Chapter 2—ADMINISTRATION, SUPERVISION, AND TRAINING
all the information you have available is a
manufacturer’s part number, then you must also
fill out and submit, along with the NAVSUP
Form 1250, a DD-1348-6 Form, NON-NSN REQ-
UISITION. For information on how to fill out
these supply forms, review Military Requirements
for PO 3 & 2, volume II of OPNAVINST 4790.4,
or ask your ship’s supply personnel for assistance.
Whenever you find it necessary to request
materials or repair parts, remember two things:
1. If at all possible, find the correct NSN for
each item requested. All materials now in the
supply system have been assigned an NSN, and
you should be able to locate them by using the
COSAL and the other sources of information
available to you such as the following:
a. NAMEPLATES on equipment supply
information regarding the characteristics of the
equipment. Nameplate data seldom, if ever,
include the exact materials required for repairs;
however, the information given on the
characteristics of the equipment and on pressure
and temperature limitations may provide useful
clues for the selection of materials.
b. MANUFACTURERS’ TECHNICAL
MANUALS are furnished with all machinery and
equipment aboard ship. Materials and repair parts
are sometimes described in the text of these
technical manuals; more commonly, however,
details of materials and parts are given on the
drawings. Manufacturers’ catalogs of repair parts
are also furnished with some shipboard equip-
ment; when available, these catalogs are a valuable
source of information on repair parts and
materials.
c. SHIPS’ PLANS, BLUEPRINTS, and
OTHER DRAWINGS available on board ship are
excellent sources of information on materials and
parts to be used in making various kinds of
repairs. Many of these plans and blueprints are
furnished in the regular large sizes; but lately,
microfilm is being used increasingly for these
drawings. Information obtained from plans,
blueprints, and other drawings should always be
checked against the information given on the
ship’s COSAL to be sure that any changes made
since the original installation have been noted on
the drawings.
2. Work informally with the supply depart-
ment personnel who are actually responsible for
identifying and requesting material. You have the
technical knowledge, and you know what you
need. If you cannot find the correct stock number,
however, your job is to give enough standard iden-
tification information, such as manufacturer part
numbers, and Allowance Parts List/Component
Identification Description (APL/CID) numbers,
so that supply personnel on board ship or ashore
can identify the item you want. Experienced
supply personnel are familiar with identification
publications and can help you to locate the cor-
rect stock numbers and other important identi-
fying information.
SHIP EQUIPMENT CONFIGURATION
ACCOUNTING SYSTEM (SECAS).—When the
structure or composition of either the ship or a
particular system or equipment on board a ship
is modified, this modification must be
documented. This action will ensure proper ac-
counting of configuration changes, and will help
improve supply and maintenance support
technical manuals, PMS coverage, updated
COSAL, etc., to your ship. SECAS is the
designated system responsible for maintaining the
configuration status reported by your ship.
Although the responsibility for identifying and
reporting these changes rests at all levels of the
command, the work center supervisor is respon-
sible for ensuring that the proper documentation
is completed and processed as described in volume
II of OPNAVINST 4790.4.
OPNAV Form 4790/CK, Ship’s Configura-
tion Change Form, is used to report configura-
tion changes at the individual equipment level.
SHIP-TO-SHOP WORK.—Many repair jobs
are designated by the ship or approved by the
repair activity as “ship-to-shop” jobs. In this type
of job, the ship’s force does a large part of the
repair work. For example, the repair or renewal
of a damaged pump shaft might well be written
up as a ship-to-shop job. The ship’s force will
disassemble the pump and remove the shaft. Then
the shaft and any necessary blueprints or technical
manuals are delivered to the designated shop of
the repair activity. After the shaft has been
repaired, or a new one has been made, it is
