to be used in establishing shore utility-station spacing on piers and wharves. Hose valve
manifolds should be provided in sufficient numbers such that all parts of the ship can be
reached by at least two 30.5 m (100 ft) hoses. For spacing in drydocks, refer to UFC 4-
213-10.

Outlet Design. See Figure 3-4. The typical outlet should consist of a
152.4 mm (6 in) branch main and riser feeding a manifold arrangement of three 63.5
mm (2-1/2 in) and one 101.6 mm (4 in) valved hose connections. Where portable
pumping systems are used, standpipe connections may be provided on some (or each)
of the outlet risers for connection to the portable pumping system discharge hose. For
certain large ships, the above outlet requirements should be modified as defined in
paragraph 3-3.5. Provide four 101.6 mm (4 in) valved hose connections in a manifold
arrangement at the outboard end of large piers. These outlets are to serve fireboat or
large-volume portable-pump connections. Where berthing is designed exclusively for
tugboats, work boats, or other small craft having a "Salt Water From Shore" requirement
of not more than 39.4 l/s (625 gpm), properly spaced 101.6 mm (4 in) risers having two
to three 63.5 mm (2-1/2 in) connections may be used in lieu of the above. All
connections should be protected by a chained cap. At each designated pier in each
naval station where oceangoing U.S. merchant and foreign ships are expected, provide
two international shore connections. See Figure 3-5.
3-3.4.5
Materials and Installation Criteria. Pipe and fittings should conform to
MIL-HDBK-1005/7A, Water Supply Systems, as applicable to piers and wharves. Use
pipe, fittings and valves pressure-rated at 1724 kPa (250 psi) minimum. Hose threads
should be National Standard hose-coupling threads, 7-1/2 threads/inch, or as approved
by the cognizant Fire Protection Engineer. Materials for valves should conform to
requirements for pumps as defined in paragraph 3-3.3.5. For piping on a pier or wharf,
evaluate the relative advantages of cement-lined ductile iron versus cement-lined steel
pipe with an extruded polyethylene or polypropylene exterior coating. An ultra violet
inhibitor must be used in polyethylene coatings that will be exposed to sunlight. For
coated pipe, use polyethylene heat-shrinkable sleeves and/or tape wrapping at joints
and fittings. Provide pipe hangers and associated support assemblies in accordance
with paragraph 2-4.1.3. Provide means of pipe movement due to thermal expansion,
preferably by the use of expansion loops and offsets. Also, provide for differential
movement of piping at pier expansion joints. Piping and outlets must be identified and
color-coded in accordance with Chapter 6.

CV, CVN, LHA, and LHD Requirements (All Classes). At existing
installations where insufficient saltwater pressure exists, the pressure should be
increased to provide 1034 kPa (150 psi) residual pressure at the pier outlets. Pump-
discharge pressure must be sufficient to provide the required residual at the rated
design flow. The following special requirements apply to these large class ships:
