At the Two Rivers, WI Nuclear Power Plant, the submerged offshore HCS intake screen provides cooling water for the power plant. The intake is 30 feet in diameter and several feet. below the surface of water. The intake screen was fabricated with HDPE blades at six-inch clear ...
The trash racks with frames for the Victoria Texas Power Plant were fabricated using HDPE for the blades, pultruded FRP structural members for the frames and 316 stainless steel for the ...
67,900 acre reservoir created for flood control and electric generation. 94’ high and 3,979 dam across the Tennessee River generates 123 megawatts. Only 15% of the 890 miles of shoreline is developed. Average depth of Guntersville Lake is 15’ with a maximum depth of 45’. Premier angling destination with a robust and diverse fishery. Abundance of aquatic vegetation including ...
Year: 2018 Running Gear: 2 Vertical shaft Francis turbines with synchronous generators Scope: Replacement of control system and exciters This hydroelectric plant is located in central MA on a highly developed river, with multiple hydro plants operating both upstream and downstream of the project. Originally constructed in 1918 by a local manufacturing company, the project today consists of ...
PHT was selected to provide upgraded controls and replace the excitation system, while another party was hired to provide all new switchgear, station electrical service, and fiber optic lines from the powerhouse to the trash rack and dam. All of the old troublesome control and switchgear equipment was demolished and removed from the upper control level of the ...
The project today consists of a masonry overflow dam and canal gate intake structure, a 1300 foot long canal, forebay, trash racks for each of the generating units, and a powerhouse with three vertical shaft generating units, for a total capacity of 3.3 MW. ...
The Bureau of Reclamation employees learned the basics of maneuvering, tether handling and how to get the ROV free from entanglements, and inspected the trash racks at a dam from a vessel – without securing the intakes. ...

Global Diving & Salvage, Inc was contracted by Salt River Project (SRP), operator of Horse Mesa Dam, located 65 miles northeast of Phoenix, AZ, to provide project management and diving services to make repairs of Units 1 through 4. The work on Unit 4, located in 160 feet of water, and on Units 1, 2, and 3, located in 260 feet, necessitated the use of saturation divers. Saturation diving ...
Recent work has improved understanding of the performance of the Acoustic Scintillation Flow Meter (ASFM) in hydroelectric intakes, particularly the factors affecting the accuracy of the results. The primary cause for systematic (or bias) errors was found to be coincident, strong inhomogeneities in the intensity of small-scale turbulence and the mean velocity in the measurement plane, such as are ...
