g.  Hose handling crew members continue hauling the hose aboard ship
from the pier and moving it across the ship as it is being transferred to
the outboard vessel.
h.  When the forward end of the hose arrives at the outboard ship's
sewage riser, it is connected immediately to the riser by means of the cam-
lock coupling.
i.  The hose handling crew members remaining on the inboard ship con-
tinue to move the hose across the deck until the aft end of the hose is
maneuvered adjacent to the outboard sewage riser on that vessel; during this
step, the hose is payed out over the side of the inboard vessel.  The hose
should not be permitted to loop between ships, as the weight of water in the
hose makes disconnection operations more difficult.
j.  The hose is connected to the sewage riser of the inboard vessel by
a member of that ship's crew; if the hose is collapsible rubber sewage hose,
it is arranged, tied off, and supported at either end in such a way that
kinking will be prevented as much as possible. This includes the use of
saddles on the railings of both vessels (old tire rims will serve as saddles
for hose support). Figure 7-3  illustrates use of old tire rim saddles.
k.  After the hose is securely in place at both ends, the valve on each
ship riser is opened by the crew members of each ship; this ensures that the
inboard vessel has completed its connection(s) to the pier sewer and has its
CHT system in the pump-ashore mode before the outboard vessel begins to pump
ashore.
10  If the newly arrived outboard ship has to connect more than one
sewage riser, the above steps are repeated for each sewage riser until the
ship is completely connected.
m. Upon completion of the above steps, the outboard vessel places its
CHT system in the pump-ashore configuration and begins pumping.
In many cases, several nesting ships will have to be connected at one
time, or sewage hoses for ship-to-ship sewage connection will have to be
moved across several ships before reaching a newly arrived outboard vessel.
The procedure outlined above for two nested vessels will be followed to move
the forward end of hose lengths to the second' vessel outboard from the pier.
Transfer of the hoses across additional intervening ships would take place
by following the same steps as outlined above in moving the hose from ship
to ship. When the forward end of the hose finally reaches the vessel to be
served, it is connected to the ship's sewage riser in the same manner, while
the aft end is connected to the riser of the next inboard ship.  Care is
taken throughout the hose transfer procedure to carry rather than drag hose
couplings across the vessels to prevent damage to the couplings and to the
ships.  For the same reason, ends of hose lengths must not be dropped over
the side between ships; this will result in severe damage to the couplings
as a result of impact against the ship's side.
In some cases, it may be impossible for an outboard ship to pump through
an inboard ship because of the lack of adjacent sewage risers on the inboard
