1.2 This site survey will have the following objectives in support of the Rapid City to Otter LakeCompressor Package relocation:

1.2.1 Assess the condition of all the R-R provided equipment, with respect to its suitability for the newlocation

1.2.2 Review all the R-R provided hardware with respect to obsolescence and make appropriaterecommendation for replacement

1.2.3 Review project specifications with the customer to assist in the engineering work required as partof the relocation project.

1.2.4 Provide the customer with the relevant R-R Global Engineering Methods (GEM) and GlobalEngineering Reference (GERS) pertaining, but not limited to, EC&I interfaces and cabling as wellas shipping preparation and preservation requirements.

1.2.5 TCPL will have the responsibility of disassembly, shipping preparation, transportation, andreassembly of the entire package. For instructions please refer to Operations and Maintenancemanuals. R-R has offered to provided Technical Direction and Instruction (TDI) during the teardown.

2 BACKGROUND

A detailed site survey has been performed by Rolls-Royce for the existing gas turbine packageSO-5036 Station 30E, Rapid City, Manitoba, Canada. The site survey will be performed by Mechanicaland Controls/Electrical Application Engineers. The sections below outline the R-R supplied products thathave been reviewed during the site survey.

As part of the site survey, Rolls-Royce will thoroughly review the condition of the entire gas turbinepackage and associated system, and will recommend replacement based on the condition of theequipment.

In addition an obsolescence study will be conducted by said R-R Engineers on said products. Thestudy will be focused on critical parts and will not cover piping, cabling and structural assemblies.

3 COMPRESSOR

3.1 RFA Compressor (By TCPL)

3.1.1 The existing RFA compressor will be disconnected and stored at the existing site.

3.1.2 When the coupling and power meter are removed the compressor must have the shafts securedagainst axial movement. Tooling will need to be made to secure the compressor.

3.1.3 Compressor blocking needs to be welded between the two side feet and the rear foot. The originalsupports were solid steel blocks about three inches square, however heavy three inch angle ironshould be sufficient. These supports need to be in place if the compressor is to be moved andremain until the compressor is down on the sole plates at a new location.

3.1.4 Compressor needs wood blinds to be fitted on the compressor inlet and discharge all lube oil, sealgas and vent piping openings need to be blinded. Some preservative should be pumped into thebearings before it is blanked off for storage.

3.2 RFB Compressor

3.2.1 The RFB compressor will need to have piping work made from the existing interconnecting pipingfrom the mineral lube oil system. The existing mineral lube oil system will be retained and reused.

3.2.2 RR shall provide details on the foundation to Focus (DHP) for construction of the new facility.

19.3 The large tooling for the compressor and the PT for removing the bundle and the rotor are locatedon the deck above the suction pipe, The flushing manifold for the GG and the small PT andCompressor tooling is located in the small gray cabinet located under the exhaust; this is where thealignment tool that should be attached between the front support and mount ring is located. Theshipping bearings for the PT and axial travel tool are located in the aluminum box located in front ofthe gas filters. The river hawk hydraulic pumps, the GG shipping bag and the shims for the bellmouth to adjust the gap if required are located in the cold storage building.

20 CROSS SITE AND INTERCONNECTING CABLING

20.1 During the removal of the unit, cross site and interconnecting cabling will be the responsibility ofTCPL. This includes the following:

20.1.1 Procedure for wire preparation and gland packing GER0018, GEM0047

20.1.2 Skid edge (client) interface requirements GER0160

20.1.3 Signal separation requirements for panels, packages, and cross site wiring. GER0198

20.1.4 Wire, Conduit, Glands and cable tray procurement. GER0018, GER0070

20.1.5 Consumables procurement such as wire ties, heat shrink, gland packing material, torque sealantetc.

20.1.6 Conduit and cables labeling

20.1.7 Grounding requirements

20.1.8 RR will provide the EMV controller and UCP. TCPL will be responsible for the cabling from theUCP to the EMV controller and the cabling from the EMV controller to the EMV. This wouldinclude Device-Net communications cable. Cabling specifications will be provided by RR throughstandard GERs.

Note: When the removal activity is initiated, Cross site wiring will need to be disconnected fromthe on skid junction boxes. Wires need to be properly bundled and labeled for re-assembly ifcustomer’s expectation is to re-use them.Current TCPL scope of work is to replace all cross-site cabling at new facility. Refer to electricalinterface drawing for junction box numbering and wiring termination points.



September 2014






21 ON SKID WIRING

21.1 RR reviewed the condition of the on skid wiring, instrumentation, and all related package

components. The wiring was in proper condition, well segregated, followed protocols for shieldingand grounding.

21.2 Terminals seemed to be in good condition and will not need attention

21.3 All devices seemed to be in proper working order from the screen snapshots that were taken of theunit.

21.4 A package layout was sketched – See Appendix B

21.5 If during commissioning of the units the wiring is deemed unusable for any reason it will be theresponsibility of the customer to replace.

22 POWER REQUIREMENTS

22.1 24VDC, 110 VAC 60 Hz. Same as existing power requirements

25.2 TE214 was jumped out. TCPL said RTD was bad and never replaced due to unit running less than1 % of time.

25.3 Junction box FC was never installed. The valve command was landed in junction box L on the fuelmini skid and pressure transmitter 63JFCT (PDT-159) was a direct run back to the UCP. The directrun needs to be taken into consideration when TCPL layouts cross site cabling.

26 RECOMMENDATIONS

26.1 The customer has a Mark 3 GGLO console upgrading to the new PMP GGLO would be a

advantage to the customer from a maintenance and reliability standpoint

26.2 The customer PT and Compressor LO system has only one pump and use’s the aux drive to supplythe oil, converting this tank to a design like the new LO systems with two motors and pumps wouldupdate their system, removing the aux drive increases there power by removing all the gears andthe pump, and from a maintenance position it removes the chance for gear failure or bearings goingbad making it a more reliable unit.

26.3 Humidity and Ambient Temperature setup to be upgraded to current baseline design.

27 ACTION ITEMS

27.1 Rolls-Royce (RR)

27.1.3 RR shall verify if new coupling is to be supplied.

27.1.4 RR shall implement TCPL logic: Surge, Data array for DCS comms, uncontrolled venting logic,discharge check valve monitoring, recycle valve dP logic. RR has standard logic for Clock Synch,MCC Healthy, etc…

27.1.5 RR shall evaluate the positioning the new humidity and temp probes to determine if they aremounted in the correct position or if they need to be repositioned per the base line practice. Thiswould also include evaluating the necessity of a second set of transmitters as per the baseline.

This is part of the proposal and is included.

27.1.6 RR to investigate the need and the necessity of the temp indicator and advise TCPL. 26GGSA&B(TE-195A) causes unit to shutdown. Customer has to run fans in order for the unit to run.

27.1.7 TCPL has modified the containment shield for access to the GG in 3 places. RR needs to reviewfor potential Red Top Issue
