Drone Inspection vs. Conventional Methods

Conventional inspection methods are reaching their limits. Scaffolding erection takes weeks, human entry into confined spaces is life-threatening, rope access is expensive and time-consuming. During active operations these methods are often not feasible at all – and for large plant parks with dozens of tanks or boilers, costs explode.

The solution: drone inspection. The Flyability ELIOS 3 inspects confined, dark industrial plants GPS-independently and collision-safely – tanks, boilers, reactors, shafts, chimneys. 4K camera, LiDAR 3D survey and optional thermography deliver in hours data that classically required weeks. The DJI M30T complements this for exterior inspections of pipe bridges, facades and rooftops with 200x zoom and radiometric thermography.

The 8 Key Benefits of Drone Inspection

Up to 80% Time SavingsInstead of weeks of preparation with scaffolding erection, the inspection takes just a few hours. Fast execution, fast results.
Maximum SafetyNo human entry into confined spaces, no rope access, no risk for your personnel. The drone takes the risk.
Minimal DowntimeInspections often possible during reduced operation or even full operation. No days-long production shutdowns.
Cost EfficiencyUp to 80% cheaper than conventional methods. No scaffolding, no complex preparation, no large team required.
Complete Documentation4K video, high-resolution photos, LiDAR 3D models and thermography. Seamless documentation for your records.
Access to Hard-to-Reach AreasThe ELIOS 3 reaches areas that are inaccessible or too dangerous for humans. Compact enough for openings from 50 × 50 cm (standard manholes).
Repeatable InspectionsThanks to LiDAR navigation, exactly the same areas can be documented in follow-up inspections. Perfect for damage progression monitoring.
DGUV-CompliantNo confined space entry (Befahrung) under DGUV required. No human entry = no complex safety measures and rescue chains.

Time Savings in Detail

Conventional inspection with scaffolding: 5–8 weeks

The biggest time drain is not the actual inspection – but the lead-up: scaffolding procurement, DGUV confined space concept, permits, safety guards, PPE procurement, coordination with the operator and possibly regulatory inspectors. Then the scaffolding itself goes up, the plant is shut down. Only then does the actual inspection begin.

  1. Planning & Approval (2–4 weeks): Commission scaffolding, prepare DGUV confined space concept, permits, safety guards, PPE. Coordinate shutdown date, possibly book ZÜS appointment (waiting queue up to 6 weeks).
  2. Scaffolding erection & dismantling (5–10 days): 3–7 days erection, 2–3 days dismantling. Complete production shutdown. For tanks: empty, clean, inertise – before and after inspection. Costs: €15,000–60,000 for scaffolding and confined space logistics alone.
  3. Inspection & documentation (2–5 days): Manual visual inspection. Results subjective, hard to reproduce, no 3D data. Spatial reference for comparison with prior-year findings is often missing.
Drone Inspection: Hours Instead of WeeksLead time 1–2 days (briefing, approval, travel). On-site inspection 4–16 hours depending on plant. Digital report within 3–5 working days. Minimal or no production shutdown.
Better Data Quality4K video, LiDAR 3D point clouds (centimetre-accurate survey), thermography – objective, repeatable documentation instead of subjective visual inspection. Exactly the same spot documentable at next inspection.
No ScaffoldingNo erection, no dismantling, zero scaffolding costs. If findings require follow-up: only spot scaffolding or local rope access exactly where it is actually needed.

70–80% time savings with simultaneously higher documentation quality through 4K, LiDAR and thermography.

Time Comparison by Asset Type: Real Numbers

What this means in practice – by asset type. These comparison values are based on our project experience since 2017 and reflect typical values – not marketing promises:

Asset Type Conventional Drone Time Savings
Tank (1,000 m⊃) 3–5 days (scaffolding + entry) 4–8 hours approx. 80%
Boiler (large steam generator) 2–4 weeks (cool-down + scaffolding) 1–2 days approx. 75%
Chimney (50 m) 5–10 days (climbers + rope team) 4–6 hours approx. 85%
Silo (500 m⊃) 2–3 days (scaffolding + entry) 2–4 hours approx. 75%
High-bay warehouse (5,000 m⊃) 2–4 days (elevated platform + crane) 4–8 hours approx. 70%
Pipe bridge (100 m) 3–7 days (scaffolding or climbers) 4–8 hours (external) + 1 day approx. 65%

Cost example – tank inspection (1,000 m⊃): Scaffolding and conventional confined space entry typically cost €15,000–40,000 – plus production downtime. Drone inspection comes in at €2,500–6,000. Production downtime – often the biggest cost driver – is largely eliminated or reduced to a few hours.

