UESI performs maintenance and inspections on steel and concrete structures, systems, and components to provide the plant with the information needed to make informed maintenance decisions. These include intake cribs, tunnels, and canals; traveling water screens; intake structures and circulating water pumps; condenser water boxes; storage tanks and gates.
UESI has inspection programs that address weld inspection, traveling water screens, and storage tanks. Our inspection programs are typically integrated in a comprehensive maintenance program. In the case of traveling water screens, for instance, we begin with a comprehensive inspection to determine the current screen condition and the optimum frequency and level of scheduled maintenance required. Following the initial inspection, an assessment is performed to determine precisely what repairs, replacements, or refurbishments are required. Based on this analysis, UESI develops recommendations that include any deficiencies requiring immediate action as well as a detailed annual maintenance program specific to the needs of each screen.
