Square Robot delivers autonomous, on-stream internal tank inspections that eliminate the need for confined-space human entry and operational shutdowns. Founded in Massachusetts, we deploy cutting-edge robotic platforms with high-resolution PAUT sensors to safely inspect hazardous oil, gas, and chemical storage tanks.

Our Expertise & Core Capabilities:

-On-Stream Autonomous Inspections: We deploy cutting-edge underwater robotic technology directly into in-service storage tanks—eliminating the need for product removal, degassing, or tank cleaning.
-Advanced Non-Destructive Testing (NDT): Equipped with Phased Array Ultrasonic Testing (PAUT) systems, our robots capture high-density corrosion readings with pin-point location accuracy within a 6-inch radius.
-Certified Compliance & Integrity Reporting: We deliver fully compliant API 653 and EEMUA 159 inspection reports, alongside API 581 and EEMUA 247 Extreme Value Analysis (EVA) risk assessments.
-Risk-Based Asset Management: We provide digitized, actionable data sets that allow operators to shift from costly reactive maintenance to strategic, predictive asset management.
