The Work shall be performed as shown in the Drawings, stated in these Specifications, or reasonably implied from them all in accordance with the Contract Documents. The Work in this Package shall be performed on a Firm Price Basis, unless otherwise noted. For the purpose of this document, Colorado Springs Utilities will be referred to as (“UTILITIES”). UTILITIES’ Project Manager will be referred to as (“PM”). CONTRACTOR, individual(s), or companies responding to this solicitation shall be referred to as (“CONTRACTOR”). LOCATION: The Ray Nixon Power Plant is located in the City of Fountain at exit 125, off of I-25. The plant has an elevation of 5,570 feet above sea level. The proper mailing address for the plant is: 6598 Ray Nixon Road, Fountain, CO 80817. 2.0 Scope and Background

2.1 Scope The following description, while not intended to cover all details, outlines the major Scope of Work for the disassembly of Ray D. Nixon’s unit 1 steam turbine and associated auxiliary equipment for a measurement inspection. All materials, tools, and workmanship (except where excluded) in all respects shall be furnished by this CONTRACTOR even though not specifically mentioned in these specifications. CONTRACTOR shall include all labor, materials, transportation costs, storage, equipment, etc., necessary to successfully complete the Work as herein specified. The intent of this scope is to remove the HP/IP & LP rotors. The lower casings and diaphragms will not be removed for the purposes of the measurement inspection; however the end pack casings will need to be removed from the HP / IP section for the measurement inspection. During the course of the inspection the CONTRACTOR shall make repair recommendations on items discovered during the course of the inspection. All repairs not listed in the Statement of Work will be performed on a T&M basis. CONTRACTOR shall provide a detailed schedule with emphasis on the date that the rotors have been removed from both sections (HP/IP & LP) so measurement inspections can commence. CONTRACTOR will have




Page 2 of 33

limited access to the steam turbine during the measurement inspection, which will take seven (7) working days from the date of commencement.

2.2 Background The turbine is a General Electric Model Type D-5, 3600 RPM, tandem compound reheat unit with a double-flow low pressure section. The high pressure and reheat stages are housed in an area with double shell construction. The HP section consists of eight (8) stages and the reheat section (IP) consists of six (6) stages. The HP/IP rotor is approximately 19 feet-8 inches long, weighs 31,877 pounds and has a 55 11/16-inch diameter at its widest point. The LP section consists of twelve (12) stages. The LP rotor is 21 feet 10-1/2 inches long, weighs 58,000 pounds, and is 8 feet 2 ¼ inches at its widest diameter. Unit Serial No. is 180X743. The unit has been in service since 1980 and has approximately 260,000 operating hours. The last outage that took place on the HP/IP section was 2007 and the LP section in 2005. The unit will be removed from service the evening of Friday, March 4, 2011 and the anticipated on-line date is Monday, April 4, 2011. The Work covered under this scope is scheduled to begin on Monday, March 7, 2011, with a scheduled completion date of April 3, 2011, @ 11:59 PM. The Work described herein will be performed on a turnkey basis. CONTRACTOR must be able to demonstrate the necessary qualifications as outlined in Section 3.8. If CONTRACTOR decides to subcontract any of the items outlined in this section, they must provide a list of subcontractors that would be used to complete the Work. All subcontractors are subject to UTILITIES approval.

Page 17 of 33

Note: During pre-outage N2 testing, it was discovered that the HP-IP turbine has steam leakage in excess of 150,000 lbs/hr. Previous outage reports have shown indication of case distortion. Prior to disassembly the CONTRACTOR will perform the following inspections / tests.

3.7.4.1 Pre-Disassembly Checks / Procedures for HP-IP Section

3.7.4.1.1 CONTRACTOR will use feeler gauges to measure the gap along the horizontal split-line on HP-IP casing. Findings will be mapped on casing drawing No. 882E869 REV.2 (Arrangement of Joint Studs) and included in final report. Excessive gap measurements will be reported to UTILITIES’ representative Manny Zeringue or other designated UTILITIES’ representative.

3.7.4.1.2 CONTRACTOR will check for bolt tightness along HP-IP case

horizontal split-line prior to disassembly. Findings will be mapped on casing drawing No. 882E869 REV.2 (Arrangement of Joint Studs) and included in final report.

3.7.4.1.3 Insert hold down support shim, Part #7, prior to unbolting split

line. Reference GEI-69576C, GEI 79468D, and GE drawing number 519C502 (Rev.9) for details on this procedure.

3.7.4.1.4 Remove coupling bolts. 3.7.4.1.5 Take and record rotor thrust measurements prior to

disassembly. A hydraulic jack with a known force must be used when thrusting the rotor. The force to jack the rotor should not exceed 5 tons. Reference GEI-88667 for further instruction.

Note: The thrust bearing, which is located in the front standard, should be left assembled. The thrust bearing will prevent excessive differential movement between the rotor and stationary parts from occurring as the shell and rotor are being jacked.

3.7.4.2 Loosening of Bolts on HP-IP casing

CONTRACTOR shall perform hot loosening of the HP-IP turbine horizontal joint studs and cap nuts. If it is necessary to cut nuts and studs, CONTRACTOR shall notify UTILITIES’ representative Manny Zeringue. Induction heating method is to be used for opening and tightening of horizontal joint bolts. Bolt heater will be provided by CONTRACTOR.




Page 18 of 33

Indicators must be set up to measure the movements of the shell and HP rotor as they are being jacked. An indicator should also be used to measure any movement of the remaining rotors. If the remaining rotors move, wedges made of hard wood should be used to block the remaining rotors to hold them stationary.

3.7.4.3 Jacking and lifting HP-IP Upper Shell Casing

At a minimum, the following documents shall be referenced for disassembly of casing and lifting rotor: 3.7.4.3.1 GEI-40800C – HP Turbine Shell Joints (Method of Separating

The thrust bearing is located on the main shaft of the turbine. Independently mounted inside the standard, the thrust bearing absorbs the axial thrust of the turbine and generator rotors. The tapered-land thrust bearing consists of two stationary thrust plates and two rotating thrust collars on the turbine shaft which will provide the front and back faces to the bearing. Reference: GEK 46382F, Machine and Operating Limit Recommendations for Tapered Land Thrust Bearings in Sliding Front Standards.

3.7.5.2 Inspection Criteria – Tapered-Land Thrust Bearing:

3.7.5.2.1 Receive visually and dimensionally inspect thrust plates. Record incoming flatness and land geometry

3.7.5.2.2 Perform ultrasonic inspection of babbitt bond 3.7.5.2.3 If the ultrasonic test results are acceptable, machine each thrust

plate to restore flatness and geometry to factory specifications. Note: If porosity is detected in the babbitt during machining, the thrust plate must be re-babbitted. 3.7.5.2.4 If the ultrasonic test results are not acceptable, or porosity is

detected in the babbitt while machining, repair each thrust plate as follows: a. Machine out old babbitt b. Prep and re-babbitt each thrust plate c. Machine to restore flatness and geometry to factory

specifications d. Perform final inspection and record flatness and land

geometry.
