API 653

Our autonomous robotic inspections provide our clients with exceptional data, while significantly reducing the time, cost, and risk to personnel associated with out-of-service inspections. But just as important as the data we collect during an inspection is the resulting API 653 Report. Following an inspection, we summarize all collected data into a comprehensive report that we then deliver to our client. From PAUT coverage maps of the tank bottom — including the critical zone —to visual inspection of the tank internals, the valuable information contained in the reports informs our client’s decisions on their aboveground storage tanks.

Tank Bottom Thickness Survey

Depending on tank conditions, our robots are capable of providing up to 90% tank floor inspection survey coverage to support API 653 tank bottom thickness and corrosion using either Pulsed Eddy Current (PEC) or Phased Array Ultrasonic (PAUT) inspection payloads. Our state-of-the-art sensor packages capture a significant amount of data that is used to perform quality checks, eliminate environmental abnormalities, and generate high quality reports that fully comply with API 653 requirements.

Internal Visual Inspection

Our robots support two high definition cameras that can be focused on the tank floor, internals, wall, or roof to provide qualitative visual information regarding the integrity and health of your tank infrastructure and stored product.

Our Process

Mobilization

The team arrives on site and completes all necessary safety, permitting and 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.

Obstacle Survey

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 support columns.

Tank Bottom Coverage and Inspection Data

Once the robot has detected and mapped all obstacles, the robot begins a grid survey of the tank floor, collecting thickness measurement and visual data with up to 95% coverage including the annular ring and critical zone.
A 45’ diameter tank can be surveyed with one full day of operations.

PAUT
or PECA each technology have the ability to deliver accurate thickness data, enabling the tank operator to make informed decisions to extend opening intervals. 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’.

API 653 Report

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
tank owner.

Deployment

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 support columns.
