Tank Inspection Robotics

Tank Inspection Header

The Global Leader for In-Service Tank Robotics.

BSI has used robotic technology to internally inspect tanks and confined spaces for over 35 years. The world’s largest provider of in-service AST inspection robots and the leader in ultrasound remote monitoring systems, no other company can compete with our depth of experience in high density ultrasound scanning, equipment design, fabrication, and safe deployments.

Robot Line Up
Save Time & Money

Historically, when an aboveground 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 is a preliminary examination to determine tank condition, thus affording tank owners the ability to plan for the optimum time for a full out-of-service inspection.

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 the tank settlement, a better analysis of all aspects of the tank, and a calculation of the remaining useful floor life of the tank.

All-Inclusive Inspection Package

The BSI In-Service Tank Inspection package is available to provide skilled professionals for your project as well as the robotic equipment, software, and technical support to match each customer’s unique needs and workflow.

The Ultrasound Difference

Historically, the integrity of equipment has been assessed manually. In addition to being an inconsistent and unreliable method, manual assessment can be disruptive to business, is time intensive, and costly. A more proven and predictive approach is to use ultrasound as the diagnostic tool.

The Inspection Process

BSI’s in-service tank inspection intrinsically-safe (IS) scanners and non-IS scanners are designed to inspect the bottom of small diameter storage tanks without removing the tank from service, and without personnel entry into the tank. Our high density ultrasound scanners are designed to operate in both fixed and floating roof storage tanks and can be deployed, with the tank full of product, through an 18-inch or greater diameter inspection manway.

BSI robotic equipment is delivered in a range of sizes and deployment options from scanners that are maneuvered manually around the floor to multi-sensor remotely operated robots.

In-service tank inspection manual scanners are not motorized. They are deployed into a tank manually. One or more technicians, located on the roof of the tank, manipulate the scanner along the tank floor in a predetermined pattern that satisfies specific customer inspection criteria. As with other BSI products, the robotic solutions utilize ultrasonic thickness measurement as the primary measurement technique. During the inspection, the operator records the scanner path manually and data analysis is conducted on-site or off-site. Automatic navigation solutions are also available. Daily reports are produced.

Common Applications
  • Where unknown conditions exist
  • When a tank needs reassessed
  • A new tank where corrosion rate is not known
  • Older tanks with known degradation

Integrity is Our Number One Asset.

BSI excels in translating the precision and reliability of ultrasound, previously only found in a laboratory setting, into real-world field environments.

Our engineers and scientists are experts in the development of unique, rugged ultrasound sensors and “Smart” scanners as well as the design of signal processing software that enhances and preserves data quality. Read More
