Durban Silo Array

Ending 2023 on a high note, Delta Scan conducted the phase 1 baseline visual inspection by digitising a Durban Silo Array in KwaZulu Natal.

Delta Scan took on the task of investigating the state of a Durban silo array through an internal and external inspection. The investigation covered a total of 35 silos and 16 inter-bins. The largest silo measured 60m in height and 10m in diameter. We captured, digitised, and inspected over 17,500 square meters of external façades and 17,500 square meters of internal façades.

Three teams dispatched: one for photogrammetry, one for thermal data capture, and one utilizing the Elios 3 for internal videography and SLAM LiDAR data capture. The external team completed data capture within 2 days. Internally, data capture spanned 5 days, coordinated closely with the end users’ planning team. This ensured minimal disruption to work activities.

Following data transfer to HQ, the team initiated digital twin creation and inspection. Leveraging our Hybrid AI approach, we generated highly potent façade maps. These served as guides for defect identification and quantification.

We correlated and matched external defects with internal defects. This leveraged the external data. Visuals alone couldn’t achieve this. Yet, our internal drones equipped with LiDAR capabilities enabled us to showcase observed defects on video. As well as pinpoint their precise locations on the LiDAR map. This information was then translated into the external 3D digital twin. This highlighted Delta Scan’s advanced position in inspection workflows and the integration of various technologies. Our approach guaranteed that our customers receive the most comprehensive and powerful reports available.
