June 2015 – UESI Wins County-wide Inspection Contract for Storm Water Piping

CulvertUESI diving engineers are currently helping the state of Florida prepare for hurricane season. If Florida is hit with a major hurricane, storm water piping and culverts may mean the difference between severe flooding and the orderly run-off of millions of gallons of rainwater.

Pipes range in size from 30 to 84 inches, and are made of concrete or corrugated metal. UESI engineers have developed special report formats that cover the following structural elements: roadway, shoulders, safety features (guardrails, etc.), channel, channel embankment, headwall, wingwall, pipe material, pipe shape, pipe joints, sediment aggregation or erosion. UESI also provides full unedited video as well as a condition report for each structure.

Working closely with county governments, UESI is able to provide timely assessments that facilitate efficient rehabilitation when necessary. UESI also provides maintenance and repair of storm water piping systems.

May 2015 – UESI Assists Utility with Critical Path Emergent Work

May15UESI’s rapid response services were recently put to the test when a nuclear utility experienced problems with their fuel transfer system during a refueling outage. The call came at three AM. UESI was on site at 11:00 AM with the crews and equipment necessary to support 24 hour operations.

Because the exact nature of the problem and the repair method could not be determined until UESI divers inspected the fuel transfer system UESI was asked to mobilize with the capability to perform a mechanical and/or weld repair of the system.

Environmental and radiological conditions in the fuel transfer canal added to the difficulty. Water temperatures approached 100 degrees Fahrenheit, depth was 40 feet, and dose rates were extremely high in some areas. The conditions required that special precautions be taken and had the potential to severely limit stay times. Nevertheless, working closely with site engineers, maintenance personnel, and radiation protection technicians, the inspection was completed and repairs made within about 24 hours allowing the plant to resume refueling operations and saving millions of dollars in additional down time.
