Overview
Osprey Inspection ran a confined-space drone inspection of an internal heater ventilation pipe: 600–800 mm diameter, 30–40 metres of run. We documented the duct surface without putting anyone inside it, so there was no confined-space-entry risk, no service shutdown and no need for external scaffold access. A collision-tolerant inspection drone flew the full length under its own lighting, capturing the duct wall, joints and burner-end residue in one continuous pass. What's usually a permit-heavy entry job turned 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.
