The SR-3

Every time an aboveground storage tank undergoes conventional inspection, hundreds to thousands of kilograms of hydrocarbon vapor are released into the atmosphere. These emissions are not an accident —they are an unavoidable by product of the manual inspection process, which demands that operators drain, vent, and clean each tank before a human inspector can enter.

Square Robot eliminates this emissions event entirely. By deploying autonomous robotic inspection technology that operates inside tanks while they remain filled and in service, Square Robot removes the need for pumpout, venting, and confined-space entry — and with it, the associated greenhouse gas releases.

This white paper explains the mechanism by which conventional inspections generate emissions, the model used toquantify those emissions, and the documented impact of Square Robot’s approach. It is intended for ESGand sustainability teams evaluating storage tank inspection practices as part of their emissions reduction strategy.
