The New York Power Authority’s Robert Moses Plant is one of the largest hydro-electric generating facilities in the U.S. The facility moves 25 turbines with 748,000 gallons of water per second to produce a maximum voltage of 2.6 million kilowatts of electricity. This electricity supports communities across the North-East. Since its construction in 1961 Clark has always had a vital role in various projects around the plant. Being a 62 year old facility, general maintenance and capital projects are crucial to its longevity. In this specific project, a storm drainage outlet was eroding the shoreline that supports the entire base of the plant. It was critical that the drainage system be reconstructed and the shoreline re-stabilized.
Clark was involved with the facility’s contracting team right from the beginning of the project to establish feasibility and the best approach. Ultimately it was determined the drainage line would be re-routed to a different discharge point. With a new path in place, there was still the need to remove an existing 24,000lb concrete head-wall as it was barely being supported on the eroded shoreline. Clark designed a special rigging configuration using custom single eye wire rope slings & wedge sockets to connect to the piece of concrete. Clark’s well prepared rigging and operating crews used the custom rigging arrangement with a Liebherr LTM1200-5.1 (240T) crane to successfully remove the head wall. The crews additionally provided crane & rigging services to set erosion netting and 140 tons of large rock over the bluff in efforts to stabilize the shoreline. A specialized self-releasing rock grapple was procured to set the rock. Clark is committed to providing solution-based services to our customers.
A sincere thank you to NYPA, Mark Cerrone Inc, and the Clark Rigging crew members that safely completed this project given the special conditions.
