Solex Environmental's "Maverick" fuel storage tank inspection robot recently successfully completed a bottom floor inspection of an Amoco floating-roof tank near Baton Rouge, La. The robot gathered 100,000 data points during the three-day, in-service demonstration inspection of the tank, which held 206,000 barrels of light crude oil, according to Don Hartsell, president of Solex's robotics division in Houston. A demonstration inspection of a USAF floating-roof jet fuel storage tank at MacDill AFB, Fla., began last week. The Amoco inspection saved $185,000 in tank out-of-service costs compared with renting barges for temporary crude oil storage while a manned inspection of the tank was performed. Use of the robot also prevented the release of about 100 tons of carbon dioxide into the atmosphere by eliminating the need to purge and burn off tank fumes.
