Downtime Cost
Average CM downtime of the feed water pump =
20 hr/year.
Average CM downtime of the fire tube boiler =
30 hr/year.
Average CM downtime of the system auxiliaries =
10 hr/year.
Average down cost rate = 10000 $/hr
Total downtime cost rate = 600,000 $/year
Proposed saving downtime cost = 480,000 $/year
Spare Parts Program
The proposed spare parts program is shown in Table
13. This table shows that the spare parts for the plant
main components (feed-water pump, water tube boiler
ant steam turbine). Proposed spare parts program results indicate a saving of about 22.17% of the spare parts total
cost as compared with that of the current maintenance
(CM).
