We keep storage tanks in service by using the latest in robotic inspection technology to provide floor thickness maps without having to empty and open your tanks.
The team arrives on site and completes all necessary safety, permitting and JSA tasks. Our equipment is moved to the inspection site and prepared for deployment. This is completed within a few hours of of arriving at the site.
The operator's control station is set up. The robot is unpacked and checked out to ensure it is ready. The robot is then hoisted on to the tank top and made ready for launch. Once in position, the hatch is opened and the robot is lowered to the tank floor and detached.
The robot then lifts off of the floor and hovers. It then completes an obstacle detection survey, noting the presence of things like roof drains, fill lines, and sumps.
Once the robot has detected and mapped all obstacles, the robot begins a grid survey of the tank floor, collecting thickness measurement data with up to 95% coverage
VERITANK can provide tank bottom thickness data using Phased Array Ultrasonics (PAUT) or Pulsed Eddy Current Array (PECA). A 45’ diameter tank can be surveyed with one full day of operations.
After the mission is completed the data is off-loaded from the robot and analyzed. With careful review from an API 653 inspector, a detailed report is prepared for the
NDT (nondestructive testing) data is collected using PEC or PAUT. Each technology has the ability to deliver accurate thickness data, enabling the tank operator to make informed decisions to extend opening intervals.
Whether using PECA and/or PAUT position and scan speed is highly controlled and logged allowing for accurate data interpolation. We collect all of the available data unlike traditional UT where only problem areas indicated by MFL (or other means) are ‘scrubbed’.
Processed scan data (A-Scan & C-Scan) is merged with highly accurate positioning data from the robot and a composite map of the tank floor is created.
The tank floor thickness map is processed using the customer's remaining wall thickness criteria. Robot imagery from the two onboard cameras can also be recorded and included in the report. From there, you will be able to make the best decisions about how to manage your infrastructure.
With help from industry partners, we have assembled an experienced team of qualified tank inspection professionals. Our processes have been closely scrutinized and vetted to assure you that every procedure is documented and safe.
VERITANK has partnered with industry leading NDT providers allowing us to integrate best in class sensors into our robots.
