CHAPTER 2
GENERAL UTILITY REQUIREMENTS
2-1
SHIPS DEMANDS. Ships utility demands and other pertinent data for
individual ships utilities are available from SCDB (see paragraph 1-1.2.) The designer
must access this information in order to obtain the latest design data regarding dockside
utilities for all ship services. In general, ship utility demands for active berthing are
based on the ship's complement without deployed forces such as air wings or marine
troops. Diversity factors are provided for use in determining demand in multiple
berthing. If the designer is basing the project design on a specific ship that is not
included in SCDB, use data from a similar ship, or obtain the expected demand from
NAVFAC EICO or USACE. For graving drydocks, refer to UFC 4-213-10. This
information is for use at new facilities and for use in additions, modifications, and
replacements at existing facilities. While means of diversification are provided for
multiple ships and multiple piers by these diversity factors, metered data from existing
facilities and ships should be used for planning and design whenever such data are
available.

UTILITY-CONNECTION LAYOUT. Figure 2-1 shows the dimensional
relationships normally encountered in placement of shore utility connections. SCDB
provides size/shape data for typical ship hulls and dimensioned reference points that
define the ship's utility connection locations. Ideally, the locations of shore utility
connections for a given berth would simply correspond to their respective connection
locations on the ship to be berthed. In practice, however, utility-connection locations
can never be ideal, due to largely nondedicated berthing, interference with other pier or
wharf activities, other deck equipment, and the grouping of connections. The designer
must optimize the location of all utility outlet assemblies based upon the projected
berthing mix.
2-2.1
Connection Grouping. Utility connections should be confined to specific
locations along a shore facility so that interference with line handling and other facility
operations is reduced. Connections may be in large groups to encompass all utilities, or
may be in subgroups, such as the following:
Freshwater, saltwater (if required), steam, and compressed air;
Electrical power and communications;
Sewer and oily waste; and
POL, when required.
