Drone-Based Monitoring of Energy Infrastructure Sites

Chelpiper 75 is a drone enabling panoramic and vertical still and video aerial photography and other similar functions. Its modular design allows to quickly replace various drone payloads and modify the onboard equipment configurations.

Chelpiper 75 drone's technical characteristics make it a highly efficient unmanned system for protection of oil and gas pipelines.

With air range of at least 360 km, operating altitude 50 ÷ 500 m and flying time of more than 4 hours, the drone is stable and docile enough to be used in challenging weather conditions. The pulling propeller design perfectly suits the intended application and ensures personnel safety.

The extra onboard volume inside the wings allows the drone to carry a broad range of instrumentation. The drone's onboard instrumentation and Automatic Control System enable video and photo data recording while registering multiple service parameters (coordinates, altitude, frame number, etc.), which greatly facilitates post-processing and, most importantly, automates the stitching of frames and helps determine target coordinates. The drone carries photo and video cameras, a thermal imager and a gyrostabilized television camera.

Complex analysis of data streamed by the drone allows to:

  1. Monitor oil spills
  2. Locate illegal taps 
  3. Locate pipeline sections laid at non-standard depths
  4. Monitor new objects within the protected zone 
  5. Monitor and identify moving objects within the protected zone, even during the night
  6. Quickly receive video and photo data from hard to reach locations 
  7. Evaluate forest invasion to predict deforestation needs along the pipeline
  8. Evaluate the speed and quality of repair and construction operations
  9. Evaluate pipeline condition at ground-to-water transitions 
  10. Perform large area still and video photography 
  11. Create photomaps
  12. Perform multiband photography 
  13. Perform industrial and environmental monitoring 
  14. Perform land inventory and status assessment work 
  15. Perform cadastral work
