The file is a technical specification document for a repair project at the Little Goose Powerhouse Unit 3, located on the Lower Snake River near Starbuck, Washington. The work involves addressing an oil leak at the turbine shaft to Kaplan hub connection, specifically requiring three key repair actions: fabricating and installing a sealing ring at the hub connection flange, installing stainless-steel tubing, and welding thirty caps to seal coupling bolts and nuts. The project is being solicited by the Department of the Army Corps of Engineers Engineering District Walla Walla, and will be performed within the powerhouse of Little Goose Dam, which has six main generating units, with this specific repair targeting Unit 3. Notably, the contractor will not be required to disassemble or reassemble any existing components during the repair process.
