80% Cost savings: Modern hybrid inspection in the industry
Reducing costs and increasing efficiency - the future of industrial inspection

The challenge in the modern inspection of industrial plants
Industrial plants are under double pressure today: On the one hand, strict safety standards and increasing regulatory requirements demand regular and thorough inspections. On the other hand, rising costs and tight maintenance windows are putting companies under pressure to carry out inspections as quickly and efficiently as possible. Traditional methods are reaching their limits here, as they present time-consuming and costly challenges:
-
Scaffolding and safety measures:
Required for every inspection, cost-intensive and time-consuming. -
Plant downtimes:
Production losses mean direct losses. -
Lack of specialised personnel:
Skilled labour is in demand and expensive. -
Areas that are difficult to access:
This often requires complex and cost-intensive security measures.
The hybrid approach using the example of tank inspection
- Phase 1: Fast drone inspection:
A comprehensive overview of the condition of the system is possible in just a few hours. High-resolution images of critical areas such as weld seams and transitions, supplemented by thermographic analyses, provide early indications of potential damage. Equipped drones even carry out ultrasonic wall thickness measurements, providing precise measurement results even in areas that are difficult to access. The image analysis is available immediately after the flight, enabling quick decisions to be made.
- Phase 2: Targeted detailed inspection (by you):
The drone images are used to carry out further inspections precisely where anomalies are visible. Conventional inspection methods are used here, but only in a minimised area. This saves valuable time and significantly reduces the amount of scaffolding required. This targeted approach significantly shortens the inspection time and increases occupational safety.
- Phase 3: Transfer of the findings:
Once the inspection has been completed, the findings are used to assess other tanks or systems of the same design at the same location. Factors such as year of construction, product history and operating conditions help with the risk-based decision on further measures and enable the development of efficient inspection strategies. This allows future inspection intervals to be optimised.
When the hybrid approach is particularly worthwhile
- Tank farm with several identical tanksDrones offer a quick initial assessment for all tanks or silos. A detailed inspection is only carried out in the event of anomalies, and the findings can be efficiently transferred to identical units, saving time.
- New systems or systems with a good maintenance historyFor systems that were inconspicuous during previous inspections, the drone inspection serves to confirm the expected condition. This minimises scaffolding costs and shortens inspection times.
- Difficult to access system partsHigher parts of the plant or complex pipework that would otherwise require expensive scaffolding or industrial climbers can be inspected quickly and easily using a drone.
Concrete savings potential
Direct cost savings:
- Scaffolding costs: savings of up to 90% thanks to reduced scaffolding assembly.
- No need for cranes or industrial climbers.
- Reduced labour costs due to shorter inspection times.
- Reduction of the inspection time by 60-80%.
Reduced preparation effort:
- No time-consuming scaffolding erection and removal.
- Minimisation of ventilation and safety measures.
- Simplified coordination of the trades involved.
Indirect savings:
- Minimised system downtimes and reduced production losses.
- Faster reporting thanks to digital documentation.
Digital added value and future prospects
Through the use of LiDAR point clouds and the creation of digital 3D documentation, hybrid inspection not only offers short-term cost savings, but also a sustainable basis for future inspection planning. The traceability and comparability of different inspection times enable an optimised maintenance strategy and efficient use of resources.
