Drone Pipeline Inspection

Line patrol has been flown for decades — by aeroplane, at a few hundred feet, at speed. A drone trades coverage rate for resolution, which changes what the patrol is for rather than simply making it cheaper.

Resolution a fixed wing cannot give

A manned patrol covers hundreds of miles a day and sees the obvious. A drone at low altitude resolves a hand-dug excavation, a new fence post in the easement and a patch of stressed vegetation over the line.

Encroachment is the real finding

Third-party excavation is the leading cause of serious pipeline incidents. Most of what a right-of-way survey usefully produces is a record of who has been doing what in the easement, dated.

Repeatable, so change is visible

Flown the same way each cycle, the survey becomes a difference rather than a description — new ground disturbance since last time is far easier to spot than ground disturbance in the abstract.

Posting and receiving quotes costs nothing, and SkyLog takes no commission and adds no markup. You pay the pilot you hire, at the price the two of you agree.

What this settles

  • Easement condition: encroachment by structures, fences, vehicles and stored material, third-party excavation, new tracks and unauthorised crossings.
  • Ground conditions over the line — subsidence, washout, exposed pipe at water crossings, slope erosion and bank protection.
  • Above-ground assets: valve sites, pig traps, CP test posts and rectifiers, markers, meter stations and fencing.
  • Whether the maintenance access route is passable, which matters the day you need it.

What it does not

  • Detect gas. Visual patrol finds the consequences of a leak — stressed vegetation, discoloured soil, sheen — and finds them late.
  • Cover a long route in one deployment under standard rules. Line of sight means repositioning every mile or so.
  • Satisfy a regulatory leak detection programme just by being aerial. The method has to satisfy the programme.
  • Avoid landowner access. A pilot repositioning along a route is repeatedly on someone's property.

Commissioning a visual patrol and expecting leak detection from it is the most expensive misunderstanding available in this category. Say up front which you need.

How it works

Three steps, no account needed to start, and nothing to pay at any point in it.

  1. 1

    Describe the job

    The form opens with this page's answers already filled in — service, deliverable, site access. Add the location and anything specific to your site.

  2. 2

    Pilots quote it

    Every pilot whose service area and services match is notified. You get itemised quotes back with their credentials, kit and sample work attached.

  3. 3

    Compare and hire

    Pick on price, proximity or portfolio, and pay the pilot directly. SkyLog takes no cut and adds no markup to what you agree.

Visual line of sight is the governing constraint

A pipeline is long and thin and a standard Part 107 operation requires the aircraft to stay within the pilot's visual line of sight. In practice that means repositioning along the route every mile or so, which turns a long line into a day of driving punctuated by short flights. This is the single biggest determinant of what aerial patrol costs per mile, and it is why beyond-visual-line-of-sight approval matters so much in this sector: with a BVLOS waiver or an approved operation, a single deployment can cover a materially longer stretch. Such approvals exist and utility and pipeline operators hold them, but they are not something to assume a pilot has. If your route is long enough for the arithmetic to matter, ask directly whether they operate BVLOS and under what authorisation, because it changes the price per mile more than anything else on this page.

What the survey covers

The easement itself: encroachment by structures, fences, vehicles and stored material; evidence of third-party excavation, new access tracks, or grading; and unauthorised crossings. Ground conditions over the line — subsidence, washout, exposed pipe at water crossings, erosion on slopes, and the state of any bank protection. Vegetation, both encroaching growth and the stressed or discoloured patches that can indicate a product release below. Above-ground assets: valve sites, pig launchers and receivers, cathodic protection test posts and rectifiers, markers and signage, meter stations and their fencing. And access: whether the maintenance route is passable, which matters the day you need it.

Leak detection is a different survey

Visual patrol finds the consequences of a leak — dead or stressed vegetation, discoloured soil, sheen on standing water — and finds them late. Detecting the gas itself needs a sensor built for it: optical gas imaging for hydrocarbon plumes, or a laser-based methane sensor flown low along the line. These are separate payloads with separate skill requirements, and if the survey is reporting into a regulatory leak detection programme the method has to satisfy that programme, not merely be aerial. Say up front which you need. Commissioning a visual patrol and expecting leak detection from it is the most expensive misunderstanding available in this category.

Specifying it

Give the route length in miles and the diameter and product, because those set both the risk framing and the site rules. Say whether you need the corridor, the above-ground assets, or both. State the cadence — patrol frequency is usually driven by your integrity management programme, and a recurring commitment prices very differently from a one-off. Name the deliverable: a georeferenced image set indexed by milepost is the minimum useful thing, an orthomosaic of the corridor is better for comparison between cycles, and findings need coordinates precise enough to dispatch to. Flag landowner access, since a pilot repositioning along the route is repeatedly on someone's property. And say what the survey reports into, because a document supporting a regulatory programme has requirements a general patrol does not.

Common questions

Can a drone patrol a whole pipeline?

Not in one flight under standard rules — visual line of sight requires repositioning every mile or so. With a BVLOS approval a single deployment covers far more. Ask any pilot whether they hold one; on a long route it is the main cost driver.

Can it detect a leak?

Only with a sensor for it — optical gas imaging or a laser methane detector. A visual patrol finds the after-effects, such as stressed vegetation and discoloured soil, and finds them late. Specify which survey you are buying.

How much does it cost per mile?

It depends almost entirely on whether the operation is within visual line of sight or BVLOS, then on access along the route. Inspection quotes on SkyLog have ranged $100 to about $1,550 with a $300 median across 13 quotes of every type, which is not a per-mile guide — post the route length and cadence for real numbers.

Is it better than manned aerial patrol?

It is different. A fixed wing covers far more ground per day at lower resolution; a drone resolves detail a manned patrol will never see. Several operators use both — manned for routine broad patrol, drones for detailed survey of specific segments and for follow-up.

What about landowner access?

It is a real planning item. A pilot repositioning along a route is repeatedly launching from private land, so easement rights and notification need sorting before the survey rather than at the gate.

Will the survey satisfy our integrity management requirements?

That depends on your programme and your regulator, not on the technology. Establish what the programme requires and specify the survey to it — and if a particular detection method is mandated, say so in the post.
