Tank Robotics

Pioneers in the development of Intrinsically-Safe (IS) In-Service Tank Robotics and Inspection Services

Our team of Above Ground Storage Tank managers have decades of out-of-service and in-service tank inspection experience. We have a depth of experience and knowledge in high density ultrasound scanning, equipment design, fabrication, and safe deployments. BSI and affiliates have inspected thousands of tanks worldwide while in service.

The Inspection Process

BSI’s in-service tank inspection intrinsically-safe (IS) scanners and non-IS scanners are designed to inspect the bottom of above-ground storage tanks without removing the tank from service, and without personnel entry into the tank.

  • High density ultrasound scanners operate in both fixed and floating roof storage tanks.
  • Deployed with the tank full of product
  • A range of robotic equipment deployment options - from scanners that are maneuvered manually around the floor to multi-sensor remotely operated robots
  • Video inspection where optically clear
  • Precision navigation system
  • API 653 certified inspectors
  • 3D LIDAR laser scan tank analysis: settlement outer roundness, plumbness, berm capacity analysis, etc.


  • On-Site Preliminary Result Reporting
  • Rapid Final Report Turnaround
  • API 653 Compliant

When In-Service Makes Sense

  • Where unknown conditions exist
  • Integrity recertification
  • A new tank where corrosion rate is not known
  • Older tanks with known degradation

Benefits of In-Service Tank Inspection

Save Time & Money

Historically, when an above-ground storage tank requires a routine inspection, the tank must be taken out of service presenting an interruption in operations. Alternatively, an in-service tank inspection provides the tank owners with the ability to plan for the optimum time for a full out-of-service inspection, if necessary.

Ultrasound & Settlement Data

BSI offers high density ultrasound tank floor scanning with traditional compression wave ultrasound to collect floor thickness and settlement data at the same time. This provides a more realistic picture of tank settlement, a better analysis of tank floor integrity and a realistic calculation of the remaining useful floor life of the tank.
