More than 100 hydroelectric facilities projects completed in 2023 The reliable, clean power generated by hydroelectric power companies is vital to modern society. But beneath what appears to be a tranquil surface, these large dam infrastructures face a constant barrage of challenges – from erosion and wear to environmental demands. To ensure on-going performance, optimized operations, and the protection of these critical structures, hydroelectric power companies turn to the specialized expertise of the hydropower maintenance team at UCC. Our highly trained commercial divers, underwater spec ..read more

Underwater Construction Corporation (UCC) recently completed another international nuclear diving project safely, on time, and under budget, this time with one of our customers in South America.  UCC‘s corporate office in Essex, CT, USA, supplied nuclear divers, underwater construction services and preventive maintenance of a Reactor’s Spent Fuel System. The nuclear divers removed the system, delivered it to the maintenance department for upgrades and service, and reinstalled and function-checked the unit. The nuclear power plant is now prepared to receive new nuclear fuel bundles for f ..read more

Erosion caused by water poses unique challenges for a variety of assets located on rivers, canals, lakes and coastlines. The powerful forces of waves, currents and tides can quickly wash away soil and displace particles through their movement, undermining the stability of underwater structures such as foundations, pipelines and installations. This natural process requires regular monitoring and maintenance to ensure that erosion and sediment control measures remain effective over time in the dynamic underwater environment. When a major port authority on the U.S. Gulf coast needed an alternati ..read more

UMPS Pit-Hog Robotic Dredge: Photo J. Meagher – UMPS The hydraulic dredging of pits, ponds & lagoons necessitates the integration of critical slurry processing operations for the dewatering and subsequent management of solids.   For mechanical dewatering operations of dredge slurries up to 2,000 gallons/minute (gpm) with typical solids contents of 4 – 8 %, basic unit process operations required are: debris scalping (<2-inch diameter), followed by coarse fraction vibratory screening (2-inch diameter x 3/8-inch diameter) and intermediate to fine fraction separation employing ..read more

Below is a small glimpse into just some of the recent UCC projects that were captured by our employees as part of the UCC Summer 2022 Photo Contest.   A huge “thank you” to all our divers and key field operations personnel who participated in this summer’s companywide photo contest. Hundreds of entries from all over the country were submitted.   These job site photos ranged from nuclear diving, underwater welding, and carbon wrapping services to underwater plant intake and discharge infrastructure services. Congratulations to the top ten entries and honorable mentions! As ..read more

UCC Completes TVA Browns Ferry Project for Carbon – Free Energy Generation Underwater Construction Corporation recently performed critical cooling discharge structure cleaning at the 3.8-gigawatt TVA Browns Ferry Nuclear Power Plant in Athens, AL, to keep this facility operating at maximum efficiency. In a July 25, 2022, article in the TVA Browns Ferry Nuclear News, it was presented that, “As the summer of high heat and record-breaking electrical demand continues, the Browns Ferry team has risen to the challenge of generating the maximum amount of carbon-free energy from all three units whil ..read more

Fossil-fuel and nuclear power plants all critically rely upon an adequate supply of processing and cooling water to safely and effectively operate within their facilities. Periodic water intake sediment removal requires careful coordination with diving service contractors, such as Underwater Construction Corporation (UCC – www.uccdive.com), and specialty slurry processing contractors, such as Underwater Mineral Processing Services (UMPS – www.mpsmaine.com), for integrated on-site sediment dredging/dewatering/water treatment operations. Adding the complexity that the removed sediments contain ..read more
