How the ASIO Drone Enhances Safety and Efficiency in Spillway Tunnel Inspection

The customer, Group E, required a meticulous inspection of the tunnel’s concrete structure and potential blockages without human entry. The inspection scenario undertaken at Rossens Dam in Switzerland, pertaining to a high-risk confined space – the spillway tunnel.

‍

The infrastructure posed significant challenges due to it is over 8-meter diameter, presenting a high level of difficulty. The objective was to optimise inspection speed and cost-effectiveness, focusing on the importance of efficiency and safety.

The inspection was successfully completed within a single day, highlighting the efficiency and expertise required to fulfill the customer’s specific requirements and ensure the integrity of the spillway tunnel.

RESULTS

‍

Using the ASIO drone, Groupe E completed a visual inspection of the spillway tunnel within 24 minutes, achieving a thorough assessment of the concrete walls and identifying potential blockages.

This inspection was significantly faster and cost-effective compared to traditional methods, reducing inspection time from several days.

How Flybotix Achieved This Result:

The ASIO drone is equipped with advanced software, navigated the confined space efficiently, capturing high-resolution imagery of the tunnel. The drone’s agility and maneuverability allowed it to cover the entire surface, providing a detailed visual inspection without human intervention.

‍

Cost Savings during Inspection:

By utilising the ASIO drone, the need for expensive scaffolding or rope access, costing up to 40,000 CHF and 10,000 CHF respectively, was eliminated. Additionally, there was no requirement to lower the reservoir’s water level, saving an estimated 280,000 CHF and preventing immeasurable environmental water loss.

8-meter diameter ｜ 24 min ｜ $280,000 saved per inspection

BENEFITS

1. Time Efficiency: The ASIO drone completed the inspection in a fraction of the time it would take using conventional methods, minimising downtime for the spillway’s functionality.
2. Cost Savings: Significant cost savings were achieved by eliminating the need for costly infrastructure and water level adjustments.
3. Safety: By keeping humans out of the confined space, the risk to personnel was eliminated, ensuring a safer inspection process.
4. Environmental Impact: The ASIO drone reduced water waste and minimised the environmental impact associated with lowering the reservoir’s water level.
