UESI engineers, inspectors and divers can support a variety of marine construction and commercial diving projects for water utility, dam, power generation, transportation, industrial, and government, customers.
UESI divers provide a variety of radiological diving services in reactor vessels, fuel pools, suppression pools, and tanks around the world.
UESI provides qualified inspectors both above and below water to perform ISI, ASME Section XI VT-1 & VT-3 Examinations, and ANSI N45.2.6 Coating Inspections under our 10FR Appendix B QA Program.
UESI provides welder and weld process qualification for specialized underwater welding of stainless and carbon steel in our hyperbaric weld chamber.
UESI provides wet welding services to nuclear codes and AWS requirements under our 10CFR Appendix B QA Program
UESI provides testing services such as Design Basis Accident (DBA) testing for safety related nuclear plant coatings under loss of coolant accident conditions.
Diver preparing surface for application of UESI’s proprietary underwater epoxy, UESI provides underwater coating services to protect safety related structures systems and components in nuclear power plants.
UESI diver entering a condensate storage tank at a nuclear plant to perform cleaning and inspection. UESI can also provide remote inspection services.
UESI divers help to maintain critical cooling water systems vital to a nuclear plants operational efficiency & safety
UESI Nuclear Coating Specialists perform detailed surveys of primary containment coatings to determine whether coatings meet plan licensing basis requirements to assist in maintenance planning.
UESI Nuclear Coating Specialists plan and perform detailed surveys of safety related and balance of plant coatings to determine whether coatings meet plan licensing basis requirements to assist in maintenance planning.
UESI QA specialists and QC inspectors develop and implement quality assurance and quality control programs to ensure safety related coatings are properly applied in Service Level I areas such as the suppression pool.
Experienced UESI NACE & ANSI Nuclear QC inspectors provide oversight for critical applications of safety related Service Level I coatings on critical structures such primary containment, the suppression pool, and condensate storage tanks.
UESI Nuclear Coating Specialists perform coating and corrosion surveys of buried pipe to record as-found condition and estimate remaining service life.
Detailed assessment of buried pipe is crucial to maintaining the safe operating condition of nuclear plants.
UESI has been a leading global provider of specialized services for the nuclear power industry for over 25 years. See our complete list of services below.
UESI divers provide environmental diving services in support erosion control projects.
UESI has participated in several large scale reef restoration projects to restore damaged coral reef formation as viable habitats.
UESI provides a full range of commercial diving services including emergency 24 hour response.
June 2015 – UESI Wins County-wide Inspection Contract for Storm Water Piping
UESI 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
UESI’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.
