Case Studies

Aboveground Storage Tank Shell

Effective UT coverage

Scanned 60 feet²
(5.6 meters²) per minute

Collected 39
million UT readings

Saved nearly $1 million on repair costs

Challenge

Internal coating failure causing corrosion
Traditional full-coverage inspection methods require extensive downtime
Replacement cost for the one tank shell would cost $1.2 million

Solution

Full-coverage RUG inspection using TOKA® 4 robotic inspection platform
Gecko Portal® software

Result

Full-coverage inspection completed in 2.5 shifts instead of 5 weeks for traditional AUT
Significant cost savings for inspection
No scaffolding or dedicated company resources required
39 million UT readings obtained
Saved the refinery millions of dollars in tank replacement costs by pinpointing areas in
need of repair
