11.2.4 REMOVING OLD FITTINGS.  If a hose fitting must be replaced as a
result of damage, or if the hose is damaged and part of it must be removed
and discarded, the steps below should be followed:
a.  Place the end of the hose from which the fitting is to be removed
in two 6-inch pipe vises on the work bench.  Cut off the hose to remove the
fitting, using a 10-point carpenter's saw to make a neat, square cut; no
more than 6 inches of hose needs to be taken off in this step.
b.  Place the cut hose end with fitting on the work bench or deck and
cut the hose-clamping bands with a band-cutter or snips; slip hose end off
fitting.
c.  If difficulty is experienced in removing the hose end from the fit-
ting, the hose is cut off, using a sharp knife and/or snips.
d.  If the fitting is not defective, it may be replaced on the hose,
following the steps outlined in 11.2.3; if the fitting is faulty, a new fit-
ting should be placed on the hose, following the steps in 11.2.3.
11.2.5 SHORT HOSE LENGTHS.  Short lengths of hose created by cutting out
defective sections or through other repair procedures should be fitted with
couplings and saved.  The use of short lengths with standard 50-foot lengths
often will simplify the job of vessel connection.  The optimum hose length
for connecting ships to pier risers for transfer of ships' sewage is the
shortest length necessary to make the connection.  This same optimum length
applies to ship-to-ship sewage transfer connection.
