ISA Training course catalogue released
The ISA Training Institute has released its latest course catalogue, detailing more than 300 instructor-led, CD-ROM, online, web-based, and video courses, from August 2003 to March 2004
The updated book includes enhanced techniques and insights along with new chapters dealing with computerised PM systems.
A recent ARC Advisory Group survey on plant automation maintenance reveals that the majority of plant maintenance budgets is directed to automation assets, including process automation systems (26%), field devices (25%), and control valves (19%).
These three categories combined represent 70% of a total maintenance budget, which typically could reach USD40 million for a large refinery.
Good PM saves money over a product life cycle.
Patton comments, "Everything will fail sometime, whether biological, electrical, electronic, hydraulic, mechanical, nuclear, optical, and especially humans.
The best answer is to avoid the need to fix".
"Preventive Maintenance" addresses major types of maintenance; advantages and disadvantages of PM; designing a PM program; economics of PM; nondestructive testing; scheduling; metrics; and data issues.
New technology has improved equipment quality, reliability and dependability by installing fault-tolerant, redundant components, and self-adjustments, as well as replacing hydraulic and mechanical components with more reliable electronic and optical operations.
However, many components can still wear out, corrode, become punctured, vibrate excessively, become overheated by friction or dirt, or be damaged by humans.
Preventive maintenance allows planned work when production is not pushing, instead of expensive emergency repairs that may be required under disruptive conditions and result in lost revenue due to halted production.
"Preventive Maintenance" (ISBN 1-55617-875-1) will be available for purchase on the ISANetwork.
