Why we stopped sending people into tanks

Confined-space entry has been the default for tank inspection for decades. It shouldn't be. Here's the case for retiring it.

For most of the industry's history, inspecting a storage tank meant taking it offline, draining it, ventilating it, and sending a person into a confined space. We think that model is overdue for retirement.

The hidden cost of an entry

Every confined-space entry carries risk that no permit fully removes. It also carries cost: lost throughput, ventilation, standby rescue teams, and days of schedule.

  • Atmospheric hazards that require continuous monitoring
  • Lost product throughput during the outage
  • Standby rescue and permitting overhead

A robot-first default

When a certified robot can do the same work while the tank stays in service, the entry stops being necessary and the data comes back better, not worse.
