New autonomous robot for tank inspection completes successful deployment


Square Robot has announced the successful outcome of a Joint Development Programme with ExxonMobil to design, build and deploy a submersible autonomous robot for tank inspection

The robot is capable of entering above ground storage tanks through a side entry “launcher” to inspect the internal surfaces of the tank while the tank remains in service. It can safely enter more volatile liquids, such as gasoline, stored in tanks with an internal floating roof.

The service offers significant environmental, health and safety benefits, eliminating the release of hydrocarbon vapour and waste associated with taking a tank out of service as well as reducing personnel risk. Additionally, with the tank remaining in service and operational, the total cost associated with traditional inspection services is dramatically reduced. Clients receive a comprehensive data set regarding the state of their asset, enabling more informed decisions.

The robot was deployed into a 140’ diameter above ground storage tank containing 150,000 bbl of gasoline at ExxonMobil’s Baton Rouge facility. Representatives from both companies witnessed the successful deployment, survey and recovery of the robot in full compliance with the original design objectives.

“We are happy to work with innovative companies like Square Robot to deliver solutions that make our operations safer, more efficient and reduce environmental impacts,” said Tim Westhoven, Technology Scouting & Ventures senior advisor, ExxonMobil.

“Working with ExxonMobil on this joint project has been a very rewarding experience for Square Robot. The results speak for themselves. I believe ExxonMobil has brought out the best in Square Robot and leveraged our ability to quickly develop world leading technology capable of having a major impact at a company of ExxonMobil’s scale, with no compromise,” said David Lamont, president and CEO, Square Robot.
