 Section 2.
SURFACE VESSELS
7.2.1 SHORE FURNISHED HOSES. Because of space requirements, the possibility
of contamination, and the need for special cleaning facilities, 4-inch sewage
hoses for ship-to-ship connection normally are not carried aboard vessels.
Because the same hose is used for making ship-to-shore connections, the hose
is stored ashore at the sewage hose storage facility. ip-to-ship sewage
Sh
hoses are identical to ship-to-shore sewage hoses except that the former
have female connections at both ends and are shorter in length.
7.2.2 SHORE CREW TASKS. It is the responsibility of the shore crew to take
the proper amount of clean hoses to the assigned berth just before arrival
of the vessels. If the hose is to be removed manually from the transport
vehicle, the shore crew should remove the hose from the vehicle and arrange
it in straight lines along the pier. This step applies to both coiled col-
lapsible and noncollapsible rubber hoses. A trailer mounted, powered hose
reel also may be used for delivery of collapsible or noncollapsible rubber
sewage hoses, in which case the hoses are unreeled directly to the ship as
they are lifted.
a. Sizing Hoses. The shore crew must know in advance the proper hose
length for reaching from the riser on each outboard ship to the riser on the
next inboard ship; to facilitate this, the shore activity may cut hoses to
lengths less than 50 feet. Hoses will be passed up to the ships' crews in
the proper lengths by linking together sections on the pier during delivery,
in cases where the hose is being deployed manually. If the hoses are
delivered from coils on the transport vehicle, or directly from a powered
hose reel, they will be uncoupled at the proper places to obtain the correct
number of feet in each length delivered.
b. Passing Hoses from Pier to Ship. As soon as the outboard ship is
tied up, its hose handling crew proceeds to the pier side of the inboard
ship. At least four men should be in this group. A heaving line is passed
down to the shore crew on the pier. The shore crew bends the heaving line
on the female end of the first length of hose to be passed up to the ship,
using a clove hitch just above the fitting and a half hitch on the fitting.
By heaving in on the line, the ship crew manually lifts the first length of
sewage hose to the ship's deck. During this step, the shore crew guides the
hose off the pier. If the hoses are being handled manually, the hoses are
laid out in straight lines on the pier and guided. When the powered hose
reel is used, the reel should be operated at the same rate at which the hose
is being pulled aboard ship.
In delivering hoses for ship-to-ship connection, the shore crew's task
is limited to passing the proper number of hose lengths to the ship's crew
on the vessel nearest the pier. The steps described above are repeated
until a sufficient number of sewage hoses have been passed to the inboard
vessel so that it can make the necessary number of ship-to-ship connections
for the outboard vessel.