For a single medium-sized tank (1,000 m⊃) the typical saving is €12,000–35,000 compared to conventional scaffolding. Including production downtime, this figure multiplies.

Typical Use Cases

Power Plants & Energy GenerationBoilers, flue gas ducts, cooling towers, chimneys – once at ambient temperature, without scaffolding. Typical saving vs. conventional boiler mounting: 75–80% time, €15,000–50,000 scaffolding costs.
Chemical & Petrochemical PlantsReactors, columns, vessels, pressure vessels per BetrSichV – also in near-ATEX areas (ELIOS 3 not ATEX-certified, but suitable for gas-free confined space inspection). Time savings: 65–80%.
Tanks & Vessels (TRbF / API 653)Steel tanks, concrete tanks, storage tanks, sprinkler tanks – complete internal visual inspection of walls, floor, welds. No DGUV confined space entry required.
High-Bay Warehouses & LogisticsRack inspection per DIN EN 15635 – without operational interruption, without elevated platform, without crane. Complete racking aisle (10 m × 30 m) in approximately 1 hour.
Chimneys & StacksInterior inspection of flue gas ducts and linings without climbers, without scaffolding. 50 m chimney in 4–6 hours instead of 5–10 days. Thermography for heat losses and masonry damage.
Silos & Grain StoresCement, clinker, grain silos – complete inner wall inspection, crack detection, anchor check. After DGUV 113-004 no human entry required where drone inspection delivers equivalent results. 500 m⊃ silo: 2–4 hours instead of 2–3 days.

From the Expert

“The biggest time saving comes not from the flying itself, but from eliminating scaffolding erection and the complex DGUV confined space entry procedures. What used to take weeks, we now complete with the ELIOS 3 in hours – with better documentation.”

Frequently Asked Questions about Drone Inspection

Is 80% time savings a realistic figure?

Yes – for tank and boiler inspections where the main effort was previously scaffolding erection, this figure is realistic and supported by our project data since 2017. The saving is larger when the plant would otherwise have required a long shutdown. For simpler assets (short chimneys, small silos) the percentage saving may be somewhat lower. We always show you the specific comparison for your plant.

Is drone inspection also possible during ongoing operation?

For exterior inspections (pipe bridges, facades, chimneys exterior) often yes – without any production interruption. For interior inspections (tanks, boilers, silos) the plant must be shut down, cooled and depressurised. But: the shutdown duration is dramatically shorter than with conventional methods, because there is no scaffolding to erect.

What data quality does the drone deliver compared to manual inspection?

4K video from close proximity often shows more detail than the human eye in dark, cramped conditions. LiDAR delivers centimetre-accurate 3D geometry – quantitatively measurable damage extent that a manual inspector can only estimate. Thermography detects hidden hotspots. The combination is typically superior to manual inspection for visual findings – only contact testing (UT wall thickness) requires physical contact or specialist NDT personnel.

How much does a drone inspection cost?

This depends on the asset type, size and inspection scope. As a rough guide: a tank inspection (1,000 m⊃) costs approximately €2,500–6,000 including travel and report. That compares with €15,000–40,000 for a conventional confined space entry with scaffolding. Contact us for a specific quote for your plant.

Does the inspection result meet BetrSichV requirements?

Our inspection documentation is prepared according to the requirements of BetrSichV and DGUV. The findings report, 4K videos and LiDAR data serve as the information basis for the licensed inspector (ZÜS/TÜV). Whether drone inspection replaces the formal inspection appointment depends on the specific inspection obligation – we clarify this together with you and the inspection organisation in advance.
