Provide description and analysis of the options available to provide the
required protection such as: (1) permanent system to supply the entire
demand; (2) portable pumping systems(s) dedicated or otherwise; and (3)
combinations of items (1) and (2). All existing Navy assets must be
included in the analysis including any existing permanent systems.
Provide a life cycle cost analysis for all viable options on a site-specific
basis. Perform the analysis in accordance with NAVFAC P-442, Economic
Analysis Handbook. The analysis must take into consideration the costs
of owning and operating all pertinent plants, both on ships and ashore.
Make recommendations for the best system to meet the required demand
as based on consideration of the special conditions(s) or hazards(s) and
on the life cycle cost analysis.
The demands and pressure parameters of an approved permanent salt or
nonpotable water system should be designed as described in paragraph
3-3.2 and all subparagraphs.
3-3.2
Demands and Pressure Requirements. Berthing facilities should
conform to the requirements specified below. Note that the requirements differ for
overhaul and drydock berthing versus those for active berthing.
3-3.2.1
Drydock, Repair and Inactive Berthing. Nonpotable or saltwater supply
should be furnished at drydocks, piers, and wharves as described below. Requirements
for selected ship classes are defined in SCDB. For ships not included in SCDB, use
data from a similar ship, or obtain the expected demand from NAVFAC EICO. The
following criteria should also apply.
Drydock. Provide sufficient saltwater to meet the requirement of the ship
with the highest saltwater demand anticipated to be docked at the
drydock. Use the "Total Demand" quantity listed in SCDB. Refer to UFC
4-213-10 for additional requirements at drydocks.
Repair Berthing. Provide sufficient saltwater to meet the "Total Demand"
requirement defined in SCDB for the largest ship to be berthed at the pier
plus the aggregate cooling/flushing demand of all remaining ships at the
pier, and then multiplied by the diversity factors given below. In general,
allow 63 l/s (1000 gpm) minimum for piers serving frigate ships and larger
and 32 l/s (500 gpm) minimum for piers serving ships smaller than
frigates. Also, do not include nested ships.
