vessel and tidal changes, without damage to the arm. Provide
a hydraulic power assist system for operating loading arms
larger than 8-inch (200 mm) nominal size. Equip the end of
the loader to be connected to the ship's manifold with an
insulating section, a standard ANSI forged steel flange, and a
steel quick coupling device, manually or hydraulically
operated. Refer to NAVFAC Drawing No. 1403997. Consider
breakaway couplings for locations with strong current.
5.8.2
Fuel Hoses. Loading/off-loading arms are the
preferred method to be used. Provide a facility for storing
and protecting the hose as near as practical to the pier if
hose is provided in lieu of loading/off-loading arm.
5.8.3
Submarine Fuel Hoses. Provide submarine fuel hose
where offshore moorings are used. Use heavy duty, smooth
bore, oil and gasoline, marine cargo, discharge hose rated for
a working pressure of not less than 225 psig (1550 kPa) and
built-in nipples with Class 300 flanges with stainless steel
bolts and Monel nuts. Hoses should be U. S. Coast Guard
certified.
5.8.4
Meters. Provide a turbine or positive displacement
meter for each dispensing outlet that might be used
simultaneously. With the approval of the appropriate Service
Headquarters, use portable meters where fueling operations are
intermittent. Also consider the use of alternative
technologies such as ultrasonic meters. Require temperature
compensation feature at each meter used for custody transfer.
5.8.4.1
Positive Displacement. Require flange-connected,
cast steel bodied positive displacement meters of the desired
pressure and flow rating for the applicable service
requirements. Ensure meter has temperature-compensation,
adjustable calibration, register and pre-set capabilities.
Ensure meter accessories are compatible with either the
mechanical or electronic support equipment selected. Provide
an accuracy of plus or minus 0.5 percent when used for custody
transfer. Consult the appropriate Service Headquarters for
requirements for the meter to communicate to a remote location
or equipment. Consider the use of a card-operated or key-
operated data acquisition system. Cards or keys, as
appropriate, are coded to identify the receiver of the fuel
and to allow access to the fuel. The quantities taken are
