THE WORLD LEADER IN ROBOTIC TANK INSPECTIONS
Square Robot designs and manufactures autonomous, submersible inspection robots that are used by our service teams to perform internal inspections of aboveground storage tanks while they remain online and fully in service.
Make informed data-driven decisions
We equip our customers with a depth of information to accompany the comprehensive analyses completed after each inspection. All of this ensures everything passes regulatory compliance checks, and our clients are armed with all the information needed to keep their employees safe, reduce impact on the environment, and save costs they’d otherwise have to pay to take their tanks out of service.
Eliminating Confined Space Entry while providing API 653 & EEMUA 159 Compliant Tank Inspections
Regulatory Compliance without Down Time
Our robotic platform specializes in performing API 653 and EEMUA 159 certified inspections and associated services in a range of harsh tank environments while the product remains in the tank and fully in service.

Delivering Global On-stream Internal Robotic Tank Inspection Solutions
Square Robot is helping industries worldwide enhance efficiency with advanced on-stream internal robotic tank inspections, optimizing capital and operational performance while ensuring regulatory compliance.

State of the Art Robotic Technology
Our robotic systems are specifically engineered to maximize inspection coverage of the tank bottom. They are adept at positioning the Phased Array Ultrasonic Transducer (PAUT) close to the tank shell in the critical zone- where tank bottom corrosion can lead to catastrophic failures.

Tech-Driven Approach
Square Robot is uniquely positioned to provide data driven solutions in an ever-growing range of products and industry segments.

Enhanced Global Operations and Capabilities
Our efficient vans double as mobile warehouses and command centers, bringing equipment and personnel directly to your site. Our robots and gear are easily and affordably shipped worldwide via air cargo. We deploy and retrieve our inspection robots through the roof or side shell manway, tailored to the tank and product type.
Our Fundamentals
Environmental, Social, Governance
On-stream, internal robotic tank inspection eliminates the need for confined space tank entry, contains release of tons of carbon into the atmosphere, and also the solid and liquid waste historically required for traditional out-of-service tank inspections. People remain clear of dangerous working environments and the local community benefits from cleaner air.
Commercial Benefits
The real financial benefit of each on-stream internal robotic inspection runs from hundreds of thousands to millions of dollars per tank when compared to traditional out-of-service internal tank inspections. More importantly, keeping tanks in service means the tank continues to do its job, safely earning income and creating value, uninterrupted for a longer period of time.
Data Solutions
Vastly superior BIG Data sets from an array of high resolution sensors moves Tank Inspection from manual, interpretation-based reports to the era of digitization, allowing advanced risk-based analysis, machine learning, and artificial intelligence.
Operational Efficiency
Tanks remain in service throughout the on-stream inspection negating the need for alternate storage, cleaning, purging waste disposal, or manual inspection. Autonomous, submersible inspection robots deliver factual data supporting analyses by centralized teams of highly experienced senior inspectors.
