A machinery engineer’s job was accurately described by this ad, which ap Personable, well-educated, literate individual with college degree in any form of engineering or physics to work . . . Job requires wide knowledge and experience in physical sciences, materials, construction techniques, mathematics and drafting. Competence in the use of spoken and written English is required. Must be. willing to suffer personal indignities from clients, professional derision from peers in more conventional jobs, and slanderous insults from colleagues.

Job involves frequent physical danger, trips to inaccessible locations throughout the world, manual labor and extreme frustration from lack of data on which to base decisions.

Applicant must be willing to risk personal and professional future on decisions based on inadequate information and complete lack of control over acceptance of recommendations . . . peared in the classified section of the New York Times on January 2, 1972: Well, that was in 1972. Since then, however, the job has not become any simpler.

The cost of machinery outages and repairs has escalated. The prerequisites required to be able to perform as a machinery engineer could even be expanded thus:

A knowledge of stress analysis, measurement techniques, instrumentation, vibration analysis, materials, machine shop procedures, fluid flow, rotor dynamics, machinery field erection and startup procedures, and an understanding of effective maintenance management.

This list is by no means complete. And since very few of us feel absolute master of all of these areas, we seek guidelines, procedures, and techniques that have worked for our colleagues elsewhere. Collecting these guidelines for everymachinery category, size, type, or model would be almost impossible, and the resulting encyclopedia would be voluminous and outrageously expensive.

Therefore, the only reasonable course of action has been to be selective and assemble the most important, most frequently misapplied or perhaps even some of the most cost-effective maintenance, repair, installation, and field verification procedures needed by machinery engineers serving the refining and petrochemical process industries.

This is what my colleagues, Heinz P. Bloch and Fred K. Geitner, have succeeded in doing. Volume 3 of this series on machinery management brings us the know-how of some of the most knowledgeable individuals in the field. Engineers and supervisors concerned with machinery and component selection, installation, and maintenance will find this an indispensable guide.

Here, finally, is a long-needed source of practical reference information which the reader can readily adapt to similar machinery or installations in his particular plant environment.
