Specifications include, but are not limited to: CP SYSTEMS CLASSIFICATION 3.1 Unit 5 segment (combined cycle): 3.1.1 An impressed current CP system with two air-cooled rectifiers, Rectifiers #1 & #2, with 25 distributed mixed metal oxide anodes arranged on three circuits where test stations 21 through 44 are installed along the piping routes for monitoring. 3.1.2 An impressed current CP system with one air-cooled rectifier, Rectifier #3, and deep anode groundbed used to supplement the current of the CP system described in item 1.3.1.1. The negative cable of is connected to the closed cooling water supply piping. 3.1.3 An impressed current CP system with one air-cooled rectifier, Rectifier #4, and deep anode groundbed used to protect the fuel gas piping main header into the plant. The negative cable of is connected to the 20-inch gas piping. 3.2 Units 1-4 segment (gas turbine original installation): 3.2.1 An impressed current CP system with four air-cooled rectifiers, S14-CP-CPR-1 through -4, and an unspecified number and type of anodes. This segment of the CP system has only two test stations. 3.3 Units 6 and 7 segment (gas turbine expansion): 3.3.1 An impressed current CP system with one air-cooled rectifier, Rectifier #67, with 14 distributed mixed metal-oxide tubular anodes, where test stations 1 through 14 are installed along the piping routes for monitoring. 7.2 The Contractor shall provide the following: 7.2.1 A single POC through which all AE requests will be coordinated. 7.2.2 All personal safety equipment for testing personnel, including hard hats, safety eyewear, work gloves, etc. Contractor work requirements are detailed in Attachment 3. All personnel working at the site shall watch a SHEC safety video prior to commencing any work (to be coordinated with AE Project Manager). 7.2.3 All field technical services, tooling, consumables, equipment, instrumentation and technical supervision to perform the testing. 7.2.3.1 Tooling or equipment that requires calibration (e.g. meters, torque wrenches, etc.) shall be in calibration prior to test commencement. No out-of-calibration or failed-calibration tooling may be used.
