SECTION 672-1

3.4
Storeroom gross volume. Storeroom gross volume is the volume of the
compartment within the boundaries of the bulkheads and shell plating from the
deck or deck grating to the stowage height. For refrigerated spaces it is the
volume within the boundaries of the bulkhead insulation and sheathing from the
top of the deck grating to the stowage height.
3.5 Storeroom net volume. Storeroom net volume is the volume of the
compartment available for the material to be stowed. It equals the sum of the
net stowage capacity of each stowage aid within the space, including bulk
stowage.
3.6 Stowage aid. Stowage aid is any piece of equipment or fitting used
for stowage, including bins, drawer shelf units, lockers, modular drawer
stowage (MDS) cabinets, reels, shelving clips, jackrods, battens or gratings.
3.7 Gross stowage capacity. Gross stowage capacity is the total stowage
volume provided by the individual stowage aids.
3.8 Net stowage capacity. Net stowage capacity is the usable stowage
volume provided by individual stowage aids.
3.9 Stowage height. Stowage height is the clear height to which stores
are to be stacked. For ship storerooms, it is defined as 6 feet 6 inches above
the deck or deck gratings when provided. For refrigerated storerooms, it is
defined as 6 feet above the deck gratings. However, a minimum of 6 inches of
clear space is required above the bulk stowage material. Hence, the stowage
height shall be reduced where necessary to meet the required clear space.

GENERAL REQUIREMENTS
4.1 Information factors. The following information shall be calculated
and provided for each storeroom:
(a) Deck area.
(b) Storeroom gross volume.
(c) Net stowage capacity and number of each type of stowage aid
in the storeroom.
(d) Storeroom net volume.
(e) Percent of storeroom utilization.
4.2 Computations.
Computations shall be as follows:
(a) Deck area. To find the deck area, multiply length times width
of deck within the boundaries of the storeroom bulkheads or the
bottom of the shell plating. Measurements shall be as shown on
figure 1.
(b) Storeroom gross volume. To find the storeroom gross volume,
multiply the deck area times the stowage height of 6 feet for
refrigerated storerooms or 6 feet 6 inches for all other
storerooms.
