Underwater Construction Corporation (UCC) recently delivered a Carbon Wrap Service at a Mid-Atlantic Region US power plant ahead of schedule and under budget. UCC utilized a carbon composite repair system for structural strength upgrades to the power plant’s cooling water intake system.

UCC delivered an Engineered Design Solution to the Mid-Atlantic Region power plant, which supported their limited shutdown options. The project plan required no excavations, heavy equipment, or special ventilation, with minimal operational disruptions during installation. Similar repairs utilizing this high strength, low weight, and corrosion-resistant carbon fiber wrap were previously performed on other piping systems, which also provided the same significant schedule and cost reductions for this plant.

“In today’s energy-sensitive environment, reducing plant downtime when it is unavailable to produce power is paramount,” said Philip McDermott, UCC’s Vice President-Northeast and Mid-Atlantic Regions. “For UCC and our customers, the Carbon Fiber Reinforced Polymer engineered solution is a perfect fit. This client’s 66-inch diameter pipes were prepared, wrapped, and cured in one week resulting in significant cost savings, increased system reliability, and extended piping life”.

The strength-to-weight ratio of CFRP exceeds fifty times that of steel. CFRP makes structures last longer at a fraction of the cost and time of conventional materials and techniques Many energy sector plants, including nuclear, hydro, and fossil, face significant challenges regarding conservation and repair of their critically vital raw water intake and discharge infrastructure, and would benefit greatly from this type of repair. For more information related to underwater, moist environments, or dry CFRP applications, don’t hesitate to get in touch with UCC’s James Keeling at (860) 767-8256 x121 or jkeeling@uccdive.com.
