Drone Cost for Oil Refineries: What Drives It

Drone cost for oil refineries turns on shutdown scope, stack and tank access, flight rules and labor hours. See what drives the lease quote and what it covers.

By Veer Adyani

The short answer

Drone cost for oil refineries depends on how many inspection points each shutdown covers, how high and how confined those points are, how much mapping and flight planning the site needs, and how many units and service visits the lease includes. No single figure applies across the industry, because a crude unit with dense piping and a tank farm with open access carry very different labor loads. The lease quote is set after a free site assessment that counts the flare, stack and tank-top work now done on scaffolds or in confined spaces.

Key takeaways

  • The lease quote depends on the inspection points in each shutdown, not on refinery size alone.
  • Flare stacks, tank tops and confined spaces are where a drone saves the most crew time.
  • Mapping, flight authorizations, training and service are the costs people most often miss.
  • Leasing through financing spreads the cost into a fixed lease payment set after a site assessment.
  • Get a lease quote after a free site assessment that counts shutdown points and access routes.

What the drone cost for oil refineries depends on

Drone cost for oil refineries depends on the work the aircraft must do in each shutdown and on how hard that work is to reach. A site with a few tall stacks and open tank tops needs a separate plan from one with dense process units, long pipe racks and many enclosed vessels.

Four things set the base. The count of inspection points in each shutdown comes first. Access comes second, meaning height, enclosed space and whether a point can be reached without a scaffold. Site rules and flight authorization come third, and the number of aircraft and service visits needed to finish the list on time comes fourth.

No price appears on this page because none fits every site. The lease quote is written after we see the site, and it reflects your list, your shutdown calendar and the level of support you want.

How many inspection points does a shutdown include?

According to the U.S. Energy Information Administration, there were 130 operable petroleum refineries in the United States as of January 1, 2026. That count shows how many sites could use the approach, but it does not show how many inspection points any one refinery carries. Each site has its own mix of process units, flare systems, storage tanks and utility areas, and that mix is what a quote is built on.

In a shutdown, the points that matter most tend to cluster. Flare and vent stacks are tall and sit close to active process areas. Tank tops are spread across the tank farm, often reached from steel platforms. Pipe racks and furnace stacks carry runs of piping and instruments that need close looks. Each cluster brings its own access rules and its own hours.

Count the points in each cluster first. A list with most points on two stacks is a lighter job than the same count spread across a tank farm, and the quote follows that shape.

Why do flare, stack and tank work cost more?

Flare and stack work is costly because access is the cost. A tall stack usually calls for a crane, a scaffold or rope access, and a crew with the right certifications. Each of these adds planning, permits and waiting time before anyone can inspect a flange or a weld.

Injury rates give context, but they do not measure exposure. According to the API Workplace Safety Report 2024, the nonfatal injury and illness rate for refinery workers was 0.4 per 100 full-time workers in 2024. That average covers the whole workforce and all hours, so it does not show how much time a shutdown crew spends at height or in confined spaces.

Tank tops add cost through repetition. Each tank needs its own access plan, and a tank farm multiplies the setup work even when each individual look is short. Confined spaces add entry permits, gas testing and attendants, and those steps repeat for every entry the crew makes.

Which hidden costs do people miss?

The first hidden cost is mapping and flight planning. Before the first flight, the site needs a model of the stack or tank farm, a plan for the buffer around active areas, and a list of points tied to the shutdown schedule. This work happens before any aircraft flies, and it has to be redone whenever the scope changes.

Authorization is the second. AFPM guidance states that operations outside Part 107, such as flights above 400 feet, need an FAA Certificate of Waiver or Authorization, and that the lead operator of the unit must be notified of drone operations. Those steps need lead time, so they belong in the plan before the shutdown starts.

Software, maintenance, insurance and training finish the list. Data processing and reporting can be a separate line from the aircraft itself. Maintenance and spares keep the aircraft ready through the window, insurance covers the flights, and trained operators and reviewers keep findings moving to the inspectors who sign off. The lease quote states which of these items are covered, so compare quotes on that written scope.

