Confined environment inspections

Confined environment video inspection service

The activity is carried out using an A.P.R. device, commonly known as a drone, designed specifically for difficult-to-access environments, capable of performing video in the visible and infrared. The drone we use, which is the state of the art currently available, is also capable of generating a digital map of the route taken, which can then be inserted within a larger digital map, for example that of a facility or city.

Inspections can be conducted, without particular problems, in environments with total absence of light, even very dusty and with the presence of water. The use of drones for the inspection of confined spaces is an increasingly common methodology in the industrial and civil fields, because it ensures both a reduction in the time of execution of the activity and therefore costs and greater safety for operators.

Video inspections in the industrial field
The most common applications in the industrial field involve video inspections, of tanks, smokestacks, chimneys, boilers, heat exchangers, tube bundles, etc.

Video inspections in the civil sector
The most common applications in the civil sector involve video inspections, of condemned buildings and structures, sewers, dams, penstocks, tunnels, etc.

The use of the drone for the types of environments indicated above, and more generally for all those environments with difficult access, makes it possible to greatly cut down the time required to perform the activity. Its use allows the operator to perform the inspection from a remote location, in total safety. Thus avoiding the need to build expensive infrastructure in order to reach the inspection point and break into confined, potentially dangerous environments.

3D mapping and reporting
The service offered by Aesse Misure is not limited to video inspection, but with the help of state-of-the-art systems, it can also provide a 3D digital map of the route taken by the drone. Thanks to this digital map, it is easier to identify, within the path, the points on which anomalies have been identified. In addition, the map can be georeferenced and possibly inserted within a larger digital map, which can represent, for example, a plant or a city.

Possible problems that can be highlighted by visual inspection (camera in the visible):

  • Slots
  • Cracks
  • Damaged welds
  • Vaiolature
  • Accumulation of material
  • Corrosion
  • Breakdowns
  • Infiltration

Possible problems that can be highlighted by visual inspection with a camera in the infrared:

  • Gas or liquid leaks, infrared sees temperature change
  • Overloads and overheating as infrared detects hot spots within electrical systems or equipment
  • Thermal insulation problems in walls, pipes
  • Moisture or water infiltration that thanks to infrared but also the visual chamber you can see mold and corrosion.

Benefits gained in using an A.P.R. device for confined space inspection activities

  • Reduced inspection time
  • Reducing the risk to operators
  • Cost reduction
