McNary Station Services Units Upgrade

Construction Contract: McNary Station Services Units Upgrade

The work is located at the McNary Dam located in Umatilla County near Umatilla, Oregon.

McNary Station Service Units 1 & 2 Turbine-Generator Rehabilitation is a construction project to upgrade McNary's station service units 1 and 2. The station service units are 3.75 MVA, 4,160 volt, 277 RPM Francis type hydro-generating unit built by Electric Machinery MFG Company circa 1950, located at McNary Dam, Umatilla County, Oregon. Unit 1 is currently off line as a result of a winding failure in 2017, and Unit 2 operating continuously with no source of redundancy.

The work requires mobilization, pre-disassembly operational tests and measurements, hydraulic turbine generator unit disassembly, turbine runner disassembly, provide and install new stator cores and stator windings, new brushless exciter systems, new control circuits and annunciation/SER systems, rehabilitation to supporting turbine runner components, turbine runner reassembly, hydraulic turbine generator unit reassembly, operational tests and measurements, demobilization, and other optional provisions.

Generator repairs on Station Service Units include replacement of the stator core and windings and accessories to include design, manufacture, shop test, and deliver one complete set of stator bars, stator core laminations and all accessories needed for a complete winding assembly, ensuring circularity for each unit. Unit rotor repairs include cleaning, inspecting and testing the rotor. At the option of the Government, work would include reinsulating rotor field leads and refurbishing all rotor poles. Excitation systems shall be removed and disposed of in compliance with state and federal requirements, and new brushless exciter systems installed and tested. Existing control circuits and annunciation/SER systems shall be replaced with new control wiring with an annunciation/SER systems. Clean and inspect disassembled components, including turbine and generator guide bearings with an option for refurbishment of the original station service units 1 and 2 bearings and spares. Remove and dispose the existing surface air coolers and furnish, install, and test new surface air cooler assemblies, associated piping, and valves. Remove and dispose the existing fiberglass air shrouds and install new air shrouds for stator end turns.

The turbine scope of work includes disassembly of the Francis units, non-destructive examination of runner components, wicket gate bushing replacement, wicket gate stem sleeves replacement, links and levers bushings, painting the head cover and ancillary parts, upper and lower runner seal ring replacement, shaft sleeves replacement, and packing box replacements. Following the mechanical rehabilitation work, the units will require reassembly of the turbine, alignment, and commissioning. It is anticipated that the existing turbine runners will be reused and require minor repairs and painting. It is also anticipated that existing parts have lead based paint, and all work is required to comply with site operations, environmental protection, and safety and health provisions.

TIME FOR COMPLETION: The work shall be complete all repairs for Station Service Units 1 & 2 to include all testing , inspections, and commissioning by no later than 1000 calendar days following Notice to Proceed