  • Mapping and flight planning for each stack and tank farm
  • FAA authorizations and operator notification
  • Data processing and reporting software
  • Maintenance, spares and repairs during the window
  • Insurance and liability coverage for the flights
  • Training for operators and data reviewers

How many labor hours does a drone take over?

The clearest hour figures come from vendor case studies, so treat them as estimates to test, not audited results. One case study, reported by Unmanned Systems Technology, describes a 200-foot in-service flare stack inspected in 2 hours. The same case puts typical crane and technician work for that job at about 3 days.

Scaffold-based flare work follows a longer sequence. A vendor case study describes shutdown and cooling first, then scaffold erection over 3 to 5 days, then rope-access technicians on the stack. Each step is a schedule risk, and a delay in one can push the next into a later window.

Tank tops follow the same pattern. A vendor case study on a Gulf Coast refinery reports that scaffolding around one tank takes 3 to 5 days. An aerial pass removes that setup for visual checks, although repairs still need crews on the tank.

How does leasing through financing work?

We lease the drone through financing, so the site does not have to fund the aircraft up front. The lease carries a fixed lease payment over a set term, and the quote shows that payment next to the scope it covers. That structure keeps the shutdown budget free for the work itself.

We are a US commercial robot integrator. We pick the aircraft for the site, lease it through financing, deploy and integrate it with your planning and reporting, train the staff who fly and review the data, and service it nationwide. One team handles the lease, the setup and the service calls, so the site has one number to call.

A quote lists what is in scope: the aircraft, mapping and integration, training, maintenance, and how a grounded aircraft is replaced during a shutdown. It is written after a free site assessment, so the number reflects your stacks, tanks and calendar rather than a generic sheet.

Where does a drone fly at a refinery?

A refinery drone works in a small set of zones, not across a wide floor. The job is to reach the points that need a closer look during a shutdown and to leave the rest of the site alone. The site assessment defines the zones, and the operations team decides which areas stay out of the flight plan.

The setting is large, even though the flight plan is narrow. According to the Bureau of Labor Statistics Occupational Employment and Wage Statistics page for petroleum and coal products manufacturing, there were about 108,320 total employees in NAICS 324000. The page does not state its reference year, so read that figure as a sector headcount rather than a count for any one site.

Hours worked tell a similar story. According to BLS productivity data published through FRED, the hours worked index for NAICS 3241, petroleum refineries, was 239.948 in 2025 and 233.349 in 2024, on a 2017 base of 100. Coverage at a refinery is measured in points inspected per shutdown, not in floor area, so the site assessment counts points on each stack and tank.

What can a drone not do at a refinery?

A drone does not replace hands-on repair, contact inspection that needs a crew, or entry into a vessel that must be gas-tested first. It gives the inspection team a closer look without a scaffold and without an entry. A qualified reviewer still decides which findings need a crew and which can wait.

The airspace and the site set limits too. Flights outside Part 107 need authorization, and the unit's lead operator needs notice. Active flaring, weather and site safety rules can set the flight window, so some points may still need a crew on the day, even with the aircraft on site.

How do I get a quote after a site assessment?

Start with a list of what the next shutdown must inspect: stacks, flare systems, tank tops, pipe racks and any enclosed spaces the crew would otherwise enter. For each point, note the access method used today, whether scaffold, crane, rope access or entry. That list is the main input to a drone cost for oil refineries quote, and a clear list shortens the assessment.

The free site assessment comes next. We map the target points, review the authorization path, confirm the shutdown dates and agree on which tasks the aircraft will handle. The lease quote follows, with the fixed lease payment, the term, the written scope and the service levels.

If you want to test before committing to the whole list, start with one stack or one tank farm. A single pilot area shows how your crew and the aircraft plan around the shutdown before the program grows to cover the rest of the refinery.

Frequently asked questions

This page does not give a figure, because cost depends on the inspection points, access, authorizations and service scope at each site. A lease quote is written after a free site assessment and shows the fixed lease payment with the scope it covers. Ask for the written scope so you can compare quotes on the same basis.
