Overview
Osprey Inspection carried out a confined-space drone inspection of an internal heater ventilation pipe — diameter 600–800 mm, total length 30–40 metres. The survey documented the internal duct surface without personnel entry, eliminating confined-space-entry risk and the need for a service shutdown or external scaffold access. A collision-tolerant inspection drone flew the full run under its own lighting, capturing the duct wall, joints and burner-end residue in a single continuous pass — turning what would normally be a permit-heavy entry job into a short remote survey.
Scope
- Internal duct surface — corrosion, deposit build-up, coating breakdown and structural condition
- Joint and seam condition between duct sections
- Burner-end soot and combustion-residue distribution
- Debris and obstruction build-up that could affect airflow
- Confirmation of duct geometry and continuity along the full 30–40 m run
Deliverables
Annotated visual inspection report with timestamped imagery, defect register with severity classification, and prioritised maintenance recommendations. Findings tied to position along the pipeline run.
