Cavitation Repairs for Unit 3 Draft Tube Liner and Turbine Runner at Jones Bluff Powerhouse, Selma, AL
Market Research and Sources Sought Notice for information on capability and availability of potential contractors interested in proposing a Firm Fixed Price Contract for the repair of turbine cavitation damage to Unit 3 at Jones Bluff Powerhouse, Selma, AL. The scope of work consists of using the 256-inch diameter turbine runner as the turning fixture for mounting various measuring, excavating, cutting, welding, grinding, sanding, surfacing, and finish machining tools and employing procedures necessary to restore a large area of the adjacent turbine water passage (draft tube liner) to original hydraulic shape and integrity. The scope of work will involve rigorous pre and post work unit alignment checks and possible alignment of the rotating hydro unit components to achieve plumb and/or center conditions. The area of water passage to be restored includes a vertical band of deteriorated water passage approximately 73 inches in height which extends basically 'from the inlet edges of the runner blades to the trailing edges. The work will include excavating the entire aforementioned band to solid metal (including possible cutout of and replacement of panels not found to be of sufficient thickness), overlay of prepared surfaces with stainless steel weld metal, and finish machining to original hydraulic profiles and finish. In addition, the work will include extensive anchorage to fixed structure and back-grouting of repaired area to withstand warpage and distortion during the weld process and to insure support of repaired water passage by structure concrete behind. Anchorage will consist of a defined boring pattern of holes, steel rebar type anchors set in epoxy-type setting bonding, and welding of rebar to water passage liner. Contractor shall provide all labor, material, and equipment to perform the previously described work including machinery and drive components necessary to turn turbine runner during the work.
