tailieunhanh - Handbook of Reliability, Availability, Maintainability and Safety in Engineering Design - Part 45

Handbook of Reliability, Availability, Maintainability and Safety in Engineering Design - Part 45 studies the combination of various methods of designing for reliability, availability, maintainability and safety, as well as the latest techniques in probability and possibility modelling, mathematical algorithmic modelling, evolutionary algorithmic modelling, symbolic logic modelling, artificial intelligence modelling, and object-oriented computer modelling, in a logically structured approach to determining the integrity of engineering design. . | Analytic Development of Availability and Maintainability in Engineering Design 423 Q10. Are sharp bends causing forceful impingement present Q11. Are stagnant zones present that may hold the process fluid after flushing Q12. How complex is the equipment Q13. Are alignment adjustment procedures needed on installation replacement Q14. Is any special equipment required to make the adjustments Q15. Do components have many state changes . opening closing of valves Q16. Is the equipment novel in design or application Q17. Do components have arduous sealing duties Q18. Are special materials used Maintainability checklist Q1. Will catastrophic failure be evident in the control room Q2. Will degraded failure be evident from the control room Q3. Time period of degraded failure detection Q4. Does maintenance require protective clothing due to hazardous substances or hot equipment or does the equipment need time to cool down Q5. How easy is it to isolate equipment Q6. What method of isolation is required Q7. What area of plant needs to be isolated Q8. Is pressure release and drainage including purging and venting provided Q9. Is electrical isolation of equipment required Q10. Is scaffolding required for maintenance Q11. Can scaffolding be erected by maintenance personnel or by contractors Q12. Is there adequate space to build scaffolding Q13. Is there adequate space to manoeuvre while maintenance is taking place Q14. How is the equipment lifted Q15. Whatever lifting equipment is used are there any problems foreseen Q16. Does other equipment need to be removed before access can be gained Q17. Is visual access to the fault good enough to carry out maintenance Q18. Is the physical access good enough to carry out maintenance System Performance Analysis and Simulation Modelling Section considered system performance within the context of designing for availability which can be perceived as the combination of a system s process capability with regard to the .
