Summary of Scope of Work:

Lower Monumental Main Unit 2 Kaplan turbine runner was hydraulically fixed in September 2017, as the turbine was found to be leaking oil. The unit is currently operational in a fixed condition, however a timely fix to the leak is crucial to minimize corrosion damage to the internal hub components. The Lower Monumental Main Unit 2 is a vertical hydroelectric turbine-driven generating unit, with the generator manufactured by General Electric and rated at 142,105 kVA. The turbine runner is a 6-blade Kaplan-type rated at 212,400 horsepower (90 rpm), manufactured by Baldwin-Lima-Hamilton.

This scope of work is to repair the leak found at the turbine shaft to hub flange location. It was determined that the o-ring between the top of the Kaplan hub and the shaft lower flange is the location of the leak. In lieu of replacing the failed o-ring (requiring unit disassembly), the scope of work is to contain leakage by sealing the outer diameter of the shaft flange where it meets the hub. It will also include welded caps for each coupling bolt, and piping at the shaft jacking bolts to contain leaking within the flange face and routing it back to the static oil head.  Following repairs to the Unit 2 leak, commissioning support will be required in bringing Unit 2 back to Kaplan.
