A 90 kV line at Matiti: 511 photos and 106 anomalies on five wooden supports
On 1 June 2026, in the late afternoon, Omexom THT Antilles-Guyane asked us for a drone inspection of a 90 kV line in Macouria, between supports 50 and 60. A fault was preventing the line from being re-energised, and they needed to see what had happened: a cable on the ground, a snake on a conductor, a pylon down. The quote was approved within the hour, with a meeting point in Macouria the next day between 6.30 and 7 am.
A fault check the next morning
On 2 June our team photographed supports 50 to 60, then supports 66 and 94. Two defects were spotted on the cables of the 94–95 span: their position was recorded and delivered in KML and GeoJSON, with an image showing their distance from the support and the photos sorted by support. The results went out in the late afternoon, less than twenty-five hours after the request.
Five wooden supports, on 3 June
During the fault check, Omexom gave us a second job on the same line: the assessment of five wooden-pole supports at Matiti, between supports 43 and 47, namely two pylons and three portal frames. The mission was set for the following day. Each support was photographed in detail according to the client’s specification: 511 photos, each with its GPS position and the heading of the shot.
106 anomalies, rated on four levels
The photos were loaded into the Sentinel Cloud pylon inspection module, where each anomaly is boxed on the image, typed and rated on four severity levels: low, medium, high, critical. The result: 106 anomalies, all open at delivery. By type, 30 are corrosion, 30 bird nesting, 14 structural cracks and 5 loose or missing bolts; the other 26 are mostly termites in the wood. By severity: 7 low, 97 medium, 2 high and none critical. The two high-severity anomalies are corrosion on the access portal and a structural crack on portal 2.
- Access portal: 22 anomalies
- Portal 2: 18 anomalies
- Portal 3: 23 anomalies
- Pylon 45: 19 anomalies
- Pylon 46: 24 anomalies
What was delivered
On 5 June Omexom received all the photos, the annotated photos, a 109-page PDF inspection report with one sheet per anomaly (photo, type, severity, GPS position, orientation) and the Excel table of defects. Its teams were also given access to the platform, where each anomaly can be closed, with a date and a comment, once it has been dealt with.
The same day in Guadeloupe
Also on 2 June, our partner Antilles Drone was photographing pylons 36 to 38 of the 63 kV Bouillante – Sainte-Rose line for the same client, inside the Guadeloupe national park: pylon 37 was fully covered that day, and pylon 36 was completed on 15 July.
