About this file
This document provides details for a federal construction contract opportunity with the U.S. Army Corps of Engineers Nashville District. The solicitation seeks a firm fixed-price contract to rehabilitate turbine generator units at Old Hickory Power Plant in Hendersonville, Tennessee, with an estimated value between $25-100 million. The scope of work includes rewinding generators for units 1-3 to increase output to 45 megawatts, replacing turbine runners for the same units, and potentially replacing unit 4's turbine runner. Additional electrical, turbine, and mechanical work involves upgrades and refurbishment of systems to support the increased load. The two-year project consists of model testing and design for the first unit, followed by 18-month installation periods for the remaining base units. The pre-bid site visit will take place on May 5, 2022, and all visit requests must be submitted in advance to the specified POC. The question and answer period is open, with technical inquiries to be submitted through the listed ProjNet website.

DETAILS DE LA DISPOSITION / DISPOSITION DETAILS :
The following steps shall be followed to install the oil pipe:
1. Since the oil pipes are passing between circuit rings 7 & 9 (neutral side), the section of the pipe shall be insulated using the same insulation procedure that was previously submitted for the circuit rings (12 half-lapped layers of insulating tape. Apply one coat of insulating resin 15120A on the pipes and between each layer of insulating tape. When finished with the insulating tape, apply resin 15120A and add one half lapped layer of glass tape over the insulation for mechanical protection)
2. The minimum airgap distance between the insulated pipe and circuit rings shall be greater than 0.8”. Mechanically secure the pipe to maintain equal distance between the two rings
3. It shall be added 2 dielectric unions at the end of the insulated section of pipe (one in each end), see picture below:
4. Perform pressure test for that section as per system parameters
5. A Megger/Hi pot is not required now (after pipe installation), because a final hipot/DC ramp test will be done after rotor installation

See Description
When reinstalling UGGB oil pan fill and drain pipes (items 34 & 35 of OEM dwg 528e594), the circuit ring interferes with the OEM path.
OEM routing was just above circuit ring but new circuit ring is taller. See attached pictures.
