11. Equipment management program. Startup problems, solutions, and design changes should be clearly documented and available for a good equipment management plan. All items that can reduce Life Cycle Costs (LCC) should be considered. These include:
a. Economic evaluation at the equipment-investment stage
b. Consideration of MP or maintenance-free design and economic LCC
c. Effective use of accumulated MP data
d. Commissioning control activities
e. Thorough efforts to maximize reliability and maintainability
12. Final implementation of PTPM. This stage involves the refinement of PTPM and the formulation of new goals that meet specific corporate needs.
Maintenance .epartment .equirements
To ensure the success of the PTPM program, the maintenance department must be well equipped and trained. The following six basic categories are prerequisite to the proper functioning of the Maintenance Department under the PTPM:
1. Training of personnel
2. Tools and equipment
3. Condition and life assessment
4. Spare parts inventory
5. Redesign for higher machinery reliability
6. Maintenance scheduling
.. Maintenance communication
8. Inspections
Training of Personnel
Training must be the central theme. The days of the mechanic armed witha ball-peen hammer, screwdriver, and a crescent wrench are gone. More and more complicated maintenance tools must be placed in the hands of themechanic, and he must be trained to utilize them.
People must betrained, motivated and directed so that they gainexperience anddevelop, not into mechanics, but into highly capable techni-cians. While good training is expensive, it yields great returns. Machineryhas grown more complex, requiring more knowledge in many areas. Theold, traditional craft lines must yield before complicated equipment maintenance needs. A joint effort by craftsmen is necessary to accomplish this.
I. Type of Personnel
a. Maintenance .ngineer.In mostplants, the maintenance engineer is a mechanical engineer with training in the turbomachinery area. His needs are to convert what he has learned in the classroom into actual hands-on solutions. He must be well versed in a number of areas such as performanceanalysis, rotordynamics,metallurgy, lubricationsystems, and general shop practices. His training must be well planned so that he can pick up

these various areas in steps. His training must be a combination of a hands-on approach coupled with the proper theoretical background. He should be well versed in the various ASME power test codes. Table 21-2 is a listing of some of the applicable codes for gas turbine power plants. Attendance at various symposiums where users of machinery get together to discuss problems should be encouraged. It is not uncommon to find a solution to a problem at these types of round table discussions.
