Robotic platform for remote in-service floor inspection of hazardous petrochemical storage tanks
NEPA is a compact, intrinsically safe robotic inspection system built for above-ground storage tanks.
It enables remote tank-floor inspection without draining the tank, purging vapours, or sending personnel into confined and hazardous spaces.
Designed to operate fully submerged in oil and within explosive atmospheres, NEPA enters through standard tank manways and navigates across the tank floor to access areas that are difficult, dangerous, or costly to inspect manually.
Using an integrated ultrasonic testing probe, NEPA captures wall-thickness and corrosion data, combined with location information for accurate post-processing, reporting, and asset integrity assessment.
The result is a safer, faster, and more cost-effective approach to tank integrity management, reducing downtime, improving inspection quality, and supporting better maintenance decisions.
Built for Harsh Tank Environments
NEPA is engineered for the storage tank sector, where safety, reliability, and access are critical.
Its rugged, portable design allows rapid mobilisation by a small team, reducing setup time and maximising the time spent on inspection and maintenance.
