reliability.
• 9 to 15 months before execution: Purchase requisitions are raised and move into the procurement workflow. Internal approvals and budget alignment take place, and preferred vendors may be identified for long-lead items.
• 6 to 12 months before execution: RFQs go out to vendors for materials and services. Long-lead items such as heat exchanger bundles, large-bore valves, specialty alloy piping, and catalyst loads are typically specified and ordered more than a year in advance.
• 0 to 3 months before execution: Materials deliveries ramp up and contractor mobilization accelerates. Scaffolding, crane rental, NDT inspection, and specialty welding crews are scheduled and staged for site access.

By the time a purchase order reaches a refinery's central procurement team, the technical specification and preferred vendor list are often effectively locked in by the turnaround and reliability organizations.

Who actually controls turnaround vendor selection

On paper, procurement issues the purchase orders. In practice, the most important vendor decisions for 2026 Texas refinery turnarounds are made earlier and by different roles.

• Turnaround managers and planners: Own the scope, schedule, and risk profile of each event. Their early choices determine which work is in or out, and whether existing vendors are rolled over or alternatives are considered.
• Reliability engineers: Evaluate inspection data, failure histories, and mitigation options. They often write or review specifications for equipment replacements and repair strategies.
• Maintenance managers and discipline leads: Mechanical, rotating equipment, instrumentation, and electrical leaders influence the selection of service contractors and equipment standards within their domains.
• Project and engineering teams: When capital upgrades are bundled into a turnaround, project engineers and managers add another layer of stakeholder approvals and preferred supplier lists.
• Procurement and category managers: Execute the commercial process, negotiate price and terms, and ensure compliance with corporate standards, but usually work within a vendor shortlist assembled by the technical and turnaround functions.

For vendors seeking 2026 work, concentrating outreach solely on procurement teams risks arriving after the real selection decisions are already made.

Vendor positioning playbook for 2026 Texas turnarounds

Winning Texas refinery turnaround business in 2026 is less about reacting to RFQs and more about aligning with the right decision makers at the right stage of the planning cycle.

1. Start with facility and unit timing

• Anchor on the 4 to 6 year cycle: Use the known or approximate date of the last major turnaround on your target units to estimate when they are likely to fall inside a 2026 or 2027 window.
• Overlay seasonal constraints: Expect large Texas refineries to keep crude and major conversion units online during peak winter heating and summer driving periods. Focus on the shoulder seasons described earlier.
• Use modeled schedules as a guide, not a script: The ExecGraph Texas turnaround schedule aggregates observable indicators into a 2026 event view across 8 facilities and 12 modeled turnarounds. Treat this as a planning compass for when outreach is most time-sensitive.

2. Map the turnaround buying center

• Identify function-specific decision makers: Within each target refinery, isolate the turnaround manager, event planners, reliability engineers, maintenance managers, and rotating equipment engineers who touch your product or service category.
• Distinguish corporate vs site roles: Some operators keep turnaround standards, preferred vendor lists, and major contract negotiations at the corporate level, while others empower site leadership. Understanding that split is critical for targeting effort.
• Leverage career paths and internal referrals: The ExecGraph platform maps where leaders at one facility previously worked, revealing warm-path introductions across Texas refineries and petrochemical plants.

3. Sequence outreach with the planning calendar

• Engage 18 to 24 months out for scope influence: This is when planners and reliability engineers are still open to alternatives that change scope, solution design, or bundling strategy.
• Target 12 to 18 months out for specification input: Bring case studies, inspection data, or engineering support that can shape how requirements are written and what performance criteria will matter.
• Maintain presence 6 to 12 months out for bid inclusion: At this stage the goal is ensuring your company is on the RFQ distribution and that key decision makers can distinguish your offer from incumbent suppliers.

4. Align your offer with turnaround risk and priorities

• Reliability over lowest price: For critical-path turnaround work, decision makers frequently prioritize reliability, safety performance, and schedule adherence over marginal cost differences.
• Schedule compression value: Offerings that shorten outage duration or reduce rework can be compelling when planners are trying to protect throughput during shoulder seasons.
• Multi-discipline integration: Vendors who can coordinate across mechanical, rotating equipment, and inspection scopes are often more attractive for large, integrated outages.

5. Use ExecGraph to shorten the path to the right people

• Full-org visibility at targeted facilities: ExecGraph maps the complete organizational structure of every major refinery and chemical plant in Texas, including turnaround planners, reliability engineers, maintenance managers, and procurement contacts.
• Decision-chain clarity: The platform shows how decisions move from technical recommendation to financial approval and purchase order, helping vendors focus on the roles that truly influence specification and award.
• Warm-path intelligence: By linking career overlaps across facilities, ExecGraph highlights where your existing relationships can unlock introductions at new Texas refineries.

For any vendor selling into the Texas refining sector, understanding who is responsible for turnaround planning at target accounts and reaching them 12 to 18 months before the expected outage remains the single highest-value activity.
