Location and Spacing of Outlets. The pier locations of ships potable
water connections may be determined by the data defined in APPENDIX C. Refer to
Chapter 2 for a description of methods to be used in establishing shore-utility station
spacing on piers and wharves.
Specific Ship Requirements
CV and CVN Ship Requirements (All Classes). Design systems as
specified above except provide a 101.6 mm (4-in) branch line, a 101.6 mm (4 in)
reduced pressure backflow prevention device, and an outlet assembly at outlet locations
3 and 4 of Figure 3-6. Provide a 101.6 mm to 63.5 mm (4-in to 2-1/2 in) reducer for
each location to allow the use of these outlets by ships other than carriers.
LHA and LHD. Design systems as specified for CV/CVN class ships
except provide dual outlets at each utility connection group, one 101.6 mm (4-in)
reduced-pressure backflow prevention device, and an outlet assembly near the center
of the berth. Provide a 101.6 mm to 63.5 mm (4-in to 2-1/2 in) reducer to allow use of
the 101.6 mm (4 in) outlet with other ships.
Additional Requirement for Nuclear-Powered Ships. A "pure" water
supply as defined by NAVSEA is required for all nuclear-powered ships. Due to the
quantities involved and the problems of contamination and quality control, tank truck
delivery will normally be used rather than the installation of piping and outlets on the
pier. Location(s) of the tank truck must be coordinated with all other pier features.
Coordinate with the cognizant NAVFAC EFD/EFA OR USACE DISTRICT.
Quality. Refer to MIL-HDBK-1005/7A. The quality of water must meet or
exceed the requirements of 40 CFR, Part 141, U.S. Environmental Protection Agency's
National Primary Drinking Water Regulations and the National Secondary Drinking
Metering. Provide metering of potable water supply to piers or groups of
piers unless instructed otherwise. See paragraph 2-5. Use compound-disc or
magnetic-flow meters to achieve a high range of registration.
POL SYSTEMS. Refer to MIL-HDBK-1022A. Fuel and lube oil
connection locations on various ships are defined in APPENDIX C. Pier fueling
connections and hoses must be kept a minimum of 7.6m (25 ft) away from any possible
ignition sources, such as pier power outlets, telephone terminal panels, and fire alarm
equipment. Required POL connection sizes must be obtained from specific ship data
available from NAVSEA. General requirements for pipe hangers and support
assemblies (paragraph 2-4.1.3) and for metering (paragraph 2-5) are applicable.
Identify POL outlets on piers and wharves and color-code in accordance with Chapter 6.
POL piping systems also require special consideration for protective coatings and
cathodic protection systems. See paragraph 2-4.4. Refer to military specifications MIL-
C-52404B, Connection Hose, Fire and Water, and MIL-S-12165F, Strainer Suction, Fire
Hose, and Strainer Suction, Hose for POL connection types. Consult with the cognizant
