EDTECH: LEVERAGING AI-POWERED TECHNOLOGIES TO TRANSFORM THE LEARNING EXPERIENCE
1. Technology overview
Square Robot, based in Westborough, Massachusetts, makes the SR-3, an autonomous robot for internal inspection of aboveground storage tanks while they stay in service. The company serves refining, power generation, midstream, renewables, aviation and chemical customers.
The SR-3 platform enters a tank without confined-space entry and uses patented navigation to take corrosion readings within a six-inch radius, with phased array ultrasonic testing (PAUT) and digitized inspection reports. The company also offers inspection services performed by experts using the SR-3. Inspections are designed to support API 653 and EEMUA 159 requirements.
2. Highlighted features & specifications
- SR-3 robot: autonomous robot that inspects aboveground storage tanks from the inside.
- On-stream inspection: tanks stay in service with no confined-space entry.
- Patented navigation: corrosion readings within a six-inch radius.
- PAUT: phased array ultrasonic testing for wall thickness data.
- Digital reports: digitized inspection reports for integrity teams.
- Inspection services: expert inspections performed with the SR-3.
3. Potential application
Internal inspection of crude and product tanks at Vietnamese refineries. Tank integrity surveys at fuel terminals and ports. Inspection of chemical storage tanks without draining or manual entry.
4. Benefits
The company states that on-stream inspection removes confined-space entry, with more than 236,000 confined-space hours eliminated across 400+ tanks. Its PAUT system reached 99.6 percent confidence against API 653 Annex G sizing expectations. Digitized reports speed up integrity decisions.
5. Market trends & opportunities
Operators of fuel and chemical tanks want to avoid shutdowns and confined-space entry while meeting integrity standards. Vietnam's refineries, fuel terminals and petrochemical sites hold many aboveground tanks that face the same inspection cycle.
6. Other information
Based in Westborough, Massachusetts. A December 15, 2025 announcement on its website covers new funding and a collaboration. Reports 400+ tanks inspected across 17 countries. Inspections align with API 653 and EEMUA 159.
