External/Internal Boiler Stacks Aerial Inspection Using Drones Project – YNGL/Saudi Aramco

Boiler stacks were critical assets with no inspection done for 14+ years
Internal inspection involved confined spaces, height risk, and long shutdown windows
Manual methods required scaffolding and extended outages lasting months
High safety exposure for inspection teams
Limited visual coverage and inconsistent documentation from past inspections

Deployed latest caged drone for safe internal and external boiler stack inspection
Conducted high-resolution visual inspection of 4 boiler stacks
Enabled access to confined and vertical sections without scaffolding
Rapid aerial data capture with stabilized imagery inside live industrial environments
Digital inspection outputs ready for review, analysis, and archiving

Completed inspection in a few days instead of several months
Eliminated scaffolding, rope access, and confined-space entry risks
Significant reduction in plant downtime and inspection cost
Delivered clear visual evidence for integrity assessment and maintenance planning
Enabled YNGL to assess long-neglected critical assets safely and efficiently
