CHAPTER 7
STORAGE AFLOAT AND ASHORE
For stores to be useful to your ship they must
be stored in such a way that both protects the
stores from deterioration and at the same time
protects the ship from any dangers presented by
having these stores on board. In this chapter we
will discuss some of the procedures to be followed
when storing and handling stores both aboard ship
and in warehouses. Safety procedures for mate-
rials handling were discussed in Storekeeper 3 & 2
and should be reviewed with this chapter.
DEFINITIONS
Some terms used in storage should be defined
before we go any further.
Warehousing—The scientific and economical
receipt, storage, and issue of materials for
safekeeping and rapid availability. This term
refers to the detailed application of the principles
of space layout and location of materials, or
assignment of a particular item to a specific
storage area at a terminal supply point.
Measurement Ton— Usually 40 cubic feet.
This is also called a ship ton.
Measurement Cargo—A term used to describe
cargo that measures more than 40 cubic feet per
ton.
Deadweight Cargo— A term used to describe
cargo that measures less than 40 cubic feet per ton.
Storage Factor— A term applied to cargo
indicating the number of cubic feet of space oc-
cupied by one long ton of a commodity packed
for shipment. It is arrived at by dividing the
volume of cubic feet by the weight of cargo in long
tons (2,240 pounds); that is, SF = V/W.
By knowing the storage factor of a commodity
and the available cubic feet of storage, the total
weight to fill this volume can be determined. As
an example, a light tank, weighing 12.73 tons, that
occupies a volume of 942 cubic feet would have
a storage factor of:
In practice, extensive tabulations are available
indicating the storage factor for almost any con-
ceivable commodity or a representative group.
STORAGE AFLOAT
Storage of material afloat requires a knowl-
edge of the factors to be considered in determin-
ing the storage location best suited for the stores,
the precautions to be taken to make sure of the
safety of both the stores and the ship, and the
accessibility of the stores.
BASIC STORAGE CRITERIA
Materials in shipboard storerooms and other
storage areas should be arranged to accomplish
the following objectives:
l
l
l
l
l
l
Make sure of maximum use of available
space
Provide orderly storage and ready ac-
cessibility
Prevent damage to the ship or injury to
personnel
Reduce the possibility of material loss or
damage
Facilitate and make sure of issue of the
oldest stock first (by the first in, first
out [FIFO] method)
Facilitate inventories
The preceding criteria and other instructions in
this part provide basic guidelines that, if observed
with a commonsense approach, will enable store-
room SKs to achieve optimum storage efficiency.
(See the NAVSUP Publications 486 and 487 for
specific storage instructions regarding subsistence
and ship’s store items respectively.)
