Entry into confined spaces is one of the highest-risk activities in industrial inspection. The permit-to-work burden, the standby and rescue requirements, the atmospheric monitoring, and the physiological limitations of personnel in confined environments all compound to make internal inspection of vessels, tanks, columns, and pipelines both expensive and hazardous.
Confined Space Drone Inspection
Capability
Internal Inspection Without Entry
Collision-tolerant inspection drones
equipped with omnidirectional lighting and high-resolution cameras navigate the
internal geometry of pressure vessels, storage tanks, column shells, and
large-diameter pipework — capturing detailed visual evidence of internal
corrosion, coating condition, lining integrity, weld condition, and structural
damage without personnel entry.
Elimination of Confined Space Risk for Preliminary
Assessment
Drone survey provides a rapid preliminary assessment that determines
whether entry is actually necessary — and if so, precisely where personnel
should focus their attention. This changes the risk profile of the entire
inspection campaign: human entry is directed only to the specific areas where
the drone survey has identified conditions requiring direct assessment.
Conditions Unsuitable for Entry
Where vessels cannot be fully gas-freed, where temperatures remain
elevated post-shutdown, or where structural instability makes entry
inadvisable, drone inspection provides the only mechanism for internal visual
assessment. Our platforms are rated for operation in environments that preclude
safe human entry.
Reports include internally annotated visual records with defect location
and classification (corrosion, coating failure, structural anomaly, mechanical
damage), and recommended action. All footage and still imagery is provided as a
referenced inspection record with asset location mapping within the inspected
volume.
