ENGINEMAN 1 & C
number of people who can work EFFECTIVELY
on a job or on part of the job at the same time.
Doubling the number of personnel will not cut
the time in half; instead, it will result in confu-
sion and aimless milling around.
The best way to estimate the time and the
number of personnel needed to do a job is to
divide the total job into the various phases or steps
that will have to be done, and then estimate the
time and the personnel required for each step.
Estimating the materials required for a repair
job is often more difficult than estimating the time
and labor required for the job. Although your
own past experience will be your best guide for
this kind of estimating, a few general considera-
tions should be noted:
1. Keep accurate records of all materials and
tools used in any major repair job. These records
serve two purposes: first, they provide a means
of accounting for materials used; and second, they
provide a guide for estimating materials that will
be required for similar jobs in the future.
2. Before starting any repair job, plan the job
carefully and in detail. Make full use of manufac-
turers technical manuals, blueprints, drawings,
and any other available information, and find out
in advance all the tools and materials that will be
required for the accomplishment of each step of
the job.
3. Make a reasonable allowance for waste
when calculating the amount of material you will
need.
TRAINING
By the time you have reached the E-5 or E-6
level, you have acquired many skills and a large
amount of theoretical knowledge. Among other
things, you have learned about
Construction details, operating principles, and
operating characteristics of all types of naval
propulsion plants and associated engineroom aux-
iliary machinery; propulsion plant layout and pip-
ing system arrangement; theory of combustion,
theory of energy transformations, and factors
governing engineroom and fireroom efficiency;
nature and theory of engineroom operations;
operational troubleshooting; engineering casualty
control; engineroom maintenance and repair;
characteristics of metals and alloys; tests and
inspections of main engines; characteristics and
tests of lube oil; and records, reports, and other
administrative requirements.
As you well know, this is only a partial list
of the skills and knowledge you must have in order
to qualify as an expert Engineman. But even a
very wide range of abilities and an extensive
theoretical knowledge will not, in themselves,
guarantee your success as an instructor.
TRAINING RESPONSIBILITIES
You must be technically competent before you
can teach others, but your technical competence
must be supplemented by the ability to organize
information, to present it effectively, and to
arouse and keep the interest of your trainees.
You will find excellent general information on
how to plan, carry out, and evaluate an instruc-
tional program in Military Requirements for Petty
Officer 3 & 2, NAVEDTRA 10056 (current edi-
tion) and in Military Requirements for Petty
Officer 1 & C, NAVEDTRA 10057 (current edi-
tion). The present discussion does not include
basic information of the type given in these
references; instead, it deals with some of the dif-
ficulties peculiar to the training of engineroom
and auxiliary personnel and some of the ways in
which you can overcome or minimize these
difficulties.
What kinds of things cause special problems
in the training of engineroom personnel? For one
thing, the interrelationship of propulsion plant
operations. Each person must be trained to per-
form not only as an individual but also as a
member of a team. Take for instance the duties
of the watchstanders. They are very closely
related, and the actions taken by one person de-
pend in some way upon the actions taken by other
persons.
From a long-range point of view,
however, the teamwork required for engineroom
operations can actually be turned to a training
advantage. As a person is being trained for one
specific duty, he must of necessity be learning
something about the other duties. As a rule,
therefore, the first part of a persons engineroom
