UAV technology and NDT


Good afternoon.
UAV technologies are becoming more common in the technological offers of companies that provide industrial services.
I need to know if there is any accepted general regulation, standards, codes, etc., for the application of Visual Inspections, Thermography and even Leak Testing to various industrial facilities (refineries, chemical plants, etc.) using UAV technology or if on the contrary there are only general guidelines developed by the companies themselves.
Thanks in advance.

UAV you can see the visual very clearly correctly by unmanned aerial vehicle.

This is a visual aid to do visual testing to do visual of stacks where you cannot go.


The company recommends what you can do to control the problem or eliminate if possible.

you can combine infrared camera if you want to do so, with remote operation systems.

Thank you very much for your comment Mr Kumar.
Maybe I do not formulate my question correctly, I will try to redo it.

The most updated codes in the techniques of Visual Inspection and / or Thermography make some mention to the use of UAV technologies? Is there any criterion or methodology or minimum conditions that regulate the use of these technologies in industrial facilities?

Thanks in advance

Roberto

Robert,

Right now I don't know if there are any national or international bodies such as ASME, ASTM, ISO that have developed standards or codes which specifically address the use of UAV, ROV, or ROUV (remotely operated underwater vehicles).

ASME Section V (Nondestructive Examination) addresses remote visual by stating:
T-953 REMOTE VISUAL EXAMINATION
In some cases, remote visual examination may have to be substituted for direct examination. Remote visual examination may use visual aids such as mirrors, telescopes, borescopes, fiber optics, cameras, or other suitable instruments. Such systems shall have a resolution capability at least equivalent to that obtainable by direct visual observation.

ASME Section XI (Inservice Inspection of Nuclear Power Plant Components) addresses "remote" visual by stating in IWA-2111:
(g) Remote visual examination may be substituted for direct examination. The remote examination procedure shall be demonstrated capable of resolving characters as specified in Table IWA-2211-1. Additionally, the remote examination system shall have the capability of distinguishing and differentiating between the colors applicable to the component examination being conducted.
IWA-2211-1 has this:

Minimum Illumination, fc (lux)
VT‐1 50 (550)
VT‐3 50 (550)
Maximum Direct Examination Distance, ft (mm)
2 (600)
n/a
Maximum Height for Procedure Demonstration Characters, in. (mm)
0.044 (1.1)
0.105 (2.7)

I would say the most conservative thing is to to have a physical demonstration where the smallest, coolest, hottest, etc. item you need to find is at the maximum distance that your vehicle would be located.

Just to fly, every jurisdiction will have its own rules. For commercial pilots a radio licence plus a drone pilot licence for the weight class (<1kg, <25kg, etc.) of the drone and maybe a special flight operations certificate. I am posting from Canada, every country is different. Preparatory classes for government exams are called Ground School here. Instruction for the specific model you want to fly should come from the manufacturer or maybe the rental supplier.

After that, you still need certification in whichever NDT or SNT method you will be using. Thermography is typically a weeklong course. Some NDT methods have codes about maximum distance from your eyes to the indication.

Lastly, you need special permission from the site owner listed on you work permit. Also, remember that most drones are not Class1Div1 limiting there use in confined space.

Hi all! Many thanks to the specialists who commented on this topic. I think I have a little better idea on the subject.
Thank you.
