Hose connections must be 50.8 mm (2 in) unless instructed otherwise.
Each hose connection must include a shut-off valve, a 12.7 mm (1/2 in)
hose bleeder valve, and a hose connector. Threaded connections are to
be avoided in order to prevent loosening of joints due to hose tension.
Minimum pipe size of each rise assembly must be as follows:
NUMBER OF HOSES
RISER SIZE
CONNECTED TO RISER
MM (INCHES)
1
63.5 mm (2-1/2")
2
76.2 (3")
3 or 4
101.6 mm (4")

Specific Ship Requirements
3-1.6.1
CV and CVN Ship Requirements (All Classes). These ships are
normally berthed starboard side-to. Steam is provided to CVNs certified pure at 1034
kPa (150 psi). Galley and hot water requirements should be increased by 50 percent
where it is reasonable to assume that the ship's air wing may be on board.
3-1.6.2
Nuclear-Powered Submarine Requirements. Steam supply for nuclear-
powered submarines is not required at operational berths. For ship construction or
major repair activities, high-pressure steam at 13.8 to 27.6 MPa (2000 to 4000 psi) may
be required for test purposes. This supply may be from a permanent plant or from a
portable steam generator. The proper selection is dependent upon local weather
conditions. Evaluate each location on an individual basis. The cognizant NAVFAC
EFD/EFA OR USACE DISTRICT will approve.
3-1.6.3
Troop Carrier Special Requirements (LHA, LHD, LPD, LSD, and LST).
Provide steam service at 1034 kPa (150 psi) certified pure. For LHA, LHD, LPD, and
LSD increase galley and hot water requirements by 100 percent if it is probable that
troops will be aboard while at active berths.
3-1.6.4
Nested Ships. Maximum nested ships demand at shore connections is
8142 kg/h (17,950 pph) based on the requirements of nested CG-47s.
3-1.7
Shore-to-Ship Steam and Feedwater Requirements
3-1.7.1
Quality. Naval Sea Systems Command (NAVSEA) shore-to-ship steam
and feedwater quality standards are provided in NAVSEA S9086-AB-ROM-010, Naval
Ship's Technical Manual (NSTM), Chapter 220, "Boiler Water/Feedwater - Test and
Treatment", paragraphs entitled: "Shore Steam and Condensed Shore Steam Used as
Feedwater"; "Navy and Commercial Facility Shore Steam Certification Requirements";
"Shore Processed Feedwater (Demineralizers, Reverse Osmosis)"; "Shore Source
Feedwater Requirements"; and "Makeup Feedwater Demineralizer System". These
standards are given in Table 3-2 and Table 3-3.
