Blasting and coating oil tanks during winter months
Our customer had been contracted to prep the surfaces and to apply a coating liner system on the interior sections of two newly constructed giant crude oil storage tankers. Each tank was 225 feet in diameter and 62 feet high with a floating roof. The assignment was to abrasive blast the inside surfaces of the steel tanks, clean out the abrasive, prepare a clean, dry surface for coating and spray the coatings on the floors and walls to a height of two feet above the floors with an epoxy coating. The two-foot height for coating the walls was specified to protect the surface against water that accumulates in the tank and can rise to that level below oil stored in the tanks.
