Mine Storage Silos

Delta Scan was contracted by one of our clients, a platinum producer in Mpumalanga, South Africa, to conduct an annual baseline inspection on 2 mine storage silos in October 2023. Silo inspections can be tricky and time consuming. This is depending on size and method of inspection, hence our customers continued the use of our services. Operations delays are kept to an absolute minimum insuring minimal loss to the customers productivity.

The inspection conducted was an external and internal inspection using Delta Scans drone data capture workflows. However, the key to this project was taking the reporting to the next level. Our external façade maps have become a statement point in our report delivery. Often being the most valuable piece of information assembled after inspections, and for some time replicating that for internal façade maps had proven a challenge.

Delta Scans experienced data capture team implemented an internal data capture workflow which has now allowed our master technicians to recreate the façade maps for the internal surface of the silo. This gives the client a complete digital twin and a complete defect road map.

In a single mobilisation, and in one day on site, data capture was complete. This depth in information would take conventional means at least 2-3 weeks to capture. While the reporting produced from conventional means would take another 2-3 weeks. As well as it would fall far short from what the client received just 6 days after leaving site. Full internal and external digital twins, annotated with defects, LiDAR point cloud for verification of geometry, internal & external façade maps, various defects identified and quantified, and a full baseline report of findings with recommendations and remedials.

 

Project Details:
  • Internal Inspection flight time per Silo: 10 minutes
  • More time spent driving to site then capturing on site.
  • Internal & external façade maps
