trip. During wartime or other emergency, the duration
and destination of the ship may not be known. The
supply officer must then load to capacity to provide for
the ship’s requirements for an indefinite period of time.
For most operating supplies, the supply officer has the
past records of what has been used. From these, a
balanced load that will provide the maximum days of
support can be calculated. But what about repair parts?
No one can predict when a bearing on the freshwater
pump will wear out or a vital part in the radar will fail.
This is where the COSAL takes over. Computers have
analyzed the failure frequency of parts used aboard
ships, and based on the equipment aboard your ship,
have developed an allowance of repair parts that you
should stock.
The key word in COSAL is COORDINATED.
Computers assemble a list of the allowed parts from the
hundreds of APL/AELs into lists of repair parts to be
stocked by the ship. These lists are prepared by the
activities and cover the equipments supported by them.
The preparation of these lists takes into account the:
installed equipment on board
quantity of each item of that equipment
failure rate of parts, and the
relative importance of these parts to the
operation of the equipment.
Thus, the COSAL, aided by experience and advice
from technical ratings, enables the supply officer to
stock the items that should be carried to meet the
requirements for repair parts.
Of course, the COSAL will not provide parts for
every equipment breakdown. To do this, you would
have to carry a complete set of spare equipment and
machinery in the storeroom. This is impossible.
Chapter 12 of this TRAMAN covers a system of
reporting that will greatly improve the effectiveness of
the COSAL, but the present COSAL is far superior to
any system previously used to provide repair parts
support for the equipment and machinery aboard ship.
The COSAL does not include:
Ship’s store stocks
Resale clothing
Subsistence items
Expendable ordnance
Recreational equipment
Hydrographic charts
Medical material
Printing equipment
Bulk fuels and lubricants
Repair parts for aircraft
These items are covered by separate outfitting and
load lists.
Flagship allowances are included in HME COSAL.
As you study this chapter, keep in mind that you
will use the COSAL for two main reasons: (1) To
identify repair parts and (2) To determine storeroom
allowances.
This includes the material in your
storeroom and the material requirements of
maintenance personnel. There is much more
information contained in the COSAL that you may use,
depending upon the type of job you are assigned to do.
If you are assigned to the supply support center or
repair parts storeroom, you must be able to use the
COSAL. How well you are able to use it will depend
on how well you understand the purpose and content of
each part.
Refer to the COSAL Use and Maintenance Manual,
SPCCINST 4441.170A series for detailed instructions
in its use.
STOCK LISTS AND CATALOGS
The use of stock lists and catalogs is fully explained
in chapter 4. As a Storekeeper you will be expected to
have a working knowledge of the stock lists and
catalogs on your ship.
The following is a brief
description of the types and purposes of regularly used
references.
Complete and accurate management data must be
available for requisitioning purposes and for effective
financial and inventory control of material. The ML-N
provides the basic management data. The related
publications were developed to supplement the ML-N
by providing additional management data and by
consolidating certain information for reference
purposes. The ML-N and related publications all have
the NSN as a common data element. Detailed
descriptions and information on the ML-N and the
related publications listed below are discussed in
chapter 4.
