Case Study: Utilising Confined Space Drone Technology for Waste Gas Duct Inspection
Project Overview: In the heart of Wrexham, North Wales, DJM Aerial Solutions undertook a challenging confined space project for a prominent timber product manufacturer. The task involved inspecting several waste gas ducts reaching heights of 30 meters and extending horizontally for an additional 30 meters. These ducts housed critical process dampers, crucial components for regulating gas flow. Concerns arose regarding the integrity of these ducts, suspected to be severely corroded, posing significant risks for manned inspection.
Client Concerns: The client expressed apprehension regarding the operational efficiency of the process dampers. They suspected a buildup of product hindering the dampers’ closure, potentially leading to gas leakage into the atmosphere. Traditional inspection methods were deemed perilous and impractical due to the precarious condition of the ducts, necessitating innovative solutions to mitigate risks and address operational concerns effectively.
Challenges:
- Safety Risks: Manned inspection posed life-threatening risks due to the corroded state and structural integrity of the ducts.
- Operational Efficiency: Uncertainty regarding damper operation and potential product buildup necessitated thorough inspection for accurate assessment.
- Time and Cost Constraints: Dismantling the ducts for manual inspection would incur extensive downtime and financial losses for the client.
Solution: Employing advanced confined space drone technology, DJM Aerial Solutions proposed a non-intrusive inspection approach to assess the condition and functionality of the waste gas ducts and process dampers. The utilization of Elios 2, renowned for its maneuverability and confined space capabilities, proved instrumental in overcoming the project’s challenges.
Execution:
- Risk Assessment: Prior to deployment, a comprehensive risk assessment was conducted to identify potential hazards and establish safety protocols.
- Drone Deployment: The Elios 2 drone was deployed to navigate the confined space within the ducts, ascending to the towering heights and traversing the horizontal sections with precision.
- Visual Inspection: High-resolution imaging facilitated detailed visual inspection of the ducts, enabling the identification of corrosion, structural defects, and any obstructions impeding damper operation.
- Operational Analysis: The drone’s agile maneuverability allowed for close proximity inspection of the process dampers, assessing their operational efficiency and confirming suspicions of product buildup.
- Data Analysis: Collected data was meticulously analyzed to generate comprehensive reports detailing the condition of the ducts, integrity of the dampers, and recommendations for remedial actions.
Results:
- Risk Mitigation: By eliminating the need for manned inspection, the project significantly mitigated safety risks associated with working in hazardous environments.
- Operational Insights: The inspection provided valuable insights into the condition and functionality of the process dampers, empowering the client to address operational inefficiencies promptly.
- Cost Savings: The non-intrusive inspection approach averted the need for costly dismantling and scaffolding, saving the client substantial financial resources and minimizing downtime.
Conclusion:
Through the strategic utilization of confined space drone technology, DJM Aerial Solutions successfully addressed the inspection challenges posed by the waste gas ducts for the timber product manufacturer in Wrexham. The project not only ensured the safety of personnel but also provided critical insights into operational efficiency, ultimately saving the client valuable time and financial resources. As pioneers in aerial inspection solutions, DJM Aerial Solutions continues to demonstrate its commitment to innovative engineering practices and delivering exceptional results for clients across diverse industries.
