Sources Sought -- 140R10-25-R-0001 Turbine Runners Cavitation Repair, Nate Washington Power Plant, Grand Coulee Dam, Washington

This is a Sources Sought announcement only. THIS IS NOT A REQUEST FOR PROPOSALS, QUOTATIONS OR BIDS, NOR A PROPOSED SYNOPSIS OF A PROPOSED CONTRACT

ACTION UNDER FAR SUBPART 5.2 and no contract shall be awarded from this notice. No reimbursement will be made for any costs associated with providing information in response to this Sources Sought or any follow up information requests. No solicitation is currently available.

Draft specifications are subject to change. This market research is to gain knowledge of interest, capabilities, and qualifications of interested Small Business firms. Responses to this Sources

Sought will shape the acquisition strategy in developing a competitive requirement.

The Columbia-Pacific Northwest (CPN) Regional Office of the U.S. Bureau of Reclamation is conducting market research for a Turbine Runners Cavitation Repair construction contract. The work location will be at the Grand Coulee Dam and Power Plant, approximately 90 miles west of

Spokane, Washington, and 60 miles north of Moses Lake, Washington, in Okanogan County, near the city of Coulee Dam.

The principal components of work will be:

A. Turbine Runner Cavitation Repair – Grand Coulee Dam & Power Plant; Coulee Dam, Washington. Six (6) G19, G20, G21, G22, G23, and G24 hydro-electric turbines.

1 *Assessment of cavitation damage to the generator runners

2 *Estimation of time and welding material needed to repair cavitation damage

3 Grinding to runners in preparation for repair

4 Welding to repair runners

5 Grinding to runners to restore contours of the blades

6 Pre-mobilization site meeting, mobilization, demobilization

NOTES TO ABOVE:

*1. Damage assessment will be conducted by the Government and communicated to the contractor both ahead of time for material ordering and initially upon on-site meetings and mobilization.

*2. Timeframe of cavitation repair (i.e. the window) is set by Government due to maintenance outages. Contractor will manage their schedule within Government constraints to meet repair deadlines.

The turbine runners which may be contracted for repair work per this specification are those in units G-19 through G-24 in the Grand Coulee Third Powerplant (TPP).

1. The phrase “turbine runner” includes the crown, outer ring, hub, air vents and blades, which make up the “runner” proper, as well as the top part of the draft tube discharge ring

(immediately below the runner). Each Grand Coulee turbine contains 13 blades (also called

“buckets” or “vanes”).

2. The Grand Coulee G-19 through G-21 units are equipped with 820,000 HP Francis-type turbines, designed by Dominion Engineering Works, Ltd., and manufactured by Williamette

Nate Washington Power Plant, Grand Coulee Dam, Washington

Iron and Steel Co. The runner throat diameter is 34 feet. The base metal of the runner assembly is cast steel, per ASTM A 216, Grade WCB. The original stainless-steel overlay was accomplished using alloy 308L.

3. The Grand Coulee G-22 through G-24 units are equipped with 960,000 HP Francis-type turbines, designed and manufactured by Allis-Chalmers. The runner throat diameter is 32 feet. The base metal of the crown and vanes (blades are cast steel, per ASTM A 216, Grade

WCC. The base metal of the runner band is steel, per ASTM A 516, Grade 70.

The Grand Coulee turbines have been in service since the mid-1970’s and have each gone through several major overhauls. Each has had different work crews and varying amounts of time to work with. Thus, no two units are in the same condition. Most of the runner is carbon steel, but a significant amount of stainless steel exists, from initial construction and previous repair areas.

Previously applied protective coatings consisted of primer and various kinds of epoxy paints.

Several turbines were coated with a zinc-rich primer.

The turbine types have noticeably different properties and characteristics with respect to the nature of damage seen:

1. On Grand Coulee units G-19 through G-21, cavitation damage is mostly seen as large

(approximately 6” wide by 12” long), eroded cavities on the lower pressure side of the blade, where it meets with the outer runner ring. These cavities are close to the leading edge (within a few feet) and can be several inches in depth. Some areas exhibit cavitation-enhanced corrosion (severe surface pitting, with a porous appearance like some kinds of cheese). Although these units are not known for having cracks in the blades, some have been found in the past.

2. On Grand Coulee units G-22 through G-24, damage is mostly seen as cavitation enhanced corrosion in the crown area. Several of the units have already been clad with stainless steel in the most troublesome areas. The low- pressure side wall of many of the blades have severe surface pitting that covers a large surface area. The leading edge of most of the blades exhibit corrosion erosion. These units have historically had cracks along the lower leading edge of the blade, as well as the upper and lower trailing edges.

B. The magnitude for this construction project is between $5,000,000 and $10,000,000 for the term of this five (5) year requirements contract; however, no guarantee is made for orders.
